We will also explore how to choose the right mattress sizes and size bed dimensions.Mattress Sizes and Bed Dimensions GuideIn the United States, the mattress’s width and length are traditionally measured in inches. Other countries have different sizes that are measured in centimeters.If you’re interested in measuring your own mattress, lay a tape measure from top to bottom and across its middle.MattressDimensions (Inches)Dimensions (CM)Crib27.25 inches by 51 inches69.2 cm by 129.5 cmSmall Single30 inches by 75 inches76.2 cm by 190.5 cmTwin38 inches by 75 inches96.5 cm by 190.5 cmTwin XL38 inches by 80 inches96.5 cm by 203.5 cmFull54 inches by 75 inches134.5 cm by 190.5 cmFull XL54 inches by 80 inches137 cm by 203.5 cmQueen60 inches by 80 inches152.5 cm by 203.5 cmOlympic Queen66 inches by 80 inches167.5 cm by 203.5 cmKing76 inches by 80 inches193 cm by 203.5 cmCalifornia King72 inches by 84 inches183 cm by 213.5 cmShop By Mattress Size Shop Twin Shop Twin XL Shop Full Shop Queen Shop King Shop Cal King Crib: 28 inches by 52 inchesRoom size requirements: 7 feet by 10 feetThe crib mattress only fits inside a crib and is regulated by the federal government for safety reasons.This size mattress is usually medium firm and no thicker than 6 inches. To sleep comfortably on a crib mattress, a child must be shorter than 3 feet. If the child is taller than 3 feet, consider buying a small single mattress.Small Single: 30 inches by 75 inchesRoom size requirements: 7 feet by 10 feetThe small single mattress is excellent for toddler beds. The small single mattress is a standard mattress size, so most toddler bed frames will support it.Twin: 38 inches by 75 inchesRoom size requirements: 7 feet by 10 feetThe twin-size mattress is 38 inches x 75 inches—8 inches wider than a crib bed. The twin bed fits children, smaller teens and other single sleepers but isn’t long enough for a full-grown adult. An adult’s feet will hang over the edge, making it harder to get a good night’s sleep.Twin mattresses are compatible with bunk bed dimensions and conserve space for those living in a small apartment or sharing a room.Twin mattresses are easy to move because they are lightweight and small enough to maneuver in narrow hallways.SEE ALSO: Best Mattress for KidsTwin XL: 38 inches by 80 inches longRoom size requirements: 9.6 feet by 10.6 feetThe twin XL size mattress is 5 inches longer than the twin bed, making it best for taller people single sleepers.The twin XL mattress is a popular mattress size for college dorm rooms and pairs well with bunk beds and other single sleepers. Twin XL mattresses aren’t as expensive as full or queen size beds, so keeping one handy a mattress for a guest room is an affordable alternative.Full: 54 inches by 75 inchesRoom size requirements: 9.6 feet by 10.6 feetA full size mattress, or double bed, doesn’t provide enough space for a couple but is a notable upgrade for a single sleeper. A double bed offers enough space to spread out but doesn’t take up much floor space, making it a good option for teenagers or young adults.Double mattresses aren’t as expensive as queen mattresses, but they are a bit harder to move because they aren’t as compact and lightweight as a twin XL.Full XL: 54 inches by 80 inchesRoom size requirements: 9.6 feet by 10.6 feetA full XL mattress has an extra 5 inches of legroom, better suiting the height of a full-grown adult. It’s essentially a queen with a few inches shaved off the sides.We don’t suggest this size for couples because the width is too narrow. However, this bed makes an excellent guest room bed.Queen: 60 inches by 80 inchesRoom size requirements: 10 feet by 10 feetQueen mattresses are the most popular size because they fit in most bedrooms. We suggest this mattress size to couples who don’t need much space or a single adult who needs extra room.The queen size bed is an excellent option for a guest or master bedroom. Many people get queen mattresses for their older teenagers and turn it into a guest bed when the child moves out.Queen size beds come as split queens (two separate mattresses). These work well for couples with different firmness preferences.Olympic Queen: 66 inches by 80 inchesRoom size requirements: 10 feet by 10 feetThe Olympic queen offers 6 additional inches of width for couples who want just a little bit extra room. This mattress isn’t part of the usual size run, so it can be tricky to find along with matching bedding.You can use Olympic queen size mattresses in RVs, campers, and mobile homes.King: 76 inches by 80 inchesRoom size requirements: 12 feet by 12 feetKing mattresses measure 16 inches wider than queen beds, so it provides enough room for two people to have their own space. It’s lengthy enough to accommodate adults of average height, though some over six feet tall may find themselves a little cramped.There is also the split king mattress, which is two twin XL beds side-by-side. This option lets couples choose different firmnesses without compromising on a single mattress. Many people choose this size because it works well with adjustable beds.California King: 72 inches by 84 inchesRoom size requirements: 12 feet by 12 feetCalifornia king mattresses are 4 inches narrower and 4 inches longer than a king mattress. The extra length can accommodate extra tall people. The California king size mattress can comfortably fit two adult sleepers and parents who co-sleep with a child.The California king bed comes in a split option, so each sleeper can select a different mattress firmness from their partner.How to Choose a SizeYou want a bed big enough to encourage restful sleep, so you will need to consider who sleeps in the bed, how much space they need, and your bedroom’s size.Learn more about better sleepSign up for sleep health education, expert tips, and the latest and greatest mattress sales. Email See Privacy PolicyWho Sleeps In the Bed?If you’re buying for yourself, you most likely know what mattress size suits you best; however, if you have a sleeping partner or children you co-sleep with, you have to think about their sleep preferences as well.Mattresses for a couple depend on the two sharing a bed:Full beds don’t offer enough room for a couple to sleep comfortably.Sleeping partners who like to cuddle may enjoy a queen mattress.If you and your partner need space, a king or California king provides it.Meanwhile, single sleeper who enjoys sprawling would fit comfortably on a full. Those who don’t mind a more compact mattress can also enjoy a twin XL mattressRefer to our guide below to find the best mattress size for your circumstances.Toddlers, children, or young teenagers are comfortable on these mattress sizes:Small SingleTwinTwin XLFullSingle adults, college student, or older teenagers are comfortable on these mattress sizes:Twin XLFullQueenTwo adult sleepers are comfortable on these mattress sizes:QueenKingCalifornia KingTwo adult sleepers who co-sleep with children or pets are comfortable on these mattress sizes:KingCalifornia kingYour Body TypeYour height, weight, and body proportions can significantly impact your chosen mattress size. Such as your height may affect the bed size you need to sleep comfortably. For people 5 feet 5 inches or taller, we suggest a mattress at least 80″ long to prevent the feet from dangling over the bed’s edge and disrupting sleep.Here’s how to evaluate your body type and its influence on mattress selection:Height: If you’re taller than average, prioritize a mattress that provides enough length to prevent your feet from dangling off the edge. For individuals taller than 6 feet, a Twin XL, Queen, King, or California King ensures sufficient legroom. For exceptionally tall sleepers, consider oversized options like the Texas King or Alaskan King.Weight and Build: Your weight can determine how much space you need to sleep comfortably. Larger individuals may prefer wider options, like King or California King mattresses, to prevent feeling confined. Additionally, sleepers with broader shoulders or hips may benefit from wider beds to avoid feeling cramped.Proportion and Sleep Style: People who tend to sprawl or sleep in positions requiring more space—such as starfish or combination sleepers—should consider wider beds. If you’re petite or prefer compact sleeping spaces, a Twin XL or Full mattress might be sufficient.Couples and Shared Sleepers: If you’re sharing a bed, ensure the mattress width accommodates both sleepers comfortably. For example, two adults with average builds might find a Queen mattress sufficient, while a King or California King provides more personal space.When assessing your body type, remember that comfort is subjective. Testing mattress sizes—or opting for risk-free trials—can help ensure your choice aligns with your physical needs.Room SizeThe size of your bedroom plays a critical role in determining the right mattress size. Selecting a mattress that’s too large for your room can create a cramped environment, while choosing one that’s too small may leave unused space. Before you buy a bed, consider the surface area of the bedroom the mattress will occupy. A larger mattress needs more surface area space than a small bed. You need to leave enough surface area room for movement between the mattress, the walls, and any furniture.Overcrowding the bedroom surface area can make your sleep environment stressful, which can make it hard to fall asleep. Sometimes you can cheat a little, such as with a Murphy bed mattress that’s put away during the day. Still, make sure to measure your room before deciding on a mattress size.Here’s how to assess your room size for optimal mattress selection:Measure Your Room Dimensions: Start by measuring the length and width of your bedroom. Ensure you account for all walls, doorways, windows, and fixed furniture when determining the available floor space.Leave Room for Movement: A comfortable bedroom layout includes at least 2-3 feet of walking space around the bed. This ensures easy access to other furniture and prevents the room from feeling overcrowded.Consider Furniture Placement: Evaluate the size and placement of existing furniture, such as nightstands, dressers, or wardrobes. Larger mattresses may require rearranging or even downsizing furniture to maintain a functional layout.Accommodate Multi-Use Spaces: For rooms that double as home offices or guest spaces, consider compact options like a Full or Queen mattress. You might also explore Murphy beds or daybeds to maximize space efficiency.Future Considerations: If you plan to move or remodel, consider how the mattress will fit into a new or updated space. A mattress that’s too large may limit flexibility in smaller future bedrooms.Here’s a refresher on room size requirements for mattress sizes:Mattress SizeRoom Size (Inches)Room Size (CM)Crib7 feet by 10 feet213.36 cm by 304.8 cmSmall Single7 feet by 10 feet213.36 cm by 304.8 cmTwin7 feet by 10 feet213.36 cm by 304.8 cmTwin XL9.6 feet by 10.6 feet292.60 cm by 323.08 cmFull9.6 feet by 10.6 feet292.60 cm by 323.08 cmFull XL9.6 feet by 10.6 feet292.60 cm by 323.08 cmQueen10 feet by 10 feet304.8 cm by 304.8 cmOlympic Queen10 feet by 10 feet304.8 cm by 304.8 cmKing12 feet by 12 feet365.76 cm by 365.76 cmCalifornia King12 feet by 12 feet365.76 cm by 365.76 cmThickness Thicker mattresses often provide enhanced comfort by offering more cushioning layers, which can be beneficial for side sleepers who require additional pressure relief at the hips and shoulders. Conversely, back and stomach sleepers might prefer thinner mattresses that offer firmer support.Heavier individuals may find thicker mattresses more suitable, as they offer better support and prevent sagging. Lighter individuals might opt for thinner mattresses to avoid feeling too “sunk in.”The combined height of your mattress and bed frame should be considered, especially for those with limited mobility. A mattress that’s too thick can make getting in and out of bed more challenging. Thicker mattresses can retain more heat, potentially leading to a warmer sleep environment. If temperature control is a concern, consider mattresses with cooling technologies or those made from breathable materials.Your Sleep PositionYour preferred sleep position can give you an idea of how large a sleep surface you need. If you toss and turn a lot or sleep spread-eagle, you’ll need more room than someone who uses a small portion of the bed.Those who need more legroom and restless sleepers should choose a larger mattress; on the other hand, couples who like to snuggle or those who don’t take much space can sleep comfortably on a smaller bed.Back sleepers typically lie in a neutral position, which doesn’t require as much width as other sleep positions. For single back sleepers, a Twin XL or Full mattress can suffice. However, couples who are back sleepers may prefer a Queen or King mattress to ensure adequate space.Side sleepers often need more room to accommodate their position, as legs are often bent or extended to the side. A Twin XL or Full mattress can work for single side sleepers, while couples will benefit from the additional width of a Queen, King, or California King mattress.Stomach sleepers tend to sprawl across the mattress, requiring extra room for their arms and legs. Wider mattresses, such as Queen or King sizes, provide ample space for comfortable movement without feeling restricted.Combination sleepers frequently change positions during the night and need a mattress that allows for freedom of movement. Combination sleepers often benefit from larger mattress sizes like a Full XL, Queen, or King to accommodate their restless nature.Sprawlers and starfish sleepers prefer to sleep spread-eagle or in expansive positions and need more room than average. For single sleepers, a Full or Queen mattress may suffice, while couples should consider a King or California King for optimal comfort.Location of the BedroomThe location of your bedroom can influence your mattress choice. For bedrooms on upper floors or in tight spaces, consider the ease of transporting a larger mattress. Additionally, bedrooms in humid or poorly ventilated areas might benefit from mattresses made with breathable materials to prevent moisture buildup.By accounting for these practical aspects, you can ensure that your mattress fits seamlessly into your home, enhancing both functionality and comfort.Consider Your HomeMattresses are heavy and can get damaged when you’re moving them from place to place. If you plan on buying a large bed, such as a king size mattress or California king size mattress, you might want to wait until you’re settled in your forever home—or a place you are going to live in for at least 10 years.Consider how you’re going to move your mattress. If you’re purchasing a larger mattress, your home might not allow it. Measure doorways and halls so ensure you’ll have enough room to maneuver it.You might consider getting a mattress in a box, which is shipped to your doorstep in a small box—this way, you can easily move the mattress to your bedroom.Larger mattresses can be hard to move through tight spaces; measure hallways and staircases.If you move often, smaller sizes like Twin XL or Full are easier to transport.Ensure you have space to store bedding for larger mattresses.For multi-functional rooms, opt for compact or foldable options like Murphy beds.Check that your mattress size matches your bed frame, especially custom or antique ones.Factor in the cost of larger mattresses, including accessories and transportation.BudgetLarger mattresses contain more materials and, therefore, cost more. If you want a bigger bed, you will need a larger budget. Twin mattresses commonly cost between $300 and $600, and a quality queen size mattress can cost between $700 and $2000.You’ll have to consider the material quality and type of mattress you want to buy, too:Buying a cheap mattress may seem like a good way to save money initially, but you’ll have to replace it more frequently than higher-quality beds, costing you more money in the long run.Some mattress types, like all-latex and hybrid mattresses, cost more than others.Your budget may not only include a new mattress but other items you need to buy, like an adjustable bed.Non-Standard Mattress SizesIf you’re interested in larger or smaller mattresses outside of the usual range, such as oversized family beds or camper mattresses, you may want to look into customizable mattresses. Some mattress manufacturers will take special orders for certain size bed dimensions, along with a shopper’s choice of mattress materials.This is one way to find a mattress that works with an antique bed or that fits into an RV or boat’s sleeping space. Costs can vary when it comes to custom mattresses, but many are quite affordable.A custom-order mattress is one way to get your hands on the biggest possible bed sizes, such as the Texas king, Wyoming king, and Alaskan king. These oversized beds need large bedrooms, but they can easily fit multiple sleepers.The dimensions of some less common types of mattresses are: Super Single: 48 inches by 84 inchesRoom size requirements: 10 feet by 10 feetThe super single mattress is an elongated version of a single bed, offering seven feet of length. While not as wide as a full-size mattress, this extra length makes it ideal for tall sleepers. It is especially for those teenagers or young adults who need space to stretch out but don’t require the width of a full or queen bed. It’s a smart choice for narrow bedrooms where saving space is key.RV Queen: 60 inches by 75 inchesRoom size requirements: 8 feet by 10 feetAn RV queen mattress is slightly shorter than a standard queen-size bed, making it perfect for RVs, campers, and other compact spaces. Its cozy dimensions provide enough room for a couple while leaving space to navigate in tighter quarters. The RV queen is a practical and space-saving solution for mobile homes.RV King: 72 inches by 80 inchesRoom size requirements: 10 feet by 12 feetThe RV King mattress is a scaled-down version of a traditional king-size bed, specifically designed for recreational vehicles and compact spaces. It offers the same luxurious width as a standard king but is slightly shorter to better fit snug RV bedrooms. This mattress provides a perfect blend of comfort and practicality for couples who want the space of a king-sized bed while traveling or living in a mobile home.Texas King: 80 inches by 98 inchesRoom size requirements: 12 feet by 14 feetTrue to its name, the Texas King mattress embodies the saying “everything is bigger in Texas.” At over eight feet long, it’s perfect for sleepers who want ample legroom or for families who co-sleep with children. This size works best in spacious master bedrooms where its impressive dimensions can be showcased without feeling cramped.Wyoming King: 84 inches by 84 inchesRoom size requirements: 12 feet by 12 feetThe Wyoming King offers a perfectly square shape, providing symmetry and style in a contemporary bedroom. Measuring seven feet by seven feet, it delivers an excellent balance of width and length, making it a luxurious choice for couples or families who enjoy spreading out. Its shape fits best in larger, square bedrooms.Alaskan King: 144 inches by 84 inchesRoom size requirements: 16 feet by 16 feetThe Alaskan King is the ultimate mattress for anyone who wants sheer size. At 12 feet wide and 7 feet long, this bed is designed for families, co-sleepers, or those who simply want a centerpiece for their expansive bedroom. It’s the ideal solution for master suites or for creating a luxurious retreat in your home.SEE ALSO: Best Texas King MattressesComparison GuidesIf you find yourself debating two similar sizes, such as full and queen or king and California king size bed dimensions (Cal king), it can help to compare their pros and cons in depth.

Here are some tips to guide your selection:Know Your Mattress Size: Ensure your bedding matches your mattress dimensions precisely. Ill-fitting sheets can bunch up or come loose, disrupting your sleep.Choose the Right Materials: Consider breathable fabrics like cotton or bamboo for a cooler sleep environment. Opt for flannel or microfiber in colder climates for added warmth.Pick the Right Thread Count: A thread count between 200 and 400 typically offers a balance of softness and durability. Higher thread counts may feel luxurious but can trap heat.Invest in a Mattress Protector: A waterproof or hypoallergenic mattress protector can shield your mattress from spills, allergens, and wear.Layer for Comfort: Use mattress toppers or pads to adjust the firmness and add plushness. This is especially useful if your mattress is too firm or old.Match Your Sleeping Style: Side sleepers may prefer softer pillows and bedding for pressure relief, while back or stomach sleepers might need firmer options.Frequently Asked QuestionsWhat’s the difference between a twin and single mattress?Despite the different names, single and twin size mattresses are the same size, both being 38 inches wide x 75 inches long. The name difference started because twin beds were originally sold in a pair, thus the term “twin.” Eventually, brands started selling twin mattresses separately and started calling them “single” mattresses.The term “single” stuck around for a while, but brands started calling single beds “twins” once again, despite there only being one bed of the same size. Nowadays, calling a 38 x 75 inch mattress a “single” is more common in Europe and the UK, while the term “twin” is commonly used in the US and Canada.What mattress size is smaller than a twin?Yes, there is! A crib mattress is smaller than a twin and is designed specifically for infants and toddlers. Crib mattresses typically measure around 28 inches wide by 52 inches long. For slightly older children or small spaces, you might also consider a “narrow twin” or “cot size” mattress, which is narrower than a standard twin but less common. These smaller sizes are perfect for tight spaces or compact beds.What size is a double mattress?A double mattress, also known as a full mattress, typically measures 54 inches wide by 75 inches long. This size offers more sleeping space than a twin but is still compact enough for smaller bedrooms or guest rooms. It’s a popular choice for single sleepers who like extra room or couples who don’t mind sleeping close. Keep in mind that taller individuals may find a full-size mattress too short and might prefer a longer option like a queen.How do you measure a mattress?To measure a mattress, grab a measuring tape and start by checking the length from the head to the foot of the mattress. Then measure the width across the mattress from one side to the other. Finally, measure the depth (or thickness) by checking the height from the base to the top surface. Always take measurements with the mattress lying flat, and don’t forget to include any mattress toppers or pads if they’re a permanent part of your setup.Can I use a mattress topper to make a smaller mattress for two more comfortable?While a mattress topper can provide extra cushioning and support, it may not be the best solution for making a smaller mattress comfortable for two people. Mattress toppers are designed to enhance the comfort of a mattress, but they cannot increase the actual size of the sleeping surface.If a mattress is too small for two people to sleep comfortably, it’s best to consider upgrading to a larger size, such as a queen or king, to ensure both individuals have enough space to rest well.Does size affect how often I need to replace my mattress?Generally, mattresses should be replaced every 7-10 years, depending on factors such as usage, quality, and individual comfort preferences. Mattress size does not directly impact the replacement timeline, as all sizes should be replaced within this general timeframe.However, larger mattresses, such as kings and California kings, may show signs of wear more quickly if they are used by heavier individuals or if the weight is not evenly distributed. It’s crucial to assess your mattress regularly for signs of wear, sagging, or discomfort. Replace it when necessary to ensure you sleep well at night.How do I know if my room is large enough for a king size bed?Consider the bed’s dimensions and how you will set it up in your room. To comfortably fit a king-size bed, there should be sufficient space on either side of the bed for nightstands and room for people to walk around.If you plan on having other furniture, such as dressers or chairs, think about where you’ll place them so the room doesn’t feel too cramped.Are there any benefits to choosing a non-standard mattress size?While these sizes can offer some benefits in specific situations, such as accommodating unique room layouts or individual preferences, there are several drawbacks to consider. Firstly, these mattresses are often more expensive due to their custom nature and limited availability. This can make them a less attractive option for budget-conscious shoppers.Moreover, finding accessories like bed frames, box springs, and bedding for non-standard sizes can be challenging and more costly. Furthermore, if you decide to change your bed frame or move to a new home in the future, a non-standard mattress size may not travel or fit as easily, potentially requiring you to purchase a new mattress altogether.Are there any drawbacks to choosing a larger mattress size?Yes, these mattresses are more expensive than smaller sizes due to the increased materials needed for their construction. Additionally, larger mattresses require more space in the bedroom, which may not be suitable for smaller rooms or apartments.Moving and transporting these mattresses can also be more challenging due to their size and weight, which can be problematic if you relocate frequently or need to navigate narrow hallways or staircases.How do I determine the right mattress size for my child’s room?Think about your child’s age, growth potential, and the available space in the bedroom. For younger children transitioning from a crib, a twin-size mattress is often suitable and can accommodate them for several years.However, if your child is taller or you want a mattress that will last through their teenage years, a twin XL or full-size mattress may be more appropriate. Measure the room and ensure that there is enough space for the mattress and other furniture while allowing for easy movement around the bed.How do I dispose of my old mattress when upgrading to a new size?When purchasing a new mattress, many retailers offer removal and disposal services for your old mattress as part of their delivery process. This is often the most convenient option, as the retailer will take care of the heavy lifting and ensure that your old mattress is disposed of properly.Alternatively, if you prefer to handle it yourself, you can donate your old mattress if it is still in good condition and meets the organization’s donation guidelines. If your mattress is not suitable for donation, check with your local waste management company for recycling and junk pickup options, as some areas require special handling or pickup arrangements for large items like mattresses.Are bed and mattress sizes described differently?Not usually, but there can be slight variations. While bed and mattress sizes are often used interchangeably, there can be differences in specific cases. Standard mattress sizes like twin, queen, and king typically match the corresponding bed frame sizes. However, some bed frames, particularly custom, antique, or adjustable ones, may have unique dimensions or design features that require non-standard mattress sizes. Always measure both the frame and the mattress to ensure compatibility, especially if the frame has extra width, length, or a unique design.Is a double mattress twice as large as a twin mattress?No, a double mattress is not twice the size of a twin. A twin mattress measures 38 inches wide and 75 inches long, while a double (full) mattress is 54 inches wide and 75 inches long. The difference lies in the width; a double mattress provides 16 extra inches of width but does not double the total surface area. It is a more spacious option for solo sleepers but can feel cramped for two adults.Which mattress size is the most popular?The queen mattress is the most popular choice for its versatility. Measuring 60 inches wide and 80 inches long, it provides ample sleeping space for couples while fitting comfortably in most standard bedrooms. Its popularity stems from the balance it offers—large enough to accommodate two people without overwhelming the room. Queen mattresses are also a common choice for solo sleepers who prefer extra space to stretch out and for guest rooms that need to cater to various sleeping arrangements.Does the size of a mattress impact its lifespan?The size of a mattress doesn’t directly determine its lifespan, but larger mattresses like queen or king sizes may experience uneven wear if used by couples who tend to sleep on the same side or area. Regular rotation can help distribute pressure evenly, extending the mattress’s life. Additionally, the longevity of any mattress depends more on factors like material quality, frequency of use, and whether it’s supported by a proper bed frame or foundation that prevents sagging.Do I need to visit a store to determine the right size?No, you don’t need to leave your home to pick out the right mattress size. Instead, you can measure out a rough space and imagine how the mattress would accommodate you. Many online mattress retailers offer detailed size guides, room planners, and customer support to help you buy the right mattress without trying it out in person.Trustworthy retailers also offer risk-free trial periods, allowing you to test the mattress in your home for a specified number of nights before committing to your purchase. This trial period ensures that you have chosen the right size and comfort level for your needs.Can I order a custom-sized mattress?Yes, if you have a unique bed frame or require a specific mattress size, you can reach out to mattress manufacturers or specialty bedding stores to inquire about custom sizing options. Be sure to measure your bed frame carefully, including the interior dimensions and any unique features, such as built-in headboards or footboards, to ensure a proper fit.Keep in mind that custom mattresses may come with a higher price tag and longer lead times compared to standard sizes.ConclusionWhether you sleep alone, with a partner, or co-sleep with children or pets, there is a mattress size that can accommodate your needs. It’s essential to consider not only your personal preferences but also the size of your bedroom and your budget when making a decision.While it may be tempting to opt for a smaller mattress to save space or money, doing so can lead to discomfort and poor sleep quality. On the other hand, selecting a mattress that is too large for your room can create a cramped and cluttered environment, which can also negatively impact your sleep.Taking the time to research and compare different mattress sizes and types can help you make an informed decision that will provide you with the comfort and support you need for years to come. Don’t hesitate to reach out to mattress experts or take advantage of online resources and trial periods to ensure that you find the perfect mattress size for your unique situation.About the author Rosie Osmun CERTIFIED SLEEP COACH Rosie Osmun, a Certified Sleep Science Coach, holds a degree in Political Science and Government from the Arizona State University College of Liberal Arts and Sciences.
