Learn more Updated September 7, 2021Potential shoppers should consider size when looking for the best mattress—room dimensions and who the bed is meant for are significant factors in finding the right mattress for the bedroom. Two sizes in particular—queen and twin XL—differ significantly in size and versatility. A queen size is better for single adults and couples, while a twin XL is better suited to the single person.What’s a Queen Size Mattress?A queen size mattress is the most popular mattress size because of its versatility. At 60 inches by 80 inches, queen size beds provide extra sleeping space and more legroom for single adults and are a great mattress for couples with tight budgets or limited living space. Queen mattresses are also excellent options for guest bedrooms since they can accommodate one or two sleepers.VariationsThe standard queen size is also available in Olympic queen and split queen variations.Olympic Queen MattressA variation of the queen bed is the Olympic queen, measuring 66 inches by 80 inches. The extra width provides more room for couples and luxurious space for solo sleepers. Olympic queen beds are typically found in RVs and trailers.Split Queen MattressThough not as available as split king, split queen mattresses are two separate beds put together. Each bed provides 30 inches of personal space, not as much room as a split king, but couples with smaller bedrooms may prefer this mattress size.PricingThe cost for a queen size mattress ranges between $500 to $3000. Potential shoppers can expect to pay more for natural, organic materials and sleep technologies, like a zoned support system.Recommended Room SpaceQueen size beds are excellent additions to master bedrooms and guest rooms measuring at least 10 feet by 10 feet. This room size allows for a bed frame, furniture, like nightstands, and walking space.ProsBest for single sleepersGood for couplesExtra spaceConsMore expensive than a twin XLHeavier, more difficult to moveWhat’s a Twin XL Size Mattress?A twin XL size mattress is similar to a standard twin but gives 5 inches of extra length for more leg space—the perfect size for tall people. Twin XL beds are small and compact—measuring 38 inches by 80 inches—easy to move and fit in most small bedrooms. Twin XL beds are also standard in college dorm rooms, making them ideal mattresses for teenagers and single adults.Twin XL size beds are perfect sleeping options for children too big for a crib mattress. Their small size accommodates growing children and fit bunk beds.PricingThe cost for a twin XL size mattress is about the same for a twin, varying between $100 on the low-end and $2000 on the high end. Price depends on the mattress thickness and the number of layers the mattress contains (more material, higher price tag). The price is also affected by special features, like cooling technologies.Recommended Room SpaceThe best room size for a twin XL mattress should measure 7 feet by 10 feet to accommodate additional furniture, like a nightstand and dresser, and provide walking space. For families with more than one child, bunk beds are an excellent option, utilizing limited space.ProsBudget-friendly mattress optionFits most bedroomsPerfect for children’s roomConsToo small for couplesOther Mattress DimensionsIf a queen or twin XL is not the right size for you, other mattress sizes are available, including twin, full, king, and California king.Twin MattressTwin size mattresses are 38 inches by 75 inches. Their small, compact size makes them easy to move and a good fit for most bedrooms. Plus, since they’re smaller in size, they’re more affordable. Twin beds are an excellent choice for children and single adults—both twin XL and twin mattresses are also compatible with bunk bed frames.Full MattressFull size mattresses (also known as double beds), measure 54 inches by 75 inches. Full beds used to be the most popular mattress for couples in the 60s, but since the rise of queen mattresses, full mattresses are now considered better for solo sleepers. Full size beds are best for teenagers and single adults.Full XL MattressFull XL mattresses are 5 inches longer, measuring at 54 inches by 80 inches. Full XL beds are great for tall, single sleepers—the extra long mattress gives more legroom for tall sleepers to stretch out.King MattressKing size mattresses are 76 inches by 80 inches—the largest standard size available. King size beds are best for couples, providing 38 inches of personal space. Due to their large size, king beds are more expensive, difficult to move, and may only fit inside large master bedrooms.Split King MattressMany couples prefer a split king over a standard king because the split king option is the equivalent of two twin XL mattresses placed side by side. Couples can have a bed suited to their personal preferences without having to compromise. Plus, if paired with an adjustable base, couples can also have the added benefit of elevating their head and feet without disturbing their sleep partner.California King MattressCalifornia king size mattresses are 72 inches by 84 inches—similar to a standard king size, but longer and narrower, making a Cal king bed perfect for tall couples. A California king bed offers 36 inches of personal space to each person, less than a king size but providing more legroom.Split California King MattressSplit California king mattresses are two separate beds placed side by side, giving 36 inches of personal space to each sleeper. For luxurious comfort, add an adjustable bed frame—each person can elevate their head or feet without disturbing the other sleeper. A split California king mattress is not as accessible as a standard California king bed.Other Things to ConsiderHow much bigger is a queen than a twin XL?A queen mattress is 60 inches by 80 inches, while a twin XL bed is 38 inches by 80 inches. A queen size bed provides 22 inches more width than a twin XL. This makes it the perfect option for single sleepers looking for more luxury sleeping space, or couples on a budget.Is a 6-inch mattress thick enough?Mattresses thinner than 8 inches won’t provide the right amount of support because of the layers they lack. Thicker mattresses will offer better support, especially for plus-size sleepers and stomach sleepers who need a firmer surface for better support. Thinner mattresses are also more likely to wear down prematurely.Do two twin XL beds make a California king?No, two twin XL mattresses do not make a California king bed. Half of a California king mattress does not equal any standard mattress size. However, two twin XL mattresses side by side are the same size as a regular king mattress.Can I put a twin XL mattress on a twin frame?A twin XL mattress’s extra 5 inches will prevent it from fitting into a twin size frame. Even if the material is flexible enough to squeeze in, doing so will likely damage the mattress.Similarly, twin size sheets won’t fit a twin XL mattress. However, you might be able to use twin XL bedding with a twin size mattress, although the fitted sheets may bag a bit.Is a split king bigger than a king?No, a split king bed is the same size as king mattress. The difference between the two is that a split king is divided into two mattresses, while the king mattress remains whole. A split king is an excellent option for couples who don’t share comfort preferences or plan on using an adjustable bed.ConclusionQueen and twin XL mattresses are excellent choices for any sleeper. Twin XL beds are the preferred choice for children and single adults; queen size mattresses are popular among single sleepers and couples. The mattress size you choose should be based on room dimensions and who the bed is for, making sure it gives enough space for a comfortable night’s rest.About the author Malik Karman“Professional sleeper” Malik Karman is a freelance writer for the eachnight blog.
