Biggest Bed Size: Wyoming King, Texas King, and More

The standard king size bed (the largest standard mattress size) is 76 inches wide and 80 inches long. This sounds big already, but the bigger bed sizes are several inches to several feet bigger than the regular king size mattress.

To many of us, oversized mattresses seem absolutely unnecessary, but they do have their perks. Most people use oversized mattresses because the beds accommodate large families. Others turn to oversized mattresses if they’re uniquely tall.

The exact big bed you may want varies on how you plan on using it. For co-sleepers, it depends on how many people are in your family. Tall sleepers should look at how tall they are compared to the bed’s length to help them decide.

Below, we take you through the three bigger bed sizes and where you can find them if you’re interested.

Biggest Bed Size Mattress Dimensions

Wyoming King

Dimensions: 84 inches wide by 84 inches long

It’s almost funny calling a Wyoming king small, but of the three biggest bed sizes, the Wyoming king mattress is the smallest. It’s 84 inches wide by 84 inches long, making it 4 inches longer and 8 inches wider than standard king size bed dimensions.

You might see some companies calling a mattress of this size an emperor size mattress, but it’s the same as a Wyoming king mattress.

Wyoming kings are a good option for plus-sized couples or families who want to co-sleep with one or two children. The Wyoming king bed isn’t unreasonably large, either, so you can use it in most rooms where you would use a standard king bed (roughly a 12 by 12 foot room).

Due to their size and the number of materials needed for their construction, Wyoming king mattresses typically cost between $1500 and $3000, making many of them one of the best mattresses under $2000.

Pros

• Suitable for tall single adults and an excellent mattress for couples
• Fits large sleepers or couples
• Good for small co-sleeping families

Cons

• More expensive than large standard size mattresses

Texas King

Dimensions of the Texas King: 80 inches wide by 98 inches long

The Texas king mattress is the second largest oversized mattress, named after the second-largest American state. The Texas king is 80 inches wide and 98 inches long, so while the Texas king mattress is narrower than the Wyoming king, the Texas king is also 14 inches longer.

Texas king mattresses are a good mattress for tall sleepers if a king or California king bed just isn’t cutting it. And when we mean tall, we mean someone who is at least 6.5 to 7 feet tall can easily sleep in a Texas king mattress. Even then, someone who is 6.5 feet tall (78 inches) would still have 20 inches of extra foot room.

A Texas king is just a bit more than Wyoming kings, costing between $2000 to $3500 on average. A Texas king fits in narrower bedrooms, but your room should be at least 12 feet wide by 14 feet long to fit this bed.

Pros

• Accommodates very tall single sleepers
• Good for families who don’t have wide bedrooms

Cons

• Narrowest oversized mattress
• Doesn’t fit more than one or two small children for co-sleep

Alaskan King

Dimensions of the Alaskan king: 108 inches wide by 108 inches long

Since Alaska is the largest state in America, it’s only fair to call the Alaskan King size mattress the largest oversized mattress after it. The Alaskan king is 108 by 108 inches, which is ginormous compared to other large mattresses.

The Alaskan king bed is 24 inches longer than the California king mattress, the longest standard mattress, and the Alaskan king is 32 inches wider than the king, the widest standard mattress. To put this into perspective, that’s several feet of extra space for the Alaskan king on both ends of the bed to make it an Alaskan king.

Alaskan king mattresses are a great option for very tall adults who need to stretch out since there will be no chance of their feet sticking out. An Alaskan king size mattress is also an excellent family bed for those who want to co-sleep with more than two children.

The Alaskan king size mattress even fits up to three or four adults comfortably, if you’re ever in a pinch and need to share a large bed, the Alaskan king is what you want.

Since the Alaskan king is so large, they cost between $2500 to $5000 for the mattress alone. Your bedroom should be at least 16 by 16 feet to fit an Alaskan king, though most master bedrooms are smaller than this.

Pros

• Perfect for large, co-sleeping families
• Suits very tall sleepers
• Couples won’t disturb each other while sleeping

Cons

• The most expensive oversized mattress
• Requires a huge master bedroom

Where to Get Oversized Mattresses and Accessories

Your everyday mattress store won’t sell oversized mattresses or their accessories (bed frames, foundations, sheets, or comforters). You can usually find this large of mattresses at specialty retailers or boutiques that make each bed to order. The companies who sell oversized mattresses typically sell the matching accessories as well.

With custom-ordering, you can generally decide what the mattress is made from and can choose to add any special materials. You might consider a hybrid, innerspring, or memory foam mattress.

Since oversized mattresses are so large and uncommon, the price tags are quite hefty, from between $1500 to over $5000. Choosing a customizable mattress with special materials, like organic textile and foams, can cause the final cost to significantly climb.

Before getting any oversized mattress, be sure you have a big enough bedroom to accommodate it. Ideally, there should be at least 2 feet of space between three sides of the bed, excluding the side against the wall, to account for walking space and any other furniture in the room.

FAQs

What are the standard mattress sizes?

There are six standard mattress sizes, with the smallest being a twin bed and the largest being a king bed. The standard bed sizes are as follows:

• Twin: 39 x 75 inches
• Twin XL: 39 x 80 inches
• Full/Double: 54 x 75 inches
• Queen: 60 x 80 inches
• King: 76 x 80 inches
• California King: 72 x 84 inches

Some non-standard sizes you might come across include crib, toddler, small single (cot), full XL, and Olympic queen size mattresses.

What’s a double king size bed?

A double king size bed is the widest oversized mattress at 152 inches wide and 80 inches long. That’s the equivalent of four twin XL beds pushed together.

At 12 feet wide, this bed is absolutely massive and will likely fill the length of most bedrooms, if not more. A double king bed is good for co-sleeping families with three or four children.

Is co-sleeping okay?

Many families are intrigued by oversized mattresses to co-sleep. Co-sleeping, also called bed-sharing, is when parents sleep in bed with their children or infants.

In the past, sharing a large bed with your children was common, but nowadays, most families sleep separately. Still, some families have returned to co-sleeping to better bond with their children. However, co-sleeping does raise your child’s risk of sudden infant death syndrome (SIDS) and should be done with caution.

What mattress size is good for couples?

We recommend using at least standard queen beds or standard king beds if you share your bed, though a queen size mattress is the smallest comfortable option. If you and your partner are moderately tall (between 6 to 6.5 feet), a California king size mattress or Wyoming king offers extra foot room.

We recommend Alaskan or Texas kings for plus-sized couples and couples who co-sleep with their children. You may also consider one of these two mattresses if you and your partner have different sleep schedules because there will be minimal motion transfer from one end of the bed to the other.

What size bed should a 6-foot tall person get?

With the mention of how oversized beds are suitable for incredibly tall individuals, you may wonder what type of bed an average-height adult needs. Those who are roughly 6 feet tall should use a bed 80″ or longer. Twin XL, queen, king, and California king mattresses are all suitable standard size mattresses 80″ or longer.

Small single bed sizes like twin XL mattresses are suitable for dorm rooms, bunk beds, and small homes, while the larger mattress sizes fit best in master bedrooms or as mattresses for guest rooms.

Conclusion

Frankly, most people won’t need an oversized mattress, but if you’re in a large co-sleeping family or are very tall, investing in a big bed might be a smart move. The main factor to keep in mind when choosing one of the bigger bed sizes is to have enough space in your bedroom. They’re also quite heavy and difficult to transport, so once it’s in your home, it may be a big task to get it out.
