It is always a big decision when it comes to choosing a new mattress. You certainly don’t want to waste your money on a bed that you might later realize wasn’t the best choice for you.

What size bed should you get? In terms of mattress length, the ideal would be 6 inches longer than your height. As for the width, the mattress should be wide enough for both you and your partner to spread your elbows out and not bump each other.

How to Find the Right Size Mattress

Does it really matter that you pick the right bed size? If quality sleep is what you want, then of course! The best mattress type and the right comfort level can definitely help you have more of a good sleep each night.

In addition, if the size is not right, you might not be able to accommodate other people on your bed when circumstances call for it. You also want a bed that will allow you the freedom to move and flail your arms around comfortably.

In order for you to have this kind of luxury, you need a bed with at least 6 inches longer than your height. So, if you are well above 6 feet, King beds are the ideal size mattress for you. If you know you’ll be sleeping with others, don’t forget to also consider the bed’s width.

Bed sizes from Queens to Alaskan Kings are excellent options if you want wide ones. They are long enough to accommodate the average height and with enough space for at least two people.

Below is a chart of bed sizes to give you an idea of what size might fit you well.

For individuals under 5ft. 5in. tall: Twin (38” W x 74” L)

Although the name says ‘twin’, this size oddly has only enough space for one person. In the UK, it is aptly referred to as a Single with a width suitable for a child or adult that has a height of under 5 feet and 5 inches. In some places, this size is available in 39″ by 75″, so make sure you measure your current mattress or the base of your bed before purchasing.

For individuals up to 6ft. tall: Twin XL (38” W x 80” L)

The Twin XL has the same width as the Twin, but the length is slightly longer. It is six inches longer, which makes it perfect for people of up to 6 feet in height. The Twin XL is 80″ long, which offers a length of 6ft. 6in. That caters to the additional six inches you need so you can comfortably lay down on the bed. While the Twin XL is often available in 38″ in width, you may be able to find some that are 39″ wide.

For individuals under 6ft. tall: Full/Double (54” W x 75” L)

The Full, also known as Double, is a bed size ideal for those under 6 feet tall. It also has an ironic name, even though it’s named Double, it doesn’t offer enough space for sharing. On the other hand, it is ideal for single use. The Linenspa 8-Inch Memory Foam and Innerspring Hybrid Mattress (view on Amazon) is a Full-size bed that’s a great and affordable option for a guest or children’s room.

For individuals who are 6ft. tall: Full XL (54” W x 80” L)

Like the Full/Double, the Full XL is also ideal for single use. However, since it is longer at 80 inches, it can better accommodate much taller individuals. Unfortunately, you won’t find it comfortable sharing the bed, but you can be sure that your legs will have plenty of luxurious space. While the Full-sized bed is mostly ideal for kids, the Full XL is just the right length for adults.

For individuals who are 6ft. tall: Queen (60” W x 80” L)

If you want a Queen bed that can give you plenty of space to sleep, the Sweetnight Queen Mattress (view on Amazon) is a top choice. Queen beds are the solution to have for couples with the partner having around 30” of width without feeling too cramped. As it is 80” long, it easily accommodates people at 6 feet tall.

For individuals who are 6ft. tall: King (76″ W x 80″ L)

The King is the all-time favorite of the various mattress sizes available. Compared to the Queen, the King is 16 inches wider. It is the width that people buy it for, so it means that there is definitely enough space to accommodate two adults. It makes it the recommended choice if you share your bed without sacrificing comfort. The comfortable space it offers is the reason why the King is the most common mattress size people don’t hesitate to get.

For individuals over 6ft. tall: California King (72″ W x 84 “L)

Besides the King, the California King is also one of the most popular bed sizes. It is a favorite of couples throughout the US, given the four inches extra length it provides. With that, people who are over 6 feet tall easily has the necessary six inches for a comfortable bed length. As it is a standard mattress size, you can find them in plenty of stores, online or not. On that note, a popular choice on Amazon for a Cal King mattress is the LUCID 10 Inch Memory Foam Medium Feel – Gel Infusion Mattress (view on Amazon).

Custom Sizes

Kings and California Kings offer well enough spaces for couples whose height is over 6 feet tall. But they may not be spacious enough to some people, though, especially those who have unique sleeping arrangements or behaviors. In that case, you can choose mattresses of custom sizes to accommodate the width and length you need.

  • Wyoming King – The Wyoming King bed is at 7 feet by 7 feet, which is a massive 84 inches by 84 inches. It is wide and long enough for up to 2 adults and with children or multiple pets. As a bonus, it’s also perfect for couples who want a bed that doesn’t produce a lot of sounds or movement, if you see what I’m getting at.
  • Alberta King – The next biggest size is the Alberta King, another custom size at 8 feet by 8 feet. If the Wyoming is not enough, then this one gives you an extra inch of width and length. It is also best for couples who often sleep with their children or pets.
  • Alaskan King – Of all available bed sizes, the biggest is the Alaskan King. It is available in an enormous 9 feet by 9 feet, so big that you need a large bedroom to fit this. If you want the biggest mattress you can find, this is certainly the one. It is, without a doubt, big enough to accommodate people over 6 feet tall.

Where to Shop for a Mattress

When it comes to searching for a great mattress, you don’t just need to consider your height. Several other factors matter too, such as your bedroom space. Also, you must make sure that the mattress you plan on purchasing can fit through your doorways, staircase, and corridors.

Additionally, determine the number of people and pets that will be sleeping on the bed. This will let you know how much room is necessary. When you have all these covered, you can then safely shop around. Below are some tips that can help make the process a little easier and quicker.

In Stores

If you want greater variety, buying from a store is the best option. It will also allow you to inspect the mattress yourself before purchasing. A downside to this is that you might be overwhelmed by the number of options. Our advice is that you take your time and set a certain number of hours to help you process all that you’d see. Take a few minutes to try the mattress and always shop on sales to make the most of them.


Online shopping has become very popular nowadays as it is a convenient way of getting your things without leaving your home. However, you will find fewer options, so it can be a little less overwhelming. Another plus is you don’t have to deal with salesmen whispering behind your ears. Online stores also tend to offer free or discounted shipping and a money-back guarantee, so most of the time it is safe to shop online. The main problem is that you can’t know the feel of the mattress until it is delivered.
