Explains How to Measure the Mattress Size

Selecting a Mattress Size

A great deal of care should go into your decision on which mattress size to choose. Mattresses are built to last for many years. That means you want to make sure it fits your needs from day one. How tall you are is going to go far in determining which mattress size is most comfortable for you. You want to make sure that your legs aren’t hanging off the end of the bed. You’ll want extra headroom as well. Sleeping comfortably is the number one purpose of a mattress. You won’t be comfortable if you feel squished into a too-small surface space so this is an important decision.

Mattresses for Couples Sleepers

The common mattress size for couples is 80 inches long and 60 to 76 inches wide. Thus, the mattress sizes queen, king, and California king are good options for couples. The king and queen are more popular for couples since these two usually provide enough space. But the California king size is popular in the United States west coast. It is also 4 inches longer (but 2 inches narrower) than the regular king size. Thus, the California king is a usual choice for taller individuals.

Mattresses for Single Sleepers

The common mattress size for single sleepers is 75 inches long and 38 to 76 inches wide. Thus, the mattress sizes twin, twin XL, and full are good options for single sleepers. A full mattress can still fit a second person, but the twin and twin XL are really for one person only. The full XL is a size that is 80 inches long, so it’s a good option for a taller person, or just someone who enjoys more space.

Mattress Sizes Per Height

We have created a guideline to help you choose the right size mattress for your personal stature. We accounted for the fact you will need a few more inches in addition to your height. Then, we narrowed down the mattress size options per height range. These are simply suggestions meant to point you in the right direction. Keep in mind that you know how much room you like better than anyone else. These are simply a place to start.

8’ 8” or Shorter: Alaskan King Mattress

If you are 8’8” or shorter, an Alaskan King Mattress is a reasonable mattress size.  It is a full 9 feet on both sides, making it long and wide.  More than one person could enjoy sleeping in this mattress.  The tallest consumers would probably prefer it over small mattress sizes.  Its substantial size is desirable and unique.

6′ 8″ or Shorter: California King

For a person whose height is under 6’8”, the California King is an option.  It is seven feet long so accommodating for those who are fairly tall.  If you are right at the edge of this range, you may want to go ahead and upgrade to the Alaskan however.  It will provide the most headroom and legroom.

6′ 3″ or Shorter: King, Queen, Twin XL

All three of these mattress sizes have an 80” length.  They are the most common sizes because many people fit these nicely.  If your height falls around 6’3” or under, you could consider these.  Which you choose would be dictated on other factors-outside of your height.  For example, how many sleepers and the size of each person.

5′ 11″ or Shorter: Twin, Full

The average American is 5’9” according to the CDC.  That means most people will be able to fit on a Twin- or Full-size mattress.  Provided they meet your other sleep criteria, they could be a good fit.  These mattresses are 75” in length with differing widths.  They are some of the most affordable mattress sizes as well.

Mattress Size Factors

Many factors shape your mattress size decision.  These are a few of the things you may want to examine before concluding on the best mattress size for you.

Budget: Smaller mattresses tend to be less expensive than larger ones. Although, mattress type will also play a large role in the cost.

Available Square Footage: Even if you want a massive bed, you will be limited to the size of the bedroom.

Hallway Access: Setting up a mattress is going to require moving into the desired bedroom. Narrow hallways or doorways might cap off the sizes you can choose from.

Age of Sleeper(s): The life of a mattress is several years, so if the user will be experiencing significant growth over the next few years, you may want a mattress that is suitable for the growth.

Who is Using the Mattress: Will the mattress be sleeping one? Two? A couple and a pet or child? These are things to understand and consider as well.

Tall Mattress vs. Short Mattress: Dimensions of the perimeter of a mattress is not the only size to consider.  How tall your mattress is going to be after setup is also a concern.  This mostly impacts the way your mattress looks, but it does somewhat affect functionality.  A box spring makes up around half of the mattress height and platform beds don’t typically use one.  So, a short mattress may not be ideal for a platform bed.  Additionally, if a mattress is too tall, it may hide the headboard once decorative pillows are added.

Headboard Calculations: Though a headboard can be purely ornamental, often times, it is used as a chairback of sorts.  People can lean on the headboard as they read or watch television.  If the mattress height is too tall, there may not be enough of the headboard usable for this purpose.  To ensure the mattress you choose is the right size in this regards you’ll need to do two things.  First figure out what the measurement will be from the top of the mattress to the top of the headboard.  Compare it to your body- waist to head measurement.  A good rule of thumb is the first measurement should be approximately four inches longer.
