Mattress Sizes and Dimensions

Finding the Right Mattress Size

Not sure what size mattress is right for you? Purchasing a new mattress is a big investment, so you’ll want to make sure your choice for mattress size takes all of your needs into consideration.

For example, how will the size of your mattress work with the square footage of your bedroom and your overall interior design plan? Do you need a mattress that comfortably sleeps two, or are you planning on sleeping solo on it?

Once you know what your needs are regarding your decor and sleeping arrangement, you can start to consider what mattress sizes will work best for you. Let’s explore the dimensions of the various standard options on the market.

Mattress Size Chart

 

There are more mattress sizes out there than you might think. You should take a few specs into consideration when looking at each mattress size, including your height, weight, the number of sleepers planning to use the bed, and the overall dimensions of the mattress.

The height accomodation is calculated with the parameter that the tallest person sleeping in the bed should have at least six inches of extra height space. That being said, many adults who are under five feet nine inches, for example, will still feel slightly cramped on a twin or full size mattress even though they will have six inches to spare. This truly comes down to personal preference.

Mattress weight limits vary widely depending on the materials used. For example, many memory foam based mattresses have no weight limit. If you are on the heavier side and want to make sure your new mattress will support you well, check on the mattress brand’s website to see what their specifications are.   Let’s take a look at the weight limits of a few popular direct to consumer mattress options:

 

  • Purple mattress: 120 – 300 lbs. per person
  • Tuft & Needle mattress: up to 500 lbs. per person
  • Saatva mattress: up to 300 lbs. per person
  • Nectar mattress: up to 325 lbs. per person
  • Avocado mattress: up to 350 lbs. per person

Twin

Twin beds are the smallest common size of mattress. They are generally used for kids’ and adolescents’ rooms and are not large enough to sleep most adults very comfortably.

Twin XL

Twin XL beds are often referred to as dorm mattresses. They make more room for a fully grown adult, whereas a regular twin can be a crunch for anyone particularly tall.

Full/Double

Full sized beds, also called double beds, are common choices for guest rooms and teen rooms. They also work well for single people who want to use their living space as efficiently as possible and don’t mind having a smaller sleeping surface.

Full XL

The full XL mattress size is definitely only going to sleep one person comfortably, but it caters to someone a bit taller than would be comfortable on a regular full or double sized bed.

Queen

A queen size bed is a go-to choice for many single sleepers who want a bit of extra space or the option of sleeping two if necessary. Queen sized beds can also work great for couples who tend to sleep close to their partner and don’t mind not having a ton of personal space.

Olympic Queen

Olympic queens are not a very common size of mattress, but you do see them occasionally. They are the same length as a regular queen mattress, but they offer an extra six inches of lateral room, making them a good choice for couples with smaller bedrooms who want a little more sleeping real estate than they can get from a regular queen.

King

A king sized bed is great for couples who want a little extra wiggle room and have the bedroom dimensions to accommodate a large piece of furniture. This size bed is also helpful if you tend to move around a lot in the night and don’t want to disturb your partner by bumping into them.

California King

For those who really want some extra space, the California king size offers plenty of room to spread out. This is the largest style of mattress you’ll commonly see on the market. In many cases, a California king mattress will cost the same amount as a regular king mattress of the same model. California kings are slightly taller and slightly narrower than king size beds.

Crib Mattress

Crib mattresses for small children and babies vary by size, but 27 by 52 inches is a standard range for a crib bed. Mattresses of this size are generally used by little ones until around their second or third birthday, when many parents opt for a twin size mattress.
