How to choose the right mattress size

There are some key factors to take into consideration before deciding on a mattress size.

How to choose the right mattress size

 

 

You must definitely think of the sleep footprint you will leave. This means considering if the bed will sleep one or two people. And if so, how big or small those bodies are. Here are some tips to remember:

  1. Obviously, you will need a mattress that is at least longer than the tallest person sleeping on it.
  2. An easy way to calculate how much space you will need, is to take note the amount of space you, or you and your partner will take up, and then add some extra space, so that you don’t feel squeezed in the bed or roll off if too close on the edge of the bed.
  3. The bed width should allow sufficient space to fold your arms behind your head without having to touch your partner’s elbows or going beyond the mattress edge.
  4. If you or your partner or both tend to toss and turn a lot during sleep, then you should add even more margin.
  5. Keep in mind that mattress measurements are slightly less than standard bed size, to ensure the mattress fits inside the frame.

Based on the above tips, as a general rule, if only one person will be sleeping in the bed, then a twin, twin XL or full size mattress will work. For two people, a Queen, King or California King bed will give both sleepers ample space, ensuring you receive a good night’s sleep.

The chart below offers a brief overview of all mattress sizes currently available in the market.

TWIN XL, 38”W X 80”L
