If you pick the wrong bed mattress sizes you will not only end up spending a significant amount of money but will also have to go through the grind of returning it. So it's imperative to pick correctly the first time around. You don't want to be the one who purchased a double for your couple without realizing that bed only offers the width size of a crib for each person.

(Buying from links on this website sometimes adds a bit of cash to my lumpy mattress fund. It doesn't cost you more. And helps me spread sweet dreams everywhere.)

Look at the list below and the table afterwards to help you determine the mattress size that you should pick:

Mattress size picking checklist

  • How many people who will sleep on the mattress?
  • What are your weights and heights
  • How big is your bedroom
  • What type of bed frame do you have (if any)?
  • Any other bedroom furniture?

This is one of the basic mattress size charts that depict the length and width in both inches and centimeters. You can opt for these sizes even when buying a memory foam mattress.

Choosing The Right Mattress Size

  • While looking at the different mattress size charts ensure that the length of the mattress should be 6 inches more than the height of the person who intends to use the bed.
  • The next constraint should be the width, unfortunately you cannot use mattress size charts to determine if the width of the bed is comfortable; for this you will need to try out various bed mattress sizes by lying on them comfortably with a pillow below your head. Now put your hands behind your head and see if your elbows go beyond the mattress if you are shopping for one person or if it touches the elbow of the other person when picking a mattress for two people.
  • The size of the room will also be a factor; after all, you don't want to bump into the furniture every time you try to get into bed so leave a clearance of at lease 22 inches on all sides of the mattress
  • If you are shopping for kids or teenagers remember that they are going to grow, so purchasing cheaper small bed mattress sizes today will just pave the way for extra expenditure to buy a larger mattress in a few years or even months.
