There are six standard mattress sizes in North America: Single, Single XL, Double, Queen, King, and California King. There are also a variety of custom mattress sizes available.

To determine the dimensions of a mattress, measure it from head to foot for the length and from side to side for the width. It may be helpful to measure the depth of the mattress as well, from the bottom where it rests on the box spring to the top.

You will want to use a tape measure and record these three dimensions, in inches, and repeat if necessary if you use a foundation. It’s important to measure your mattress and box spring before buying an encasement or bed.

Now that you know all about the sizes and dimensions of different beds, you should be able to make an informed decision regarding your next mattress. Once you have your sizing figured out, consider an adjustable bed frame for the ultimate comfort or some soft, breathable bedding to outfit your new investment!
