Standard Mattress Dimensions

Knowing standard mattress sizes will help you design and make a quilt that fits a bed just right.  The dimensions below are the actual mattress dimensions, not the quilt size.

Mattress Depths

There are no standard mattress depths. Some mattresses are 9-10 inches deep, but many pillow top mattresses measure 15-16 inches in depth, or even more. Box springs and other bed components can make the mattress even higher.

If you're making a quilt for yourself it's much easier to consider all the bed size "what ifs." If the quilt is a gift, you can't even be sure which bed size it will ultimately be used on. When you aren't sure, consider making a quilt that would fit a queen mattress, the most popular bed size.
