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.
