What are the dimensions of a flat queen-sized sheet?

A typical flat queen-sized sheet measures 90 inches by 102 inches. The accompanying fitted sheet is 60 inches by 80 inches. These fit a standard queen mattress, which is also 60 by 80 inches.

The queen is the best-selling mattress as of 2015. Two adults typically fit comfortably on it, making it a desirable alternative in a space that isn't big enough for a king mattress. A queen bed, however, measures 18 inches smaller than two separate twin mattresses.

Queen mattresses are often selected for small master bedrooms and guest rooms. Many single sleepers who sprawl prefer the extra space. It is also a popular size for tall adults and growing teens.
