How many 6.5-inch squares are needed to make a queen-size quilt?

A standard queen-size quilt is 90 inches by 94 inches, so it requires 210 6.5-inch squares. This answer assumes the squares are 6.5 inches on each side after they are sewn together.

The calculation is as follows: 90 inches divided by 6.5 inches equals 14 squares. This figure is rounded up because there cannot be a partial square at the end. 94 inches divided by 6.5 equals 15 squares. Fourteen squares times 15 squares equals 210 squares. If the squares start at 6.5 inches and become smaller after they are sewn together, use the same calculation, substituting the true measurement for 6.5 inches.
