How the Quilt Squares and Fabric Calculator works

Squares across = quilt width ÷ finished square size, rounded up, and the same for the length. Each square is cut at finished size + 2 × seam allowance. Squares per strip = usable fabric width ÷ cut size, rounded down. Yardage assumes a single fabric, so divide the squares among fabrics and calculate each one. Add a little extra for mistakes and shrinkage. Example: with Quilt width 60 in, Quilt length 72 in, and Finished square size 6 in, the result is Squares needed = 120; Layout (across × down) = 10 × 12; Fabric needed (yards) = 3.61.
