How the Quilt Binding Calculator works
Binding length = quilt perimeter + extra for mitred corners and joining the strips. Strips = length ÷ usable fabric width, rounded up. Fabric = strips × strip width ÷ 36. Common cut widths are 2.25 to 2.5 inches for double-fold binding. Example: with Quilt width 60 in, Quilt length 72 in, and Cut strip width 2.5 in, the result is Binding length needed (in) = 276; Strips to cut = 7; Fabric needed (yards) = 0.49.
