How the calculation works
The required binding length is the quilt perimeter plus the extra length you enter. Strips are cut across the usable fabric width. Diagonal joins consume one strip-width at each connection, so the total length of the strips before joining is not the finished binding length.
The default extra length is 254 mm and the default selvage loss is 25 mm; both are editable. This tool estimates straight-grain strips with diagonal joins, not a continuous bias-binding layout.
