How we worked it out
Updated as you change the numbers.
- Perimeter = 2 × (60 + 72) = 264 in, + 10 in extra = 274 in.
- Strips = 274 ÷ 40 in = 6.85, rounded up to 7.
- Fabric = 7 × 2.5 in = 17.5 in ÷ 36 = 0.486 yd, so buy 1/2 yd.
Method and assumptions
Binding goes once around the quilt, plus extra for the mitered corners and the final join. Strips are cut across the width of the fabric and joined end to end; the fabric needed is the number of strips times the strip width, rounded up to the nearest eighth of a yard.
Tips
- Join strips with diagonal seams so the bulk spreads out.
- Bias binding, for curved edges, takes more fabric; this calculator is for straight-grain strips.
