Q: How much binding for a throw quilt?

A 50 x 65 in throw quilt needs 240 in of binding: 6 strips cut across 42 in fabric. At 2 1/2 in wide that is 1/2 yd of fabric; at 2 1/4 in wide it is 3/8 yd.

Throws are the most common first quilt. At 50 x 65 in they are big enough for the sofa and quick to finish.

6 strips, 240 in of binding.

1/2 yd at 2 1/2 in wide · 3/8 yd at 2 1/4 in wide.

How it's worked out

Quilt size: 50 x 65 in, which is a typical 50 x 65 in throw (sizes vary by pattern).
Binding length = 2 x (50 + 65) + 10 in for joins and corners = 240 in.
Strips = 240 ÷ 42 in usable width = 5.71, rounded up to 6.
Fabric = 6 x 2 1/2 in = 15 in, rounded up to the next 1/8 yd = 1/2 yd (or 6 x 2 1/4 in = 13 1/2 in = 3/8 yd).
