How this was calculated
This is an estimate. Measure your quilt and fabric before you cut.
Allowances vary by quilter and machine. Change any value to match yours.

How the amount is worked out
Go once around the quilt, then add 20 inches for joins and corners. Divide that by the usable fabric width and round up, because you cut whole strips. Strips times strip width is the fabric, rounded up to the step you buy in.
Example: a 60 by 72 inch quilt is 264 inches around, 284 with the extra. At 40 inches of usable width that is 8 strips. Cut 2½ inches wide they take 20 inches, so buy ¾ yard.
Choosing a strip width
Common widths are 2, 2¼, 2½ and 3 inches. A wider strip keeps the same number of strips and takes more fabric. Tap a width or type your own.
Questions
How wide should binding strips be?
2½ inches is our starting value. You can choose 2, 2¼ or 3 inches, or type your own.
How much extra length do I need?
We add 20 inches for joins and corners. You can change it.
Why is the answer rounded up?
You can't buy a part of a step at the cutting table, so yardage goes up to the next step you choose.
