Quilt Binding Calculator
Enter your finished quilt size and strip width to get the binding yardage. Sashing adds room for the corners and the diagonal join, then counts the strips you cut across the fabric.

In the app, this also gives you
- Bias binding as well as straight
- Checked against your stash yardage
- Your strip width remembered everywhere
How much fabric do I need for quilt binding?
Start with the perimeter of the quilt: two times the width plus two times the length. Add about 10 inches to that so you have enough for turning the corners and for the diagonal join where the two ends of the binding meet. Divide the result by the usable width of fabric, round up, and that is how many strips you cut across the width of the fabric.
The strips are then sewn end to end into one long binding. Cutting across the width of fabric on the straight grain wastes the least, so that is what Sashing counts here. Bias binding uses more fabric but curves around rounded corners, so keep that in mind if your quilt is not square.
Prefer the details? Read how to calculate binding yardage. Once the fabric is cut, how to bind a quilt takes you from strips to a finished edge — joining on the diagonal, mitering the corners, and closing the join invisibly.
There's more where that came from
The app remembers your binding width forever, does bias binding too, and checks the yardage against the fabric already in your stash.
