Quilt binding calculator
Questions
How many binding strips do I need?
Add up all four sides of the quilt, add 12" for corners and joining, and divide by the usable width of your fabric (about 40"). Round up.
How do I join binding strips?
Join strips with a diagonal seam at a 45° angle to spread the bulk, trim to ¼", and press the seam open.
What about bias binding?
Bias binding is needed for curved edges and uses more fabric. This calculator is for straight-grain strips cut across the width of fabric.
