Calculate how much binding fabric you need for your quilt. Includes standard size presets and supports both double-fold and single-fold binding.
Quilt Binding Calculator
Calculate binding strip length and fabric requirements for your quilt
Formula
Binding Length = 2 × (Width + Height) + ExtraPerimeter plus extra for joining strips and mitering corners

* Binding estimates based on 2.5" strips from 42" wide fabric
Binding Tips
Joining Strips
Join binding strips at a 45° angle to reduce bulk. This diagonal seam distributes the thickness more evenly around your quilt.
Mitered Corners
Stop stitching 1/4" from each corner, fold the binding up at 45°, then fold back down to create a neat mitered corner.
Finishing
Leave about 10" unsewn at the start. When you reach the end, join the binding ends with a diagonal seam for a seamless finish.

Frequently Asked Questions
What's the difference between double-fold and single-fold binding?
Double-fold (French) binding is folded in half lengthwise before attaching, creating a more durable edge. Single-fold binding uses less fabric but is less sturdy.
Why do I need extra binding length?
Extra length (typically 10-12") accounts for joining strips together, mitering corners, and finishing the binding ends.
What width should I cut my binding strips?
For double-fold binding, 2.5" is standard (finishes to about 5/8"). For single-fold, 2" is common. Adjust based on your preference.
Should I cut binding on the bias?
Bias binding is recommended for quilts with curved edges. For straight edges, straight-grain binding works well and uses less fabric.
