Quilt Binding Calculator
Almost done with your quilt? This calculator figures out exactly how much binding fabric you need. Enter your quilt dimensions, choose your strip width, and get the number of strips to cut plus the total fabric yardage to buy.
The binding calculation follows these steps:
- Perimeter = 2 x (Length + Width)
- Total binding = Perimeter + extra for joins and corners (usually 10-12")
- Strips needed = Total binding / Usable fabric width (WOF)
- Fabric yardage = Strips needed x Strip width / 36
Common Quilt Sizes
| Size | Dimensions | Perimeter |
|---|---|---|
| Baby | 36" x 52" | 176" |
| Throw | 55" x 65" | 240" |
| Twin | 68" x 86" | 308" |
| Queen | 86" x 96" | 364" |
| King | 105" x 96" | 402" |
Binding Tips
- 2.5" strips are the most popular width for double-fold binding
- Straight grain works for straight edges; bias is needed for curved edges
- Join strips at 45-degree angles for less bulk and a cleaner finish
- Always buy a little extra fabric to account for cutting mistakes
