How much binding for a 36 × 36 quilt?
Baby size quilt, finished 36″ × 36″.
Buy
3/8 yd
Cut 5 strips 2½″ wide across the width of fabric for 156″ of double-fold binding. Metric: 0.4 m.
How it's worked out
- Perimeter: (36 + 36) × 2 = 144″.
- Add about 12″ to join the ends and turn the corners: 156″.
- Each strip across 42″–44″ fabric gives about 40″ usable, minus ~2½″ for each diagonal join → 37½″ per strip.
- 156 ÷ 37½ = 4.16 → 5 strips. 5 × 2½″ = 12 1/2″ → round up to 3/8 yd.
Binding by strip width
| Strip width | Strips | Buy | Metric | Bias (continuous) |
|---|---|---|---|---|
| 2″ | 5 | 3/8 yd | 0.3 m | 19 3/4″ square (5/8 yd) |
| 2 1/4″ | 5 | 3/8 yd | 0.3 m | 21″ square (5/8 yd) |
| 2 1/2″ | 5 | 3/8 yd | 0.4 m | 22 1/4″ square (5/8 yd) |
| 3″ | 5 | 1/2 yd | 0.4 m | 24 3/4″ square (3/4 yd) |
Bias binding is only needed for curved or scalloped edges; straight-grain strips are fine for square corners.
