Quilt binding calculator
Find the binding fabric you need for a finished quilt. The calculator uses the quilt perimeter, adds room for corners and joins, and converts it to 2½-inch strips.
Your binding answer

- Strips to cut
- 8
- Binding length
- 290″
- Quilt perimeter
- 280″
How we figured this
- All the way around your 60″ × 80″ quilt is 280″.
- Add 10″ for turning the corners and closing the ends: 280″ + 10″ = 290″ of binding needed.
- Each strip is 42″ long, and every diagonal join uses 2½″ of it. 8 strips cut 2½″ wide, joined 7 times, give 318½″ — enough to go round.
- 20″ of binding fabric in all — ⅝ yard.
Before you cut
Measure the finished quilt top's width and height.
This answer assumes double-fold binding strips cut 2½ inches wide from a 42-inch usable fabric width.
The result adds 10 inches for turning the corners and closing the ends, and counts 2½ inches of length for every diagonal join.
Questions quilters ask
How do I calculate quilt binding yardage?
Add the quilt perimeter and about 10 inches for turning the corners and closing the ends. Each strip gives you the usable fabric width, less one strip width for every diagonal join, so keep adding strips until the joined length covers it. This calculator does those steps for you and shows the working.
What strip width does this binding calculator use?
It uses 2½-inch strips for double-fold binding. If you prefer a narrower or wider binding, use the result as a starting point and adjust your strip width before cutting.
