Quilt Binding Strip Estimator

Estimate strip count and fabric yardage from quilt perimeter and strip width.

What this result means

The tool adds the quilt perimeter and your overlap allowance, divides by usable fabric width for strip count, and converts the total cut-strip width to yardage. The result is intentionally labeled as an estimate because a number can be mathematically correct while the input, unit, rule, product, or real-world application is wrong. Keep the entries with the result so another person can reproduce it.

How to use the calculator

1. Read every label and unit before entering a value.
2. Measure the final item, area, time window, or inventory—not a memory of it.
3. Enter the values and save a screenshot or written note of the assumptions.
4. Compare the result with the controlling current source.
5. Add a practical buffer only when the method and situation support one.

Worked example

Straight-grain binding uses different planning than bias binding. Curves, scallops, pattern matching, and preferred joins require a different allowance. Change one value at a time to see which assumption has the greatest effect. Do not round until the end unless the current rule says otherwise.
