Result summary
Quick answer
With the sample inputs, this calculator returns 9 strips binding strips. Quilt perimeter: 324 inches. Use 9 strips binding strips as the yardage or strip-count starting point, then check usable width, seams, pattern repeat, shrinkage, cutting layout, and the increment in which the fabric is sold.
Instructions
How to use this calculator
Open the short walkthrough for choosing and checking inputs.
The calculator finds quilt perimeter, adds joining and finishing overlap plus a cutting allowance, divides by usable width for strip count, and converts strip width to yardage.

Calculation details
Formula and methodology
See the exact math used to produce the result.
Binding length = quilt perimeter + finishing overlap, adjusted by the cutting allowance; strip count divides that length by usable fabric width and rounds up.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are Quilt length, Quilt width, Cut strip width, Usable fabric width, Joining and finishing overlap and cutting allowance. Strip count assumes straight-grain width-of-fabric strips and includes the entered overlap; bias binding, curved edges, flange binding, joining angles, mitered corners, narrow usable width, shrinkage, and a spare strip can increase the purchase.

When to round up
Round up for bias joins, mitered corners, test strips, narrow usable width, directional fabric, shrinkage, scrappy binding, or a flange that changes cut width.
When to use this calculator
- Turning finished project dimensions into a fabric purchase estimate
- Comparing usable width, seams, fullness, overhang, and pattern-repeat layouts
- Checking yardage before buying, prewashing, or cutting fabric
Tips for better estimates
- Use the measured width between selvages rather than the nominal bolt width.
- Keep grain, nap, one-way prints, repeat matching, seams, and shrinkage visible in the cutting plan.
- Round to the seller's increment only after checking the layout and adding a project-appropriate reserve.
How this estimate was built
This page calculates quilt perimeter, adds joining and finishing overlap, applies the cutting allowance, rounds full-width strip count up, and converts the strip count and cut width to fabric yardage.
Worked example
Example inputs: Quilt length: 90 inches; Quilt width: 72 inches; Cut strip width: 2.5 inches; Usable fabric width: 44 inches; Joining and finishing overlap: 12 inches; Cutting allowance: 10 %. With those values, the calculator returns 9 strips binding strips. Cut about 9 strips across the usable fabric width for the entered quilt and allowance.
Example scenarios
- A 72-by-90-inch quilt has a 324-inch perimeter before binding overlap or cutting allowance.
- Adding 12 inches for joining and finishing plus 10% allowance produces about 369.6 inches of binding length.
- At 44 inches of usable width, the sample requires nine full-width 2.5-inch strips, or about 0.63 yard before store-unit rounding.
Quick reference chart
| Sample result | 9 strips binding strips |
|---|---|
| Quilt perimeter | 324 inches |
| Binding length with allowance | 369.6 inches |
| Full-width strips | 9 strips |
| Fabric yardage for strips | 0.63 yards |
| Best next step | Use 9 strips binding strips as a starting estimate, then compare it with the real conditions before acting. |
FAQs
Quilt Binding Calculator questions
Can I use this as my final fabric order?
Use it as a planning estimate, then confirm usable width, grain, direction, seams, repeat matching, shrinkage, cutting layout, and the pattern instructions.
Should I add extra fabric?
Usually yes. Add a project-appropriate reserve for shrinkage, defects, matching, test cuts, damage, and future repairs.
What fabric width should I use?
Use the measured usable width between selvages, not only the nominal width printed on the bolt.
Can the calculator optimize irregular pattern pieces?
No. Sketch the cutting layout and follow the pattern instructions for garments, bias cuts, fussy cutting, borders, and other irregular pieces.
Is the quilt binding calculator exact?
No. It is a fabric-planning estimate. Usable width, shrinkage, nap, pattern direction, matching, seams, and the actual cutting layout can change yardage.
What inputs matter most?
Quilt dimensions, binding strip width, usable fabric width, overlap, and cutting allowance determine strip count and yardage.

Common planning mistakes
Using nominal instead of usable fabric width, rotating directional pieces, forgetting seams or shrinkage, ignoring repeat matching, and rounding before checking the cutting layout.
