Calculate fabric yardage and strip count for quilt borders. Enter quilt dimensions and up to 5 border widths to get exact yardage for each border.
How to Use the Border Calculator
Enter your finished quilt dimensions (before adding borders), select 1–5 borders, then enter each border's finished width. The calculator uses 40" usable fabric width by default — update this if your fabric is wider.
The calculator adds 0.5" to each finished border width for seam allowances and calculates total linear inches needed per border. Strips are assumed to be cut cross-grain (across the width of fabric).
Each border's yardage is shown separately since borders are often different fabrics. The total at the bottom combines all borders — useful when planning a same-fabric or scrappy border set.
常见问题
How do I calculate quilt border yardage?
Measure the perimeter (2 × width + 2 × height) and add 8 × border width for corner overlap. Divide by fabric width to get strip count, multiply by cut width (finished + 0.5") for total yardage.
How wide should I cut quilt border strips?
Cut at finished border width + 0.5" for seam allowances. A 3" finished border = 3.5" cut width.
Can I use the same fabric for all borders?
Yes. The total yardage shown is the combined amount needed. If using the same fabric, you can cut all strips at once.
