Strip sequence

This is a straight-grain estimate. Bias binding and scalloped edges use different geometry.

01

How binding yardage is calculated

We add the quilt perimeter and your working allowance, divide by usable width of fabric for strip count, then round the fabric depth upward.

Perimeter

Measure all four sides

Finished width and length create the base distance the binding must cover.

Allowance

Add room to finish

The extra length supports corners and joining the two binding ends.

Strips

Cut across WOF

Strip count uses your entered usable width; fabric depth uses the selected cut strip width.

Binding questions

Check the method before cutting every strip.

How much extra length should I add to quilt binding?
Twelve inches is a common working allowance for joining the ends and handling corners, though your method or pattern may call for more.
What strip width should I use for double-fold binding?
Many quilters start with 2.25- or 2.5-inch strips. Batting thickness, seam allowance and the desired finished look can change the cut width.
Does this calculator work for bias binding?
No. This version estimates straight-grain crosswise strips cut across the width of fabric. Bias binding needs a different layout and more fabric.
