Quilt Backing & Wide-Back Yardage Calculator

Estimate how much backing fabric you need for standard-width quilting cotton or wide-back fabric. Add your quilting allowance, choose the fabric width, and we'll round the purchase recommendation up to the next quarter yard.

Use this when: you know the finished quilt-top size and need a practical backing purchase amount. If a longarm quilter is finishing it, ask for their required extra backing first.

How this calculator works

Your entered allowance is added to all four sides. The calculator determines how many fabric widths are needed and the total linear yardage. For non-directional prints, it also checks whether rotating the backing would use less fabric.

Before you buy

Not included: pattern-repeat matching, unusually large seam allowances, prewashing shrinkage, or extra fabric beyond the quilting allowance you enter. When a fit is very close to the entered fabric width, the calculator will flag it so you can verify actual usable width.

Compare common backing widths

See the tradeoff before you buy. Fewer seams can mean easier preparation; lower yardage does not always mean lower total cost.
