Quilt Backing & Wide-Back Yardage Calculator

Use this calculator to estimate quilt backing requirements for standard-width quilting cotton or wide-back fabric. Enter your quilt-top dimensions, choose your preferred backing type, set the usable fabric width and quilting allowance, and the calculator will estimate how many linear yards you need.

Important: If a longarm quilter will quilt your project, use the extra backing allowance they require.
