Calculate how many yards of fabric you need for a sewing project. Plan pattern layout, width, and repeats to buy the right amount of material.
Calculate quilt backing fabric needed including overhang and seam allowance. Size backing for longarm, domestic machine, or hand quilting projects.
Calculate seam allowance adjustments for pattern alterations and garment fitting. Add or subtract ease when resizing or modifying sewing patterns.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Binding = 2 × (Width + Height) + 12 in overlap; Strips = Ceiling(Length ÷ Fabric Width)The calculation requires: Quilt Width (inches), Quilt Height (inches), Binding Strip Width (inches), Fabric Width (inches). Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

When a formula combines multiple measurements, all inputs must use compatible units. Convert everything to the same system (metric or imperial) before calculating.
Calculate binding strip length and yardage for a quilt. Free quilt binding length calculator for quilting projects, patchwork, and fabric layout. It applies the calculation formula (Binding = 2 × (Width + Height) + 12 in overlap; Strips = Ceiling(Length ÷ Fabric Width)). For example: 60×72 in quilt, 2.5 in binding strips — A typical use case demonstrating the calculator with representative values.
