Calculate Fabric Needed

Formula

Panels = ceil(project width / fabric width). Length/panel = project length + pattern repeat adjustment + 2" seam. Total yards = (panels × length per panel) / 36.

Frequently Asked Questions

Pattern repeat is the distance before a printed or woven pattern starts over. You need extra fabric to match patterns across panels.
