Fabric Calculator
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
What is a standard fabric width?
Common fabric widths are 45 inches (quilting cotton, lightweight fabrics) and 60 inches (apparel fabrics, knits). Upholstery fabric is often 54 inches.
What is pattern repeat?
Pattern repeat is the distance before a printed or woven pattern starts over. You need extra fabric to match patterns across panels.
