About FabricYardageCalculator.com
We build free fabric yardage calculators and reference guides so you never under-order or overspend on fabric again.
Why We Built This
“How much fabric do I need?” is one of the most common questions asked by homeowners, sewers, interior designers, quilters, and upholsterers. The answer depends on dozens of variables — furniture type, fabric width, pattern repeat, seam allowances, overage — and getting it wrong is expensive.
We built FabricYardageCalculator.com to answer that question quickly, accurately, and with transparent assumptions. Every calculator on this site is free to use, requires no signup, and shows its work so you understand exactly how the result was calculated.
What We Publish
Our site covers five core categories of fabric projects, each with a dedicated calculator and supporting guides:
Upholstery
Sofas, armchairs, ottomans, dining chairs
Sewing & Garments
Dresses, shirts, trousers, skirts, jackets
Curtains & Drapes
Any window size with fullness and lining
Quilting
Baby to king with per-colour breakdown
Cushions & Pillows
Throw pillows, bench cushions, floor cushions
In addition to calculators, we publish yardage reference charts, step-by-step guides, and fabric-specific buying guides to help you make informed purchasing decisions.
How We Calculate
Our calculator logic uses industry-standard formulas based on project-type base yardage, fabric width adjustments, pattern repeat multipliers, and configurable overage allowances. Results are rounded up to the nearest quarter yard — the standard increment at fabric retailers.
All formulas are documented publicly on our methodology page so you can verify the math. We believe transparency builds trust, and we want you to understand exactly how your result was derived.
Our Standards
Accuracy
Calculator formulas are tested against professional upholstery workroom estimates, commercial sewing pattern yardage charts, and quilting industry standards. We test representative input combinations and validate against real-world results.
Regular Review
Core calculator logic is reviewed quarterly. Reference charts and guide content are reviewed every 3–6 months. High-impact corrections are published immediately.
Independence
Where affiliate links appear, they are disclosed. Commercial relationships do not determine formulas, recommendations, or rankings. Our calculators recommend yardage, not brands.
Transparency
Every calculator shows a breakdown of how the result was calculated. The formula reference documents every calculation in detail. The review and correction process is published in full.
Disclaimer
All results are estimates for planning purposes. Actual yardage can vary by cutting layout, nap direction, motif alignment, workroom practice, and fabric behaviour. Always confirm final quantities with your fabric retailer or professional upholsterer before placing a large order.
