Calculation Breakdown

Important:
  • Pre-wash fabric before cutting to account for shrinkage
  • Buy all fabric from the same bolt for color consistency
Pro Tip:
When in doubt, buy an extra 1/4 to 1/2 yard. You can always use scraps for testing or small projects!

Understanding Fabric Yardage

Accurate fabric calculation prevents costly mistakes. Always buy a little extra for matching patterns, potential errors, and shrinkage. Pre-wash fabric before cutting to account for shrinkage.

Common Fabric Widths

Width Common Uses
36" Quilting cotton, craft fabric
44-45" Standard apparel, cotton prints
54-60" Home decor, upholstery, knits
108-120" Quilt backing, sheeting

Fabric Buying Tips

  • Pre-wash: Most fabrics shrink 3-5% - pre-wash before cutting
  • Buy extra: Add 10-15% for errors and future repairs
  • Same bolt: Buy all fabric from the same bolt for color consistency
  • Check grain: Ensure fabric is on-grain before cutting
  • Nap fabrics: Velvet, corduroy need all pieces cut same direction
  • Save scraps: Keep leftover fabric for matching buttons, repairs

Shrinkage Allowance

  • Cotton: 3-5% shrinkage
  • Linen: 5-10% shrinkage
  • Rayon: 3-5% shrinkage
  • Polyester: Minimal shrinkage
  • Wool: Can shrink significantly - dry clean or hand wash

Frequently Asked Questions

How accurate are the results?
The Fabric applies a standard formula to your inputs — accuracy depends on how precisely you measure those inputs. For planning and estimation, results are reliable. For high-stakes or professional decisions, cross-check the output with a domain expert or primary source.
Can I use this on mobile?
Yes — the calculator is designed to work on any device. For complex multi-input calculations on small screens, landscape orientation gives more room to see all fields and results simultaneously.
How should I interpret the Fabric output?
The result is a calculated estimate based on the formula and your inputs. Compare it against the reference values or benchmarks shown on this page to understand whether your result is high, low, or typical. For decisions with real consequences, use the output as one data point alongside direct measurement and professional advice.
When should I use a different approach?
Use this calculator for quick, formula-based estimates. If your situation involves multiple interacting variables, time-varying inputs, or safety-critical decisions, consider a dedicated software tool, professional consultation, or direct measurement. Calculators are most reliable within their stated assumptions — check that your scenario matches those assumptions before relying on the output.
