Planning Cushion Fabric
A cushion yardage plan should reduce waste before cutting begins. Fabric is sold by length, yet every cushion uses area. The calculator converts panel sizes into continuous yardage. It also adds seam allowance, boxing, zipper allowance, piping strips, repeat matching, and cutting waste. These details matter because a small cushion set can still require extra length when fabric has a large motif.
Why Yardage Changes
Cushion style changes the estimate. A knife edge cushion uses two flat panels. A boxed cushion needs top panels, bottom panels, and side boxing. A round cushion adds circles and a curved boxing strip. A bolster uses a rectangle for the body and two round end pieces. The tool separates these shapes, then combines their fabric demand. Fabric width also matters. Wider fabric often needs fewer running inches. Narrow fabric may require more length and more joins.
Statistical Planning Value
This calculator treats yardage as a planning estimate, not only a single number. It shows raw yardage, adjusted yardage, waste allowance, and rounded buying yardage. These values help compare risk. The mean yardage per cushion is useful for repeated work. The buffer percentage shows how much safety remains after rounding. A higher buffer is helpful for striped, floral, or directional fabric. It also protects against measuring errors.
Cutting and Matching
Pattern repeat can increase the final length. The calculator rounds fabric length upward to the next repeat interval. This helps align prints across cushions. Seam allowance is added to every panel edge. Boxing depth is expanded before fabric area is calculated. Piping adds strip area when selected. Zipper allowance adds extra area for closure construction.
Buying Guidance
Use the result as a careful buying guide. Always inspect the fabric before final cutting. Check nap, pattern direction, flaws, shrinkage, and shop cutting practices. Buy a little more when the fabric is expensive, rare, or hard to reorder. For professional upholstery, test one cushion first. Then update dimensions using the real cut pieces. This keeps the final order practical and defensible.
Record Keeping
Save each estimate after measuring. CSV files support job notes and comparisons. PDF copies help clients review quantities. Clear records make repeat cushion orders faster later with fewer costly buying surprises.
