FABRIC PLANNING
How to Estimate Fabric Consumption
Fabric consumption depends on pattern-piece area, marker efficiency, usable width, repeats, grain, nap, shrinkage, and production allowances.
SHORT ANSWER
Start with the inputs you can verify
Fabric consumption depends on pattern-piece area, marker efficiency, usable width, repeats, grain, nap, shrinkage, and production allowances.
What the estimate means
Simple area division misses the spaces created when shapes are nested on a marker.
Directional prints, nap, stripes, and checks can reduce marker efficiency.
Where estimates go wrong
Use usable fabric width after selvedges and defects, not the nominal roll width alone.
Keep the source measurements and assumptions with the result so another person can review or update the estimate later.
A practical workflow
- Confirm pattern pieces, sizes, quantities, and orientation rules.
- Estimate or measure marker length at usable width.
- Add shrinkage and process allowances separately, then validate with a sample marker.
