Yarn consumption per fabric calculator

From construction, width, order length and waste percentage, find an order’s total yarn requirement (kg, waste included).

Formula

Yarn per metre (g) = (warp + weft g/m²) × width(m). Total yarn (kg) = yarn per metre(g) × order_m ÷ 1000 × (1 + waste). Enter waste as a decimal: 4% → 0.04. Warp and weft g/m² come from the fabric construction (weight calculator).

Worked example

Warp 95 g/m² + weft 85 g/m² = 180 g/m²; width 1.5 m; order 1,000 m; waste 4% (0.04). Yarn per metre = 180 × 1.5 = 270 g. Total = 270 × 1,000 ÷ 1,000 × (1 + 0.04) = 270 × 1.04 = 280.8 kg. The no-waste figure is 270 kg; 4% waste adds 10.8 kg.

Frequently asked questions

How much yarn does a fabric need?

Total yarn (kg) = (warp + weft g/m²) × width × order_m ÷ 1000 × (1 + waste). E.g. 180 g/m², 1.5 m width, 1,000 m, 4% waste: 270 × 1,000 ÷ 1,000 × 1.04 = 280.8 kg.

What waste percentage should I use?

Waste covers knitting/weaving loss, selvedge, tie-in and sampling. Typical ranges are 3–6% for knits and 5–10% for wovens; use your own production data or our RFQ team for an exact figure.

Where do I get the warp and weft g/m²?

From the fabric construction: the mass per square metre of each yarn system. Their sum is the fabric’s total weight (g/m²), listed per fabric in our TDS sheets.

Is the result exact or estimated?

The result is estimated: actual g/m² measurement tolerance, shrinkage/finishing and the real waste rate all shift it. For a binding quantity, work from the TDS weight and an agreed waste figure.
