Enter the marker, the order size ratio and the fabric to see how much fabric each garment uses, how much to buy for the order and how many rolls to pull for cutting.
Pre-sizing and estimating tool: results do not replace design, calculations or reports signed by a licensed professional, nor verification against the applicable codes and standards.
Fabric length per garment of each size, including end loss and roll losses. Without pattern areas, every size gets the average.
Fabric area bought per garment (full width), split into pattern pieces and losses.

It tells you how much fabric each garment uses (yards, square feet and pounds), how much fabric to buy for an order with a size ratio and how many rolls to pull for cutting. Use it to quote a new style, plan the cutting room or check whether the spec sheet consumption is realistic.
The marker is the layout of all pattern pieces on the usable width of the fabric. Efficiency is pattern area divided by marker area. In the example, 6 T-shirts (1 S, 2 M, 2 L and 1 XL) add up to 62.7 ft² of pattern pieces on a 4.4 yd by 68 in marker, about 83.8% efficiency.
Each 4.4 yd ply plus 1 in of end loss yields 6 T-shirts; with 2% roll losses the average is 0.753 yd per garment, or 13.2 ft² and 0.43 lb of 4.7 oz/yd² jersey 70 in wide. The 1,800-garment order needs 300 plies, 3 spreads of up to 100 plies, about 1,355 yd (774 lb) and 15 rolls of 55 lb.
Pattern area comes from the CAD system (piece or marker report); add up all pieces of one size (front, back, sleeves, collar). Fabric weight is on the supplier spec sheet or measured by cutting and weighing a sample of known area (ASTM D3776). Without areas, use finished marker mode with the efficiency from the CAD.
Apparel markers usually use 70% to 90% of the area, with 1 to 2 in of end loss per ply and 1% to 3% roll losses. T-shirt jersey is around 4 to 5.5 oz/yd², and a basic adult T-shirt takes roughly 0.4 to 0.55 lb of fabric. Compare with your own cutting records before adopting a standard.
Using full width on the marker (markers are made on usable width), forgetting end and roll losses, and buying fabric from the consumption of a single size. Another is a marker ratio that does not match the order, which cuts extra garments; the calculator flags it. Shrinkage, stripe matching and linings are not included.
It depends on size, fabric width and the marker. In the example, with 70 in jersey and a 6-garment marker, the average is 0.75 yd per garment, from about 0.66 yd for S to 0.85 yd for XL. To quote, take the consumption in yards or pounds to the garment cost calculator.
