How do I calculate fabric consumption for a garment?

Add up the area of every panel in the tech pack — length × width × pieces — divide by the usable width of the cloth, and add the wastage your marker runs. A shirt whose panels total 10,000 cm² on 150 cm cloth takes 0.67 m before wastage.

What is the fabric consumption formula?

Metres per garment = panel area in cm² × (1 + wastage) ÷ (width in cm × 100). Kilos per metre = GSM × width ÷ 100,000. Multiply the two for the weight per garment, and the per-garment figures by the order quantity for the order.

How much wastage should I allow?

Whatever your marker actually runs — the field defaults to zero so the base answer is pure arithmetic. Marker efficiency is programme-specific: it depends on the panel shapes, the size run and how the marker is nested, so it is your cutting room's figure to state, not this page's to assume.

How many garments does a 5,000 m order cover?

Divide the order metres by the metres per garment the tool reports. At 0.70 m per garment, 5,000 m covers about 7,140 garments. 5,000 m is the published floor for most woven and finished routes on this mill, so the consumption figure is what turns an MOQ into a garment count.

Fabric consumption calculator

Work out fabric consumption per garment from the panel list: linear metres and kilos at your width and GSM, with a wastage allowance and order totals.

Why a consumption calculator belongs on a mill site

Fabric consumption is the buyer's arithmetic: the tech pack lists panels, the marker wastes a percentage, and the order is quoted in metres and kilos. This tool does that arithmetic on the panels you state — the same panels your cutting room will lay — so the number on the RFQ is the number the order needs. Nothing here is an industry average.

The arithmetic

The wastage allowance is your marker's figure, not a convention this page assumes — it defaults to zero, so the answer is the arithmetic on your panels and nothing else.

panel area = Σ (length × width × qty)
effective area = panel area × (1 + wastage ÷ 100)
metres per garment = effective area ÷ (width × 100)
kg per metre = GSM × width ÷ 100,000
kg per garment = metres per garment × kg per metre
order = per-garment figure × garments
