How to Use the Fabric Consumption Calculator for Garments
- Select your desired options and garment / fabric specifications from the input fields above.
- Enter your measurements with high precision using the labeled unit selectors (inches, centimeters, or grams).
- Review the live calculation summary in the prominent result card to confirm fabric yardage, cuts, or conversions.
- Use the "Copy Specification" button to save your cutting specification to your tech pack or pattern notes.
Documented Textile Industry Formula
Garment Fabric Consumption Formula
- 1. Total Length = Body Length + Sleeve Length + Hem Allowance (6 cm)
- 2. Total Width = (1/2 Chest + Seam Allowance (4 cm)) × 2
- 3. Pattern Area per piece = Total Length × Total Width in cm² / 10,000
- 4. Weight per piece (g) = Area (m²) × GSM × (1 + Wastage %)
- 5. Consumption per dozen (kg) = (Weight per piece × 12) / 1,000
Worked Calculation Example
Real-World Scenario: A 220 GSM combed cotton crewneck t-shirt: 72 cm length, 54 cm half-chest, 22 cm sleeve, 7% wastage.
- • Length Factor = 72 + 22 + 6 = 100 cm
- • Width Factor = (54 + 4) × 2 = 116 cm
- • Area per Garment = (100 × 116) / 10,000 = 1.16 m²
- • Base Weight per Shirt = 1.16 m² × 220 g/m² = 255.2 grams
- • With 7% Wastage = 255.2 × 1.07 = 273.1 grams per piece
- • Consumption per Dozen = (273.1 × 12) / 1,000 = 3.28 kg / dozen
You need approximately 3.28 kg of 220 GSM single jersey fabric per dozen t-shirts (approx. 0.27 kg per shirt).
Frequently Asked Questions
What is the standard fabric consumption for a t-shirt?
For a standard adult cotton t-shirt (180–220 GSM), consumption ranges between 2.8 kg and 3.5 kg per dozen (approximately 0.23 to 0.29 kg per garment including cutting wastage).
Why is consumption measured in kg instead of yards for knitwear?
Knit fabric (single jersey, fleece, French Terry) is tubular or roll-knitted under varying tension, causing width and length to stretch. Measuring by weight in kilograms guarantees accurate yarn procurement regardless of roll relaxation.
How much fabric wastage occurs in garment cutting?
High-efficiency CAD marker layouts achieve 85% to 90% fabric utilization, meaning 10% to 15% is scrap/selvedge waste. For single garments, allow 5% to 8% wastage.
