Fabric Consumption Calculation
Consumption of fabric is a very important and tough work in apparel industry. Because profit of apparel business maximum depend on perfect costing. So merchandiser should do this work carefully.
For determination of fabric consumption of any parts of a t-shirt, we have to take reading length and maximum width of this part of t-shirt. And then we have to multiply length with width to find out the area of fabric required of this part and other should be followed as unit terms.

Measurement Chart:
1. Sleeve length: -------------------------76 cm
2. ½ chest width: -------------------------58 cm
3. Body length: ---------------------------24 cm
4. Sleeve hem width: ---------------------2.5 cm
5. Bottom hem width: --------------------2.5 cm
6. Neck width: (1+2+3+4+5): -----------21 cm
7. Neck rib width: -----------------------2.5 cm
8. Fabrics weight: -----------------------180 GSM (Single jersey)
Note: GSM= Gram per square meter
For knit fabric (Single jersey), GSM may be from 110-520

Consumption of Basic T-shirt:

Body length = 76 + 2.5 (hem width) + 3.5 (seam allowance) = 82 cm

Sleeve length = 24 + 2.5 (hem width) + 3.5 (seam allowance) = 30 cm

½ Chest width = 58 + 6 (seam allowance) = 64 cm

Consumption Formula:

= { ½ chest X (Body length + Sleeve length)} X 2 X GSM / 10000000 + wastages % Kg/piece

= {64 X (82 + 30) X 2} X 180 / 1000000 + 10%

= 0.25 + 0.02

= 0.27 Kg/pc

= 0.27 X 12 Kg/doz

= 3.24 Kg/doz

Neck consumption = 150 gm/doz =0.15 Kg/doz

Tapping or piping consumption = 50 gm/doz = 0.05 kg/doz

Total consumption = 3.25 + 0.15 + 0.05 = 3.44 Kg/doz

Fabric consumption for 1 dozen basic short sleeve t-shirt is 3.44 Kg (ANS)
