Introduction:
It is very important task for merchandisers about clear concept on correct fabric consumption and costing. Because fabric cost bears the 40% to 45% of the total cost of any garments.
 Knitted T-shirt (Front & Back)
Fabric Consumption for Knitted T-shirt:
These are some basic function to make consumption of a knitted t-shirt, such as-
1. Fabric type and weight (Single jersey 145 GSM)
2. Basic measurement (1/2 Chest, Back length and sleeve length)
3. Sewing allowance
4. Wastage (Cutting and Sewing- 10%, 15% etc.)
Suppose,
• Length = 70 cm
• ½ Chest = 60 cm/dia
• Sleeve length = 25 cm
• Arm hole width = 40 cm
• GSM = 145
Formula =

[( Back length + Sleeve length) × ½ Chest ×2×GSM×12] / 10000000

= [{(70 + 5) + (25 + 5)} × 60 ×2×145×12] / 10000000

= 2.28 kg + 7 %

= 2.28 kg + 0.159

= 2.439 kg/doz [Neck and sleeve are made rib so add 0.10]
