Note:

•     Types of fabric and fabric GSM will be confirmed by the buyer.
•     For body length and sleeve length, approximate sewing allowance (12cm) should be needed at body hem, shoulder joint, sleeve hem and armhole joint.
•     For chest width, approximate sewing allowance (6cm) should be needed at both side seams.
•     And approximate fabric wastage in various stages is 10%.

Now, I will provide an example for knit fabric consumption in the following. After that, all the confusion about the above discussion will be cleared I think.

Example:

Suppose, one of the buyer has provided you the following measurement chart of a basic T-Shirt by mentioning the order quantity and fabric GSM. (Where Fabric is 100% cotton single jersey and fabric GSM is 160 and order quantity is 10000pcs). Then calculate the fabric consumption for this order.

Solution:

Here, we will follow the measurement chart for XL size.

•     Fabric GSM- 160,
•     Total order quantity- 10000
•     Body length or shirt length- 79cm
•     Sleeve length- 43cm
•     ½ Chest width- 61cm

Now, all the measurements are applied on the following formula-

= 3.45 + 10% (in kg)
= 3.795 kg per dozen.
