Consumption for Knit Garments:
Knit fabric consumption calculation is one of the most important part of knit garment Merchandising. It plays important rules in costing of garments. Firstly, you've to know what you going to make or about the measurement? All measurement has it length and width. The standard measurement for weight and quality of knit fabrics is grams per square meter (GSM).
 Knit garments
To calculate the knit fabric consumption following information is required:
1. Body length of the garment in cm. Suppose it is - 70 cm+5cm (Sewing allowance)=75cm c. Sleeve length of the garment in cm. Suppose it is 20 cm+5cm (Sewing allowance)=25cm
2. 1/2 Chest width in cm. Suppose it is 48 cm+2cm (Sewing allowance)=50cm
3. Armhole circumference in cm. Suppose it is-40cm+2cm (Sewing allowance)=42cm
4. Fabric GSM. Suppose it is 180 gsm
5. Percentage of fabric wastage. Suppose it is 10%
Formula for Fabric of Knit Garments Consumption:

{(Body length + Sleeve length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage%

Here,
Body Length = in CM
Sleeve Length = in CM
Chest/Bottom (most widest part) = in CM
GSM = gm/m2

Example for 1 dozen garments:
{(Body length + Sleeve length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage%

= {(73 + 19.5 + 10) X (52 + 4)} X 2 X 160 X 12 / 10000000 + 10%

= (102.5 X 56) X 2 X 160 X 12 / 10000000 + 10%

= 5740 X 2 X 160 X 12 /10000000 +10%

= 22041600 / 10000000 + 10%

= 2.20416 + 10 %

= 2.424576

= 2.43 kg per dozen.
