The garment manufacturing business is similar to other businesses; every factory is set for profit generation. In the garments industry, fabric consumption is an important factor and task for merchandisers. Profit can be maximized by saving on each cost factor of garment making. Fabric is the most important factor in making garment products, accounting for almost 50 % to 70% of the total product-making cost. Garment-making cost depends on the fabric and, for order, how much fabric is needed to fill up the order, including cut wastage. That’s why fabric consumption must be calculated accurately to maximize the profit from an order.
Most of the garment industry uses a cad marker for fabric consumption by the technical pattern master. No one bothers about how it is done. If we have a product technical sheet, we can calculate the fabric consumption of the garment using the technical sheet. Also, I need specific fabric information, like - whether the fabric is a solid or all-over print, chest print, stripe or any specific design. For better understanding and calculation, follow the below example;
The basic formula of fabric consumption:
Formula - 01: In centimetre
(Body Length + Sleeve Length + Seam Allowance) x (? Chest + Seam Allowance) x 2 x GSM / 10,000 x 1000 + 10% (Wastage and extra cutting) x Doz. + TF (Trim Fabric)
Formula - 02: In Inch?
(Body Length + Sleeve Length + Seam Allowance) x (? Chest + Seam Allowance) x 2 x GSM / 1550 x1000 + 10% (Wastage and extra cutting) x Doz. + TF (Trim Fabric)
To estimate the fabric consumption for knitted Basic T-shirts, we will use above one of the formulas. Some basic information is needed to estimate fabric consumption. They are -
Formula - 01: If garment measurement is used in CM (Centimeter)?
Suppose a knitted basic T-shirt has been following information. We need to estimate the product's fabric consumption.
Item: Knitted basic T-shirt garment components are front, back and short sleeves. Fabric GSM (Gram per square) is 160.
MeasurementCentimeter
Body Length (BL) 46.5 cm
sleeve Length (SL)14 cm?
Chest34 cm
MeasurementCentimeter
Body Length (BL)= 46.5 cm + 4 cm = 50.5 cm
Sleeve Length (SL)= 14 cm + 4 cm = 18 cm?
Chest= 34 cm + 4cm = 38 cm

As per the above measurement of this style, fabric consumption is;
= (BL + SL) x ? Chest x 2 x GSM / 10,000 x 1000 + 10% Wastage x Doz. + TF
= (50.5 + 18) x 38 x 2 x 160 / 10,000 x 1000 + 10% x 12 + TF= 1.0995 + 0.15
= 1.25 kg / Doz.
Formula - 02: If garment measurement is used in Inch?
Item: Knitted basic T-shirt garment components are front, back and short sleeves. Fabric GSM (Gram per square) is 160.
Measurements without allowanceInch
Body Length (BL)18.307 inch
Sleeve Length (SL)5.511 inch?
Chest13.386 inch
Measurements with allowanceInchBody
Length (BL)= 18.307 inch + 2 inch = 20.307 inch
Sleeve Length (SL)= 5.511 inch + 2 inch = 7.511 inch?
Chest= 13.386 inch + 2 inch = 15.386 inch
As per the above measurement of this style, fabric consumption is;
= (BL + SL) x ? Chest x 2 x GSM / 1550 x 1000 + 10% Wastage x Doz. + TF
= (20.307 + 7.511) x 15.386 x 2 x 160 / 1550 x 1000 + 10% x 12 + TF
= 1.166 + 0.15 = 1.3164 kg / Doz.
Please note that we used the above formula to estimate only the fabric weight a garment consumes. Using the above formula, we didn’t include fabric loss due to fabric width, marker process loss, dying process loss or any defects. When we purchase fabric from mills, we must consider all these parameters.
