How to Measure Fabric Consumption of Garments?
Introduction:
Like other business, garment factory is about for profit generation. Profit are often Improved by saving from each cost factors of garment making. Fabric Consumption Is most vital constitute of garment and It represent around 60-70% of total product manufacturing cost. Fabric cost of a product depends what proportion fabric ls consumed to form the garment including cut wastes and end bits. So fabric consumption must to be calculated accurately
Most of the Indian apparel factories fabric consumption is formed by pattern masters. remainder of the workers don’t bother how it’s done. If you’ve got product technical sheet then you’ll calculate the precise fabric consumption of a garment. Average fabric consumption also depends on nature of the material , like tubular or open width fabric. Whether fabric is solid coloured, check or stripe or any specific design repeat required. In following one example has been shown with formula for better clarification about the caiculation.
Basic formula:
To estimate fabric consumption for a knitted top use following formula. Consumption in grams: {(L*C) + (C*SL)}*2″I‘GSM/10000 grams (when length units are In centimeter)
Where,
C= Chest + Allowance
L=Length of the body Measure +allowance
SL=Sleeve Length + Allowance
B=Biceps + Allowance
Gsm=Fabric weight in grams per sm
Example: Product-knit top.Garments components are front, back and sleeves.

Chest= 23.25”
Body length=30.5”
Sleeve length=26”
Bicep=9.2”
Fabric GSM=200
|
+1.75”=25”
+2.50”=33”
+1.5”=27.5”
0.80”=10”

Calculation:
As Per above formula consumption
[(Length*Chest)+(Biceps*Sleeve Length)]*2*GSM
= ___________________________________________ Grams
10000
[(33*25)+(12*2*27.5)]*2(2.54*2.54)*200]
= _____________________________________Grams
10000
Note :2.54 is inch to cm convert factor
[(825+550)*400*6.45]
= ____________________ Grams
10000
=354.83 Grams
