Fabric Consumption:
The quantity of fabric required for making a garment is called the consumption of fabric. After making of sample garments, in order to determine its cost, needs to find out the consumption of fabric. It is very difficult to say that how much fabric will be required for making a specific garment, before completion of marker planning for that garment. Nevertheless, after making of the sample garment or by seeing the sample garment, consumption calculation of fabric can be found out. But it is to be kept in mind that the consumption of fabric found out seeing the sample garment will be the approximate consumption. How to find out the consumption of fabric for a full shirt and a trouser, have been shown below with the help of figures-1 and 2.
The consumption for a shirt = Z
Z = X + Y
X = (A +3”) x (B + 3”) x 2 sq. inch
Y + (C + 2”) x (2D + 2”) x 2 sq. inch
Figure – 1 (Full sleeve shirt)
Where,
A = Length of the shirt
B = Width of the shirt (along the chest)
C = Length of the sleeve
L = Width of armhole
Using the above formula, the quantity of fabric to be required for making a shirt, can easily be found out. If the width of the fabric is known, the length of the fabric could also be found out. With the help of example-1, the system of finding out of consumption of fabric for a shirt is shown below:
Example-1
By measuring a sample garment (full sleeve shirt) it is found that the maximum length of the shirt = 32”, the width of the shirt (along the chest) = 25”, the length of the full sleeve (top) = 22”, and the width of the armhole = 10”. Estimate the quantity of fabric to be required to make the shirt, if the width of the fabric = 44”.
Solution:
As per the question:
A = 32”
B = 25”
C = 22”
D = 10”
Therefore,
X = (A + 3”) x (B + 3”) x 2
= (32” + 3”) x (25” + 3”) x 2
= 35” x 28” x 2
= 1960
Y = (C + 2”) x (2D + 2”) x 2 sq. inch
= (22” + 2”) x (2 x 10” + 2”) x 2
= 1056 sq. inch
Fabric Consumption: (Z) = X + Y
= 1960 + 1056
= 3016 sq. inch ——————————————– (1)
When the width of fabric = 44”
The length of the fabric = 3016”/44”
= 68.54 inch ————————————————- (2)
With the help of figure – 2, the system of finding out consumption for a trouser has been shown:
In normal condition, a trouser (pant) looks like the figure-2 (A), for finding out fabric consumption, it (the pant) is to be folded as fiqure-2 (B), and the measurement of “H” and “J” have to be taken.

The fabric consumption for pant (P) = (H + 4”) x (J + 2”) x 4 (without pocketing fabric)
P = The fabric consumption for pant (sq.inch)
H = The height of the pant
J = The ½ width along the crotch line
Example-2
By measuring a sample of a pant, it is found that it height (H) = 40”, and ½ width (along crotch line) = 13”. Determine the consumption calculation of fabric for making this pant. If fabric is supplied in 60” width, then what will be the length of the fabric.
Solution:
Consumption of pant (P) = (h + 4”) x (J + 2”) x 4
= (40” + 4”) x (13” + 2”) x 4
= 44” x 15” x 4
= 660 x 4 sq. inch
= 2640 sq. inch
If the width of the fabric = 60”, then
Then length of the fabric = 2640/60
= 44” will be required.
It is mentionable here that here in finding out the consumption calculation of fabric for the pant, pocketing fabric and lining have not been included. Based on the number of pockets in the pant, the consumption of pocketing fabric will be required to be found out separately.
