# Woven fabric consumption formula.

Learn Apparel Merchandising, Learn Fashion design.
Before calculate the woven fabric consumption, you must need the followings information as mentioned below:

1) Measurement chart with technical spec.
2) Style Description.
3) Fabric Description.
4) Fabrics width/weight.
5) Washing shrinkage if any.

This formula is as under :
Formula = Length  X Width  / Fab width X Fab Unit

Here,
Length = length of the specific parts + allowance
Width  = width  of the specific parts + allowance
Fab width = Fabric width ( after considering the shrinkage
allowance).
Say, fabric width is 45″ & the shrinkage
allowance is 1″, Then the Fabric width will
be (45″-1″) = 44″ in the formula.
Fab unit = Fabric calculation unit, here it will be 36 because
we are going to calculate the consumption in
Yards.

Now we will calculate the consumption of a Shirt (front part)
Center front length  = 32″+1″ (Sewing allowance) = 33″
Width (Chest)        = 24″ + 1″ (Sewing allowance) + 3″
Pleat.W (1.5X2)  = 28″

= Length  X Width  / Fab width X Fab Unit
= 33″ X 28″ /  44″ X 36″
= 924″ 1584″
= 0.5833333

= 0.59 Yards. (for front part)
