Woven fabric consumption formula.

Learn Apparel Merchandising,
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)
