It is important to know how much fabric is needed to make your garments. Especially when you are mass producing the garments. Knowing how much fabric each garment consumes will allow you to calculate how much fabric you will need to order in total and how much it will cost you. However some fabric supplier will require you to order a minimum amount of fabric, which could mean you have to purchase 1 roll or a few hundred meters. It is always best to ask what that specific fabric supplier's MOQ is when enquiring about fabrics.
There are some factor that can change a garments consumption:
Grain Line: All pattern pieces need to follow the grain line that is marked on the pattern, therefore it is impossible to place the pattern pieces on the fabric just because it will fit.
Bias Cut: Some garments require the pattern pieces to be cut on the bias, therefore using much more fabric. So its important to create a lay plan so you can check how much more fabric you will need.
ROUGH FABRIC CONSUMPTIONS:
(Fabric width 145-150cm)
PANTS, FULL LENGTH - 2.05m
SHORTS, BERMUDA LENGTH - 1.15m
SHIRT, LONG SLEEVE
