In the apparel industry, the trouser is the most commonly produced items and also used widely in the garments sector. The most important task for a merchandiser is calculating fabric consumption for an order. If the final consumption of an order is not accurate then the manufacturer will face a huge problem and may lose its reputation.

For calculating fabric consumption for an order, consumption determination of fabric is a very important term in the textile sector. Since it depends on fabric prices therefore accurate and closure consumption will reduce fabric wastage which will be beneficial for producing trousers with a competitive cost. So, we should keep proper knowledge of fabric consumption properly.

The basic formula of fabric consumption:

To estimate fabric consumption for a knitted apparel use the following formula.

Consumption in grams= {(L*C) + (B*SL)}*2*GSM/10000 grams 

Where,
C= Chest +allowance
L= length of the body measure + allowance
SL= Sleeve length +Allowance
B=Biceps +allowance
GSM = fabric weight in grams per square meter

For example: If you consider,

  • Outseam = 42 inch
  • Inseam = 32”
  • Waist = 36”
  • Hip = 40”
  • Bottom = 20 “
  • Fabric width =58”

The mathematical formula to calculate the fabric consumption of trouser in the yard is given below:

Formula =

= [ (42” + 2” + 2”) × (Hip/4 + 1.5”) × 4/36”] / 57”

= [ 46” × (40”/4 + 3”) × 4/36”] / 57”

=[ 46” × 13” × 4/36”] / 57”

= 1.165 yd/ per trouser

= 1.165 yd/ per trouser + zipper fly (2) + pocket facing (4) + back pocket bone + belt loop

= 1.165 + 0.058

= 1.21

= 1.21 + 5%

= 1.21 + 0.060

= 1.270 × 12 (per doz)

= 15.24 yard/doz

Trouser is one of the common garment manufacturing items in the apparel industry. Knitted Trousers can be made from fleece fabric or a single jersey. The calculation process of fabric consumption for trousers is the same for both fabric types.
