Basic Denim Long Pant Consumption

We have the bellow measurement of a "Basic Denim long pant" :-

Inseam = 34 inch,
½ Thai= 13 inch,
Back rise (Under West Band) =15 Inch
Waist band width =1.5 inch,
Back pocket length = 7 inch,
Back pocket Width = 6.5 inch
Belt Loop length =1.5 inch,
Belt Loop Width = 1/2 inch
Pocket Bag Length = 7.5 inch
Pocket Bag Width = 6.5 inch

The Formula is : ( Length X Width ) X No of panel / ( Fabric Width X 36 inch ) + Wastage Percentage

= Result X 12 Pcs

Calculation: - In Here

Total Bottom Length = Inseam + Back rise + Wbw + Sewing allowance.( Wbw =West band width )

Total Bottom Width = 1/2 Thigh +2“ Sewing allowance

So, Length = 34+15 + 1.5 *2 +3 = 55 Inch.
Width = 13 +2 =15 Inch

Say the actual Fabric Width is 58 inch, but when sewing a garments as we can’t use the edge of a fabric , so at the time of calculation we must deduct 1 Inch from the fabric width . I.e. fabric width will be 57 Inch.


Now the Applicable Formula :-

( Length X Thigh ) * 4 part /( Fabric Width X 36 inch)

= Result + 5 % Wastage

= Result for 1 Pc X12 pcs

= Yds / Doz

Based on above information we found

Main Fabric Consumption :- (55 Inch X 15 Inch) X 4 Pcs /57 inch X 36 Inch + Wastage 5% X 12 Pcs

=( 3300 square inch / 2052 square inch )+ 5% Wastage X 12 Pcs

= {1.61 Yds +0.08(Wastage)} X 12 Pcs

= 1.69 Yds X12 Pcs

= 20.28 Yds /Doz.


Back Pocket Consumption = (7”X 6.5 )=44.5 X 2 pc / 57 X 36 =91 /2052 =.044 +.0022=.047 X12 Pcs

= 0.56 Yds / Dz

Belt loop Consumption = (1.5”X .5 ) = .75 X 6 pc / 57 X 36 =4.5 /2052 =.0022 +.0001=.0023 X12 Pcs
= 0.028 Yds / Dz

Total Fabric =20.28 yds +0.56 Yds+0..28 Yds = 20.84 Yds / Dz

For Pocketing Fabric :- Length =7 .5 inch X 2 Ply +1 inch (SA )=( 15+1) inch = 16 inch

Width = 6.5 inch X 2 Ply + 1 inch (SA )= 14 inch

= ( 16 inch X 14 inch )2 pcs /(43 inch X 36 inch)
= 448/1548

=.29+5% wastage=.28+.0145=0.30X 12 Pcs =3.65 Yds Per


So we can say, based on above measurement we need 20.84 Yds main fabric & 3.65 Yds pocketing fabric to make 12 Pcs Basic long pant. this way we can calculate fabric consumption for any quantity.
