Consumption Formula of Shirt and Pant in Apparel Industry

Shirt and pant are very common and popular dress for both men and women. So these two garments are manufactured in apparel industry in bulk quantity. Consumption calculation is a very important term in apparel merchandising. Because fabric covers the greatest part of garments costing (more than 60%), so apparel merchandiser should have better knowledge about fabric consumption calculation. Applying consumption formula of shirt and pant, garment merchandisers calculate fabric. In this article I will explain procedure of consumption formula of shirt and pant. At first I will calculate fabric of individual parts of garment and then add all parts.

Consumption Formula of Shirt:

A measurement chart of a shirt is given below:

Measuring Point Inch
Full length 31
½ Chest 22.50
Across shoulder 19
Back Yoke height 3.50
Sleeve length 34.50
Sleeve width 18
Sleeve opening 9
Cuff height 2.50
Collar width 16
Collar height (with neck band) 3.50
Chest pocket width 5
Chest pocket length 6
Fabric width 56

Front part:

(Full length + SA) x (1/2 Chest + SA + Placket)      [SA = Sewing Allowance]

= (31 + 1) x (22.50+1+2)

= 816 inch2

 

Back part:

(Full length – Back Yoke Height + SA) x (1/2 Chest + SA)

= (31-3.5+1) x (22.50+1)

= 669.75 inch2

 

Yoke:

(Yoke height + SA) x (Across shoulder + SA) x 2

= (3.5+1) x (19+1) x 2

= 180 inch2

 

Sleeve:

(Sleeve length – Cuff height + SA) x (Sleeve width + SA) x 2

= (34.5-2.5+1) x (18+1) x 2

= 1254 inch2

 

Collar:

(Collar height + SA) x (Collar width + SA) x 2

= (3.5+1) x (16+1) x 2

= 153 inch2

 

Cuff:

(Cuff height + SA) x (Sleeve opening + SA) x 2 x 2

= (2.5+1) x (9+1) x 4

= 140 inch2

 

Pocket:

(Pocket length + SA) x (Pocket width + SA)

= (6+1.5) x (5+1)

= 45 inch2

 

Total Fabric (in inch2) = Front + Back + Yoke + Collar + Sleeve + Cuff + Pocket

= 816 + 669.75 + 180 + 1254 + 153 + 140 + 45

= 3257.75 inch2

 

Fabric consumption per dozen:

Consumption Calculation of a Pant:

Parts-of-pant
Fig: Parts of a pant

A measurement chart of a pant is given below:

Point of Measurement Inch
Full length 43.25
½ Thigh 12
Waist band height 1.25
½ Waist 18
Fly length 5
Fly width 1
Belt loop length 1.25
Belt loop width 0.5
No. of belt looks 8
Pocket length 9
Pocket width 7
Fabric width 46
Pocketing fabric width 38

Leg panel:

Length x Width x 4

= (Full length – Waist band/Belt height + SA) x (1/2 Thigh + SA) x 4

= (43.25-1.25+2) x (12+1) x 4

= 2288 inch2

 

Waist band:

(Waist band height + SA) x (1/2 Waist + SA) x 2 x 2

= (1.25+1) x (18+1) x 4

= 171 inch2

 

Total fabric (in inch2) = Leg panel + Waist band

= 2288 + 171

= 2459 inch2

 

Fabric consumption per dozen

consumption formula of shirt

2459 x 12
= ———————– + 5%
48 x 36

= 17.93 yds/dzn

 

Pocketing fabric:

(Pocket length + SA) x (Pocket width + SA) x 2 x 2

= (9+1) x (7+1) x 4

= 320 inch2

 

Pocketing fabric consumption per dozen

consumption formula of shirt

320 x 12
= —————– + 5%
38 x 36

= 2.95 yds/dzn

Answer:

Body fabric = 17.93 yds/dzn

Pocketing fabric = 2.95 yds/dzn
