Fabric Consumption Short Theory.
Fabric Consumption Short Theory:
Fabric Consumption is very important for a probationer of management & merchandizing. As 60% to 70% cost of a garments comes from fabric. During fabric consumption, please consider wastage minimum 5%
1.Exp- A fabric piece of Length 10 yards, Width 40 inches & GSM 180, find out its weight in kg?
Answer- 10*36*40*180/1550000 =1.67 kgs
Formula- length*width*GSM/1550000 (1 yard= 36 inches)
Firstly, you have to convert the fabric length into inches, as you see we have fabric length in yard & Wight is in inches. please note, divided value "1550000'' is used if the measures of fabric is mentioned in inches or yards. For cm & meters, the value will be changed.
2.Exp- A fabric roll of length 70 meters, width 48 cm, GSM 200, find out the fabric roll's weight in kg?
Answer-70*100*48*200/10000000 =6.72 KGs
Formula- length*wight*GSM/10000000 (1 yard= 36 inches)
Firstly, you have to convert the fabric length into cm (centimeter), as you see we have fabric length in meters & wight is in cm. please note, divided value "10000000'' is used if the measures of fabric is mentioned in cm or meters.
3.Exp-2 KG'S fabric with length 15 yards,width 28 inches, find out it's GSM
Answer- 2*1550000/15/36/28 =205gsm
Formula- Kg*1550000/length / wight (1 yard = 36 inches)
Here value ''36'' is used to convert fabric's length into inches,because we have fabric length in yard & width is in inches.please note,divided value "1550000'' is used if the measures of fabric is mentioned in inches or yards. For cm & meters,the value will be "10000000"
4.Exp-2 kgs fabric with length 14 meters,width 71 cm,find out it's GSM?
Answer-2*10000000 / 14/ 100 / 71= 201
Formula- Kg*10000000 / length / width (1 meter= 100 centimeter)
Here value "100'' is used to convert fabric's length into centimeter, because we have fabric length in meter & width is in cm. please note,divided value ''10000000'' is used if the measures of fabric is mentioned in cm or meters.
5. Exp- A basic pant of length 40 inches, width 12 inches, GSM 210, find out its fabric consumption in KGs?
Answer- 40*12*4*210 / 1550000 + 5% = .27 kg
Formula- length * width * 4 * GSM / 1550000 + wastage % (this formula is applied if the measurement of pant is in inches,for cm measurment value ''15500000'' will be changed. value ''4'' means the pant has four panels or sides)
Please Note,all measurements mentioned in this book are imaginary. Merchandiser of a factory always calculated consumption of something i dozen. But I've calculated in piece. You need multiply the outcome with 12 to convert consumption in dozen.

5. Exp- A basic pant of length 40 inches, width 12 inches, GSM 210, find out its fabric consumption in KGs?
Answer- 40*12*4*210 / 1550000 + 5% = .27 kg
Formula- length * width * 4 * GSM / 1550000 + wastage % (this formula is applied if the measurement of pant is in inches,for cm measurment value ''15500000'' will be changed. value ''4'' means the pant has four panels or sides)
Please Note,all measurements mentioned in this book are imaginary. Merchandiser of a factory always calculated consumption of something i dozen. But I've calculated in piece. You need multiply the outcome with 12 to convert consumption in dozen.
The photo below shows you a pant's Length & width.
6.Exp-A pant with Length 100 cm, Width 30 cm, GSM 210, Figure out it's fabric consumption in KGs/dzn? (1 dozen = KGs?)
Answer- 100*30*4*210 / 10000000 + 5% *12= 3.18 Kgs.
Formula- (length * width * 4 * GSM / 10000000 + 5%) * 12 (This formula is applied if the measurement of pant is in cm)
7. Exp- A pant of length 40 inches, width 12 inches , you have a fabric of width 34 inches, find out 12 (dozen) pant's fabric consumption into yards?
Answer- (40*12*4/34/36+5%)*12 = 19.81 yards
Formula- (length*width*4 / fabric width /36+ wastage %)*12 (36 inches = 1 yard)
8. Exp- A T-shirt with chest 36 cm, Body length 60 cm, sleeve length 23 cm, Half armhole 27 cm , fabric's GSM 200, figure out it's fabric consumption in kgs/dzn?
Answer- [{(46*60) + (23*54)} * 2/ 200 / 10000000 +5%] *12 = 2 kgs
Formula- [{(chest* length) + (sleeve length * full armhole)} * 2 * GSM+ wastage %]* 12
9. Exp- A T-shirt with chest 18 inches , Body length 24 inches, Sleeve length 9 inches, Half armhole 10 inches, fabric width 48 inches, find out it's fabric consumption in yards/ dozen?
Answer- [{(18*24) +(9*20)} *2 / 48 / 36 +5%} *12] = 8.95 yards
Formula-[{(chest * length) + (sleeve length * full armhole)} * 2 / fabric width / 36 + wastage%] *12
The photo below shows you a pant's Length & width.
Note: A shirt or pant with more parts like collar,pocket,cuff etc. then we've to figure out consumption of each parts separateiy,and finally we need add all consumption together. One more important thing, I didn't mention sewing allowance during fabric consumption of product. You have to add sewing allowance with each measurement point during fabric consumption.
10. Exp- Suppose, we've made a market of 50 pcs shirts to cut fabrics. we're market length 7 yards 4 inches, marker width 60 inches, fabric GSM 180,now figure out Marker consumption & fabric consumption in Dozen?
Answer- Marker consumption: (7* 36 + 4) * 60 * 180 / 1550000 = 1.78 KGs. you see, firstly I've converted marker length into inches (7 * 36 + 4) as 36 inches = 1 yard.
Formula- marker length * marker width * GSM / 1550000
Fabric Consumption in dozen: ( 7 * 36 +4) * 60 * 180 / 1550000 / 5 * 12 = 4.28 kgs. Formula: marker consumption / pcs * 12
so, we see
K.G= length * width * GSM / 1550000
Or, Length = K.G * 1550000 / width / GSM
Or, Width = KG *1550000 / length /GSM
Or, GSM= KG * 1550000 /length / width ()please add wastage minimum 5 % with all outcomes)
6.Exp-A pant with Length 100 cm, Width 30 cm, GSM 210, Figure out it's fabric consumption in KGs/dzn? (1 dozen = KGs?)
Answer- 100*30*4*210 / 10000000 + 5% *12= 3.18 Kgs.

7. Exp- A pant of length 40 inches, width 12 inches , you have a fabric of width 34 inches, find out 12 (dozen) pant's fabric consumption into yards?
Answer- (40*12*4/34/36+5%)*12 = 19.81 yards
Formula- (length*width*4 / fabric width /36+ wastage %)*12 (36 inches = 1 yard)
8. Exp- A T-shirt with chest 36 cm, Body length 60 cm, sleeve length 23 cm, Half armhole 27 cm , fabric's GSM 200, figure out it's fabric consumption in kgs/dzn?
Answer- [{(46*60) + (23*54)} * 2/ 200 / 10000000 +5%] *12 = 2 kgs
Formula- [{(chest* length) + (sleeve length * full armhole)} * 2 * GSM+ wastage %]* 12
9. Exp- A T-shirt with chest 18 inches , Body length 24 inches, Sleeve length 9 inches, Half armhole 10 inches, fabric width 48 inches, find out it's fabric consumption in yards/ dozen?
Answer- [{(18*24) +(9*20)} *2 / 48 / 36 +5%} *12] = 8.95 yards
Formula-[{(chest * length) + (sleeve length * full armhole)} * 2 / fabric width / 36 + wastage%] *12

Or, Width = KG *1550000 / length /GSM
Or, GSM= KG * 1550000 /length / width ()please add wastage minimum 5 % with all outcomes)
