### Calculate the consumption of knit garments

Learn Apparel Merchandising, Learn Fashion design.
Dear All,
For calculating the consumption of your knit garments pls follow the below instruction. The following information you need at first, as listed below:

(During the consumption pls used measurement of middle size for calculation or used the size which have most of the qty. If the style have 6 sizes then used size number 04 for consumption. Here we will consider the size: "L" for calculate the consumption)

i. Body length of the garments in cm. Say it is - 73 cm

ii. Sleeve length of the garments in cm. Say it is - 19.5 cm

iii. Approximate sewing allowance at body hem, shoulder joint, sleeve hem & armhole joint (in cm). Say it is - 10 cm

iv. Chest width (1/2) in cm. Say it is - 52 cm

v. Approximate sewing allowance at both side seam (in cm). Say it is - 4 cm

vi. Fabric GSM (finish)Say it is - 160 gsm

vii. Approximate fabric wastage in various stage. Say it is - 10%

(In this regards pls note that, fabric wastage depend on how many additional elements the garments have,which may changed in any time.If the garments has rotary print, enzyme stone wash etc than the fabric wastage will be more than normal wastage)

If you already have all the above information then,now just put the following information and get the fabric consumption.http://knitgarmentsconsumption.blogspot.com/ otherwise you can follow the below rules

Rules:
{(B/length + S/length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage

= {(73 + 19.5 + 10) X (52 + 4)} X 2 X 160 X 12 / 10000000 + 10%

=  (102.5 X 56) X 2 X 160 X 12 / 10000000 + 10%

= 5740 X 2 X 160 X 12 /10000000 +10%

= 22041600 / 10000000 + 10%

= 2.20416 + 10 %

= 2.424576

= 2.43 kg per dozen. (Consumption)

Hope everything is now clear to all.

Thanks

24. Hi Bipul,

Bt hv few queries, pls adv...
Why width nt been considered? Wat width do we consider? Why is it calculated by 12/10000000? why the final answer mention as consumption per dozen? hw can we calculate on per pc basis?

25. nice site....

26. dear mr bipul bai
can you tell me how to calculate consumption and costing of a Basic polo shirt and basic tank-top.
i am at learning stage.pls boss help me

27. need polo shirt consumption

28. Frequently people ask why use 10000000 in consumption formula??
The basic formula per piece is L x W x 2/10000*GSM/1000
L= Body & sleeve length with allowance
W= Chest measurement with allowance
2= as each garment have two part
10000= is a big question?? see we get fabric area by using basic formula but we need to know how much fabric is required in kgs??
Usually we know GSM (grams per square meter) so we've to convert the fabric into square meter. 1m=100cm, 1sqr meter=10000 cm (100cm x 100cm), so divide fabric area by 10000. so now we get fabric in Sqr meter.
*GSM= multiplying by GSM we get total grams of fabric
1000= why 1000? now its simple. we have total grams of fabric and dividing 1000 we get kgs. 1kg=1000 gram.

People commonly divide by 100000000 (10000x1000) to get fabric in kgs.

hope it make you clear-pls let me ask if anything unclear.
thanks

2. why sleeve width{armhole straight} is not added with chest measurement for fabric consumption.tell me anybody urgently ,thanks>01845878419

29. Hi,

Really nice effort!

But sleeve width is dropped! Sleeve consumption should be added with body consumption separately for accurate consumption. As per formula sleeve length is added with body length. That is, body length is now =73+19.5=92.5cm. (Probably that is why sleeve width is not added with chest measurement for balance!).

Thank you all.

Each garment that is purchased and worn by the customer represents a countless hours of planning, preparation and execution to arrive at the finished product.
