Woven fabric consumption formula

Learn Apparel Merchandising, Learn Fashion design.
Before calculate the woven fabric consumption, you must need the followings information as mentioned below:

1) Measurement chart with technical spec.
2) Style Description.
3) Fabric Description.
4) Fabrics width/weight.
5) Washing shrinkage if any.

This formula is as under :
Formula = Length  X Width  / Fab width X Fab Unit

Here,
Length = length of the specific parts + allowance

Width  = width  of the specific parts + allowance

Fab width = Fabric width ( after considering the shrinkage
allowance).
Say, fabric width is 45″ & the shrinkage
allowance is 1″, Then the Fabric width will
be (45″-1″) = 44″ in the formula.

Fab unit = Fabric calculation unit, here it will be 36 because
we are going to calculate the consumption in
Yards.

Now we will calculate the consumption of a Shirt (front part)

Center front length  = 32″+1″ (Sewing allowance) = 33″
Width (Chest)        = 24″ + 1″ (Sewing allowance) + 3″
Pleat.W (1.5X2)  = 28″

= Length  X Width  / Fab width X Fab Unit
= 33″ X 28″ /  44″ X 36″
= 924″ / 1584″
= 0.5833333

= 0.59 Yards. (for front part)

    Hi Bipul,
    can you pls advise the woven bottom consumption details formula. i'm confused on several way of making consumption as i knew the below like as;

    Consumption example:
    Inseam = 58
    Back rise= 27
    ————————————-
    = 0000
    (+) W/b 4×2+allowance = 12
    ————————————–
    = 0000 ÷ 2.54(convert to inch) = result 40”
    Thigh = 20 × 4(part) =80 ÷ 2.54(convert to inch) = result 37”

    Total: L × W= ans ÷ 36 yds ÷ 56/58//60 (fab width) × 12 dzs × extra 10% = result Fab consumption

    Reply of Mr.Tanin

    Dear Mr. Tanin
    First you asked for Woven bottom garments Details formula & we think the formula given above by Bipul bhai is the unique formula ,based on that i will explain details formula .But before that pls find the answer of you question last part

    In your Consumption example:
    Inseam = 58 cm
    Back rise= 27 cm (excluding west band )
    ————————————-
    length = 85 cm
    (+) W/b 4 cm x2 part ( inside & out side )+allowance 4 cm= 12 cm
    ————————————–
    = 97 cm ÷ 2.54(convert to inch) = result not 40” it will be 38.19 we can consider it as, Total Length is 38 inch.

    Thigh = ½ thai of one leg 20cm × 4(part.. as Two leg has 4 pc ½ Thai ) =80 cm ÷ 2.54(convert to inch) = result not 37” it will be 31.496 we can consider it 32 inch

    Now you can calculate it using your below formula
    Total: L × W= ans ÷ 36 yds ( it will be inch ) ÷ 56/58//60 ( consider any one of this fab width ) × 12 dzs( it will be Pcs ) ×( not multiply X , Pls add the percentage + ) extra 10% = result Fab consumption….

    Total: L = 38 inch × W = 32 inch = ans 1216 squre inch ÷ 36 inch ÷ say it is 56 inch (fab width) × 12 pcs + extra(wastage as per nature of fabric ) 10% = result Fab consumption

    Total: 1216 square inch ÷ ( we can calculate it like this 36 inch X 56 inch (fab width)= total × 12 pcs + extra(wastage as per nature of fabric ) 10% = result Fab consumption

    Total: 1216 square inch ÷ 2016 square inch = 0.60 yds per pc × 12 pcs = 7.24 yds /doz + extra 10% .72 yds = final result for Fab consumption is 7.96 (7.24+.72) Yds /Dz .

    Hope you are clear now ..

    First of all I'd like to thank you very much for your reply as well for below correction….

    1) yes back rise excl band.
    2) thigh part to be as per your consumption 32 inch.
    3) Extra percentage will not multiply s/be (+).

    Can you pls advise me the actual formula for woven fabrics consumption with details example.

    Thanks/ Tanin

    Dear Bipul Vhai

    Seeking for you kind permission, would you pls allow me to share in details about the “Woven bottom consumption ” for those who send request regarding this issue in your blog

    (Rest part of previous Discation )

    For batter understanding we can follow below Example :

    Say 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 X12 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 X 2052 square inch + 5% Wastage X12 Pcs

    = 1.61 Yds +0.08(Wastage)= 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

    Caution :- Friends pls keep in mind that as market is so competitive now a days , so when a buyer ask for a price quotation no matter how experience you are but pls don’t take any risk. Always figure out practical consumption by the help of your Pattern master & believe me that will be the perfect for your organization.

    Thanking you on be half of Mr.Bipul

    Seeking for you kind permission, would you pls allow me to share in details about the “Woven bottom consumption ” for those who send request regarding this issue in your blog

    ( For those only who need this )

    In Apparel sector there are 2 types of Merchandise, One is Woven merchandise ( Such as Shirt , Pant , Blouse etc ) & the other one is Knit merchandise ( Circular Knit :- Tee shirt , Polo shirt ,Fashion knit :- Sweater Etc ) . Merchandiser is the key person of this sector, who communicates with Buyer or Buying house to get an Order. The procedure of getting an order from a buyer, merchandiser got an inquiry directly from a Buyer or from a Buying house. In that inquiry buyer ask for price of his desired garments, it may be in Woven fabric or In Knit fabric. For quote a price, merchandiser must calculate fabric consumption first, coz fabric price cover more than 60 % of that quoted Price.

    As a Merchandiser, for any type of Garments Consumption calculation, first we have to know what type of garments we are going to make. For that, we need to know the specific parts name & the measurement of that particular garments parts. Measurement may be in inch or in centimeter (Measurement in Inch for American order & Centimeter for European order). That’s need to calculate consumption. For accurate measurement we need to make a “Paper pattern “ or “CAD pattern “ first . pattern is the sketch combination of different parts of a garments .

    We all know every part of garments have its LENGTH & WIDTH measurement. Basically on woven garments, we calculate the consumption in Yard/ Doz (2.54 Cm= 1 inch & 36 inch = 1 Yds,). In that case we also need to know the Width of that particular fabric which we are going to use. Now we will calculate each of the separate part based on this Length & Width. to have the total consumption, for this we can use Separate part formula as below:-

    (LENGTH X WIDTH) X Number of Parts pcs or Panels / Fabric Width (Pls consider suitable sewing allowance with each length & width for each application.)

    After calculate the consumption of all t part this way, now we will add all that separate parts consumption tighter ,than we will add wastage percentage based on the fabric nature which we are going to use for that particular garments.

    We can also workout the consumption of a bottom item by using the below “Solid formula for calculate consumption"

    Solid formula for calculate required Fabric consumption / Doz :-

    (Total LENGTH X Total WIDTH ) X Number of Parts pcs or Panels / Fabric Width X36 inch = (Total + 5 % Wastage) X 12 Pcs= Result in ..Yds / Doz .

    In here

    Total Length = Inseam (Length) + Back rise (Including West band ) + Sewing Allowance (S.A )
    Total Width = ½ Thai + Sewing Allowance

    ** we can also calculate
    ( A) Back rise without West band
    ( B) Parts pcs = there is 4 pcs of 1/2 Thigh as a bottom item has 2 Leg
    (C) We multiply the total measurement with 36 inch to make the result in yds which was in inch before
    ( D) For wastage percentage the calculation depends on the nature of fabric shrinkage or elongation on wash & others effect
    **{We calculate this wastage percentage lowest ( 5 % ) on Regular fabric but for Stretch fabric it may stand up to 25 % based on the nature of the Fabric}

    To be continue

  17. tamim says:

    Correction on above calculation :-

    Pls note that there is a typing error on………….

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

    (Type mistake in the below line )
    = 3300 square inch X 2052 square inch + 5% Wastage X12 Pcs

    It will be
    =( 3300 square inch / 2052 square inch )+ 5% Wastage X12 Pcs
    = 1.61 Yds +0.08(Wastage)= 1.69 Yds X12 Pcs = 20.28 Yds /Doz.

    I am sorry for this inconvenience

  18. Tanin says:

    Dear Tamim bai,

    well deserve it. many many thanks for your details formula.
    all are clear. by the by you calculated in consumption in inch if the measurement are in CM than should we convert into inch or do you other idea. pls advise.
    yes for the correct consumption everyone must have to make the pattern mark.

    Thanks you very much. as well to Bipul bai for making such a useful blog.

  22. I'am not more expert but i can try to help u.You first take every pocket length and width and then put their into following formula……
    Pocket=[{(Length+allowance+shrinkage if required)*(width+allowance+shrinkage if required)}*no of parts/fabric width*12/36+wastage%]
    All measurement puts sequence on a normal calculator.I think u get accurate consumption…brother…shajol
