Fabric Consumption| Different method & formula use for calculating knit fabric consumption

Introduction: Consumption of fabric is defined as the average meter(s) (or kgs for knits) of fabric needed to make the garment. Fabric consumption is the most important factor in pricing a garment. So it must be calculated correctly otherwise profit will be decreased. We calculate fabric consumption by using different methods.

For fabric consumption in different methods, different types of formula we can be used:

1. Fabric Consumption by Single formula.
2. Fabric Consumption by Individual formula.
3. Fabric Consumption by marker planning formula.

1. Fabric Consumption by Single Formula:

   (Body length + Sleeve L. + Allowance) × (Half Chest + Allowance) × 2 × 12 × 160 × 1.10

= -------------------------------------------------------------------------------------------------------

                                                                       100×100×1000

2. Fabric Consumption by Individual formula:

Body part consumption;

    (Body length + Allowance) × (Half Chest + Allowance) × 2 × 12 × 160 × 1.10

= -------------------------------------------------------------------------------------------

                                                             100×100×1000

Sleeve Consumption;

    (Sleeve L. + Allowance) × (Sleeve width × 2 + Allowance) × 2 × 12 × 160 × 1.10

= ----------------------------------------------------------------------------------------------

                                                           100×100×1000

3. Fabric Consumption by marker planning formula:

    (Marker width in inch) × (Marker length in inch) × 12 × 160 × 1.10

= -----------------------------------------------------------------------------------------

                                                1550×1000×5

Standard body measurement

We used a short sleeve t-shirt measurement for understanding the difference between fabric consumption of different methods:

Fabric consumption for L size T-shirt:

Body Length: 72 Cm

1/2 Chest: 52 Cm

Sleeve Length: 22 Cm

Sleeve Width: 18 Cm

1. Fabric Consumption by Single Formula Method:

    (Body length + Sleeve L. + Allowance) × (Half Chest + Allowance) × 2 × 12 × 160

= ------------------------------------------------------------------------------------------------

                                                            100×100×1000

   (72+22+2) × (52+2) × 2 × 12 × 160 × 1.10

=--------------------------------------------------

                           100×100×1000

    96 × 54 × 2 × 12 × 160 × 1.10

= -----------------------------------

                100×100×1000

= 2.19 Kg/Dz

2. Fabric Consumption by Individual formula Method:

Body part consumption;

    (Body length + Allowance) × (Half Chest + Allowance) × 2 × 12 × 160 × 1.10

= ------------------------------------------------------------------------------------------

                                                            100×100×1000

    (72+2) × (52+2) × 2 × 12 × 160 × 1.10

=----------------------------------------------

                       100×100×1000

      74 × 54 × 2 × 12 × 160 × 1.10

= ------------------------------------

                100×100×1000

= 1.687 Kg/Dz

Sleeve Consumption;

   (Sleeve L. + Allowance) × (Sleeve width × 2 + Allowance) × 2 × 12 × 160 × 1.10
= --------------------------------------------------------------------------------------------

                                                       100×100×1000

    (22+2) × {(18 × 2) +2} × 2 × 12 × 160 × 1.10

=-----------------------------------------------------

                            100×100×1000

    24 × 38 × 2 × 12 × 160 × 1.10

= -----------------------------------

                100×100×1000

= 0.350 + 0.035

= 0.385 Kg/Dz

Total Consumption: 

Body length + Sleeve length 

= (1.687 + 0.385) Kg/Dz

= 2.072 Kg/ Dz

3. Fabric Consumption by marker planning formula:

    ( Marker width in Inch) × ( Marker length in Inch) × 12 × 160 × 1.10

= -----------------------------------------------------------------------------------    

                                                 1550×1000×5

     60 × 180 × 12 × 160 × 1.10

= ----------------------------------

              1550 × 1000×5

= 2.943 Kg/Dz

From the above method, we can find different fabric consumption for the same measurement as a T-shirt. So which method is more efficient for fabric consumption. from myself, marker planning or individual method is more efficient than the Single method for calculation.
