Knit T-Shirt Fabric Consumption Calculator Formula

Fabric consumption formula for t shirt can calculate in two formats: 1) Centimeter, 2) Inch.

Fabric consumption for t shirt in centimeter you have to divide the whole calculation by 10⁷ (100x100x1000). On the other hand, The t-shirt fabric calculation in inches required divided by 1550000 (39.37 x 39.37 x 1000).

Fabric consumption formula for t-shirt are as:

Formula For centimeter

i) T-Shirt Fabric Consumption = [(Body Length + Sleeve Length + Seam Allowance) x (½ Chest + Armhole + Seam Allowance) x 2 x GSM x 12 x Dozen]/ (100x100x1000)

ii) Total Fabric Consumption (with wastage%)= Fabric Consumption + Wastage and extra cutting% of Fabric Consumption

Formula For Inch

i) T-Shirt Fabric Consumption = [(Body Length + Sleeve Length + Seam Allowance) x (½ Chest + Armhole + Seam Allowance) x 2 x GSM x 12 x Dozen] / (39.37 x 39.37 x 1000)

ii) Total Fabric Consumption (with wastage%)= Fabric Consumption + Wastage and extra cutting% of Fabric Consumption

N.B.: Rest of the things such as trim fabric, bowing fabric, string, extra mesh fabric, decorative fabric, and other fabric consumption can calculate according to the tech pack.

Fabric Consumption Chart for T-Shirts

In Centimeters (cm)

In Inches

This chart shows the fabric consumption for T-Shirts in both centimeters and inches. The exact fabric consumption is calculated based on the provided measurements, and the total fabric consumption includes an additional percentage for wastage and extra cutting. The GSM (grams per square meter) and the number of dozens are also considered in these calculations.

How to calculate fabric consumption?

Step-by-Step Calculation Example

Let’s break down how to calculate fabric consumption for t-shirt an example. Suppose we are calculating in centimeters with the following details:

• Body Length: 70 cm
• Sleeve Length: 20 cm
• Seam Allowance: 1.5 cm
• ½ Chest: 25 cm
• Armhole: 8 cm
• GSM: 150
• Wastage and extra cutting%: 10%
• Dozen: 1

Step 1: Calculate Exact Fabric Consumption

Formula:
Exact Fabric Consumption (cm):
Exact Fabric Consumption = [(Body Length + Sleeve Length + Seam Allowance) x (½ Chest + Armhole + Seam Allowance) x 2 x GSM x 12 x Dozen] / (100 x 100 x 1000)

Calculation:
Exact Fabric Consumption = [(70 + 20 + 1.5) x (25 + 8 + 1.5) x 2 x 150 x 12 x 1] / (100 x 100 x 1000)
Exact Fabric Consumption = [(91.5 x 34.5 x 2 x 150 x 12)] / 1000000
Exact Fabric Consumption = 0.1134 Kg/Dozen

Step 2: Calculate Total Fabric Consumption

Formula:
Total Fabric Consumption (cm):
Total Fabric Consumption = Exact Fabric Consumption + (Wastage and extra cutting% of Exact Fabric Consumption)

Calculation:
Total Fabric Consumption = 0.1134 + (0.1134 x 0.10)
Total Fabric Consumption = 0.1134 + 0.01134 = 0.12474 Kg/Dozen

Example- 2:

Marker length = 168
Marker width = 76
GSM = 140
Consider 10% wastage.

Now calculate the fabric consumption of a t-shirt.

Formula = (Marker length × Marker width × GSM × 12)/ × 39.37 × 1000 × No. of garments
= 168× 76 × 140×12  /39.37 × 39.37 × 1000 × 6 + 10%
=2.31 kg/doz (2.31 × 10/100)
= 2.541 kg/ doz

Factors Affecting Fabric Consumption

1. T-Shirt Design and Size

The design and size of the t-shirt are primary factors. A more complex design with additional features like pockets, extra mesh fabric or embellishments will require more fabric. Similarly, larger sizes will consume more fabric compared to smaller sizes.

2. Fabric Type

Different fabrics have varying GSM, widths, weights, and stretch properties. For example, a stretchable single jersey fabric may require less material than a non-stretchable oxford fabric to achieve the same fit.

3. Garment Specifications

Details such as seam allowances, hem widths, and the presence of cuffs or collars stands also affect basic t-shirt fabric consumption. Precise measurement of these specifications ensures accurate consumption calculations.

4. Cutting and Wastage

Complete fabric cutting process and the amount of wastage determine the t shirt fabric consumption efficiency. Experience of cutting master and machine types are the key factors the efficiency. Boths can significantly reduce fabric waste. Fabric cutting and wastage can control from the pattern and marker layout optimization.

Importance of Fabric Consumption Calculation for T-Shirt

T-Shirt Fabric consumption refers to the amount of fabric required to produce a single unit of t-shirt. It is a crucial step to make costing in garments, BOM (Bill of Materials), CM (Cost of Making). Ultimately effect in the purchase order (PO)

1. Cost Efficiency: Accurate t-shirt fabric consumption calculation helps in determining the precise amount of fabric needed, reducing waste and optimizing material costs.
2. Price Quotation: Knowing the exact fabric requirement for basic t-shirt allows buyer and manufacturers to set competitive prices.
3. Inventory Management: Proper fabric consumption calculation ensures that the right amount of fabric is ordered and stocked. It prevents overstocking or stockouts.
4. Production Planning and Control: Helps in planning and scheduling production processes more efficiently by providing accurate material estimates.
