How Much Fabric is Required Making T-Shirt and Polo Shirt

I have been asked the following question:

“How many meter fabric makes a t-shirt round neck, polo t-shirts”
See my answer below.

This seems a very simple question. I can provide you with some consumption figures for T-shirts that I made earlier. Like you may need the fabric of 160 grams or 190 grams for making one t-shirt.

But this might not be true for your case, as you might be using a different fabric. If you use fabric of higher GSM you will be required more (in Kg) fabric compared to low GSM fabric. Fabric requirement for the knitted garment is measured considering few parameters. These parameters are listed below.

  • Garment specification or measurement - length and width of all T-shirt components 
  • Fabric width – to get an idea of how many patterns can be placed side by side, how much fabric remains unused after placing garment patterns 
  • Fabric GSM – Fabric weight per square meter 
Sometimes fabric consumption also depends on fabric patterns. Like if you need to match stripes and checks in garment, consumption may increase.

Knitted Fabric

You are also asking for fabric requirement in meters.

In practice, requirement of knitted fabric is measured in grams (or Kilograms) instead of in meter. If you need to know fabric length, you can find it using formula and after having data for fabric consumption, fabric width and fabric weight (GSM).

Why not in meters? Read the following explanation,

T-shirts and Polo shirts are made of knitted fabrics. Knitted fabrics are easily stretchable in nature. Because the knitted fabric is manufactured by loop formation. So to avoid variation in length, knitted fabrics are purchased in weight (Kilogram). Based on the manufacturing process of fabrics, fabrics are classified into two categories - Woven Fabric and Knitted fabrics. On the other hand-woven fabrics are purchased in meters.

As said above, know about garment size and find fabric area required for a garment. Then multiply the area by fabric GSM to calculate fabric requirement (Assume that fabric width is fit to patterns and no side wastage). Then add wastage to get actual fabric requirement per garment.

Read this post to learn how to calculate fabric consumption for a T-shirt.

The same guideline can be used for calculating fabric consumption for Polo shirt. Just you need to add fabric front placket components and find the weight of collar and sleeve ribs separately.
