Fabric Weight Converter & Calculator

Thickness / Standard Weight
g/m²(gsm)
oz/yd²

Total Weight / Linear Weight
fabric width
fabric length

Enter oz/yd² or g/m²(gsm) to convert each other;
Enter fabric width and length to calculate the fabric total weight.

The fabric weight converter can convert grams per square meter (gsm) to ounces per square yard (oz/yd²), or vice versa, ounces per square yard to grams per square meter. It can also calculate the total weight of the fabric.

How to use the fabric weight converter

To convert GSM to oz/yd²: Enter the value in the GSM field.
To convert oz/yd² to GSM: Enter the value in the oz/yd² field.
To calculate total fabric weight: Enter the fabric's width and length.

Convert GSM and oz/yd²

GSM aka g/m² = grams per square meter
oz/yd2 = ounces per yard squared
1 gram = 0.03527 ounces (Convert grams to ounces)
1 lb = 16 oz = 453.59237 grams (Convert pounds(lbs) to grams(g))
1 inch = 2.54 cm (Convert inch to cm)
1 yd = 36 inches = 0.9144 m = 91.44 cm (Convert yards to meters)

Conversion Formulas

There is an easy way to convert gsm to oz/yd².
Divide the gsm by 33.906 - really that is all.
To determine gsm from oz/yd2 you do the reverse - multiple by 33.906.

If it helps, this is what the formulas are based upon:

1 oz = 28.3495231 grams (oz to grams converter)
1 yard = 0.9144 meters (yards to meters converter)
1 yard squared = 0.9144 m x 0.9144 m = 0.83612736 meters squared (convert square meters to square yards)

Therefore

1 oz/yd² = 28.3495231g/.83612736 m² = 33.90574744 g/m2
Rounded up to three decimal places it is 33.906

Question : If a fabric is 5.5oz/sq yard, how many the weight is in grams/sq meter ?
Answer : 5.5 oz/sqyd x 33.906 = 186.483 gm/sqm

Fabric Weight Conversion Chart

How much does a t-shirt weigh?

The weight of a t-shirt depends heavily on its size and the fabric's GSM (Grams per Square Meter). Generally, a standard adult t-shirt weighs anywhere from 130 to 200 grams (approx. 4.5 to 7 oz).

Different materials and printing methods also play a role in the final weight and feel of the shirt:

Classic & Breathable: If you prefer a soft, comfortable feel for everyday wear, 100% cotton is the best choice. It usually features a medium fabric weight (around 160-180 GSM). You can easily create your own design with our high-quality Custom Pure Cotton T-shirts.
Vibrant & Eye-Catching: Looking for artwork that covers the entire garment? Sublimation printing on polyester blends is the way to go. Bring your boldest creative ideas to life with our All-Over Print T-shirts.
