T-shirt fabric weights: lightweight to heavyweight
Australian buying guides
GSM measures fabric mass per square metre. It helps compare tees, but fit, fibre, knit and finish also affect how a garment feels. Choose for the person and purpose, rather than the largest number.

Check the current product page for composition, colours and measurements. These examples show different garments, not a controlled test of weight alone.
Start with use and climate
For an outdoor summer event, consider comfort, activity and the design coverage as well as fabric weight. For a brand or club merchandise drop, drape and a particular silhouette may matter more. A heavy cotton shirt is not automatically the right training shirt.
Use cotton versus performance fabrics when the wearer will exercise in the shirt. Consider a sample when the fabric feel is central to the purchase.
Fit and printing change the result
Two 260 GSM tees can have different lengths, sleeve shapes and chest measurements. Compare the selected size charts in cm, and measure a garment you already like. A printed area also has its own feel; a large solid graphic can cover more fabric than a small logo.
Read the group sizing guide and placement guide before ordering for other people.
Use a separate comparison for hoodies
T-shirt and hoodie weights should not be treated as one universal quality scale. Fleece, lining and garment construction change the comparison. Our hoodie GSM guide explains the heavier layers in the range.
For a group enquiry, send the purpose, budget range and preferred fit. We can help narrow the tee selection before you request a bulk printed-shirt quote.
Common questions
Is 300 GSM always better than 180 GSM?
No. It is heavier fabric, but the better choice depends on intended use, fit, fibre, construction and personal preference.
Does GSM tell me how much the whole shirt weighs?
No. GSM describes the fabric per square metre. Finished garment weight also depends on its dimensions, construction and other components.
