180 GSM vs 240 GSM T-Shirts: Which Weight Should Your Brand Choose?

180 GSM vs 240 GSM T-Shirts: Brand Decision Guide

GSM (grams per square metre) is the textile industry's fabric weight measurement. For T-shirts, 180 GSM and 240 GSM are the two most common premium tiers. Here's how they differ.

180 GSM: The Premium Retail Standard

180 GSM is the sweet-spot weight for premium retail T-shirts — heavy enough to feel quality, light enough for year-round wear and broad market appeal.

Feel: Substantial but not heavy. Comfortable in 60-85°F (15-29°C).

Drape: Slight structure, not floppy.

Brand tier: Premium retail ($30-60 retail).

Best use: Year-round retail, brand staples, mass-market premium.

240 GSM: The Heavyweight Streetwear Tier

240 GSM is heavyweight territory — substantially heavier than typical retail T-shirts and noticeably weightier than 180 GSM.

Feel: Heavy, substantial, premium streetwear.

Drape: Strong structure, holds shape, drops with weight (essential for boxy oversized fits).

Brand tier: Premium streetwear ($60-150 retail).

Best use: Oversized streetwear, capsule drops, fashion-forward brands.
