Understanding GSM: What Fabric Weight Really Tells You
GSM stands for "grams per square metre" — it's a measurement of how much one square metre of a particular fabric weighs. Lower GSM means a lighter, often more breathable fabric. Higher GSM means more substance, usually more durability.
Why GSM Matters
When you're picking a fabric for a kurta meant for Indian summers, a 80–100 GSM cotton voile will feel airy and comfortable. But that same weight on a structured jacket would look limp and unfinished. Matching GSM to garment is one of the most underrated skills in fabric selection.
Common GSM Ranges by Fabric
- Voile / Mulmul: 60–90 GSM — sheer, summery, drapy
- Cambric / Poplin: 100–130 GSM — crisp, everyday wear
- Twill / Denim: 200–400 GSM — structured, durable
- Banarasi Silk: 150–200 GSM — body with sheen
- Linen (shirting): 130–180 GSM — breathable but substantial
How To Test GSM Without A Lab
Hold a single layer up to light. If you can read printed text through it easily, you're under 90 GSM. If light barely passes through, you're likely 150+ GSM. Not exact, but useful in a buying decision.
Final Tip
Always ask your supplier for the GSM upfront. A reputable manufacturer will know this number for every fabric they sell — at Dhvani, we list it on every product spec for exactly this reason.
