Understanding panna, quality and GSM in wholesale fabric

If you've ever heard a supplier say "12kg" or "17kg" fabric and felt confused about what that actually means, you're not alone. These numbers only make real sense once you connect them to two other things: panna (width) and GSM (weight/thickness). Here's a simple breakdown.

What is "panna"?

Panna simply means the width of the fabric roll, usually measured in inches (like 42", 44", 56", or 58"). It tells you how much fabric you get across, not how long the roll is.

Why it matters: a wider panna lets you cut larger pieces (like a full kurti or dress panel) from a single meter, which can mean less joining. A narrower panna (chotta panna) works well for smaller pattern pieces, trims, dupattas, and certain garment styles where a wider width isn't needed — and it's often priced accordingly.

Quick tip: Always ask "what panna?" alongside the price, and match it to what you're actually cutting — the right panna depends on your product, not just the width number.

What does "12kg" or "17kg" actually mean?

This number refers to the weight of one roll of fabric (like a "thaan"), not the weight of a single meter. So when a supplier says "17kg fabric," they mean the roll you're buying weighs 17kg in total — not that each meter weighs 17kg.

This is where confusion often happens. Two rolls both called "12kg" can still feel different in hand — because the actual per-meter weight depends on both the roll weight and the panna (width) together. A 12kg roll in a narrow panna will feel heavier and thicker per meter than the same 12kg roll in a wider panna, since the same weight is spread across less width.

What is GSM, and how is it different?

GSM stands for Grams per Square Meter — it's a direct measure of fabric thickness and quality, independent of roll size. The higher the GSM, the thicker, heavier, and often more durable the fabric feels.

• Lower GSM (around 100–120): light, breathable, good for summer wear or linings.
• Mid GSM (around 130–150): balanced, common for kurtis, tops, and everyday wear.
• Higher GSM (160 GSM and above): thicker, more premium feel, better drape and durability.

Unlike "12kg" or "17kg" (which describe the whole roll), GSM tells you the actual quality of the fabric itself, per square meter — which is why it's a more reliable way to compare fabrics from different suppliers.

How panna, weight and GSM connect to per-meter cost

• Panna (width) tells you how much usable fabric you get across.
• Roll weight (12kg/17kg etc.) tells you the total quantity in that roll.
• GSM tells you the actual thickness/quality per square meter.

Together, these three decide the real cost per meter — not just the quoted price.

For example, two fabrics quoted at the same price per meter can still work out differently once you factor in panna and GSM — a wider panna with the same GSM will usually give you more usable fabric per meter, while a narrower panna at a lower price can still be the smarter choice if your cutting pattern doesn't need the extra width.

Simple checklist before you buy

• Ask for the panna (width) — not just the roll weight.
• Ask for the GSM, especially if you're comparing multiple suppliers.
• Calculate cost per meter based on GSM and panna, not just the roll price.
• Don't assume "12kg" or "17kg" alone tells you about quality — it only tells you the roll's total weight.

The bottom line

Panna, roll weight, and GSM all work together to determine the real value of a fabric. Once you understand how these three connect, comparing suppliers and prices becomes much easier — and you'll avoid paying for what looks like a good deal but isn't.
