GSM and Paper Weight Explained — The Simple Guide

You'll see "GSM" on every Indian print order — paper weight in grams per square metre. Higher GSM means heavier, stiffer paper. Lower GSM means lighter, more flexible. But the practical question is: which GSM for which use? Here's the simple cheatsheet.

The GSM range chart

• 60–80 GSM: regular notebook / newspaper paper. Light, see-through. Not for premium use.
• 80–100 GSM: standard office printer paper. Letters, internal documents.
• 120–170 GSM: flyer / brochure paper. Light enough to fold, heavy enough to feel like marketing material.
• 200–250 GSM: postcard / heavyweight brochure / certificate paper. Stiff but still foldable with scoring.
• 250–300 GSM: business card / tent card / dangler weight. Self-standing if creased.
• 300–350 GSM: premium business cards, premium tent cards. Heavy and substantial.
• 350–400 GSM: ultra-premium business cards, packaging. Rigid card stock.
• 400+ GSM: approaching cardboard. Used for book covers, packaging, premium tags.

The matching rule

Match GSM to use:

• Things people read (books, brochures): 75–170 GSM
• Things people hold briefly (flyers, posters): 130–250 GSM
• Things people keep (business cards, certificates): 300–400 GSM
• Things that need to stand on their own (tent cards, danglers): 300+ GSM
• Things that need to fold (brochures): 130–170 GSM (heavier paper cracks when folded)

The cost-vs-perceived-value sweet spot

Paper price increases roughly linearly with weight. But perceived quality has diminishing returns:

• The jump from 100 to 170 GSM brochure paper: noticeable
• The jump from 170 to 250 GSM: noticeable but less dramatic
• The jump from 300 to 350 GSM business cards: noticeable
• The jump from 350 to 400 GSM: barely noticeable

The "premium" tier sweet spot is at 350 GSM for cards and 170 GSM for brochures. Going higher rarely earns its cost back in perceived quality.

What's not GSM

GSM is weight per area, not thickness. Different paper types of the same GSM can have different thicknesses — coated papers are denser (and thinner) than uncoated papers at the same weight. So 300 GSM uncoated card stock feels different from 300 GSM coated art card. For most purposes, the difference doesn't matter, but for very tactile uses (premium business cards), specify the paper type AND the GSM together.
