Brochure Printing Specs: What Paper Weight & GSM is Best for Sales Materials?
Founder, RoboSouls • •
Executive Summary
For premium B2B corporate brochures, a common specification is a 300 GSM–350 GSM art card cover, creased and laminated, paired with 170 GSM matte or gloss art paper for the inner pages. This combination gives a substantial hand-feel, keeps show-through low on most designs, and reproduces images and architectural renders cleanly.
1. What is GSM and Why Does It Matter for Print?
GSM stands for 'Grams per Square Metre' — it measures the weight of a sheet, not its thickness. Within the same paper type, a higher GSM usually means a thicker and more opaque sheet, but two stocks at the same GSM can differ noticeably in calliper and opacity: coating adds weight without adding much height. Ask for calliper when thickness is what matters, and discuss opacity when both sides of a page carry heavy images. Paper weight is one of the first things a prospective client notices when holding a brochure or sales kit.

2. The Art Paper Hierarchy: 130 GSM vs. 170 GSM vs. 300 GSM
Corporate sales materials are usually printed on double-coated art paper, matte or gloss. Page count and binding narrow the choice. On a saddle-stitched (stapled) brochure, heavy inner pages increase creep and bulk at the spine as the page count rises. A perfect-bound (glued spine) book carries heavier stock comfortably, but it never opens fully flat.
| Paper Weight | Common Use Case | Perceived Perception & Hand-feel |
|---|---|---|
| 90–115 GSM | High-volume flyers, mail drop leaflets, envelopes | Lightweight, cost-effective, disposable feel |
| 130 GSM | Inner pages of 64+ page catalogs, standard product flyers | Standard print weight, folds flat easily, good opacity |
| 170 GSM | Inner pages of premium brochures, real estate sales kits | Luxury hand-feel, thick pages, low show-through on most designs |
| 250 GSM | Covers of saddle-stitched catalogs, premium presentation folders | Stiff card, excellent fold memory, highly durable |
| 300–350 GSM | Brochure covers, premium business cards, luxury tags | Heavy-duty board, substantial presence, premium weight |

Key Takeaway
Specify a 300 GSM or 350 GSM cover board, crease it before folding, and laminate it — soft-touch for feel, matte for durability. Add spot UV over the logo for contrast.
A brochure's cover is its handshake. At RoboSouls, we advise corporate and real estate clients to use a 300 GSM or 350 GSM single-ply card cover. A heavy cover folded without creasing will crack along the spine, so the cover is creased before it is folded, and a thin matte or soft-touch (velvet) laminate film holds the surface fibres together across the fold, which matters most on dark covers. The laminate also eliminates glare and creates a tactile, premium surface. Applying a spot UV glossy clear coat over your logo creates a striking glossy contrast on a velvet matte backdrop.

Summary Overview
B2B procurement runs on trust, and a flimsy brochure undermines a serious proposal before anyone reads it. A 170 GSM inner and a 300 GSM cover, creased and laminated, gives a sales kit the substance its content deserves.
