Paper weight is one of the first things people notice when they pick up a brochure — often before they read a single word. Too thin, and a premium company profile feels cheap. Too thick, and a tri-fold cracks at the folds and will not sit flat in a rack. This guide explains how to choose the best paper weight for brochures so your print feels right and performs well.
What does GSM mean?
GSM stands for grams per square metre. It measures how heavy one square metre of that paper would be. The higher the number, the thicker and stiffer the paper generally feels. For reference:
- 80 GSM — everyday office printer paper.
- 130–170 GSM — typical flyers, leaflets and folded brochures.
- 200–250 GSM — premium brochures and lighter covers.
- 300–400 GSM — business cards, postcards and heavy covers.
Thickness can vary slightly between papers of the same GSM depending on the coating and finish, so GSM is a guide rather than an exact measure of stiffness.
Recommended paper weights by brochure type
| Brochure type | Typical weight range | Why |
|---|---|---|
| Economy promotional brochure | Around 115–150 GSM | Keeps large runs economical; folds easily |
| Standard A4 tri-fold / bi-fold | Around 150–170 GSM | Good balance of quality feel and clean folding |
| Premium corporate brochure | Around 200–250 GSM | Substantial, professional feel; needs creasing before folding |
| Booklet inner pages | Around 115–170 GSM | Pages turn easily; booklet stays flat |
| Booklet cover | Around 250–350 GSM | Protects inner pages and adds durability |
Weight and folding: the key relationship
The heavier the paper, the more important creasing becomes. Creasing presses a groove into the paper before it is folded, so the fibres bend rather than break. Without it, heavier stocks — especially with dark, full-colour backgrounds — can crack along the fold, leaving a white line.
- For tri-folds and Z-folds, lighter-to-mid weights fold neatly and keep the brochure slim for racks and envelopes.
- For bi-folds (for example an A3 folded to A4), you can go heavier because there is only one fold.
Weight and finish work together
A gloss-coated 170 GSM sheet feels different from an uncoated 170 GSM sheet. Coated papers feel smoother and hold colour more vividly; uncoated papers feel more natural and absorb ink. Lamination adds stiffness and protection, making a brochure cover feel heavier than its GSM alone. For more on finishes, see our guide to gloss vs matte finish printing.
Match the paper to the purpose
Handed out once at an event or mall
A lighter weight keeps volume printing efficient and is perfectly adequate for a brochure that is read and kept for a short time. Our B4 economy brochures are designed for this kind of high-volume distribution.
Left in reception racks for weeks
Mid-weight paper resists curling and wear. Tri-folds finishing at DL size fit most brochure holders.
Company profiles, property launches, investor packs
Go heavier. A substantial brochure communicates quality before the reader turns the cover. Our premium A4 corporate brochure and A3 folded brochure suit these uses.
Mailed brochures
Balance feel with postage weight and envelope fit.
Sustainability considerations
Heavier isn't always better. If your audience values sustainability, a well-designed mid-weight brochure on responsibly sourced paper can make a stronger impression than an extra-thick one. Printing the right quantity — rather than over-ordering — is the most effective way to reduce waste.
Quick decision guide
- Is it a high-volume hand-out? Choose a lighter weight.
- Is it a standard tri-fold or bi-fold? Choose a mid weight.
- Is it a premium corporate or luxury piece? Choose a heavier weight with creasing and lamination.
- Is it a booklet? Choose a heavier cover with lighter inner pages.
Frequently asked questions
What is the most common brochure paper weight?
Mid-weight coated paper, roughly in the 150–170 GSM range, is common for standard folded brochures.
Can heavy paper be folded?
Yes, but it should be creased first to prevent cracking along the fold.
Should the cover be heavier than the inside pages?
For booklets and catalogues, yes. A heavier cover protects the pages and makes the booklet feel more substantial.
