Short answer: most product catalogues read best on 128–170 gsm coated silk or matte text, with a 250–300 gsm cover when the piece runs past 64 pages. Pick text weight by page count and shipping weight first; pick the coating by how the product photography must read.

A catalogue lives or dies on paper choice long before anyone judges the design, because paper drives three budgets at once: the print bill, the postage or freight bill, and how the products actually look on the page. This guide sets out the decisions in the order a procurement team should make them.
Text weight should follow page count, because a heavy sheet on a long catalogue turns the piece into a brick that costs more to ship than to print. Grammage is measured in grams per square metre under ISO 536:2019, the paper and board test method most mill specifications quote. Typical working ranges (illustrative, per catalogue format):
| Catalogue type | Typical text | Typical cover | Notes |
|---|---|---|---|
| A4, 24–48 pp (saddle stitched) | 128–157 gsm coated | Same stock as text (self-cover) | Self-cover keeps the quote simple at short lengths |
| A4, 64–120 pp (perfect bound) | 128–157 gsm coated | 250–300 gsm | Cover needs the extra stiffness once the spine takes glue |
| A4 annual report, 80+ pp | 150–170 gsm matte | 300–350 gsm | Heavier text suits institutional reading and longevity |
| A5 / DL trade catalogue | 113–150 gsm coated | 250–300 gsm | Lighter sheets offset the smaller trim in mailing weight |
| Lookbook, image-led | 150–200 gsm matte | 300–350 gsm | Weight buys presence; check the freight bill before committing |
A concrete feel for the numbers: a 48-page A4 catalogue on 150 gsm coated text weighs roughly 225 g per copy before the cover (illustrative arithmetic — 24 A4 sheets at about 9.4 g each). At 10,000 copies that is 2.25 tonnes of paper before packing, which is why the weight column on your quote deserves as much attention as the unit price.
Coated silk is the default for product catalogues because the coating holds ink on the surface, so mid-tone photography of products stays punchy and fine captions stay sharp. Coated matte trades a little snap for a calmer, glare-free page that photographs well under showroom lighting. Uncoated stock scatters light through the fibre, which lifts shadows and desaturates colour — a real constraint if the catalogue must match product colour claims. Whatever you choose, the press must be calibrated and profiled; we run the G7 gray-balance process Idealliance documents for aligning devices, substrates and inks to a common visual appearance, executed on our floor without third-party certification claims, and we match the press to a hard-copy proof of your own files.
Cover decisions follow the binding, and the binding follows the page count. Saddle stitching suits catalogues up to roughly 64 pages; beyond that the spine bulges and perfect binding with a glued spine takes over — at which point a 250–300 gsm cover is not a luxury but a structural necessity. Creasing matters too: sheets above about 170 gsm crack along a fold unless the fold is scored first, which is why heavier self-cover designs should be quoted with scoring included. For image-led lookbooks the paper logic is the same as art books — see our guide to art and photography book paper and binding, and for the fold styles themselves see gate, roll and Z-folds.
Freight is where catalogue paper specs quietly get expensive. Exported print is invoiced by volume, not value, so a heavier stock multiplies both the kilograms and the carton cube. Three practical rules: choose the lightest text weight your photography tolerates; ask the printer to quote the same file on two stocks so the unit-cost delta is visible; and remember that air freight on a heavy annual report can cost more than the printing. Distributors moving EU-bound catalogue stock should also read our explainer on HS codes for books, catalogues and packaging before booking freight. For archival pieces intended to last decades, ask mills for a permanence stock made to ISO 9706, the standard for permanent paper.
A quotable catalogue spec needs five lines: trim size, page count, text stock (name the gsm and coating), cover stock, and binding. Add finish — matte laminate on the cover is the common spend — and the fibre ask: we print on request with FSC-certified papers and supply the chain-of-custody paperwork with the order documents. If vocabulary on the quote sheet is the obstacle, our printing glossary for buyers covers the terms in the order a project meets them.
