GSM (grams per square metre) is the single most useful number on a ream of copy paper. It tells you how heavy — and how premium — a sheet feels, how opaque it is, and how it behaves in high-speed printers. At WB PAPER FACTORY we manufacture A4 in 70, 75 and 80 GSM, and choosing well can save you money without sacrificing quality.
70 GSM — efficient everyday printing
Lightweight and cost-effective, 70 GSM is ideal for high-volume internal documents, drafts, and back-office printing where cost-per-page matters most. You get more sheets per kilo and smooth, jam-free feeding.
75 GSM — the balanced workhorse
A popular middle ground: noticeably crisper than 70 GSM with better opacity for double-sided printing, yet still economical for daily office use.
80 GSM — premium and professional
Heavier, brighter and more opaque, 80 GSM is the choice for client-facing documents, reports, and presentations. It resists show-through and feels substantial in the hand.
Our tip: standardise on 75 GSM for general use and keep 80 GSM on hand for anything that leaves the building. Need bulk pricing across weights? Request a quote.
