The Ultimate Guide to Printer Paper (Without the Jargon)

Let’s face it — printer paper isn’t exactly the most exciting office topic. But when you’re trying to print a report that doesn’t smudge, or a photo that doesn’t look like it was taken in 1999, suddenly that humble sheet of paper becomes a bit more important.

If you’ve ever found yourself staring blankly at a shelf of paper wondering what the difference is between all those packets, you’re not alone. Here’s your no-nonsense guide to printer paper — what to use, when to use it, and how to avoid buying the wrong thing.

Paper Sizes: It’s Not All A4

Most of us grab A4 without thinking (and for good reason — it’s the everyday hero of the office). But it’s not the only size out there:

• A4 – Standard size for everyday printing. Shop A4 Paper »

• A3 – Double the size of A4. Great for posters and big spreadsheets. Browse A3 Paper »

• A5 – Half the size of A4. Ideal for flyers, notebooks, or marketing handouts. See A5 Paper »

• Photo Sizes – Like 6x4", 7x5", etc. Perfect for home photo printing. Shop Photo Paper »

What Does GSM Mean?

GSM stands for grams per square metre — basically, how thick and heavy the paper is. Think of it like the difference between a sticky note and a birthday card.

• 75–90gsm – Standard office paper for everyday use

• 100–120gsm – Slightly heavier, more professional-looking

• 200–300gsm – Thick paper for posters or high-quality prints

• 300gsm+ – Card-style paper for invitations or premium prints

Not all paper is created equal. Here’s the lowdown:

• Matte – No shine. Great for printing text and documents

• Glossy – Shiny surface. Ideal for photos and colour-rich prints

• Silk/Satin – Smooth, professional finish without being too shiny
