Buying print online can often feel like playing a guessing game. You are faced with a dizzying dropdown menu of technical numbers, abstract acronyms, and vague descriptions, all while trying to figure out if your new company brochure will feel like a sleek publication or a flimsy takeaway leaflet.

At the heart of almost every paper selection is a single acronym: GSM.

GSM stands for grams per square metre. Technically speaking, it is a measurement of the weight of a single sheet of paper cut to one square metre in size. In practical terms, however, GSM is simply print shorthand for how thick, heavy, and sturdy a sheet of paper feels in your hands.

The problem is that numbers on a digital screen do not translate naturally to physical touchpoints. Knowing that a flyer is printed on 150gsm paper does not instantly tell you whether it will flop over when held or sit crisp and upright on a display stand.

At Print Lord, we believe buying print should be simple, clear, and completely stress-free. You should never have to guess whether your marketing materials will do your brand justice. To help you choose the perfect paper weight for your next project, here is our plain English guide to understanding GSM, translating numbers into real-world touchpoints.

80gsm to 100gsm: Everyday Office & Letterhead Stocks

This is the lightweight territory. If you pull a standard sheet of blank paper out of a home or office desktop printer, you are almost certainly holding an 80gsm sheet.

How it feels

Thin, light, flexible, and easy to fold. It has a familiar everyday feel that works perfectly for reading black and white text, but it offers very little rigidity.

Best used for

• Official company letterheads
• Compliment slips
• Multi-page transactional documents and invoices
• Internal office memos and forms
• Inside pages for thick, bound notepad products

Why weight matters here

While 80gsm is fine for internal paperwork, stepping up to 90gsm or 100gsm for your corporate letterheads and compliment slips makes a subtle but noticeable difference. A 100gsm letterhead feels crisp, smooth, and professional in a client’s hand without being so thick that it chokes standard office laser printers or postal envelopes. Anything lighter than 80gsm risks ink show-through, where text printed on one side bleeds visually through to the back.

130gsm to 170gsm: The Workhorse Flyer & Leaflet Stocks

When you step into the 130gsm to 170gsm range, you leave plain paper behind and move into the world of light commercial papers. This is the absolute sweet spot for high-volume promotional print.

How it feels

Substantial, smooth, and flexible without feeling cheap. A 130gsm sheet feels like a page from a high-quality glossy magazine, while 170gsm feels like a sturdy takeaway menu or event guide that holds its shape nicely when held with one hand.

Best used for

• High-volume promotional flyers and leaflets
• Folded takeaway menus and price lists
• Magazine and brochure inner pages
• Event programmes and newsletter inserts
• Direct mail door drops

Why weight matters here

If you are running a massive door-to-door leafleting campaign where keeping unit costs and delivery weight low is vital, 130gsm paper delivers excellent print performance at a budget-friendly price. However, if your flyer is being handed directly to a prospective customer at an exhibition or sales meeting, upgrading to 170gsm instantly elevates your brand perception. It gives the artwork tactile weight, prevents premature creasing, and feels deliberate rather than disposable.

250gsm to 300gsm: Brochure Covers & Sturdy Promos

Crossing the 200gsm threshold brings you into heavy paper and lightweight board territory. This is where print starts to feel structured, rigid, and premium.

How it feels

Firm, durable, and thick. When you hold a sheet of 250gsm or 300gsm board, it does not flop or bend under its own weight. It feels like a high-end greetings card or a substantial booklet cover.

Best used for

• Covers for multi-page booklets, catalogues, and brochures
• Premium event invitations and VIP passes
• High-end presentation folder inserts
• Standalone counter display cards and desktop guides
• Corporate announcements and event menus

Why weight matters here

If you are printing a multi-page corporate brochure, pairing a sturdy 250gsm or 300gsm cover with 150gsm inner pages creates a magnificent contrast. The heavy cover acts as a protective shield for the content inside while signalling to the reader that what they are holding is valuable and worth keeping.

350gsm to 400gsm: Heavyweight Luxury Boards & Business Cards

Welcome to the heavy artillery of the paper world. Stocks in the 350gsm to 400gsm range are solid, premium cardboards engineered for maximum durability and tactile impact.

How it feels

Thick, unyielding, and reassuringly heavy. It requires real effort to bend, offering a solid, high-status presence between your fingers.

Best used for

• Professional business cards
• Luxury postcard mailers and promotional cards
• Gift vouchers and loyalty cards
• Appointment cards and corporate pass tags
• High-impact direct mail items

Why weight matters here

Your business card is often the very first physical touchpoint a prospective client experiences from your company. Handing someone a limp, flimsy 250gsm business card communicates uncertainty before you have even said a word. A 350gsm or 400gsm card, especially when finished with a velvety soft-touch or crisp matt lamination, conveys confidence, craftsmanship, and authority instantly.

Quick Reference: Matching Your Project to the Right GSM

To keep things as simple as possible when planning your next project, use this quick touchpoint guide:

• 80gsm – 100gsm: Everyday office paper, multi-page invoices, crisp corporate letterheads.
• 130gsm – 170gsm: High-volume promotional flyers, folded brochures, takeaway menus, booklet inner pages.
• 250gsm – 300gsm: Sturdy brochure covers, premium event invitations, counter display cards.
• 350gsm – 400gsm: Heavyweight business cards, direct mail postcards, luxury vouchers, loyalty cards.

Does Finish Affect How Heavy Paper Feels?

It is worth noting that GSM measures weight, not physical thickness. Two different paper stocks with the exact same GSM rating can feel subtly different depending on their finish and density.

For instance, an uncoated paper stock naturally absorbs more air during manufacturing, making it feel slightly bulkier and rougher than a coated silk or gloss paper of the same GSM weight. Additionally, adding protective finishes like lamination (matt, gloss, or soft-touch) to a 350gsm card adds physical thickness, rigidity, and water resistance, raising the overall luxury feel of the item.
