Paper GSM Explained: A Simple Guide for Choosing Notebooks and Notepads
Share
If you've spent any time browsing custom branded notebooks or notepads, you've probably seen "GSM" listed somewhere in the product details and wondered what it actually means for what you're about to order. It's one of those specs that gets thrown around a lot in the print and stationery world without much explanation — so here's the simple version.
What Does GSM Actually Mean?
GSM stands for grams per square metre. It's simply a measure of how much a single square metre of a given paper would weigh. The higher the GSM number, the thicker, heavier and more substantial the paper feels in your hand.
That's genuinely all it is — a weight measurement, not a complicated quality rating. But because weight and thickness are closely linked, GSM ends up being a useful shorthand for how premium, durable or "flimsy" a piece of paper will feel.
Why GSM Matters When Choosing Notebooks and Notepads
Paper weight affects a few practical things that matter for promotional merchandise:
- How the paper feels — higher GSM paper feels more substantial and premium in hand, which affects how recipients perceive the overall quality of the item
- Ink bleed-through — lighter GSM paper is more prone to pen or marker ink showing through to the next page, particularly with felt-tip pens or heavier writing pressure
- Durability — heavier paper resists tearing, creasing and general wear better than lighter stock, which matters for items that get carried around and used repeatedly
- Cost — heavier paper generally costs more to produce, which is reflected in the price difference between budget and premium notebook or notepad ranges
None of this means heavier is always "better" — it depends on what the item is for. A lightweight notepad used for quick reminders doesn't need the same paper stock as a premium notebook meant to feel like a genuine corporate gift.
Common GSM Ranges, Simplified
Paper GSM can range from tissue-thin to cardboard-stiff, but for notebooks and notepads, most stock falls into a few practical bands:
Around 60–80gsm — Standard writing paper This is a similar weight to standard office printer paper. It's perfectly functional for everyday note-taking, but pen ink can occasionally show through on the reverse side, particularly with felt-tip pens.
Around 80–100gsm — Mid-weight paper A step up from standard paper, this range feels noticeably more substantial without a big jump in cost. It's a common choice for good-quality promotional notebooks and notepads, offering a solid writing surface with minimal bleed-through.
Around 100–120gsm — Premium notebook paper This is where paper starts to feel genuinely premium — thicker, smoother, and much more resistant to ink bleed-through. It's commonly used in higher-end branded notebooks meant to feel like a considered corporate gift rather than a basic giveaway.
250gsm and above — Cover and cardstock weight This range is generally used for covers rather than internal pages — think the front and back cover of a notebook or notepad, which need to be stiff enough to protect the pages and hold their shape with regular use.
How This Applies to Our Notebooks and Notepads
Different products in our range are built for different purposes, which is reflected in the paper stock used. Our notebooks collection spans everything from everyday spiral-bound and softcover options through to premium PU leather and hardcover styles, with paper weight generally increasing as you move toward the more premium end of the range. Our notepads collection is built around practical, functional use — ideal for conferences, meetings and everyday office use, where a solid mid-weight paper strikes the right balance between quality and cost-efficiency across larger order volumes.
If you're not sure which paper weight suits your intended use, that's exactly the kind of thing our team can help you land on — it usually comes down to how the item will be used, how premium you want it to feel, and your budget per unit.
A Simple Way to Think About It
If you remember nothing else from this guide, remember this: GSM is just weight, not quality on its own — but weight is a genuinely useful proxy for how premium, durable and resistant to ink bleed-through a paper stock will be. Lighter paper suits high-volume, budget-friendly giveaways. Heavier paper suits items meant to feel like a genuine, lasting gift.
Frequently Asked Questions About Paper GSM
What does GSM stand for? GSM stands for grams per square metre — a standard unit used to measure the weight, and therefore the thickness, of paper and card.
What GSM is best for a notebook? For everyday notebooks, 80–100gsm offers a good balance of quality and cost. For a more premium feel with minimal ink bleed-through, 100–120gsm is a common choice for higher-end branded notebooks.
Does higher GSM always mean better quality? Not necessarily. Higher GSM generally means thicker, more durable paper, but the "right" GSM depends on the intended use. A lightweight notepad for quick notes doesn't need the same paper weight as a premium corporate gift notebook.
Why does my pen bleed through the pages of some notebooks? This usually happens with lighter GSM paper (around 60–80gsm), particularly when using felt-tip pens or writing with heavy pressure. Choosing a notebook with 90gsm paper or higher generally reduces or eliminates bleed-through.
What's the difference in paper weight between a notebook cover and its pages? Notebook and notepad covers are almost always a much heavier stock than the internal pages — often 250gsm or higher — since the cover needs to be stiff enough to protect the pages and hold its shape with regular use.
