Choosing the right paper weight can be difficult when all you have to go on is a number. GSM paper weight tells you how much a square metre of paper weighs, but it does not necessarily tell you how thick, stiff or premium it will feel in your hands. Understanding what different GSM weights feel like can help you choose paper that suits your project, whether you are producing leaflets, brochures, magazines or product catalogues.
GSM stands for grams per square metre. It measures the weight of paper based on the weight of a square metre of that material. Generally, a higher GSM means heavier paper, while a lower GSM means lighter paper.
However, GSM is not a direct measurement of thickness or quality. Two papers with the same GSM can feel quite different depending on their finish and construction.
For example, an uncoated paper can feel stiffer than a silk paper of the same weight. Silk paper has a smoother surface and a softer feel, whereas uncoated paper can feel more textured and substantial in the hand.
This is why understanding GSM is useful, but feeling the paper for yourself is often the best way to make a decision.
The easiest way to understand paper weight is to compare it with printed materials you already know. The following ranges are useful starting points, although the exact feel will depend on the paper stock and finish.
Think of a thin leaflet delivered through your letterbox. Paper around 80gsm feels light, flexible and relatively easy to handle in large quantities.
This type of weight can be suitable for simple promotional leaflets where the priority is distributing information rather than creating a particularly premium feel.
For example, if you are delivering a large quantity of leaflets to homes, lightweight paper can be a practical choice. Recipients can read the information without needing to handle a heavy or bulky piece of print.
Moving up to around 100gsm to 120gsm gives paper more weight while keeping it relatively flexible. It can be a useful option for leaflets and brochure pages that need a little more substance without becoming unnecessarily heavy.
These weights can work well for informational print, particularly when you want something that feels slightly more substantial than a basic leaflet.
The best choice depends on how the finished item will be distributed and handled, as well as the impression you want it to create.
Paper around 130gsm to 150gsm can provide a more substantial feel while remaining suitable for many multi-page printed materials.
At Gemini Print Solutions, leaflets and four-page brochures commonly fall within the broader range of 80gsm to 150gsm, depending on the requirements of the project.
For a brochure promoting an event, for example, you might choose a lighter weight if it will be handed out in large quantities. If the brochure represents a premium product or service, a heavier option may be more appropriate.
The important point is that the paper should suit the purpose of the printed item, rather than simply being as heavy as possible.
Business cards are a useful reference point when trying to understand heavier paper. Around 200gsm can provide a familiar comparison for people who want to picture a paper weight with more substance than a standard leaflet.
However, business cards are often produced on heavier stocks than this, so 200gsm should be treated as a reference point rather than a universal business card specification.
As paper weight increases, the material will generally feel heavier, but the precise level of stiffness and thickness depends on the stock itself.
Heavier paper is often associated with quality because it feels more substantial when someone picks it up. This can be particularly useful for product catalogues, premium brochures and other materials intended to create a lasting impression.
Imagine a product catalogue showcasing a high-value range. A heavier paper stock may help the publication feel more considered and encourage the reader to spend time exploring its pages.
However, heavier is not always better. The paper needs to work with the format, binding and intended use of the finished product.
Not necessarily. A higher GSM can create a more substantial feel, but the right weight depends on what you want the printed material to achieve.
For some projects, lighter paper is the more practical option. Trade show leaflets, for example, may be carried around all day alongside brochures, samples and other promotional materials. Keeping them lightweight can make them easier for visitors to carry.
For a premium product catalogue, the priorities might be different. A heavier stock can give the publication a more substantial feel and encourage readers to spend longer with the content.
There can also be such a thing as paper that is too thick for the job. If the inner pages of a book are too heavy, they may not turn or move as easily as intended. The finished publication could feel cumbersome rather than comfortable to read.
This is why it is worth discussing the intended use with your printer before making a final decision. They can help you find a balance between the feel you want, the practical requirements and your budget.
GSM is only one part of the experience. The paper’s finish can also influence how it feels and how people perceive its quality.
For example, uncoated and silk papers can feel noticeably different, even when they have the same GSM.
These differences matter because a paper weight that feels right in one finish might not give you the same impression in another.
If you are comparing two options, try to look at both the GSM and the finish rather than assuming the heavier paper will automatically be the better choice.
If you are unsure which GSM will work best, comparing physical samples is one of the most useful things you can do.
When looking at samples, consider how the paper feels in your hand, how stiff or flexible it is, and whether its weight suits the purpose of your project. For multi-page publications, it is also worth considering how the pages turn and how the finished item will feel to hold.
You should also check how much printing on one side shows through to the other. Very lightweight paper can allow the reverse-side printing to show through, which may affect readability and the overall appearance of the finished piece.
Most importantly, compare samples that reflect the options you are actually considering. Looking at different GSM weights alongside different finishes can help you understand the differences much more clearly than comparing specifications alone.
At Gemini Print Solutions, you can request paper samples or booklet samples to compare your options. If you are also considering different weights or finishes, you can ask for a quote for each option. Quotes are free, and your samples can be prepared while your quote is being put together, allowing everything to be delivered together.
You can get in touch by email, contact the team or speak to your account manager to discuss the options for your project.
GSM is a useful starting point when choosing paper, but it should not be the only factor in your decision. A lightweight leaflet can be the right choice for large-scale distribution, while a heavier stock may suit a premium product catalogue. The finish, format and way the finished item will be used all influence the result.
If you are unsure, ask your printer for advice and request samples before committing to a specification. Comparing the options in person can help you find the right balance between feel, practicality and cost.
