Whether you’re creating brochures, business cards, posters, or large-format prints, the GSM of your paper can significantly enhance both the aesthetic appeal and longevity of your materials.

This guide explores everything you need to know about GSM, breaking down the different paper weights and providing expert recommendations on how to choose the ideal paper for your specific printing needs. With our vast experience working with various paper types and print finishes, we ensure that every print job not only meets but exceeds expectations.

What Is GSM in Paper and Why Does it Matter?

GSM (grams per square metre) measures the weight and thickness of paper, it can also be known as the Grammage of the paper. Different gsm's are used for a variety of reasons such as effect, cost and quality in some instances.  Whilst a higher gsm dosen't necessarily affect quality when it comes to printing, it can help. Newspapers are always a low gsm to prioritise cost margins and disposability and are generally considered low quality. Whereas booklet's are printed with a higher gsm cover and lower gsm inner pages, the varying gsm's providing a higher quality feel to the product.

But whilst GSM can be an indicator of quality, it is not always reflective of it, users require different features and gsm's out of paper for different purposes. Fountain pens paper is the perfect example of this as often times a higher gsm is not ideal. This is because, according to Jetpens:

"A higher paper weight doesn’t necessarily mean that the paper is better or less likely to exhibit feathering or bleedthrough. Paper weight matters most when it comes to combining sheets into a notebook or notepad. Thinner paper allows for notebooks to have more pages, though it also generally increases the likelihood of showthrough." [JetPens].

Lower gsm's are often the standard here and the quality of the paper is prioritised over the thickness, but even then, some writers may prefer a slightly thicker paper, on top of quality, to reduce show through and for the general feel of writing; emphasising how gsm is preference and not linked to quality. 

Examples of different GSM's for Printing
Here are some examples of use cases for different paper gsm's:

•    Lower GSM papers (70-100 GSM) are thin, lightweight, and ideal for high-volume printing (e.g., newspapers, office paper, hand outs). They emphases disposability and cost margins, so they are as thin as they can functionally be without affecting legibility.

•    Mid-range GSM papers (120-170 GSM) are great for flyers, posters, and brochures, offering a balance of flexibility and quality. Designed to be read through or kept around for future reference, they need the added durability that a higher gsm provides, whilst still being foldable and malleable enough to fit inside a pocket or bag.

•    High GSM papers (200-400 GSM) provide sturdiness and a premium feel, making them ideal for business cards, wedding invitations, and luxury print products. Designed to be kept and often complimented by foiling and other premium printing features.

•    Very High GSM duplex papers (400+ GSM) maximum sturdiness and very unique and premium feel, ideal for bespoke printing options. Very niche case printing for specific needs and requirements.
