An average office employee uses at least 10,000 sheets of paper per year. That comes down to at least 28 sheets of paper per day.
And we haven’t even included the average use of paper by schools and other such institutions.
But have you ever wondered what in fact is the point of creation of these staggering amounts of paper? Or what are the specifications one needs to know while purchasing paper?
Well, to scratch the surface, paper is circulated globally by the essence of its weight, and is called GSM paper. Well not essence in particular, but you get the gist of it.
On the other hand, if you are still a tad bit confused about it, or need to know more about how the entire concept of GSM paper works then get your reading glasses on because we are about to discuss some heavyweight paper, pun intended.
Let’s begin at the beginning.
What in fact is a GSM paper?
It would not be wrong to say that GSM could be a quantified term. GSM is an acronym for ‘grams per square meter’. To simplify it for you, the standardization of various types of paper in terms of weight is done through a sample sheet that is one square meter in size.

After this sample sheet has been procured, it is used as an ideal for all sorts of other purposes. It is important to note that this sample remains consistent, doesn’t matter the length or breadth of the paper. Let us explain this to you with the help of an example.
Let’s say a sheet of paper weighs 200 gsm. This means that every square meter of that entire sheet – be it A4 or A5 – weighs 200 gsm irrespective of its size.’
Moreover, different weights in GSM represent different textures of paper. For example, a paper with a weight of 40 gsm would be much thinner and lighter than a paper that weighs 350 gsm. The 350 gsm paper, on the other hand, would be thicker and durable and has its own designated purposes.
A Note to Remember:
A paper that weighs 40 gsm will not weigh the same when cut down to poster size or letter size. Either way, both the types will be considered 40 gsm paper as ‘gsm’ represents a quantified thickness or thinness.

If you still find it difficult to conceptualize this paper world, then we have it planned one step ahead of you. Here is a YouTube video explaining all that you need to know about GSM paper in less than a minute.
In this video, you will be briefed upon what GSM paper is and why it is important. Moreover, you will learn about various GSM paper related weight measurements, and which sort of paper is compatible for various works such as sketching, printing, promotion and more.
Should you really care about the weight of the paper that much?
Well to sum up, yes. The weight of the paper that one uses is crucial to the sort of work being done. It is important enough to have a term after it. GSM of a paper decides what it should be used for, and is referred to as the paper’s ‘grammage’.
That is not the only reason you should take the weight of your paper seriously. There are various other reasons, and to name a few:
- Different types, different styles

- Avoid ink related faux-pas
If you are using a paper that weighs 90 gsm or below, then there is a high probability of the ink bleeding through the paper, rupturing your designs or work. To avoid putting yourself in a faux-pas, it is recommended that you use the GSM paper based on the type of work you have to do.
- Suit Up Your Business!

Naturally, you would like a stiff and sturdy business card rather than a flappy and easily bendable one. So, suiting up your paper is also important.
Now, GSM paper is used for almost all the purposes one could use paper for. To further help you understand it, here is a summary of the standard weight of the paper and what it is used for:
- 35 gsm – 55 gsm: The thinnest kind of paper available, this type of GSM paper is translucent and primarily used for tracing or for newsprints.
- 75 gsm – 90 gsm: This type of GSM paper is ideally used for sketch pads or notepads, as it is suitable for some light paperwork or sketching. If one were to use ink on it, there is a hundred percent chance it will bleed through.

- 120 gsm – 140 gsm: Think promotional paper! This type of GSM paper is commonly used as movie posters or is also used for displaying various products at stores for promotional purposes.
- 210 gsm – 300 gsm: This type of GSM paper is comparatively stiffer yet bendable. One might come across this paper on some magazines and high quality flyers. In fact, most bases for watercolor or painting papers are made from this GSM paper.
- 350 gsm – 450 gsm: This type of GSM paper is the stiffest and sturdiest out of all the papers, and is like cardstock. One may have encountered these types of papers on business cards or invitations.
Measurements – How do GSM paper measurements work?
Naturally, there are different measurements used for different textures and styles of papers. It primarily depends on the sort of work one needs to do, and there are standard sizes for everything. For example, the standard size of a business card will differ from the standard size of a letter, or a brochure for that matter.

ISO A Paper – Measurements and Sizes
The internationally accepted standard for GSM paper is ISO A. It uses millimeters and meters for measurement purposes. The largest format in this type of GSM paper is A0, which is one square meter in size.
The next step of measurement is taken by cutting down the initial size of GSM paper into half along the widest dimension. For example, the next size that comes after A0 is A1. Thus, A1 is dictated by cutting A0 in half.
Here is a list of the most accepted sizes from a range of A0 which is the largest size, to A10 which is the smallest size.
- A2 – 420 x 594 mm (or 16.54 x 23.39 inches)
This size of GSM paper is used in maps, smaller posters or even diagrams.
- A4 – 210 x 297 mm (or 8.27 x 11.69 inches)
This size of GSM paper is used in magazines, catalogs, letters and documents.
- A6 – 105 x 148 mm, or 4.13 x 5.83 in
This size of GSM paper is used in postcards. It is also a common print size for photographic pictures.
ISO B Paper – Measurements and Sizes
Another common type of sizing schedule used for measuring GSM paper is ISO B. This standard of measurement is primarily used for poster sizing.
Similar to A0 size of paper, the B0 size is also the largest succeedingly going down to B10 which is the smallest measurement of GSM paper of this standard.
Here is a list of the commonly and globally accepted sizes from ISO B:
- B4 – 250 x 353 mm (or 9.84 x 13.90 inches)
- B2 – 500 x 707 mm (or 19.69 x 27.83 inches)
- B0 – 1000 x 1414 mm (or 39.37 x 55.67 inches)
ISO C Paper – Measurements and Sizes
ISO C is another globally accepted standard of GSM paper measurement. However, here the only difference is that it is applicable to the sizes of envelopes that fit and correspond to the varied sizes of ISO A Paper.
Here is a list of the commonly and globally accepted sizes from ISO C:
- C6 – 162 x 114 mm (or 6.38 x 4.49 inches)
- C4 – 324 x 229 mm (or 12.76 x 9.02 inches)
- C2 – 648 x 458 mm (or 25.51 x 18.03 inches)
