Gsm and Micron have no direct correlation. You can’t just convert 1 into another. GSM is weight and micron is thickness. We have measured some of our most popular card stocks.
115gsm = 90 micron
150gsm = 140 micron
160gsm recycled = 180 micron
235gsm (greetings card) = 355 micron
300gsm = 290 micron
300gsm recycled = 340 micron
400gsm = 420 micron
2 men both weigh 85kg each. One man is tall and THIN. The other short and FAT.
2 pieces of paper both weight 180gsm. One is thin. The other is thick.
The most asked question. What is ***gsm in micron? or How many Micron is ***gsm.
What you are actually asking is how thick is 3kg? or How much does 10cm weigh.
Paper Weight – What is GSM
Paper weight and thickness, let’s start with GSM – paper weight. GSM stands for Grams Per Square Meter, a measurement used to identify the weight of different types of paper and card. The higher the value of GSM, the heavier card or piece of paper. So a 1msq 400gsm board weighs 400 grams.
So, the difference between our 300gsm Cheap Business Cards and our 400gsm Premium Business Cards is simply, the weight of the card. Similarly, a 120gsm letterhead is bulkier than a 90gsm letterhead. A heavier card or piece of paper contributes to a more premium feel and lasting effect with your customers.

Definition of Micron – The Thickness of Paper.
Card thickness or calliper is traditionally measured in Microns.
1000 Microns = 1mm, so the higher the value, the thicker the card or paper.
Usually paper or card is sold by weight as opposed to thickness, but sometimes you may see Microns instead. Thickness of card sold usually starts at around 200 microns, and finishes at around 500 microns.
Micron and GSM – are they linked?
Yes and no. It depends on the type of material used.
Many people confuse paper weight with paper thickness! You could have a situation whereby two 150gsm papers weight the same, But one could be a thick vellum paper containing air and bulk and the other could be calendared a process that involves compressing the paper with high pressure rollers. Both are classified as 150gsm paper stock, but look and feel very different.
1000 micron waterproof PVC material used for banners, has a different weight to 1000 micron silk paper, and therefore has a different Gramme Per Square Meter. When checking between prices for different print products, it is therefore important you look at the type of material, GSM and micron to get an exact comparison.
Sometimes you may also see the term ‘sheets’ advertised, where thickness of card refers to how many typical sheets thick it is. At BrunelOne.com, we tend to stick to just GSM and Micron, though.
whoah this blog is magnificent i like studying your articles.
Keep up the great work! You understand, many people are searching round for this info, you can aid them greatly.
I am trying to make my own paper but how can I know what 150gsm is? Is there a way of measuring that I can use?
Hi Liz you would have to measure the area of the paper. For example 1 meter square of paper – then weigh the paper. A 1 square meter piece of paper weighing 300 grams would be 300gsm.
If you had half a square meter that weighed 300 grams the gsm would equal 600gsm – grams per square meter.
Thanks for wonderful information!
I found this a bit boring as it is quite long
Have a question, years ago I used to use a Handheld Scale to find paper weight and the GSM by hanging the media from a clip. It was like a Manual Torque scale that are used for Lug Nuts on a car (the scale type), this is a very small unit that can be carried in a Technician’s tool bag (copier repair). I have been looking for this tool or a updated mobile tool that can be used easily but have not seen them. I can’t remember the name for the tool. Do you know what I am describing or where I can find them to purchase? Any information you can provide me with is greatly appreciated.
Thank you for sharing such great information. It’s a pleasure to visit here. You can also visit us in INDEV ACT .
I have 350gsm with 470um board, the sheets height is 8950mm, how many sheets will be on this pallet please.
thanks very much and Regards
Is it possible to calculate the bulk of the sheet from the details given in label of paper packet
please convert 1000 Micron into GSM
I dugg some of you post as I cogitated they were very useful very
This is wonderful information. I make a lot of cards and journals so it’s important how heavy or thick the card is. A 400gsm card would be useless as a card blank because it’s too thick to fold and score nicely but the same weight cardstock would be ok for a journal if you found a nice weight DSP to wrap it will be ok. Thank you for making it so easy to understand. Kind Regards Wendy.
