GSM Calculations

Whether it is printing paper, copy paper, paper stock, newspaper, or any other the plethora of paper products that are produced today, GSM, or grams per square meter , is the standard measurement of paper’s density.

           

The formula I use to calculate the paper’s density is as follows

           

GSM = The area of the paper (calculated in Meters Squared or M²)

            The mass of the paper (calculated in Grams or G)

            I personally come from a scientific background and precision is something I value. So I generally use 3 different measurements.

First, I use the area of one single card divided by the mass of one single card.

            GSM  = Area of 1 card

                        Mass of 1 card

Second, I use 10 times the area of one single card divided by the mass of 10 cards

            GSM = Area of 1 card x 10

                        Mass of 10 cards

Finally I use the 52 times the area of one single card divided by the mass of the deck (52 cards)

            GSM = Area of 1 card x 52

                        Mass of 52 Cards

Finally, the three results are averaged and the results posted on each deck review’s specs section.

If I am incorrect in my methods, feel free to comment and let me know. 

Thanks and enjoy!
