3 What Cover Weight is it? Look at the above Chart in the first column, find 300 gsm. Scroll over to the Cover Weight column and you will see that it would be called 111# #4, I have an 80# Text Weight paper. How many gsm is it? Go to the Text Weight column and find where 80# would be listed. Scroll to the left to the first column and estimate where it would fall in the GSM column. In this case it would be about 118 gsm.
