The 80 gram per square meter means how much 1 square meter of this particular paper weighs. 16 sheets of A4 paper are actually 1 square meter.I've always designed my models with the intent of using 110 lb. card stock. I get confused with all these paper specs, I have no idea what "80 gram per square meter or higher means".
This fact can be used to assess the paper thickness of a given pack of paper.
Most of the Polish models use 160 g/sq meter paper and usually this paper is 0.22 mm thick
Your regular office paper is usually 80 grams per square meter, sometimes 70 and sometimes 90.
Need to notice that the different paper of certain weight per square meter not always will be the same thickness. For example, depending on paper's density, 160 grams per square meter paper's thickness can vary from 0.2 to 0.24. Although 0.01 mm is almost not noticeable, sometimes this difference can cause a lot of headache in parts fitting
I from the other hand, don't really understand what 110 lbs card stock measurement means.
