Obviously 1 single sheet of 100# gloss text doesn’t weight 100 lbs. So that poses the question, how is paper weight measured? In the US paper is measured in pounds and designated by the weight of one ream, or 500 standard sized sheets. Not all paper types have the same standard sheet size and not all paper types have the same caliper (or thickness). That’s why smaller sized paper that is thicker can have a weight that is the same of a larger sized but thinner paper. Check out this handy chart to see common paper and the standard (or manufactured) sizes that provide the basis for measurement:
