Opacity, based on a 100-point scale, measures the translucency of the paper. For example, if a sheet of paper has 80% opacity, 80% of light cannot pass through. Paper with a higher opacity is preferred for double-sided printing.

Paper weight, stated in pounds (lbs.), is calculated by weighing a ream (500 sheets) of the basis size (master uncut size) of that paper type. For example, the basis size of bond paper is 17″ x 22″ with a ream weighing 20lbs; the basis size of watercolor paper is 22″ x 30″ with a ream weighing 140 lbs.
