Paper CaliperThe tables below show the approximate caliper (or thickness) for a single sheet of paper of various grades and basis weights.

These tables are organized by grade, with the left column listing selected standard basis weights for that grade and the right column listing the average caliper for a given grade/basis weight of paper.

Note that caliper here is expressed in thousandths of an inch or, in some cases, as much as hundred thousands of an inch. In the paper industry, paper thickness is also expressed in points (a single point is equal to .001″). To convert these decimal-inch values into points, divide the avg. caliper number by .001. For example, a sheet of paper that is .0095″ thick has a caliper of 9.5 points.


The numerical data in these tables are averages only and are not guaranteed.
