Paper weight equivalence table
Use the following table to determine approximate equivalent points in weight specifications other
than U.S. bond weight. For example, to determine the equivalent of 20 lb U.S. bond weight paper
in U.S. cover weight, locate the bond weight (in row 3, second column) and scan across the row
to the cover weight (in the fourth column). The equivalent is 28 lb.
Shaded areas indicate a standard weight for that grade.

1. U.S. postcard measurements are approximate. Use for reference only.
2. Text and book grades actually calculate out to 51, 61, 71, and 81, but are standardized to book/text weights of 50, 60, 70, and 80.
