Paper Weight Equivalence Table Use this 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. Table 1-13. Paper Weight Equivalence 1 2 3 4 5 6 7 8 9 10 11 12 14 13 15 16 1.
