Weight Comparison Chart

Bond Ledger Book Kraft Tag, News MM Factor Approx. Caliper This chart is particularly useful for comparing the actual weights of sheets to determine the best sheet for a job or for a possible substitution. For example 90 lb. index is exactly the same weight as 100 lb. tag but about 10% heavier than 100 lb. book. MM Factor is the weight of 1000 sheets 1000 square inches in size (1000 sh. 25" x 40"). To find the weight of 1000 pieces of any size sheet simply multiply its MM Factor by the square inches and move the decimal three places to the left. 17 x 22 25 x 38 24 x 36     Wt. 500 Sh.
