Paper Thicknesses

Paper Confusion

Paper thickness designations can be tricky

Stock designations in printing can be very confusing. For instance, a printer may use 60# offset stock for letterhead, giving the customer the impression that a competitor’s 24# stock is inferior. In fact, 24# bond, and 60# offset weights are approximately the same, only the offset stocks are finished for offset printing, while bond stocks are more often used for spot color stationery printing.

The table below might help you sort out how one type of paper measure compares to others. we hope this will take some of the mystery out of a complicated process.
