How to Ascertain the Quantity of Plain Type Required for Newspaper.
To ascertain the quantity of plain type required for a newspaper, magazine, and other work, find the number of square inches and divide the same by four; the quotient will be the approximate weight of the matter. As it is impossible to set the cases entirely clear, it is necessary to add 25 per cent to large fonts, and 33 per cent to small, to allow for dead letter. This, of course, is only approximate, but will be found sufficiently close for all practical purposes.
