Casting Up

Calculating the number of thousands of letters in a sheet of any work, or in a job, in order to fix the price for composing it.

To facilitate the ascertainment of the number of thousands of letters in a sheet of bookwork, and also of jobs, I have given a set of tables, which I believe includes, generally speaking, the sizes of the pages that usually occur in practice. These tables will be found useful to those compositors who are not expert at figures, while those who are so may save time by referring to them, and they may also serve as a check to their own casting-up.

The figures at the top designate the number of lines the page is long; and the figures in the column specify the number of thousands of letters in a sheet, according to the size named in the head. To ascertain the number of thousands of letters, the established rule is, to take the number of lines the page is long, including the head line and the direction line, and the number of en quadrats in the width of the page the en quadrat being estimated as the average thickness of the letters, and on multiplying the one by the other the product will give the number of letters in a page.

And this product multiplied by the number of pages in a sheet, gives the number of letters in a sheet; where there is a fraction of a thousand, and that fraction amounts to 500 or upwards, it is reckoned and charged as 1,000; when it is less than 500 it is dropped, and not included in the calculation. There are some exceptions to this general rule of taking the dimensions when the type exceeds a certain size, for which see Scale of Prices.
