In the old literature on printing, the term "printed sheet" is encountered quite often. Now it is almost out of use. In journalism, books and some other areas, it has long been accepted to count the amount of text in signs. Western and some Russian publishers often use the number of words or the traditional author's sheet as a unit of measurement. However, sometimes it becomes necessary to count the number of printed sheets in any publication.

## Necessary

- - the actual size of the printed sheet;
- - the number of pages in the publication;
- - the size of the conditional printed sheet:
- - ruler;
- - calculator.

## Instructions

### Step 1

A conventional printed sheet is considered to be a sheet of 70x90 cm format. Common newspaper and magazine formats are multiples of a printed sheet. For example, A2 is half of this unit, A3 is a quarter, and A4 is an eighth. These formats are still widely used today. However, book and magazine pages can be of other sizes. In addition, modern printing technologies allow different amounts of text to be placed on the same area, since different sizes and different layout options can be used.

### Step 2

Calculate the actual area of the page in the same way you would for any rectangle. Measure and multiply the length and width. It can be written down with the usual mathematical formula S1 = a * b, where S1 is the area of the strip that exists in reality, and and b are the length and width. Likewise, calculate the area of the printed sheet by multiplying 70 cm by 90. That is 6,300 cm2. For convenience, it can be denoted as S2.

### Step 3

Find the conversion factor for this edition. It is the ratio of the area of an actual book page or newspaper strip to the area of a conventional printed sheet. Find it by the formula k = S1 / S2. It is enough to round up the obtained result to the nearest hundredth.

### Step 4

Count the number of printed sheets throughout the publication. Count the number of book pages or newspaper pages. Multiply the resulting number by the coefficient k. This method of counting is convenient for publications typed in a standard font on a sheet with standard formatting.
