Magnification Factors of Photocopying & Paper Scale

This article is about a paper size scale and magnification factors. The ISO 216 paper sizes have a few excellent characteristics when it meets expectations, increasing in size and lowering documents because they all have the same facet percentage if the A4 page size is increased to A3, the borders about the page forbiddance change specifically that the top and side borders are of considerably various capacities, and you don’t take the text missing situated above, bottom, or edges. 

scale

The scale determinant for each decline or expansion is alike, so lowering from A3 -> A4 (71%) is the unchanging measuring as from A4 -> A5 and from A5 -> A6. The scale determinant for the decline is determined by separating the lengthier edge of the tinier breadth from the more long edge of the best size (or the smaller edge of the tinier proportion individually smaller edge of the best size).

A Paper Size Scale & Magnification Factors

Here, we are providing two types of size selector boxes wherein a user can select a standard A series size according to his need. As soon as the size is one selects from the user end, the corresponding magnification factor appears simultaneously in the factor boxes provided by us. The representation of the magnification factor will be in terms of percentage and decimal.

When it comes to the enlargement and reduction of documents, then ISO 216 paper sizes show some very great properties. It is because they provide the same aspect ratio even if you enlarge an A4 page to A3 size. There is no loss of data as the margins around the page do not very much at the top and at the sides.

Magnification Scale Factors Background

If we apply our mathematical concepts, then the scaling factor between the A4 and the A3 sheet sizes is the square root of two. Also, you can express it in terms of percentage and if we consider the scaling factor, then it is square of root two, that is, 2. The square root of two (2) expressed as a part is a determining factor for measuring positions A4 and A3. The measuring factor ‘tween A4 and A2 is (√2)2 (namely 2), meant as a portion. The table beneath gives common formulae for conversions ‘tween various sizes of the unchanging order and conversions middle from two points order for A and B paper sizes.
