For example, JB3 is 364 × 515, JB4 is 257 × 364, and JB5 is 182 × 257 mm. It introduces additional magnification factors and is not an international standard.The following table shows the width and height of all ISO A and B paper formats, as well as the ISO C envelope formats.Similarly, the formats of the C series are the geometric mean between the A and B series formats with the same number.

The same principle works for books in B5 or A5 format.
Copying machines designed for ISO paper sizes usually provide special keys for the following frequently needed magnification factors: Not only the operation of copying machines in offices and libraries, but also repro photography, microfilming, and printing are simplified by the 1:sqrt(2) aspect ratio of ISO paper sizes.
If you prepare a letter, you will have to know the weight of the content in order to determine the postal fee.
This can be very conveniently calculated with the ISO A series paper sizes.
Using standard paper sizes saves money and makes life simpler in many applications.
For example, if all scientific journals used only ISO formats, then libraries would have to buy only very few different sizes for the binders.The ISO standard paper size system covers a wide range of formats, but not all of them are widely used in practice.Among all formats, A4 is clearly the most important one for daily office use.The dimensions are in millimeters: The allowed tolerances are ±1.5 mm for dimensions up to 150 mm, ±2 mm for dimensions above 150 mm up to 600 mm, and ±3 mm for dimensions above 600 mm.Some national equivalents of ISO 216 specify tighter tolerances, for instance DIN 476 requires ±1 mm, ±1.5 mm, and ±2 mm respectively for the same ranges of dimensions.ISO 216 defines the A series of paper sizes based on these simple principles: For applications where the ISO A series does not provide an adequate format, the B series has been introduced to cover a wider range of paper sizes.The C series of formats has been defined for envelopes.Therefore, the area of the pages has been defined to have round metric values.As paper is usually specified in g/m², this simplifies calculation of the mass of a document if the format and number of pages are known.Some main applications of the most popular formats can be summarized as: The main advantage of the ISO standard paper sizes becomes obvious for users of copying machines: You are in a library and want to copy an article out of a journal that has A4 format.In order to save paper, you want copy two journal pages onto each sheet of A4 paper.
