Successive paper sizes in the series (A1, A2, A3, etc.) are defined by halving the area of the preceding paper size and rounding down, so that the long side of A(n + 1) is the same length as the short side of An. Hence, each next size is nearly exactly half the area of the prior size. So, an A1 page can fit two A2 pages inside the same area.
The size and proportions of a book depend on the size of the original full sheet. If a sheet 480 by 640 mm (19 by 25 in) is used to print a quarto, the resulting untrimmed pages, will be approximately half as large in each dimension: width 240 mm (9 + 1 ⁄ 2 in) and height 320 mm (12 + 1 ⁄ 2 in).
Then the user chooses a spine size that will match the document. Standard sizes are 4.8 mm ( 3 ⁄ 16 in) (for 16 sheets of 20# paper) up to 51 mm (2 in) (for 425 sheets). Spine lengths are generally 280 mm (11 in) to match the length of letter-size paper.

Although metric, based on the A4 paper size, and named to suggest that it is part of the official ISO 216 paper sizes, it is only a de facto standard. It is often referred to as (metric) "foolscap" or "folio" because of its similarity to the traditional foolscap folio size of 8 + 1 ⁄ 2 in × 13 + 1 ⁄ 2 in (216 mm × 343 mm).
