Hi i was looking for the same thing as well! and i have found an appropriate and less complicated answer:The International Standards Organisation has prescribed three series, A, B, and C, each with ten different sizes (from zero to ten), as the standard sizes for paper sheets. The size with the largest area is labelled zero and the size decreases in sequence. A4, the most common size, happens to be the fifth in the A series.
Hope that helped you!
A4 paper size is 8.3in × 11.7in.
A4 paper is made of a tree called the paper bark tree, the paper is actually made out of the bark from the tree, that's where its name came from. :)
8 A4 peices of paper and a third
The width and height of ISO A4 paper is 210 × 297 mm.
A4 paper measures 8.27 x 11.69 inches.
A4 is an indicator of size, typically for paper, not of weight. Weight will vary by the material or paper's thickness.

A4 paper is exactly half the size of A3, and they both have the same aspect ratio. So A4 --> A3 is an enlargement. Most photocopiers use A4 as standard. You need a larger photocopier to copy onto A3. The photocopier will usually offer A4 --> A3 as an option.
an a2 has 6 pieces of a4
Yes, B paper is bigger than A paper, for instance the average A4 is 21cm x 29.7cm, however B4 is 25cm x 35.3cm

Half of A4 is A5.
