That's far too broad a question to answer here. There are over 200 countries in the world and most of them use a different size for each denomination, so a thorough answer would take over a thousand lines.

A piece of paper has three dimensions. They are the length, width and thickness of the paper. Paper is available in many sizes such as A1, A3, A4 and A5.
The size of A5 is 210mm on 148mm. In general, the size of A4 is twice bigger than A5, A3 is twice bigger than A4, and so on...
A5 size paper is: 14.8 cm by 21.0 cm
yes A6 is half of A5 :)
A5.
not much
A single sheet of A5 paper measures 21.0 centimetres long by 14.8 centimetres wide.
you use A5 paper
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
148 X 210mm - I assume you mean the dimensions!
An A5 sheet of paper measures 21 cm x 14.8 cm.It is exactly half the size of an A4 sheet of paper.
Just fold it in half. A4 is 210 x 297 mm; A5 is 148 x 210 mm.
