How the A series works
Each size is exactly half the one before it, cut across the longer side. A4 is half of A3, A3 is half of A2, and so on up to A0, which is one square metre. That is why the proportions never change: every sheet in the series has the same 1:√2 ratio, so artwork scales between them without cropping.
The B series sits between the A sizes — B5 is larger than A5 and smaller than A4 — which is why textbooks and journals often use it. Foolscap and Legal are not part of either series, which is why documents set for them do not scale cleanly onto A4.
Which of these can you actually order
A5, B5, A4 and A3. A5 costs Rs 0.38 per page printed double-sided in black and white, falling to Rs 0.34 at 100 copies or more, which is the cheapest rate we publish. A4 is Rs 0.60, and Rs 0.54 at 100 copies or more. A3 and B5 are priced in the official calculator.
