Which is bigger

A0 is 4 times the area of A2. They are 2 steps apart in the A series and each step halves the sheet, so the multiple is two to the power of 2. The number in the name going up while the sheet goes down is why this has to be asked rather than read off.

A0 is 421 mm wider than A2. A0 is 595 mm taller.

Printing one on the other

A A2 page fits inside A0 whole — print it at 100% and you get a 210.5 mm border down each side and 297.5 mm top and bottom.

These are the numbers for the "custom scale" box in a print dialog. "Fit to page" computes the same thing, but knowing the figure tells you in advance whether the result will look deliberate or accidental.

Why the shapes matter

Both sheets have the same 1:1.41 proportions, so artwork scales between them without any cropping or extra margin — only the size changes.
