Which is bigger

A6 is 4 times the area of A8. 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.

A6 is 53 mm wider than A8. A6 is 74 mm taller.

Printing one on the other

A A8 page fits inside A6 whole — print it at 100% and you get a 26.5 mm border down each side and 37 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

The proportions differ: A6 is 1:1.41 and A8 is 1:1.42. That difference is why a layout moved between them never quite lines up — scale it to fit one edge and the other is left with 0.7 mm of unwanted margin.
