Which is bigger

A8 is 4 times the area of A10. 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.

A8 is 26 mm wider than A10. A8 is 37 mm taller.

Printing one on the other

A A10 page fits inside A8 whole — print it at 100% and you get a 13 mm border down each side and 18.5 mm top and bottom.

A8 artwork on A10 paper	50%	0 × 0 mm margin
A10 artwork on A8 paper	200%	0 × 0 mm margin

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 1:1.42 proportions, so artwork scales between them without any cropping or extra margin — only the size changes.
