Which is bigger

C4 is 4 times the area of C6. They are 2 steps apart in the C 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.

C4 is 115 mm wider than C6. C4 is 162 mm taller.

Printing one on the other

A C6 page fits inside C4 whole — print it at 100% and you get a 57.5 mm border down each side and 81 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: C4 is 1:1.41 and C6 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.
