Which is bigger
C4 is 8 times the area of C7. They are 3 steps apart in the C series and each step halves the sheet, so the multiple is two to the power of 3. 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 148 mm wider than C7. C4 is 210 mm taller.
Printing one on the other
A C7 page fits inside C4 whole — print it at 100% and you get a 74 mm border down each side and 105 mm top and bottom.
| You want | Set the print scale to | Leaves |
|---|---|---|
| C4 artwork on C7 paper | 35.2% | 0.4 × 0 mm margin |
| C7 artwork on C4 paper | 282.7% | 0 × 1.7 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 1:1.41 proportions, so artwork scales between them without any cropping or extra margin — only the size changes.
