C6 vs C3
| C6 | C3 | |
|---|---|---|
| Millimetres | 114 × 162 | 324 × 458 |
| Inches | 4.49 × 6.38 | 12.76 × 18.03 |
| Centimetres | 11.4 × 16.2 | 32.4 × 45.8 |
| Aspect ratio | 1:1.42 | 1:1.41 |
| Area | 184.7 cm² | 1483.9 cm² |
Which is bigger
C3 is 8 times the area of C6. 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.
C3 is 210 mm wider than C6. C3 is 296 mm taller.
Printing one on the other
A C6 page fits inside C3 whole — print it at 100% and you get a 105 mm border down each side and 148 mm top and bottom.
| You want | Set the print scale to | Leaves |
|---|---|---|
| C6 artwork on C3 paper | 282.7% | 1.7 × 0 mm margin |
| C3 artwork on C6 paper | 35.2% | 0 × 0.9 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
The proportions differ: C6 is 1:1.42 and C3 is 1:1.41. 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 1.7 mm of unwanted margin.
