| You want | Set the print scale to | Leaves |
|---|---|---|
| B5 artwork on C5 paper | 91.6% | 0.8 × 0 mm margin |
| C5 artwork on B5 paper | 108.6% | 0 × 1.2 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: B5 is 1:1.42 and C5 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 0.8 mm of unwanted margin.
