Printing one on the other
Neither sheet fits inside the other at full size: JIS B6 is the wider of the two while Envelope No. 11 is the taller, so each overruns the other on one edge. Whichever way you go, something has to scale or crop.
| You want | Set the print scale to | Leaves |
|---|---|---|
| JIS B6 artwork on Envelope No. 11 paper | 89.3% | 0 × 101 mm margin |
| Envelope No. 11 artwork on JIS B6 paper | 69.1% | 49.1 × 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
The proportions differ: JIS B6 is 1:1.42 and Envelope No. 11 is 1:2.31. 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 101 mm of unwanted margin.
