Printing one on the other

Neither sheet fits inside the other at full size: C5 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.

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: C5 is 1:1.41 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 102 mm of unwanted margin.
