Printing one on the other

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: Legal is 1:1.65 and ARCH A is 1:1.33. 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 43.5 mm of unwanted margin.
