What Is Lost Printing One on the Other

At 100% scale, both centred, nothing resized. A positive figure on the wider or taller side is cropped; on the other it is a blank margin.

Scale-to-Fit Percentages

The figure to type into a printer or PDF dialog to scale one to fit inside the other:

C6 to fit C4200%leaves a thin border on one pair of edges
C4 to fit C650%leaves a thin border on one pair of edges

The two share the 1 : √2 shape but are not one halving apart, so a fit-to-page scale still leaves a small border.
