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.
| Axis | Gap | C4 onto C6 | C6 onto C4 |
|---|---|---|---|
| Width | 57.5 mm (2.26 in) each side | C4 loses it | blank band |
| Height | 81 mm (3.19 in) each end | C4 loses it | blank band |
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 C4 | 200% | leaves a thin border on one pair of edges |
|---|---|---|
| C4 to fit C6 | 50% | 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.
