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 C5 | C5 onto C4 |
|---|---|---|---|
| Width | 33.5 mm (1.32 in) each side | C4 loses it | blank band |
| Height | 47.5 mm (1.87 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:
| C5 to fit C4 | 141% | fills the sheet, nothing cropped |
|---|---|---|
| C4 to fit C5 | 71% | fills the sheet, nothing cropped |
Both are one halving apart on the 1 : √2 series, so these are the copier presets and nothing is distorted or lost.
