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 | B5 onto B6 | B6 onto B5 |
|---|---|---|---|
| Width | 25.5 mm (1 in) each side | B5 loses it | blank band |
| Height | 37 mm (1.46 in) each end | B5 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:
| B6 to fit B5 | 141% | fills the sheet, nothing cropped |
|---|---|---|
| B5 to fit B6 | 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.
