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 | B1 onto B2 | B2 onto B1 |
|---|---|---|---|
| Width | 103.5 mm (4.07 in) each side | B1 loses it | blank band |
| Height | 146.5 mm (5.77 in) each end | B1 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:
| B2 to fit B1 | 141% | fills the sheet, nothing cropped |
|---|---|---|
| B1 to fit B2 | 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.
