Which is bigger
B7 is 8 times the area of B10. They are 3 steps apart in the B series and each step halves the sheet, so the multiple is two to the power of 3. The number in the name going up while the sheet goes down is why this has to be asked rather than read off.
B7 is 57 mm wider than B10. B7 is 81 mm taller.
Printing one on the other
A B10 page fits inside B7 whole — print it at 100% and you get a 28.5 mm border down each side and 40.5 mm top and bottom.
| You want | Set the print scale to | Leaves |
|---|---|---|
| B7 artwork on B10 paper | 35.2% | 0 × 0 mm margin |
| B10 artwork on B7 paper | 283.9% | 0 × 0.1 mm margin |
These are the numbers for the "custom scale" box in a print dialog. "Fit to page" computes the same thing, but knowing the figure tells you in advance whether the result will look deliberate or accidental.
Why the shapes matter
Both sheets have the same 1:1.42 proportions, so artwork scales between them without any cropping or extra margin — only the size changes.
