Which is bigger
B6 is 16 times the area of B10. They are 4 steps apart in the B series and each step halves the sheet, so the multiple is two to the power of 4. The number in the name going up while the sheet goes down is why this has to be asked rather than read off.
B6 is 94 mm wider than B10. B6 is 132 mm taller.
Printing one on the other
A B10 page fits inside B6 whole — print it at 100% and you get a 47 mm border down each side and 66 mm top and bottom.
| You want | Set the print scale to | Leaves |
|---|---|---|
| B6 artwork on B10 paper | 24.8% | 0 × 0.4 mm margin |
| B10 artwork on B6 paper | 400% | 1 × 0 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
The proportions differ: B6 is 1:1.41 and B10 is 1:1.42. That difference is why a layout moved between them never quite lines up — scale it to fit one edge and the other is left with 0.4 mm of unwanted margin.
