Which is bigger

B6 and B7 are one step apart in the B series, so one is exactly twice the other. Two B7 sheets side by side make a B6, and folding a B6 in half across its long edge gives two B7. That is what the series is for, and it is why the scale factors below come out at 70.7% and 141.4% — one over the square root of two, and the square root of two.

B6 is 37 mm wider than B7. B6 is 51 mm taller.

Printing one on the other

A B7 page fits inside B6 whole — print it at 100% and you get a 18.5 mm border down each side and 25.5 mm top and bottom.

B6 artwork on B7 paper	70.4%	0 × 1.1 mm margin
B7 artwork on B6 paper	140.8%	1.1 × 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 B7 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 1.1 mm of unwanted margin.
