Which is bigger

B3 is 16 times the area of B7. 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.

B3 is 265 mm wider than B7. B3 is 375 mm taller.

Printing one on the other

A B7 page fits inside B3 whole — print it at 100% and you get a 132.5 mm border down each side and 187.5 mm top and bottom.

B3 artwork on B7 paper	24.9%	0 × 0.4 mm margin
B7 artwork on B3 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

Both sheets have the same 1:1.42 proportions, so artwork scales between them without any cropping or extra margin — only the size changes.
