Which is bigger
A6 and A7 are one step apart in the A series, so one is exactly twice the other. Two A7 sheets side by side make an A6, and folding an A6 in half across its long edge gives two A7. 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.
A6 is 31 mm wider than A7. A6 is 43 mm taller.
Printing one on the other
A A7 page fits inside A6 whole — print it at 100% and you get a 15.5 mm border down each side and 21.5 mm top and bottom.
| You want | Set the print scale to | Leaves |
|---|---|---|
| A6 artwork on A7 paper | 70.5% | 0 × 0.7 mm margin |
| A7 artwork on A6 paper | 141% | 0.7 × 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: A6 is 1:1.41 and A7 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 0.7 mm of unwanted margin.
Frequently asked questions
What is the difference between A6 and A7?
A6 is 105 × 148 mm and A7 is 74 × 105 mm. A6 is the larger of the two by 100% in area.
