A1 vs ANSI D
| A1 | ANSI D | |
|---|---|---|
| Millimetres | 594 × 841 | 558.8 × 863.6 |
| Inches | 23.39 × 33.11 | 22 × 34 |
| Centimetres | 59.4 × 84.1 | 55.9 × 86.4 |
| Aspect ratio | 1:1.42 | 1:1.55 |
| Area | 4995.5 cm² | 4825.8 cm² |
Which is bigger
A1, by 3.5% in area. A1 is 35.2 mm wider than ANSI D. ANSI D is 22.6 mm taller.
Printing one on the other
Neither sheet fits inside the other at full size: A1 is the wider of the two while ANSI D is the taller, so each overruns the other on one edge. Whichever way you go, something has to scale or crop.
| You want | Set the print scale to | Leaves |
|---|---|---|
| A1 artwork on ANSI D paper | 94.1% | 0 × 72.4 mm margin |
| ANSI D artwork on A1 paper | 97.4% | 49.8 × 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: A1 is 1:1.42 and ANSI D is 1:1.55. 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 72.4 mm of unwanted margin.
Frequently asked questions
