Standard paper sizes, in mm and cm
The full A series, plus the usual sizes for business cards, flyers, posters and roll-ups.
ISO A formats start at A0, a sheet with an area of one square metre. Each next size is the previous one halved along the long edge, so the proportion stays the same and a layout designed for A4 scales without changing the composition.

| A0 | 841 × 1189 mm | 84.1 × 118.9 cm | large posters, technical drawings |
| A1 | 594 × 841 mm | 59.4 × 84.1 cm | window posters, indoor boards |

How to specify a size correctly
- Always give the final trimmed size, not the sheet size.
- The first number is the width, the second the height, so portrait or landscape is unambiguous.
- For unusual sizes, check that they fit the press sheet economically, otherwise you pay for paper you throw away.
