A0 paper size is a big printing format that was established in 1975 by the ISO 216 international standard.
A0 sized paper has an area of nearly 1m² – 0.999949 m² to be precise. These days, professionals across a wide range of industries, including publishing and construction, use this popular paper size. Discover the dimensions, the primary characteristics and the different uses of this paper format below.
Different paper forms in the A series measured in millimeters.
A0 paper dimensions.
The dimensions of an A0 paper are 841 x 1189 mm, or 84.1 x 118.9 cm, or 33.1 x 46.8 inches. Owing to its size, A0 is frequently used for exhibitions, banners, and outdoor marketing.
An A0 sheet of paper is equivalent to:
- two sheets of A1
- four sheets of A2
- eight sheets of A3
- 16 sheets of A4 and so on.
A0 paper is divided in half, and the height of the resulting A1 sheet is determined by taking the width of the A0.
| Format | Width x Height (in mm) | Width x Height (in cm) | Width x Height (in inches) |
| A0 | 841 x 1189 | 84.1 x 118.9 | 33.1 x 46.8 |
| A1 | 594 x 841 | 59.5 x 84.1 | 23.4 x 33.1 |
| A2 | 420 x 594 | 42 x 59.4 | 16.5 x 23.4 |
| A3 | 297 x 420 | 29.7 x 42 | 11.7 x 16.5 |
| A4 | 210 x 297 | 21 x 29.7 | 8.3 x 11.7 |
| A5 | 148 x 210 | 14.8 x 21 | 5.8 x 8.3 |
| A6 | 105 x 148 | 10.5 x 14.8 | 4.1 x 5.8 |
| A7 | 74 x 105 | 7.4 x 10.5 | 2.9 x 4.1 |
| A8 | 52 x 74 | 5.2 x 7.4 | 2.0 x 2.9 |
| A9 | 37 x 52 | 3.7 x 5.3 | 1.5 x 2.0 |
| A10 | 26 x 37 | 2.6 x 3.7 | 1.0 x 1.5 |
The A series, which has 10 sub-groups ranging from paper size A0, the largest on the scale, to A10, the smallest, is likely the most well-known paper format.
The German scientist Lichtenberg first described the proportions between the width and height of A series sizes in 1786. However, Porstmann and the German standard DIN 476 did not adopt this −2 aspect ratio until 1922.
- Height for every size in the A series is equal to width x √2.
Common uses of A0 paper.
Although A4 paper is arguably more familiar to and frequently used by most of us, A0 size paper sheets are as vital for a number of diverse uses, such as:
- Technical drawings
- Posters
- Flip-charts
- Blueprints
A0 is often useful for technical design and is most frequently used in reprography or print businesses. This is because it makes it easier for the unaided eye to comprehend the size of a large-scale undertaking.
Because A0 paper’s huge dimensions enable the creation of an eye-catching poster or display to promote an impending event or product release, printing on this paper is also quite prevalent in marketing and advertising.
Printing with A0.
Large format printers known as ‘plotters’ are typically used to print technical documents in A0 format. With high-performance equipment, the results can produce excellent quality in both black & white and full colour.
However, in order to print an image on A0 paper, it must generally be 841 mm x 1189 mm in 150 dpi (dots per inch) or 300 ppi (pixels per inch). Remember that a 3 mm bleed margin is typically needed around the document in order to allow for further cutting without compromising the image.
Frequently asked questions.
Is A0 the biggest sized paper?
No, the largest paper size that is offered is not A0. A0 is smaller than B0 and C0, as well as 2A0 and 4A0. Despite not being defined by ISO 216, 4A0 and 2A0 are frequently utilized when extremely large paper sizes are required. These two forms are based on the DIN 476 standard from Germany.
Is paper size A0 or A1 larger?
A0 is larger than A1, yes. Specifically, A0 measures 841 x 1189 mm, while A1 measures 594 x 841 mm. It’s crucial to keep in mind that the A paper series has larger paper sizes the lower the number. The largest paper size in the series is therefore A0, followed by A1, A2, etc.
