In millimeters the A0 paper size is 841mm by 1189mm.
In inches the A0 paper size is 33.1 × 46.8 in.
In the standardised paper measurement system A0 is 1189 millimetres x 841 millimetres.
The standard size of paper used for computer printouts and other uses is A4. A4 paper is 210 × 297 mm. It has an area of 1/16 metres². It is one of a series of paper sizes starting with A0, which has an area of 1 square metre.
Paper is measured along a scale preceded by A. A0 is 841mm by 1189mm, fold and cut in half, you will have A1 and so on.
A0 paper is 46.8 x 33.1 in.
210 × 297 mm. A4 is the standard size for most countries, excluding the US, Canada and a few others.A4 is one of a series of paper sizes, starting with A0. A0 has an area of 1 m². If you fold A0 into two you get A1, and so on.All sizes in the A-series have the same ratio of length/width, which is the square root of 2.
The International Standard for paper sizes defines A0 as a sheet of paper that has an area of 1 metre2 and whose length is sqrt(2) times its width. So A0 is approx 841mm*1.189mm.A1 is the size of an A0 sheet folded in half lengthwise: 595mm * 841mmA2 is the size of an A1 sheet folded in half lengthwise: 420mm * 595mmA3 is the size of an A2 sheet folded in half lengthwise: 297mm * 420mmA4 is the size of an A3 sheet folded in half lengthwise: 210mm * 297mmThe size of an A4 sheet is 0.0625 metre2 or 2-4metre2.If you took 2x sheets of size Ax you would have 1 sq metre of paper.
16 pages of A4 fit into an A0
The A series paper has a height to width ratio of square root 2 to 1 (1.4142:1) A sheet of A0 has an area of one square metre. To fit the ratio its sides are 841 millimetre x 1189 millimetre. Each sheet in the series is half the size of the previous sheet; the height of A1 would be the width of A0, the width of A1 is half the height of A0, 594 mm x 841 mm. A3 has a height of 420 millimetres and a width of 297 millimetres.
The largest paper size commonly used is the ISO A0 size, which measures 841 x 1189 mm (33.1 x 46.8 inches). It is typically used for large format printing and posters.
