The A3 ISO paper size is 11.7 in. x 16.5 in. (297 mm x 420 mm.) The ISO standard has been adopted by all countries in the world except the United States and Canada.
The dimensions of an A3 size paper are 297 mm x 420 mm or 11.7 in x 16.5 in. It is twice the size of an A4 paper.
The size of A3 paper is 420mm x 297mm
No, A3 size pages are twice the size of A4 size pages. A3 measures 297 x 420 mm, while A4 measures 210 x 297 mm. So, one A3 page is equal to four A4 pages in size.
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.

ISO paper size standards are set by the International Organization for Standardization (ISO). The most commonly used ISO paper sizes are A4 (210 x 297 mm) and A3 (297 x 420 mm), with larger sizes denoted by increasing the A number. The standards provide consistency and compatibility in paper sizes for various uses, such as printing and design.
A5 paper is: 148 × 210 mm 14.8 cm by 21.0 cm 5.83" X 8.27" (notepad size). ----------------------------------------------------------------------------- Take a piece of A4 paper (the size that goes into a normal computer printer) and fold this in half so that the two shortest edges are together. The folded piece of paper is A5 in size. Yes half of A4 is A5 but the photocopy or printer paper used in USA & Canada is not A4 size but 8.5x11".
A4 paper is exactly half the size of A3, and they both have the same aspect ratio. So A4 --> A3 is an enlargement. Most photocopiers use A4 as standard. You need a larger photocopier to copy onto A3. The photocopier will usually offer A4 --> A3 as an option.
