So 297/2 = 148, this gives us an A5 size of 148mm x 210mm, exactly half the size of and A4 sheet.
Herein, is A4 bigger than A5?
If you cut a sheet of A4 paper in half along its longest side, you will end up with
| Format | Width x height – inches | Width x height – mm |
|---|---|---|
| A4 | 11.7 x 8.3 inches | 297 x 210 mm |
| A5 | 8.3 x 5.8 inches | 210 x 148 mm |
| A6 | 5.8 x 4.1 inches | 148 x 105 mm |
In this regard, is A5 smaller the A4? A1, A2, A3, A4) measurement is determined by halving the dimensions of the preceding one. For example the most commonly used paper size is A4 (297mm x 210mm) and the next paper size is A5 (210mm x 148.5mm) which is equal to half of the A4 dimensions.
