A4 Size Paper Ratio
The A4 paper belongs to the ISO 216 standard, which is based on a unique aspect ratio of 1:√2 (approximately 1:1.414).
This ratio ensures that when an A4 sheet is cut or folded in half parallel to its shorter side, the halves also retain the same proportions.
This consistency makes resizing and scaling documents simple, especially for printing, copying, and design work. It’s the defining feature of the entire A-series (A0, A1, A2, A3, A4, etc.).
A4 Dimensions: 210 × 297 mm
Aspect Ratio: 1:√2 ≈ 1:1.414
In practical terms, this means an A4 sheet (210 × 297 mm) can be perfectly scaled up to A3 or down to A5 while keeping its proportions intact. This makes A4 one of the most versatile and widely used paper sizes worldwide.
