Standard A Paper Sizes (ISO 216)
The A series paper sizes are defined by the ISO 216 international standard. They are widely used around the world for general printing, office, and publishing purposes (except in North America).
Key Features
- The aspect ratio of all A series paper sizes is 1:√2 (approximately 1:1.414).
- Cutting an A-size sheet in half *parallel to its shorter side* gives the next smaller A size (e.g., cutting A4 in half gives two A5 sheets).
- The base size is A0, which has an area of 1 square meter.
