• 210 mm × 297 mm

A Paper Sizes in Use

A4 is the most familiar paper size for letters and correspondence in India. Its convenient size makes it ideal for various types of documentation, including letters, invoices, and reports.

Conversely, doubling an A-sized paper increases its size while maintaining the same aspect ratio. For example, doubling an A4 results in an A3 (297 mm x 420 mm).
