Poster sizes in India: A3, 11 × 17.5, 18 × 23 and 20 × 30

Common poster sizes in India in inches and mm, which one to use for shop windows, notice boards and events, and real offset poster prices.

Poster sizes in India come from the sizes of the big paper sheets printers buy. That is why you hear sizes like 18 × 23 and 20 × 30 rather than international A-sizes.

Design tips for posters

  • One big message that can be read from 3 metres away.
  • Your phone number or address large enough to read from a distance.
  • High-resolution photos: a poster shows every pixel.
  • Leave a 5 mm safe margin; walls and frames hide the edges.

Design a poster online and see it framed on a wall before you order.
