The complete guide to Indian ring sizes 1 to 26 — diameter in mm, circumference, and international conversions for US, UK, EU & Japan.
An Indian ring size chart is a standardised reference guide used by Indian jewellers, goldsmiths, and customers to identify the correct ring size based on the inner diameter or circumference of the finger. Unlike the US or UK sizing systems, India uses a numerical scale from 1 to 26, where each number directly corresponds to a specific inner circumference measured in millimetres — making it one of the most straightforward sizing systems in the world.
In India, rings are worn for every occasion — from everyday gold bands and diamond engagement rings to traditional Anamika rings, mangalsutra rings, and Navratna jewellery. Getting the right size is essential for both comfort and safety. A ring that is too tight can restrict blood circulation, while one that is too loose risks slipping off unnoticed. The Indian ring size chart removes all guesswork by matching your exact finger measurement to the correct size number.
This complete guide covers all 26 Indian ring sizes with diameter in mm, circumference in mm and inches, international conversions for US, UK, EU and Japan sizes, and a free ring size calculator — so you can find your perfect fit from home before visiting any jeweller.
