Major Indian jewelry brands like Tanishq, Kalyan Jewellers, GRT, and Giva generally adhere to the standard Indian numerical scale (1-30). However, because many traditional Indian rings are wider bands or ornate temple jewelry, they often recommend sizing up by half a size for comfort.
The average ring size for women in India is between 12 and 14 (US sizes 6 to 7). For Indian men, the average size ranges between 18 and 22 (US sizes 8 to 10).
