Indian ring size chart
The Indian scale is a plain number, running from about 1 to 30, and its steps are fine: roughly half a millimetre of inside diameter each, against 0.81 mm for a whole US size. Tanishq, Malabar, Kalyan and GIVA all quote it. The table below places it against the millimetre measurement it stands for.

Derived from ISO 8653. Published Indian conversions differ between sources by about one step, so treat the millimetre column as the fact and the number as its label.
Why Indian sizes move faster than US ones
Two Indian sizes are roughly one US size. That fineness is useful at the bench — a jeweller can work closer to the finger than a half-size scale allows — but it also means a small measuring error moves the Indian number more than it moves the US one. Half a millimetre of diameter is one Indian size and only about half a US size.
It is also why Indian charts published by different jewellers disagree by a step. They are all approximating the same underlying millimetre scale from slightly different starting points. If a shop quotes you a number that is one off what you calculated, that is the reason, and the diameter is what to compare.
Buying gold, and buying online
Gold rings priced by weight are expensive to resize, because resizing changes the weight. That makes the first measurement matter more here than almost anywhere else. Measure a ring that already fits on its inside diameter — with a caliper or a calibrated screen — rather than measuring the finger.
The Indian market also runs two scales side by side. Older catalogues print the UK letter next to the Indian number, and imported or online-first brands often quote US sizes. All three describe the same finger. The international ring size chart puts them in one row, and the brand pages for Tanishq, Malabar, Kalyan and GIVA cover each house in detail.
Getting it right
Three things that move an Indian ring size
- Heat, and the time of day
- Fingers swell considerably in Indian summers. Measure in the afternoon at ordinary room temperature so the ring fits at your largest, not your smallest.
- Wide traditional bands
- A broad gold band presses against more of the finger. Add half a size from about 5 mm of width and a full size from about 9 mm.
- Charts disagree by one step
- Different jewellers publish slightly different Indian conversions. Quote the diameter in millimetres and the ambiguity disappears.
Ordering from elsewhere
The same finger, in another market
Buying from a Gulf store, or shipping from the US? Pick the market and read the local number for the same diameter.
Do not know it? Measure a ring on your calibrated screen — it is the only number here that is not a conversion of another number.
Indian numeric
14
A number from 1 to about 30. Indian jewellers frequently print the UK letter beside it, because both are in daily use.
India. Indian jewellers quote a numeric scale of their own, roughly 1 to 30. Tanishq, Malabar Gold, Kalyan and GIVA all use it, and many print the UK letter beside it. Online-first brands often list US sizes as well, so check which scale a listing means before ordering. Full India ring size chart.
United States. The US numeric scale, sold mostly in half sizes. Quarter sizes exist and a jeweller can cut them, but they are rarely stocked. Full USA ring size chart.
United Kingdom. Letters, in half-letter steps. British hallmarked rings are usually stamped with the letter, so an inherited ring often tells you its own size if you look inside the band. Full UK ring size chart.
Europe. France, Germany, the Netherlands and Scandinavia quote the ISO 8653 number, which is the inside circumference in millimetres. Italy, Spain and Switzerland quote the same measurement minus 40, so a 54 becomes a 14. Full Europe ring size chart.
Japan. The Japanese numeric scale runs #1 to about #27 for the sizes people actually order. Mikimoto, Tasaki and 4°C all use it. Japanese sizes are usually whole numbers only. Full Japan ring size chart.
China. Mainland Chinese listings usually give 圈号 — the inside circumference in millimetres, the same number as EU/ISO. Hong Kong uses a separate numbered scale, and marketplace listings mix both with US sizes. Order by inside diameter in millimetres when a listing does not say which scale it means.
Australia. Australia and New Zealand use the UK letter scale unchanged, so a UK N is an Australian N.
Canada. Identical to the United States. A US 7 is a Canadian 7, with no conversion in between.
Singapore. Singapore retail is mixed: international brands quote US numbers, goldsmiths in the Chinese tradition quote Hong Kong numbers, and British-founded chains quote letters. Ask for the inside diameter in millimetres and you sidestep the whole problem.
Malaysia. As in Singapore, US numbers dominate modern retail while traditional goldsmiths use Hong Kong numbers. Confirm the scale, or the diameter, before you order.
United Arab Emirates. Gulf retail quotes US sizes most often. British-founded chains use letters, and the many Indian gold houses in Dubai use the Indian scale, so the same finger can be quoted three ways along one street.
South Africa. South Africa follows the UK letter scale. Online stores that ship from the United States will quote numbers instead.
Brazil. Brazilian sizes are the inside circumference in millimetres minus 40 — the same arithmetic Switzerland uses. A 54 mm circumference is a Brazilian 14.
Mexico. Mexican jewellers use a local numeric scale that is not the US one, and the published conversions for it disagree with each other. We will not print a number we cannot stand behind, so order by inside diameter in millimetres, or ask the retailer for the diameter of the size they are offering. Large chains and online stores generally quote US sizes.
Questions
Indian ring sizing, answered
What is the average ring size in India?
Around Indian 12 to 14 for women and 20 to 22 for men — roughly US 6 to 6.5 and US 10 to 11. Treat it as the middle of a distribution, not as an answer for any individual.
What is Indian ring size 12 in US?
About a US 6, an inside diameter near 16.5 mm. Indian 16 is close to a US 7¾, and Indian 20 close to a US 9½.
How do I measure ring size at home in India?
Measure the inside diameter of a ring that already fits, on a calibrated screen or with a caliper. Failing that, wrap a 6 mm paper strip round the base of the finger, mark the overlap and measure to the mark — that gives you the circumference directly.
Do Indian jewellers use UK sizes too?
Frequently. Many Indian charts print the UK letter beside the Indian number because both are in daily use. They refer to the same measurement.
Which finger should I measure?
The one the ring will be worn on, on the correct hand. The two hands differ, and the dominant hand is usually slightly larger.
