How to measure your ring size at home

You do not need a jeweller’s mandrel. A thread, a ruler and two minutes will get you within half a size, which is close enough for almost every ring.

Inner diameter is the number to trust when you compare rings, because it does not change with how a band is shaped. Your matched size is highlighted as you use the calculator above.

Diameter figures follow the Indian scale published by leading Indian jewellers. US sizes are shown to the nearest half size, which is how US rings are sold. EU sizes follow ISO 8653, where the size number is the inside circumference in millimetres.

Women’s ring size chart

Most women in India wear between Indian size 10 and 16 on the ring finger, with 12 and 14 the most commonly ordered. That range covers roughly 15.9 mm to 17.9 mm of inner diameter, or US 5½ to US 7½. Smaller fingers, and the little finger on either hand, usually fall between Indian 6 and 10.

Men’s ring size chart

Men in India most often wear Indian size 18 to 24, centred on 20 and 22. That is about 18.5 mm to 20.4 mm inner diameter, or US 8½ to US 11. Thumb rings normally sit two to four Indian sizes above whatever you wear on the ring finger.

What is the average ring size in India?

For women, Indian size 12 to 14 is the most frequently ordered range, and size 12 is the single most common. For men, Indian size 20 to 22 does the same job. These averages are genuinely useful for one purpose only — buying a surprise gift with no way to measure. For your own ring, two minutes with a thread beats any average, because finger size varies far more between people than these numbers suggest.

Sizes also drift with the seasons. Fingers in a Delhi or Chennai summer can measure a full size larger than the same fingers in a north Indian December. If you are ordering in peak summer and the ring is for daily wear all year, it is worth measuring once now and once on a cooler evening, then taking the smaller of the two.

How ring sizes are measured in India

Indian ring sizes are a simple numbered scale that runs from 1 to 30. Size 1 has an inner diameter of about 13.1 mm, and each step up adds roughly a third of a millimetre to the diameter, or about one millimetre to the circumference. Because the steps are small, Indian sizes give finer control than the US scale, where one full size is worth roughly two and a half Indian sizes.

This is the same scale used across India, China, Japan and much of South America, which is why an Indian size will often be listed as a Japanese size on international sites. It is not the same as the US numeric scale or the UK letter scale, so a “size 12” ring means something very different depending on which country sold it. Whenever you are unsure, compare the inner diameter in millimetres instead of the size number — millimetres mean the same thing everywhere.

Five mistakes that lead to the wrong ring size

Buying a ring as a surprise

The cleanest trick is to borrow a ring she already wears on the right finger, and measure the inside diameter with the first method above. If you can only borrow it for a moment, press it into a bar of soap or a piece of soft clay and measure the impression later.

Failing that, ask someone whose hands are a similar size to try on a ring you can measure. If you are truly guessing, Indian 12 for a woman and Indian 20 for a man are the safest single guesses — and since we custom-size most rings at no extra cost, a guess is far from final.

One caution worth knowing before you order: once a ring has been resized or altered, it is no longer eligible for return or exchange under our returns and exchange policy. Sizing done before dispatch is free and does not affect that. If you are unsure, message a stylist on WhatsApp before placing the order rather than after.

Sizing toe rings, thumb rings and adjustable styles

Toe rings. Indian toe rings, or bichiya, are normally worn on the second toe and are sized far smaller than finger rings. Most adults fall between Indian size 4 and 10. Measure the toe exactly as you would a finger, with a paper strip at the base, and remember that toes swell more than fingers in the heat. Many traditional silver toe rings are made slightly open at the back so they can be adjusted by hand.

Thumb rings. Thumbs run two to four Indian sizes larger than the ring finger on the same hand, and the difference is wider in men than in women. Never size a thumb ring from a ring-finger measurement.

Adjustable rings. An adjustable band has an open back that flexes across a range of about four Indian sizes. They are forgiving, which makes them a sensible choice for gifting, but they are not infinitely flexible — repeated opening and closing work-hardens silver and will eventually crack it. Set an adjustable ring once and leave it.

How band width and silver affect the fit

A wide band covers more skin and grips more of your finger, so it feels tighter than a thin band of the same measured size. For any band wider than about 6 mm — most statement rings, signet rings and broad oxidised bands — go one Indian size up from your measured size. For a fine 2 mm band, measure and order exactly.

Comfort-fit bands, which are domed on the inside rather than flat, slide over the knuckle more easily and usually run about half a size large. If you are moving from a flat band to a comfort-fit one in the same size, expect it to feel looser.

Sterling silver itself does not stretch or shrink in normal wear. What it does do is take on a patina over time, and it can be polished back — see our silver care guide for the routine.
