Indian Ring Sizes Explained

Indian ring sizes use a numbering convention that differs from US, UK and EU labels. Use the corresponding millimetre measurements and equivalents as a practical reference, then check the jeweller’s own chart when needed.

Indian Ring Size Chart in Millimetres

Start with an India size if you already have one, or use a diameter/circumference measurement to find its row. The India column is first here so the local label stays easy to compare with the millimetre values.

A mid-range India-first chart example

This example comes from the same shared row set shown in the table above; it is not a separately maintained conversion.

Diameter: 17.2 mm
Circumference: 54.0 mm
India: 14
US: 7
UK: N
EU: 54

A larger India-first chart example

This second row shows that the same chart carries the millimetre measurement and international labels together.

Diameter: 19.1 mm
Circumference: 60.0 mm
India: 20
US: 9
UK: S
EU: 60

How to Measure Your Indian Ring Size

Measure a ring that fits, use a paper strip for finger circumference, or calibrate a phone screen before using the on-screen existing-ring guide.

India to International Ring Size Conversion

Once you have an India label, use its row to compare the corresponding US, UK and EU labels. Check a seller’s own chart when the purchase requires an exact brand-specific fit.

Ring Size Accuracy

Use the chart as an estimate and confirm expensive, custom or non-resizable jewellery with a professional jeweller.
