Measuring your finger
- Your ring should fit comfortably — snug enough not to fall off, but loose enough to slide over your knuckle.
- Measure at the end of the day when your fingers are warm. Fingers are smaller in the early morning and when cold.
- Measure 3–4 times to rule out an inaccurate reading.
- Avoid using string or paper — they stretch or twist and give an inaccurate measurement.
Measure a ring you own
Take a ring that already fits the intended finger and measure the inside diameter in millimetres. Match it to the closest diameter in the chart below to find your Indian size. If you fall between two sizes, choose the larger one.

Diameter is the straight-line distance across the inside of the ring; circumference is the distance around the inside. Conversions follow the international ring size standard.
