How the Ring Size Calculator Works
The calculator uses your measurement to find the nearest entry in the same size chart used throughout Digital Ring Sizer, then shows equivalent India, US, UK and EU sizes.
Diameter vs Circumference
Diameter is the straight distance across the inside of a ring. Circumference is the distance around a finger or ring. Use the measurement you can take most reliably.
How to Get a Better Ring Size Estimate
- Measure more than once at a comfortable temperature.
- Do not squeeze a paper strip too tightly.
- Use an existing ring when possible.
- Confirm expensive jewellery with a professional jeweller.
