Find Your Ring Size
The most reliable and accurate way to be measured is by a professional jeweller. Please note that some companies may charge a small fee for their time.
Measuring for your ring:
- Measure a ring you already own.
- Select the ring that matches the desired finger.
- Measure the internal diameter of the ring in millimetres (mm) - the inside diametre should not include the ring itself, just the space inside the ring.
- I have created a printable ring sizing guide. Please ensure you’re printing this at 100% scale and not using it on a mobile device.
Useful information:
- With a very wide ring you may need a size larger. Finer / thinner rings like thin stacking rings / wedding bands may not need to be as big.
- A good-sized ring fits snugly and gives a little resistance when taken off.
