Find your perfect fit.
Three ways to find your ring size: measure an existing ring, measure your finger with a strip of paper, or print this page and match your ring to our size circles. Not sure? Request a free ring sizer and we will post it to you.
Use an existing ring
Find a ring that fits your finger well. Place it flat on the table and measure the internal diameter (across the inside of the ring, not the outside). Match that measurement to the table below.
Measure your finger
Cut a thin strip of paper and wrap it snugly around the base of your finger. Mark where the ends meet, then lay the paper flat and measure the length. This is your finger circumference. Find it in the table below.
Use the printable circles
Print this page at 100% scale (no scaling or fit-to-page). Hold your ring over the circles below and find the one that matches the internal diameter of your ring.
Important: Print at 100% with no scaling. Check accuracy by measuring the 10mm reference bar above the chart.

Tips for an accurate fit
- Measure your finger at the end of the day when fingers are slightly larger - this gives the most accurate everyday size.
- Fingers change size with temperature. Cold fingers are smaller; warm fingers are larger. Measure when your hands are warm.
- If you are between sizes, it is generally better to go up rather than down, especially for wider bands.
- Dominant hand fingers are often slightly larger than the other hand. Measure the specific finger you intend to wear the ring on.
- If in doubt, email us to request a free ring sizer - we'll post one out at no charge.
