Unsure which size to choose?
Use the calculator to find your size, or check the table if you already know a measurement.
Measure straight across the inner opening of a ring that already fits you.
Please enter a measurement between 12 and 24 mm.
The size is a guideline, with an uncertainty of about ±0.5 size. If you're between two sizes, we recommend choosing the larger one. Fingers swell in warmer temperatures. Don't measure fingers that are too cold or too warm, as this can give a misleading measurement.
| Diameter (mm) | Circumference (mm) | EU / DK | UK / IE | US |

Use a string or strip of paper
Wrap a string around the finger where the ring should sit. Mark where it meets, and measure the length in mm - that's your circumference. Choose "circumference" in the calculator.
Measure a ring you already have
Measure the inner diameter (straight across the hole, not around it) of a ring that already fits well. Choose "diameter" in the calculator above.
Best time to measure
Fingers swell in heat and shrink in cold. Measure preferably in the evening, at room temperature, and avoid measuring right after exercise or in cold weather.
If in doubt, feel free to stop by one of our stores and get your size measured.
Print a ruler at true size. Use it either to measure a string wrapped around your finger, or cut it out and measure directly on a ring you already have.
Already have a ruler at home? Then you don't need to print anything - just measure directly with it, the same way as described in Method A and B below.
- Click "Print measuring tape" and select 100% / Actual size in your printer's scaling - not "Fit to page".
- After printing: place a payment card (or another standard-size card, e.g. a health insurance card) in the dashed box on the printout - it should fit edge to edge. If it doesn't fit, adjust your printer's scaling and print again.
Method A: Measure a string
- Take a string, a thread, or a thin strip of paper. Wrap it around the finger where the ring should sit, and mark where it meets.
- Lay the string flat along the printed ruler with one end at 0, and read the mm value at your mark.
- Enter the mm value under "I've measured the circumference" in the calculator above.
Method B: Measure a ring you already have
- Cut out the ruler along the edge.
- Place the ring on the ruler, and measure the inner opening straight across the hole (not around it) on the mm scale.
- Enter the mm value under "I know the diameter" in the calculator above.
The on-screen view below is not to correct scale - only the actual printout is accurate for measuring.
Ditur ring measuring tape
Print without scaling (100% / Actual size). Check the box below with a payment card before measuring.
should fit edge to edge
Method A: Wrap a string around your finger, mark where it meets, and lay it flat against the ruler above to read the mm value - enter it under "I've measured the circumference" in the calculator. Method B: Cut out the ruler, place a ring you already have on it, and measure the inner opening directly - enter it under "I know the diameter" in the calculator.
