Measure Your Ring Size at Home
Measure an Existing Ring
If you already have a ring that fits well on the intended finger:
- Place it on a ruler and measure the inside diameter (in millimeters).
- Use the chart below to find the corresponding ring size.
Measure Your Finger
If you don’t have a ring to measure:
- Cut a thin strip of paper or use a piece of string.
- Wrap it around the base of your finger. It should be snug but not tight.
- Mark where the ends meet and measure the length in millimeters.
- This is your finger circumference. Use the chart below to determine your size.
Important Tips:
- Measure your finger at the end of the day, when it's likely to be at its largest.
- Avoid measuring when your hands are cold, as this can give a smaller reading.
- If you're in between sizes, we recommend sizing up for comfort.

Additional Sizing Advice
- Wider bands may feel tighter than thinner ones. If you're buying a wide ring, consider going half a size up.
- Stackable rings should allow some space between each band. Don't size down too much.
- Finger sizes can vary slightly between hands. If you're buying for your dominant hand, you may need a slightly larger size.
