Method 1: Measure your finger

Ideal if you do not own a ring that already fits the intended finger.

1. 1
   Cut a thin strip of paper or use a piece of string.
2. 2
   Wrap it around the base of your finger where the ring will sit and mark the point where the ends overlap.
3. 3
   Lay the paper or string flat and measure the length with a ruler in millimetres (mm).
4. 4
   Compare your measurement with a ring size chart to find the closest size.

If you are creating a ring stack, consider where on your finger each ring will sit—higher on the finger often requires a slightly smaller size.

Method 2: Measure an existing ring

Perfect when you already have a ring that fits the intended finger well.

1. 1
   Select a ring that fits comfortably on the finger you have in mind.
2. 2
   Measure the inner diameter of the ring in millimetres using a ruler or caliper.
3. 3
   Use a ring size chart to convert the inner diameter to your ring size.

Ring sizing tips

• Measure your finger at the end of the day when it is at its largest.
• Avoid measuring when your hands are very cold or very warm, as this can affect the result.
• Ensure the size allows the ring to pass over the knuckle but still sit snugly without feeling tight.
• Remember that fingers on your dominant hand are often slightly larger than on your non-dominant hand.
