How to Measure Your Ring Size
Option 1 – Measure an Existing Ring
-
Choose a ring that fits the intended finger comfortably.
-
Measure the inside diameter of the ring using a ruler or digital caliper.
-
Match the measurement to the chart above.
Option 2 – Measure Your Finger
-
Wrap a thin strip of paper or a piece of string around the base of your finger.
-
Mark where the ends meet.
-
Measure the length with a ruler in millimetres (mm).
-
Compare the measurement with the Inside Circumference column in the chart.
Tips for the Best Fit
-
Measure your finger at the end of the day, when it is at its largest.
-
Avoid measuring when your hands are cold, as fingers tend to be smaller.
-
If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between.
-
If you're between sizes, we generally recommend choosing the larger size for greater comfort.
-
Finger size can vary slightly due to temperature, hydration and time of day.
