Ring sizing tips
Choose the Correct Finger Size
Measure the finger on which you plan to wear the ring. If needed, round to the nearest whole millimetre and choose a size that comfortably slides over your knuckle without feeling too tight.
Measure at Different Times of the Day
Finger size can vary depending on temperature, hydration, and time of day. For the most accurate result, take measurements multiple times throughout the day.
If You’re Between Sizes
If your measurement falls between two sizes, we recommend choosing the slightly larger size for greater comfort.
Tips for Stackable and Wide Rings
For stackable rings or rings with a wider band, consider selecting one size larger than your usual fit to ensure added comfort.
