Determining your ring size by measuring your finger

Measure your finger at the end of the day. Do not measure your finger when the room temperature is hot or cold.

Remember that your two hands differ slightly in size; a ring worn on a finger of the left hand will not be a perfect fit for the same finger on the right hand.

Make sure that the chosen size leaves enough room for the ring to pass easily over the knuckle.

To measure your finger you can use a string. Measure the circumference of your finger and mark the string. Then measure the string length against a ruler or tape measure in mm. This measurement corresponds to the size of the ring.

If you are hesitating between two sizes, choose the larger size.
