Tips before measuring your size

Your finger size changes throughout the day, so it is best to measure it at the end of the day when the size is largest.

If you are between sizes, we recommend choosing the larger size.

Please note that the left and right hand sizes are different.

How to know your ring size

The most reliable method is to ask for your size at a jewelry store, they have the appropriate tools to measure fingers and usually do it for free.

If you prefer, you can use a ring you already have and measure the inner diameter with a ruler or tape measure. You can see an example below. Compare this measurement to our size guide.
