Place the order by selecting the “Free Sizing Kit” option. We will send you a sizing kit before your Leep Ring ships.
When the sizing kit arrives, test the sizes on your preferred finger. For best performance and accuracy we recommend the index, middle or ring finger. Once you have chosen a size, wear it for at least 24 hours, including when you sleep.
Once you are sure your test ring is comfortable, go to “My Orders” and submit your chosen size. If you do not have a Leep account, please click here and sign up using the email you used to place the order.

The Leep Ring can be worn on either hand. For optimal accuracy, we recommend wearing it on your index finger, middle or ring finger.
When wearing the ring, ensure the sensors are facing palm side up (under the engraved “L”) and does not rotate easily. Ensure the ring sits comfortably but securely. Try one size up and down to be sure.


Once you’ve chosen your perfect size, try wearing it for 24 hours (including when you sleep). Your fingers will naturally expand and contract throughout the day due to temperature and activity, and a good fit should stay securely and comfortably in place without any rotation.
