Our sizing recommendation
Use the kit for your RingConn generation and wear the sample for at least 24 hours, including sleep and normal activity. RingConn recommends the index finger for best accuracy.
Smart rings contain sensors and have a different inner profile from conventional jewellery. A calibrated jewellery measurement can provide a starting point, but the manufacturer’s own sizing kit is the final authority.
Use the correct RingConn sizing kit.
Check the generation before ordering: smart-ring sizing kits are not universally interchangeable.
