In order to get reliable measurements, we suggest you use ribbon ore twine: wrap it around your finger/wrist and use ruler to gauge the length in millimeters/centimeters; then check following directions regarding circumference/size.
Ring: we suggest to measure the length bearing in mind that the ring is usually worn where your finger joins your hand. Use the twine wrapping it around your finger, then measure its length with a ruler.
Bracelet: to select the bracelet size we suggest to measure the circumference wrapping the twine just below your wrist. Measure the length with the ruler, then add about 5mm to calculate your exact size.
