A well fitting ring should go over your knuckle with a slight push, and sit comfortably on your finger without pinching the skin.
We advise that you get your ring size measured at your local jewellery shop. Please tell the jeweller if you intend to buy a narrow or wide band, as this affects the size. Avoid getting your finger measured when your hands are much warmer or colder than normal, as this can also influence ring size.
An alternative method is to find a ring that fits that finger, make sure it is perfectly round, and use a very sharp pencil to draw inside the ring as close to the band as possible. Take the diameter and use the table here to determine the ring size.
Remember your right and left hand will be different sizes so be sure to get the measurement for the correct finger!
