— The most accurate way of finding out your ring size is to have your finger or a ring of the correct size measured by a professional jeweller, most high street jewellers would be happy to do this for you.
— Your finger size can change during the day, the best time to measure is at the end of the day when your fingers are at their largest. Do not measure when your hands are cold as your fingers could be up to half a size smaller than usual! Measure a few times throughout the day before deciding.
— A wider band will feel tighter than a narrower band. When purchasing a particularly wide band, I recommend choosing a full size larger than your normal ring size.
— Your ring should fit your finger comfortably: there should be a bit of resistance and be snug enough not to fall off, but loose enough to slide over your knuckle with a gentle twist.
