Tips For Measuring Your Ring Size

  1. Your finger size can change throughout the day, so it is a good idea to measure at the end of the day when your fingers are at their largest. Do not measure when your hands are cold; your fingers will be at least half a size smaller.
  2. Rings with a particularly thick band will feel tighter than a thin band; in these cases, we recommend buying a full size larger than your normal ring size.
  3. If you’re buying a gift, the best way - but not always the easiest way - is to borrow his or her ring (from the correct finger) and use the ring sizer guide on the left to determine its size.
  4. Your ring should fit your finger comfortably; it should, of course, be snug enough so that it will not fall off, but loose enough to slide over your knuckle.
  5. If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.
