The easiest way to do this is to use a measuring tape. Place the measuring tape around the base of the finger, where you would like the ring to sit. Compare this measurement (inside circumference) to the chart above to determine your ring size. Alternatively, try our measurement guide.
Measure your ring size at the end of the day when your fingers are at their largest.
Make sure your hands are nice and warm. If you’re cold, your finger may be up to half a size smaller than normal.
If using a measuring tape, or a ring sizer, make sure it fits comfortably enough not to slip off, but loose enough to slide over your knuckle.
If buying a thicker ring we would recommend you go up a size.
