But is possible to measure it yourself also:

1. Wrap a thin strip of paper or piece of string around the base of the finger you want to measure.

2. With a pen, mark the point on the paper or string where it overlaps, forming a circle on the finger.

3. Measure the length of the paper or string using a flat ruler, from the starting point to the pen mark.

4. Then find the matching size in the chart below.


Tips: Don't measure cold fingers, as this is when fingers are the smallest. The best time to measure a finger is at the end of the day when the finger is the largest. Take at least two measurements for accuracy.

Buying for someone else: Borrow one of your partner’s rings and slide it down a tapered candle. Measure the circumference of the candle where the ring stops. Use the chart below to determine the correct ring size.
