- a piece of string
- a marker
- a ruler with mm or millimeter markings on it
Wrap the string around the largest part of your finger, this in most cases is the base of the finger in which you want to wear the ring, however in some cases this is the knuckle above where you want the ring. Mark the string where it meets on your finger and measure it with the ruler, make sure to measure it using the mm or millimeter settings.
Want to buy a ring as a gift and you are not sure of the size. Sneak a ring that you know fits and slide it over a tapered candle. follow the directions above and measure the candle where the ring stops on the candle.
Tip: finger sizes can change during the course of the day. To ensure the best fit measure your finger at the end of the day. Or measure a couple of times during the day and order your ring in the largest size that you measured.
