How to Measure Finger for Ring Size
Get Sized at a Jeweler: To ensure the most accurate ring size, we recommend you visit your local jeweler for a professional sizing.
If You are Buying the Ring as a Surprise: 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.
Tips for Measuring a Ring Size: 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.
Size Yourself: Wrap a thin strip of paper or piece of string around the base of the finger you want to measure. With a pen, mark the point on the paper or string where it overlaps, forming a circle on the finger. Measure the length of the paper or string using a flat ruler, from the starting point to the pen mark. Then find the matching size in the chart below.
