How To Measure Ring Size With String, Paper & Ruler
1. Wrap string or paper around the base of your finger.
2. Mark the point where the ends meet with a pen.
3. Measure the string or paper with a ruler (mm) to get the circumference then divide by 3.14 (or Pi) to get the diameter.
4. Pick the closest measurement on the ring size chart to find your ring size.
*TOP TIP*
Measure your ring size at the end of the day when your fingers are warm. Finger size changes depending on the time of day and the weather, and your fingers are actually smaller in the early morning and in cold weather. Also, keep in mind that fingers on your dominant hand are usually larger.
