Ring Size Measurement Guide
Measuring Your Ring Size at Home
String or Paper Method:
- Cut a thin strip of paper or use a piece of string.
- Wrap the string or paper around the base of your finger. Ensure it’s not too tight or too loose.
- Mark the point where the end meets the rest of the string/paper.
- Measure the length of the string or paper with a ruler in millimeters (mm).
- Use the measurement to find your ring size from the charts below.
Ring Size Chart:
- Use a printable ring sizer or a ring size chart.
- Place a ring that fits you over the circles in the chart until you find the one that matches the inner diameter of the ring.

Tips for Accurate Measurement
- Measure your finger at the end of the day when it is likely to be largest.
- Ensure your finger is at a normal temperature — fingers can shrink or expand when cold or hot.
- If your knuckle is much larger than the base of your finger, take two separate measurements and choose a size in between.
- For a more accurate measurement, consider getting sized at a jewelry store.
