How to Measure Your Ring Size at Home

If you don’t know your size and don’t have a ring to reference, you can measure your finger using a simple method.

What You’ll Need

  • A thin strip of paper or a piece of string

  • A pen

  • A ruler (millimeters)

Steps

  1. Wrap the paper or string firmly around the base of your finger. It should feel secure, not loose and not too tight.

  2. Mark where the ends meet.

  3. Measure the length in millimeters.

  4. Match that measurement to the closest circumference in the chart above.

 


 

Helpful Tips

  • Measure your finger when it is warm. Cold fingers tend to measure smaller.

  • If you fall between sizes, choose the size closest to your measurement.

  • Wider bands fit more snugly. Consider sizing up for bands wider than 4mm.

  • For very thin bands, sizing down slightly may provide a better fit.

  • If you have a prominent knuckle, measure both your knuckle and the base of your finger. Choose a size between those two measurements so the ring slides over comfortably but sits securely.

A well-fitted ring should feel secure without pinching. You should be able to remove it with slight resistance.
