Ring Size Guide

A lot of people ask us about their ring size here at Prometéme . Since we sell almost all of our rings online, our customers don’t get a chance to try a ring on before they buy it. That’s why we offer a ring size guide that can help you get the right fit.

Prepping for Measurement

Before you begin taking your measurements, pick the finger on which you want to wear your ring. The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size.

Ensure that your finger is at its normal size before taking a measurement. Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food, medications, or illness can cause finger swelling.

How Do I Measure My Finger for a Ring?

If you have access to a printer, we highly recommend using our printable ring sizer, as it is the surest way to get an accurate measurement.

If you do not have access to a printer, you can use either a string or a strip of paper to measure your finger or a ring you already own. See the charts below for further instructions on these sizing methods.

Do You Have a Printable PDF Ring Size Guide?

Yes we do! Our printable PDF ring size guide is a more accurate way to get a proper measurement.

How do I use String as a Ring Sizer?

  1. Take a piece of string, ribbon, thread, or a thin strip of paper and wrap it around your finger, close to the knuckle.
  2. With a pen, carefully mark the spot where the string overlaps with its end and either hold it up to a ruler that has millimeter measurements, or to the graphic below.
  3. Use the chart to determine your ring size.

How do I Find What Ring Size I am Using With a Ring That I Own?

With a ruler and the chart below. Use the ruler to measure the diameter of the inside of the ring, then look up the measurement on the chart to find the corresponding ring size.
