Ring Size Guide

Our sizes are based on US sizes. Our size tables will give you a comparative scale of ring sizes from different countries and help you easily convert American sizes to UK, EU or Indian sizes.

Tips for Measuring Your Ring Size:

Your rings should fit comfortably, not too tight, but not too loose either. It should be loose enough to slide over your knuckle and tight enough so that it can’t fall off your finger.

  • Be sure that your fingers are warm; cold can shrink fingers up to half a size.
  • Measure your fingers at the end of the day when they’re largest.
  • Measure your finger size a few times to make sure it’s accurate.
  • If the measurement falls between sizes, choose the larger size.
  • Measure the finger on which you’ll be wearing the ring.
  • Wider rings often feel tighter than thinner ones; for ring widths of 4 mm or more, consider choosing half a size larger.
  • Your ring should sit securely while still being easy to slide over your knuckle.
  • If you have larger knuckles, opt for a slightly bigger size so the ring doesn’t feel too loose on the finger.

Keep in mind the average ring size range for women is between 5 and 7 (US), while sizes commonly range from 8 to 10 (US) for men. If you have no other information available, it’s best to choose between these ranges.

Measure an existing ring with a ruler

Option 1: Measure an Existing Ring:

  1. Choose a ring that fits the intended finger.
  2. Measure the inside diameter in millimetres (mm).
  3. Match it to the conversion chart below.
  4. Alternatively, place the ring on a ruler (as shown in the image) and send us a photo; our team can help you find the correct size.
  5. You may also use a printable ring sizing tool if available to confirm your size.

Tip: When using this method, rings with a wide shank tend to sit more tightly. For bands wider than 3–4 mm, you may not need to size down even if the measurement appears slightly large.

Option 2: Measure Your Finger:

This method has a slightly higher chance of error because thread or paper has thickness and can sink into the skin differently than a metal ring. Repeat the measurement several times for accuracy.

  1. Wrap a thin strip of paper or string around your finger.
  2. Mark where the ends meet.
  3. Measure the length in mm — this is the circumference.
  4. Find the closest size in the chart.

Tips: A thin, narrow strip of paper is preferred. Tape the ends together to make a ring, then slide it over your finger to ensure it moves comfortably over the knuckle. If it’s difficult to slide off, choose one size larger.
