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 4.0 mm or more, consider choosing half a size larger for a more comfortable fit.
  • 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), 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 chart below.
  4. Alternatively, you can send us an image of the ring placed on the ruler as shown in the image our team will help you find the correct ring size.

Tip: When using this method, you should keep in mind that rings with a wide shank sit more tightly on a finger than thin ones. Therefore, their circumference should be slightly larger than that of their skinny counterparts. When you buy thin rings with a shank of up to 3 mm, there is no need to size up.

Option 2: Measure Your Finger:

This method has a high chance of error since any ring, unlike a thread or strip of paper, has a certain thickness. Rings of paper, thread, and metal are completely different things. A thread may get too deep into the skin while paper vice versa might be too loose.

  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 and narrow piece of paper rather than a thread is recommended. When you cut it to fit your finger, tape the ends together and make a paper ring. Then, try to put it on your finger so that it doesn’t get stuck on the joints between the phalanges. If you feel that such a makeshift ring hardly slights through your joints, you need to pick a ring one size larger.

​Although this method is simple, it is not 100% accurate. To minimise the percentage of error, doing it multiple times (around 5 times) and taking the mean value is recommended.
