Have you found a ring you like but don't know your size? Or are you planning to propose to your partner and need the right ring size? There are various ways to measure your ring size or your partner's. We explain the options below to determine your ring size.
Option 1: Measure your existing ring
Do you already have a ring that fits well? This is the easiest way to measure your ring size. Follow the steps below to measure the diameter of your ring.
- Choose a ring that fits well on your finger.
- Measure the inside diameter of the ring in mm.
- Look up the diameter and corresponding size in the ring size chart below.
Option 2: Measure your finger
Another method to determine your ring size is by measuring the circumference of your finger.
- Take a measuring tape, string, or strip of paper.
- Wrap it around the finger where you want to wear the ring and mark the point where it meets.
- If you used a string or strip of paper, lay it flat and use a ruler to measure the circumference in mm.
- Look up the circumference and corresponding size in the ring size chart below.

What about different ring sizes?
Since you can calculate your ring size in different ways, there are also various sizes that can indicate your ring size. The notation also varies by continent or country. In The Netherlands, we usually use the diameter, which for example corresponds to ring sizes 16, 17, 18, or 19.
You can also look at the circumference. A circumference of 52 mm corresponds to ring size 16.5. Ring size 17 equals size 53, and ring size 18 converts to size 57.
What is the average ring size for a woman?
Just like with clothing, ring sizes vary per person. The average ring size for a woman in The Netherlands is around size 17. This obviously varies per finger. Your ring size can even differ per hand. Your dominant hand is often more developed, and these fingers might be slightly bigger than the ones on your other hand. For instance, if you are right-handed, your right ring finger may be larger than your left ring finger. This is not the case for everyone but is good to keep in mind before purchasing a ring.
