How to Measure Your Mens Ring Size at Home:

  1. Get a Ring that Fits: Find a ring you currently own that fits the finger you intend to wear the new ring on. Ensure it's a similar style to the one you plan to purchase (wide bands may require a slightly larger size).
  2. Measure the Inside Diameter: Use a ruler or callipers to measure the inside diameter of the ring from one edge to the other, across the widest part.
  3. Use the Chart: Compare the inside diameter measurement in millimetres to the chart above to determine your ring size.
  4. Check for Comfort: Make sure the chosen size feels comfortable on your finger. It should slide on easily but not be too loose. If you're between sizes, it's generally a good idea to go for the larger size for comfort.
  5. Consider the Time of Day: Fingers can swell slightly during hot weather or in the evening, so measure your ring size at different times if you're unsure.
  6. Consult a Jeweller: If you have any doubts about your ring size, visit a local jeweller for a professional mens ring sizing. They have tools to measure accurately.

Remember that mens ring size may vary slightly between different brands and styles, so it's a good idea to check if there is any information on sizing that is specific to the ring you have chosen to confirm the fit of a specific ring before purchasing. Additionally, international sizing systems may have slight differences, so double-check the sizing conventions in your region and use the millimetre (mm) measurements as the guide to find the conversion to or from your local ring size.

All of our mens rings are US ring sizes unless stated otherwise.
