Ring Sizing

📏 Not quite sure what your ring size is?

Different jewellery brands use different measuring tools, and what’s called a “US 7” somewhere else might not match mine. I use mm measurements to make sure your ring fits properly. I've put together a couple of easy ways to check your ring size at home to be sure!

Option 1: Paper strip method

  1. Cut a strip of paper (about 10cm long, 1cm wide)

  2. Wrap it around your finger where the ring will sit

  3. Mark where the ends meet (not too tight, not too loose)

  4. Lay it flat and measure the length in mm - this is your finger circumference

  5. Match your circumference to the size chart


Option 2: Use a ring you already own

  1. Grab a ring that fits the finger you want to size

  2. Place it flat on a ruler

  3. Take a clear, close up photo from directly above

  4. Measure the inner diameter in mm

  5. Match it to the chart

 Option 3: Send a Photo

  • Place your ring flat over a ruler

  • Take a clear photo (from straight above, not at an angle)

  • Make sure we can see the mm marks clearly

  • Send it to us and we’ll help figure out your size info@metalbonesjewellery.com

Important to Note:

  • Hands can swell in warm weather or at the end of the day

  • Your dominant hand is usually slightly bigger

  • Wide rings can feel tighter - sizing up half a size helps

  • It's normal to get slightly different measurements each time

  • When in doubt, it's safer to go up a size for comfort
