Ring Sizes

U.S. ring sizes follow a scale of numbers (and half numbers), typically from ring size 3 to 13.5 for adults. Women’s rings average between sizes 3-9, while men’s rings are usually between 8-14. Those units match up to your finger’s width in millimetres. So for example, ring size 3 fits a finger that is 14mm across, and the sizes climb from there.

What to Consider Before Buying a Ring

  • Consider your knuckle - if your knuckle is slightly larger than average, you might want to go for a ring that is half a size up from what you measure. This is so you can easily slide the ring to where you want it to sit.

  • Size accuracy - you don’t want to get this wrong, so measure your ring size a few times to make sure it’s accurate

  • Timing - consider when you measure your finger, because you fingers swell and shrink depending on the temperature and environment

How to Measure Your Ring Size

Option 1:

Use string or floss (or anything lying around that isn’t too stretchy)

  • Take a measuring tool and wrap it around the base of your finger and mark where the string or floss overlaps first

And then

  • Line the string up with the ruler and where you have market, should be your length in millimetres 

Option 2:

Place a ring you already have that fits the same finger and measure it on our Kimaï ring sizer app - it should match the circumference of your ring.

You can then use these measurements and take them with you to find your perfect fit!

Option 3:

Buy a simple ring sizer - they are reusable and inexpensive.
