what size ring do i wear
The easiest way to find your ring size is to measure the inside circumference of a finger with a strip of paper or string, then match it to a ring-size chart. A good fit should slide over your knuckle and feel snug without pinching.
How to measure at home
- Wrap a strip of paper or non-stretch string around the finger you’ll wear the ring on.
- Mark where it overlaps.
- Measure that length in millimeters with a ruler.
- Compare it with a sizing chart.

Helpful tips
- Measure at the end of the day, when fingers are usually a bit larger.
- If you’re between sizes, choose the larger one.
- Wide bands can feel tighter, so you may need to go up by half a size.
