Find your size in 60 seconds
Getting the size right is the difference between a ring you forget you're wearing and one you take off. Measure once, properly — here's how.
Size finder
Enter the measurement you took and we'll tell you your size.
No ring on hand
- Cut a strip of paper about 4 in long and ¼ in wide.
- Wrap it snugly around the finger you'll wear the ring on — snug, not tight.
- Mark where the paper overlaps with a pen.
- Unwrap it and measure to the mark with a ruler.
- That number is your circumference.
You already own a ring
- Pick a ring that fits the finger you'll use.
- Lay it flat on a ruler.
- Measure straight across the inside, edge to edge.
- That's your inner diameter.
Tip: measure at the end of the day, when fingers are at their largest.

Between two sizes? Go with the larger one. Fingers swell in heat, during exercise, and after salty meals — a slightly loose ring still reads your data accurately, a tight one gets uncomfortable fast.
