Size Guide
Finding the right ring size at home takes about two minutes. Getting it right matters – the ring should feel secure but never tight.
Ring sizes
RYMONA Ring is available in sizes 6 to 13 (US sizing). Check-out lists every size in stock.
Measuring at home
Use a strip of paper or a piece of string with no stretch.
- Wrap it around the base of the finger you intend to wear the ring on – the widest part, usually over the knuckle.
- Pull it snug, but not tight, and mark where it overlaps.
- Measure the marked length in millimetres: that is your finger circumference.
- Match it to the chart below. If you are between two sizes, choose the larger one.
Finger circumference: size 6 = 52 mm · 7 = 54 mm · 8 = 57 mm · 9 = 59 mm · 10 = 62 mm · 11 = 65 mm · 12 = 68 mm · 13 = 70 mm
A few tips
- Measure at the end of the day, when your fingers are at their largest.
- Cold hands read small – warm your hands first.
- The ring should slide on with slight resistance and sit comfortably. If you can shake it off easily, it is too loose.
- Wear it on your index or middle finger for the most accurate sensor readings.
