Method 1: Measure a ring that already fits
If you already own a ring that fits well, this is usually the easiest and most accurate option.
-
Place the ring on a ruler.
-
Measure the inside diameter (inner edge to inner edge) in mm.
-
Use the conversion table below to find your size.
Tip: Measure twice (top-to-bottom and left-to-right). If the ring is slightly oval, use the average.
Method 2: Measure your finger (no ring needed)
-
Cut a thin strip of paper (or use a non-stretch string).
-
Wrap it around the base of your finger (snug, not tight).
-
Mark where the ends meet.
-
Lay it flat and measure the length in mm - that’s your inner circumference.
Tips for best accuracy
-
Measure in the evening (fingers can be slightly larger).
-
Avoid measuring when your hands are very cold or very warm.
-
If you’re between sizes: size up (especially for wider bands).

Best practice: Use your mm measurement as the source of truth. Conversions can vary slightly by brand and ring width.
