Between sizes? Always go up — fingers tend to swell slightly throughout the day, especially in warmer weather.
Cut a strip of paper
Around 10 cm long, no wider than 1 cm. Avoid stretchy materials.
Wrap around your finger
Wrap at the base of the finger you'll wear the ring on. Mark where it meets.
Measure the length
Lay flat and measure from end to mark in millimetres — this is your circumference.
Match to the chart
Find your number in the mm column. If between two sizes, choose the larger.
Measure at the end of the day. Cold fingers can read up to half a size smaller than warm ones.
