Tips for getting it right
Measure at the end of the day
Fingers tend to swell throughout the day. Measuring in the late afternoon is the most accurate.
Pay attention to temperature
Cold contracts fingers. Measure with warm hands for a more accurate result.
Repeat the measurement
Measure two or three times to confirm. A single measurement may not be enough.
Between two sizes
If in doubt between two sizes, always opt for the larger one for greater comfort.
Each finger is different
Sizes vary between fingers and hands. Always measure the specific finger.
The ideal fit
The ring should slide smoothly and fit without pinching. It should not come off on its own.
