Tips for Accurate Measurements

To get the most accurate results from our actual size ring chart, follow these important tips:

Screen Calibration is Critical

Always calibrate your screen with the credit card reference before measuring. Different monitors and zoom levels can affect accuracy.

Measure at the Right Time

Finger size fluctuates throughout the day. Measure in the late afternoon or evening when fingers are at their largest.

Consider Ring Width

Wide bands (over 6mm) require a larger size than thin bands. Consider going up a half size for wide rings.

Account for Weather

Cold weather makes fingers smaller, hot weather makes them larger. Measure when your hands are at normal temperature.
