A Ring Size Guide for Surprise Gifts

The safest way to estimate ring size is to borrow a ring the person already wears on the same finger and measure the inside diameter. If that is not possible, ask someone close to them or choose an adjustable/open design.

Measure at the end of the day if the recipient is measuring directly. Fingers shift with temperature and time, so a comfortable size is better than a tight one.

When in doubt

For surprise gifts, adjustable rings and open cuffs reduce risk. The gesture stays intact, and the fit is more forgiving.
