Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle.
Finger size changes depending on the time of day and the weather. For best results measure your finger size:
Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement.
Ask your significant other’s friends or mother if they know her finger size.
Borrow one of your significant other’s rings (from the correct finger) and use our downloadable guide below to determine its size.
Print out this easy to use guide and place the ring over the circles, matching the inside edge of the ring to the circle nearest in size. If the ring falls between 2 sizes, order the largest.
