Ring Sizing
Your engagement ring or wedding band should fit comfortably — not too tight, but not too loose either. The perfect ring fits loose enough to slide over your knuckle and tight enough so that it cannot fall off your finger.
To find your ring size, you can use James Allen’s online ring sizer or request a free plastic ring sizer. Keep reading for tips on how to measure your finger size and make sure that you purchase a ring that fits just right.

Online Ring Sizing
*Some rings cannot be resized and will need to be remanufactured. There will be a fee for rings that need to be remanufactured outside the 30-day return policy.

Tips for Finding Your Ring Size
Measure your finger at the end of the day.
Your finger size changes depending on the weather and time of day. For best results, measure your finger size at the end of the day when your fingers are warm. (Early in the morning, your fingers are cold and therefore smaller.)
Measure a few times. Be sure to measure your finger size a few times to make sure your calculations are accurate.

Tips for Buying a Ring as a Surprise
If you don't know your girlfriend's (or boyfriend's) ring size, ask her/his close friends or family members. Tell them to keep it hush-hush so that they don't accidentally ruin the surprise!
Borrow his/her ring (from the correct finger!) and use James Allen's online or plastic ring sizer to determine the ring's size.
Remember, you can have a James Allen resize your ring once for free within the first year of your purchase, including free return shipping within the U.S. and Canada for the first resize. For more information regarding ring sizing, feel free to contact customer service, which is available 7 days a week.
