TIP S F O R M E A SU R I N G R I NG SI Z E
MEASURING YOUR FINGER
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:
1. At the end of the day and when your fingers are warm (Fingers are smaller in the early
morning and when cold.)
2. Measure finger size 3 to 4 times to eliminate an erroneous reading.
Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an
inaccurate measurement.
A WORD ABOUT RING SIZES
Please be aware that ring sizes shown on Blue Nile reflect ring sizes used in the U.S. and Canada. To
find your ring size, measure your finger and then use the International Ring Size Chart to convert your
size to the corresponding U.S. size. That is the size you should order.
For example, a ring size H in Australia would be a U.S. size 4. To obtain the correct size ring, you would
order a U.S. size 4.
TIPS FOR BUYING THE RING AS A SURPRISE
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 the ring measurements
above to determine its size.
