Ring Sizing Chart for US Sizes


All jewelers across the US, Canada, and many parts of Mexico use standard US ring sizes when measuring and producing their rings. For those who are not sure of their US ring size, they can figure it out by finding out the diameter or circumference of either a ring they currently wear or by measuring their finger. Do not use the ring sizers that you print out on-line.  Most of the time your printer will not print it out in the correct size, so when they are used customers often get an incorrect size.

All jewelers use basically the same chart, with minor differences due to rounding. Sometimes a finger could get measured at one size by one jeweler and then another jeweler the same finger is measured a half size different from the first jeweler. This is due to the fact that there may be variances in the measurements of the sizes jewelers use.

Our measurements are given below for each size and we also offer a free ring sizer. If time permits, simply fill out the request form on the right and we will send you a sizer for free. Depending on where you are in the US, it could take about 2 - 5 days for the sizer to arrive in your mail. For international customers, it could take 1 to 2 weeks because it has to go through customs.
