Tom Jewelry Size Guide
SIZE GUIDE
Our size is standard US size. We suggest customers check your accurate US size at the local jewelry store. We also offer these suggestion methods to confirm your size.
Choose the comfortable ring you wear frequently, and use a ruler or a ring sizer tool to measure its inside diameter. Note the measurement in millimeters, then compare your inside diameter to our ring size chart to find your ring size.
Using a measuring tape or a piece of string, wrap it on your fingers tightly. Mark where the string or tape overlaps to form a complete circle. Then, match it to the circumference guide below to find your appropriate ring size.

Step 1 Cut a strip of paper or thin piece of string.
Step 2
Wrap the strip of paper or thin piece of string around your finger tightly.
Use a pen to mark where the paper or string meets.

Step 3: Lay the paper or string on a flat surface and measure the distance with a ruler.
Refer to the table below to find out your ring size.

Tips:
*Ideally, you should measure in the afternoon or evening when your fingers are at their most stable. To ensure accurate data, measure at least three times, as finger size can change throughout the day.
*Please also remember that the sizes of the right and left hands are different. Make sure to measure the finger on which you plan to wear your ring.
*A wider band means a tighter fit. If you're going bold, consider a bit of wiggle room.
*If your knuckle is larger than the base of your finger, measure both, then select a size between the two.
*If you hesitate between two sizes, always go with the larger one. If it is large, you can consider a ring size adjuster.
