Ring Guide Chart
1.Measure your ring size with a finger strip chart
Attention! Please noted that you should ensure your hand size before you order the rings. If you are not sure of your hand size, you can use our "finger size” guide chart. If you are helping your friends buying, you only have to tell him or her
using a measuring tape to measure the length of finger according to step 1 & 2. then you can use the "Ring Size Table " to compare with the relevant size matching the length. If you can’t find the same size of the matching length, the size of the order you usually make will increase, so the rings wouldn’t be too small when you wear them.
Step 1: Cut a straight piece of paper, the size is approximately 3 inches (length) *1/2 inches (width).
Step 2: Use a piece of paper to cover around your finger, and make the mark on the end of the paper.
Step 3: Draw X mark on the finger size guide chart, then print it out, stretch this note, mark "X" on the terminal of this note, this is just the right finger size. Please click there to use a US Letter print a ruler.

2.Determine your ring size with an existing ring
Use a ring that fits you to determine your ring size. Place your ring over the nearest size circle. The inner edge of the ring should align with the outer edge of the circle. If your ring appears to fit between two sizes, buy the larger size.
