Titanium design band ring.

How to measure your ring size:

You can use a string or paper, just make sure if using a string it does not stretch. Cut a piece of paper 6" long and 1/4" wide. Wrap the paper around the base of your finger so it fits snug but not too tight. Mark the point on the paper where it overlaps forming a circle. Measure the length from the starting point to the mark on the paper. If the measurement falls between two sizes, go for the larger size. Use the chart pictured in the listing to find your size. Measurements using millimeters will be the most accurate, and you can easily convert a measurement in inches to millimeters online. 

Tips for finding a perfect fit:

Measure your finger in a warm temperature at the end of the day, the finger will be at its largest during this time. The ring should fit snugly on your finger and slide smoothly when you put it on, but not come off easily. Be sure to check your size several times to get the right fit. Consider the width of the band, wide rings require a larger size for most people, so you should consider going up a half size. Typically one hand is larger than the other (usually your dominate hand); to avoid any errors be sure to measure the finger you plan wearing the ring on. Measure both the base of your finger and your knuckle and select a size in between the two. This will allow you to slide the ring over your knuckle, but it won't be too large to be comfortably worn on the base of your finger. If two sizes seem to fit or if you get two different finger measurements, go with the bigger measurement or consult a professional.
