Temperature causes an inaccurate reading while measuring your ring size. Your fingers will be at least half a size smaller when your hand is too cold while it will be half a size bigger when it is too hot. Measure your finger in average temperatures, preferably at the end of the day when your fingers are at their largest.

The wider band a ring has, the tighter you will feel. So, if you wish to order a band approximately 6 mm wide or more , move up a size from the normal ring size worn. Also, the rings with large stones may cause the band to lift up when laid on its side. Keep in mind that you should order the next size up since it slightly distorts the size.

If your knuckle is larger than the base of your finger, measure both your knuckle and the base of your finger and select the size in between two.

Your ring should fit enough not to fall off and loose enough to slide over your knuckle. If you hesitate between two sizes, always go with the larger one.

Repeat measurement 2 to 3 times to eliminate an erroneous result.
