Visit Expressions Des Bijoux for a wide selection of exclusive designer rings. Find out how to measure a finger to make sure you order the correct ring size by follow these basic instructions.

Take a piece of string or a strip of paper that is no wider than 1.4 cm or half an inch. Simply wrap it round the base of the appropriate finger, and mark with a pen the point at which it overlaps to form a complete circle. Then with a ruler measure the length from the starting point of the string/paper to the pen mark. Check this measurement against the chart below to find the correct ring size.

Does the style ring affect my ring size? Rings which have a deep band width will need to be slightly larger than your normal rings so consider this when checking your size.

For the most accurate reading, don't measure cold fingers which is when they are at their smallest. It’s best to measure the finger at the end of the day when the finger is at its largest.

After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.

Buying a ring as a gift? Ask your partner's mother or one of their friends if they know the finger size.

Borrow one of your partner's rings (from the correct finger) and slide it down a tapered candle. Then measure using the chart above.
