The best way to check your ring size is to be measured by a jeweller. Alternatively, you can use one of the following methods to estimate your ring size:
Method 1: Using an existing ring that fits on your finger, measure the inside diameter of the ring. Then check the diameter to ring sizing in the chart guide below.
Method 2: Take a piece of string or a thin strip of paper (no wider than 0.5cm) and wrap it around your the base of your finger. Ensure that it is neither too loose or to tight, and that it can fit over your finger knuckle joint. Mark where the string/paper meets. Measure the string/ paper to get your ring circumference. Check the circumference to ring size in the chart.
Always recheck a few times.
Note that your finger swells and reduces throughout the day and during different seasons.
Use the guidelines above and this ring size chart to estimate your ring size. Please note this is a guide only.
