Ring Sizing

If you are unsure of your ring size, the best option is to visit a local jewellery shop near you and ask to have your finger measured. All jewellers can offer this service free of change. However if this is not possible you can measure your finger yourself using our guide below.

How To Measure Your Finger

   1. Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch).
   2. Wrap it around the base of the appropriate finger.
   3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
   4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
   5. Use this measurement and the chart to the right to determine your ring size.
   6. For the most accurate reading, measure the finger at the end of the day when the finger is the largest. 

Tips for Measuring Your Ring Size

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

Don't measure cold fingers. This is when fingers are their smallest.

For the most accurate reading, measure the finger at the end of the day when the finger is the largest.
