Ring Size Guide
Find your perfect fit with the Paris Jewellers Size Guide. Use our measurement charts and simple tips to choose the right size for you or someone special.
Measure Your Finger
- Get a string or flexible tape.
- Wrap it around the finger you intend to wear the ring on. Make sure it is snug around your finger so that it’s comfortable and not too tight.
- If using a string, mark the point where the ends meet.
- Lay it on a flat surface and measure the marked section with a ruler.
- Compare your results with the sizing chart on this page.
Measure an Existing Ring
- Take a ring that fits comfortably on the finger.
- Measure the interior diameter of the ring in millimeters (mm) and compare to the sizing chart on this page.
- Alternatively, print our ring sizer, and place your ring on top of the circles in the chart. Make sure the inside of the ring lines up with the outside edge of the circle.
