Ring Sizing Chart

Engagement rings are often given as a surprise during a marriage proposal, making it crucial to ensure the ring size is perfect. Rêve Diamonds offers a detailed ring sizing chart and practical tips to help you find the right fit.

Ring Size Chart - How to Measure Ring Size

Tips Before You Measure a Ring Finger

Always measure the finger at normal body temperature, as fingers can shrink or expand in different environments. If the knuckle is larger than the base of the finger, take two measurements and choose a size in between. This ensures the ring fits over the knuckle comfortably without being too loose.

How Do I Measure a Ring Finger?

To measure a ring finger, use a non-stretchy string or a strip of paper about 6 inches long and 1/4 inch wide. Wrap it around the finger, mark where it overlaps, and measure the length in millimetres. If the measurement falls between two sizes, choose the larger size. Remember, it's easier to resize a larger ring. For a deeper band, you may need a larger size.

If you prefer a professional tool, Rêve Diamonds can send you a Free Finger Sizer upon request, and we offer a complimentary ring resizing service.

Ring Size Chart

Check your ring size using our downloadable chart. Simply find a ring that your partner rarely wears and place it on the corresponding circles on the chart to determine the size. Ensure the grey line is visible inside the ring for accurate sizing.
