Ring Sizing Guide

Top 5 tips to measure your ring size:

  1. When using a sizer, pull tightly. The sizer must fit comfortably yet snugly to produce an accurate size.
  2. Measure your finger at the time of the day when it will be at its largest — usually at the end of the day. Please keep in mind, your ring size can fluctuate about a half size based on your temperature, hydration levels, and hormones.

  3. Avoid measuring your fingers when they are cold or damp.

  4. Bands and rings over 5 mm in width may fit your finger more tightly than rings of the same size in narrower widths.

  5. The most accurate way to determine your ring size is by visiting a local jeweler or Caratice showroom. Book an appointment with our diamond experts for personalized guidance.

Find someone else’s ring size:

The best method is to measure a ring they wear on their ring fingers, although the left and right ring fingers may vary slightly in size. If they only wear rings on other fingers, you can still measure it to get close to their true size and anticipate resizing after you propose (excluding Infinity and Eternity Bands). If you’re unable to measure a ring, ask a close friend or family member who might know their size.
