Ring Size Chart

Rings Size Guide

The size of each ring is determined by the diameter/circumference of the inner band of the ring. It is measured in mm, cm or inches, with each country having a different system of letters and numbers. US size standards are usually followed, which are most often identified by the numbers 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5 and etc. At Prestige Carat, rings are sized specifically to the US standard and the European standard in parentheses next to them.

How To Measure Your Ring Size

  • Ring Size Measurement

    Method 1: Measure a Ring

    1. Find a ring that fits comfortably on the finger you intend to wear your new ring on.
    2. Measure the internal diameter of the ring, using a ruler or measuring tape. To do so, ensure you are using a ruler with millimetre (mm) measurements, then place your ring on top of the ruler and measure the inside of the circle – in other words, the part that is in contact with your finger.
    3. Use our Ring Size Chart to convert your diameter measurement into the correct ring size.

    Method 2: Measure your Finger

    1. Cut a piece of string or paper to a length of around 10 centimetres (cm).
    2. Wrap the paper or string around your finger at the point where the ring should sit. Pull so that the string fits comfortably around your finger - not too tight and not too loose.
    3. Use a pen to mark the point where the end of the string or paper overlaps itself.
    4. Lay the string or paper out against a ruler or tape measure, and measure the length (mm) from its end to the point you have marked with pen.

    Expert Tips

    1. Always double-check your measurements for accuracy.

    2. Your finger size can fluctuate slightly during the day, over time, and depending on the temperature. If measuring your actual finger, do so in the afternoon when your hands are warm for best results. If you fall between two ring sizes, choose the larger size (or half size) to ensure a comfortable fit.

    3. Ensure you measure the exact finger on which you intend to wear your ring (or a ring that you wear on the same finger). Your ring size will vary between your fingers as well as between your hands.
