How to determine Your Ring Size

 

Using an existing ring

  • Make sure that the ring you measure fits the intended finger.

    Engagement and wedding rings are traditionally worn on the ring finger on the left hand in the United Kingdom

  • Place the ring over the circles below, matching the inside edge of the ring to the circle nearest in size. This measurement refers to the inside diameter of the ring.

  • If the ring falls between two sizes, order the larger size.

measurements match the inside edge of the ring

Tips for measuring ring size

Measuring your finger

Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle.

Finger size changes depending on the time of day and the weather. For best results measure your finger size:

  • At the end of the day and when your fingers are warm (Fingers are smaller in the early morning and when cold.)
  • Measure finger size 3 to 4 times to eliminate an erroneous reading.

Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement.

Tips for buying the ring as a surprise

Ask your significant other’s friends or mother if they know her finger size.

Borrow one of your significant other’s rings (from the correct finger) and use the ring measurements above to determine its size.

Free resizing

We provide free re-sizings on all rings if the desired difference is no greater than one ring size for a ring with a plain band and half a size for a ring that has diamonds in its band.

International size conversion

If ordering from outside of the UK, determine your ring size according to your country’s standard. Then use the International Ring Size Chart to convert to the corresponding UK ring size to place your order.
