Finding Your Ring Size

As your finger measurement will vary depending on time of day, measure your finger in warm temperatures or when your finger is at its largest.

If you knuckle is a lot larger than the base of your finger, when using method make sure you measure both the knuckle and the base of finger and select a ring in the middle of both sizes.

If You’re Buying the Ring as a Surprise

Ask your intended recipient’s mother or friend if they know his/her ring finger size.

Borrow one of your intended recipient’s rings and use METHOD A below. (make sure to borrow a ring that fits the finger you intend your gift ring to fit).

Other Tips

When considering a wide band, move up a size from your measurement, for comfort’s sake.

Different countries have different ring-size systems. All sizes listed here are standard UK sizes. If you know your ring size in another system this is not a problem as you can use the chart below to convert.

Method A

Measure a ring that fits you or your intended recipient. Measure the inside diameter of the ring in millimetres.  If you are between sizes, order the larger size.

Method B

Find a piece of non-stretchy string or strip of paper no wider than 1cm.

Wrap it snugly but not tight around the base of your finger.

Using a pen, mark the point on the string or paper where it overlaps, forming a complete circle.

Measure the length of string up to where you marked the string/paper in millimetres. Contact me with this measurement and I can let you know what size you need.
