Ring Sizing

The best way to find your correct ring size is to visit one of our shops and have your finger measured using a wedding band gauge.

'Wheatsheaf' is the commonly known gauge for measuring finger size in the UK, and this is the system we use at Sheila Fleet Jewellery. We can also accommodate European millimetre dimensions and measurements from the USA and Canada, and we have a special ring stick in our workshop that can size rings to this specification.

See the chart below for a list of sizes as a guide. This conversion chart is simply a guide and sizes do not exactly cross over - we recommend you visit one of our shops or concessions to ensure you have an accurate sizing done.

British sizes

Here we show a ring being measured to the leading edge on a wheatsheaf ring stick.  As you can see the letter O is slightly covered.

Ring Width and Finger Measurement

Always consider when ordering your ring the actual width of the ring. On narrower rings you can use a 4mm gauge and you will see on this image the finger size is K. This is ideal for rings measuring up to 5 - 6mm wide.

This image shows a wedding band gauge showing a size L. This would be ideal if it was for a wider ring.

Example - normal finger size K

Ring width

4-5mm  size K

6 - 7 mm size K ½

7mm - 10mm size L.

Please note, these measurements are for guidance only, as all people have different knuckle sizes and their own preference on how loose or tight they wish to wear rings on their fingers.

D-section rings

Ogham ring R99 and Runic ring R34

These rings are rounded on the inside so half a size smaller must be ordered to ensure a good, comfortable fit.
