USING A RING SIZER TO MEASURE YOUR FINGER
RING SIZING FROM EXISTING RING
The easiest way of working out your ring size is to measure the diameter of a ring you already own:
- Measure the ring diameter in mm using a ruler.
- Using the measurement, check the letter sizing chart above.
REMEMBER: It may be obvious but your fingers are all different sizes, make sure you measure a ring that fits the same finger you want to wear your new ring on.
MEASURING RING SIZE FROM SCRATCH
If you don’t have an existing ring to measure, or you want to wear your SAINT DAVIS ring on a new finger, you can use a piece of paper or string. Wrap the string round your finger and use a pen to mark where it meets. Then spread it flat and use a ruler to measure from the end to the mark you made. The length in mm can then be converted into a UK ring size using the chart above.
If you have any concerns about any of the above please contact info@saintdavis.com. We cannot accept returns due to rings being the wrong size. In the unfortunate event the size is wrong, we can resize the ring for a small fee.
