RING SIZE GUIDE

We encourage every customer to be sure of their size before making a purchase, either by measuring with a ring sizing tool or going to a local jeweller.

The best time for measuring your finger size is at the end of the day when your hands are warm.

If you are looking to buy a wide ring, we recommend you to move up one or two sizes.

The average ring size for women is approximately M in the UK, while the average size for men is approximately size U.

When buying from How Fine Designs please use the UK size chart.
