Ring Sizing

For accuracy, we recommend visiting us (or another jeweller) to be properly measured. If you are unable to do this, you can measure a ring you already own or use some string (see beneath the chart).

The string method

First, find some string or some paper (no wider than 1.4 cm) and wrap it around your finger. Use a pen to mark where the string or the paper overlaps (forms a circle). Then, measure the string or paper against a ruler from the starting end to the pen mark. Use the chart above to determine your UK ring size.

How should the ring fit?

The ring should feel comfortable - it should slide over your knuckle with a bit of friction, but not be too tight. There might be more resistance to take it off. If it's leaving indent marks, it's too tight and will need sizing up. If it feels like it will fall off easily, it's too big and will need sizing down.

Measuring a ring you already own

You can either measure the diameter opening of the ring. Or, if it’s easier, draw a circle of the inside of the ring and measure the diameter then.

When should I measure my ring size?

The best time to measure your ring size is when your hands are warm: so in the afternoon or evenings. Our fingers naturally fluctuate in size during the day. In the evening, our fingers are at their largest and by measuring later in the day, we are better able to ensure a comfortable size. It’s also worth measuring your finger size several times to make sure that the measurement is as true to size as possible.

Things to note

  • For thinner rings, you may need to go down a size. Likewise, rings with a thicker band may feel tighter and you may need to go up a size.

  • It may sound obvious, but each finger is a different size - and the fingers on one hand will be bigger than the other. You will likely find that your dominant hand will be bigger than the other.

  • If in doubt, size up. It’s easier for us (and less expensive for you) to resize the ring down.
