HELPFUL TIPS

Helpful ring sizing tips

When you’re finding out your ring size, don’t forget these useful tips.

1

Avoid measuring for a ring when your fingers are cold as you will be half a size smaller.

2

The evening is the best time to measure your finger, as this is when they are at their largest.

3

Measure your finger at least 3 times to make sure the ring size is correct.

4

Wider Rings will fit a bit tighter, so you will need to go up a size.
