Helpful ring sizing tips

When you’re measuring ring size, don’t forget these useful tips.

1

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

2

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

3

Measure your finger at least 3 times to ensure the correct size reading.

4

Rings with wider bands will fit a bit tighter, so you may need to go up a size.
