Know & Measure
Your Ring Size

There are several ways to check your size before you buy that perfect ring. The most accurate is to visit your nearest UK showroom where we can measure your finger exactly.

At Goldsmiths, we consider ourselves to be the experts when it comes to rings, and we recognise that obtaining the perfect fit is extremely important. With that in mind, we will work with you to ensure you know how to measure ring size to find the perfect fit.

You can print this off and use it to quickly work out your own, or your partner’s, ring size in mm. The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go up one size.
