Before you decide

Measure at the end of the day. Fingers are largest in the evening and when you're warm. Morning sizes run small.

Check over the knuckle. The ring has to pass the knuckle to sit at the base. If your knuckle is larger than the base of your finger, size for the knuckle.

Between two sizes? Choose the larger. A ring that's slightly loose can be adjusted. One that won't pass the knuckle can't be worn.

Wide bands fit tighter. For the Dual Rail Eternity Band, consider a half size up.

Not sure? Try it on at home first.

The Ring Try-On Kit includes a ring sizer, and 10 ring shapes at true size.
The full price comes off your ring, for 365 days.

Got it wrong?

It happens. Most rings can be resized within one or two sizes. Write to hello@henryfrancis.com and we’ll arrange it.

The Solitaire's resizing is limited and the Eternity Band can't be resized. To be certain of your size first, use the ring sizer in our Ring Try-On Kit.
