Find the perfect fit
Whether you are looking to treat yourself or surprise a special someone, we are yours for the asking with ring sizing tips.
Where would you like to start?
A note on fit & feel
Between two sizes? We'd suggest going with the larger one.
Fingers change subtly with the season and time of day. Measure toward the end of the day, when they feel at their most natural.
A wider band fits more snugly than a fine one. We recommend sizing up.
Planning to stack? Size up for a more comfortable fit. Discover stackable rings.
Measure a ring you already wear
The most reliable starting point
- 01Choose a ring that fits the finger you'll wear your new piece on. The fit should feel natural — not too loose, not too tight.
- 02Lay it flat and measure the inside diameter — from one inner edge directly across to the other, in millimetres.
- 03Enter your measurement below to find your Wouters & Hendrix size instantly.

Measure your finger
Using our printable ring sizer
- 01Download and print our ring sizer. Make sure to print at 100% scale — check the 2 cm reference line on the page before cutting.
- 02Cut out the ring sizer and wrap it around the base of your finger, where your ring will sit. If your knuckle is noticeably wider, take a reading midway between the base and the knuckle.
- 03Your size is indicated where the arrows meet. If you fall between two sizes, choose the larger one.
