Not sure of the size? Don’t let it hold up your design call. We can design the ring first and confirm the size before it’s made.
Measure a ring that already fits
- Choose a ring worn on the same finger. Hands differ, so left and right can be a size apart.
- Lay it on a ruler and measure the inside diameter, edge to inside edge, in millimetres.
- Find the closest diameter in the chart below. If it falls between two sizes, choose the larger.
Measure your finger
- Cut a thin strip of paper about 10 cm long.
- Wrap it around the base of the finger, snug but able to slide over the knuckle, and mark where it overlaps.
- Lay it flat and measure to the mark in millimetres. That’s the circumference. Find the closest one in the chart.
- Measure at the end of the day, when fingers are largest, and not when your hands are cold.

Wide bands (6 mm and up) fit more snugly, so go up half a size. On your design call we’ll talk through the fit, and we can post you a free ring sizer to be sure.
Planning a surprise? We can make the ring in a likely size and resize it afterwards, where the design allows.
