Sizing Chart

Wrap a strip of paper around your finger, just above the knuckle. Don’t do this too tightly, make sure the paper feels comfortable. You can also measure the base of the finger too, to make doubly sure that the ring will fit. Aim for a piece of paper that’s about 1 cm wide.
Carefully mark where the ends meet, then unfurl the paper – or if you’ve used our ring sizer, read the value on the sizer that the arrow points to, where the paper is pulled tight.
Measure from mark to mark on the paper to find your circumference (mm) or take the value you already have and check your size on the chart bellow.

REMEMBER: You can also use string for this measurement, but as string can be stretchy, we find paper more reliable.
