Sizing Chart

Wrap a strip of paper around the base of your finger. Don’t wrap it too tightly or too loosely—just make sure it fits snugly. Aim for a piece of paper about 0.5 to 1 cm wide.
Carefully mark where the ends meet, then unfurl the paper.
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.
