Finding your size has never been easier with the Dylan Oaks ring size guide. The easiest way of working out your own ring size is to measure the diameter of a ring you already own:
Step 1
Lay the ring on top of a ruler, and measure the widest area inside the ring from the inner edge to the inner edge. Round off to the closest whole millimeter.
Step 2
Using the measurement, check the letter sizing with the sizing chart below:

Tip: If your ring is a different shape than a circle, measure the shortest distance across it.
REMEMBER: It sounds obvious but your fingers are all different sizes, so make sure you measure a ring that definitely fits the same finger you want to wear your new ring on.
