Size Guide


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:

Size Guide Rings

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:

Dylan Oaks International Ring Size Chart
Inner Diameter Sizes
(mm) UK US EU
16.3 L 6 51
17.1 N 6.5 53.5
17.7 P 7.5 56


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.
