 All DOUBLETAKE rings come in standard US sizes. If you're between sizes we would typically suggest sizing up. Not sure about your ring size? Don't worry there are a couple easy ways to figure it out below.


  • Your fingers are smaller when they are cold so make sure your hands are slightly warm when measuring your ring size
  • If you fall between sizes it's normally better to size up instead of sizing down

There are a few different ways you can work out your ring size:

1. Measure the diameter of a ring you own
If you have already own a ring that fits on your finger, you can simply measure the inside diameter of the ring. You do this by taking a ruler and measuring straight across the middle of the ring.
