Free ring sizer

Tungsten cannot be resized. It is far harder than gold or silver, which is what keeps it looking new for years, and also why a jeweller cannot stretch or cut it. So the first size matters, and we would rather help you get it right than swap it later.

Ask us for a sizer

We will send you a sizer at no cost, anywhere in the U.S. No purchase, and nothing to return. Request one here with your name and address and we will put it in the post.

Or measure at home right now

Two ways, both accurate enough if you take your time.

1. Measure a ring you already wear

Take a ring that fits the right finger and measure straight across the inside, edge to edge, in millimetres. That figure is the inside diameter, and it maps to a size in the chart on any product page under "Find your size".

2. Measure the finger

  1. Wrap a strip of paper or a piece of string around the base of the finger.
  2. Mark where it overlaps, then lay it flat and measure to the mark in millimetres. That is the circumference.
  3. Match the circumference to a size in the chart.

Getting it right

  • Measure at the end of the day, when fingers are at their largest.
  • Skip cold days. Fingers shrink, and you will size down too far.
  • The band has to clear the knuckle. If the knuckle is much wider than the base of the finger, go up half a size.
  • Wider bands sit tighter. On an 8mm band, consider going up half a size from what you measure on a narrow one.
  • If you land between two sizes, take the larger one.

If it still is not right

We offer one free size exchange per order on unworn rings within 30 days. Tungsten cannot be resized, so we send a new size rather than altering the ring you have. Details are in our refund policy, and there is more on wear and care in the FAQs.
