Size (US SIZES)

FIND YOUR PERFECT FIT

Sizing shouldn’t be a guessing game. Whether it’s a ring, chain, or cuff — this guide will help you get it right the first time. And if it’s not quite perfect? You’re covered by our Perfect Fit Guarantee (scroll to the bottom).
FIND YOUR RING SIZE

Getting your ring size right matters — and while DIY methods can help, they come with a higher chance of error.

If you want to get the perfect fit, we recommend ordering our ring sizer kit or visiting a local jeweller for the most reliable result.

OPTION 1: DIY METHODS
USE A RING YOU ALREADY OWN

[40-50% chance of perfect fit]

Grab a ring that fits the desired finger. Measure its inner diameter in MM and match it to our size chart — this is the most accurate DIY method. If you can, use a calliper for an accurate measurement.

TIPS FOR ACCURACY

  • Measure at the end of the day (your fingers swell slightly). Don’t measure when your hands are cold (they shrink).
  • Consider the knuckle—if it’s larger than the base, measure both and choose a size in between.
  • If between sizes, size up for thicker bands or down for thinner ones.
  • Match the ring with the finger you want to wear it on. Remember that fingers vary in size, as does your left and right hand.
PRINTABLE RING SIZER

[30-40% chance of perfect fit]

Download our printable sizer or use a strip of paper around your finger, mark the overlap, then measure the length in mm.

TIPS FOR ACCURACY

  • Be sure not to pull too tight.
  • Ensure the page is set to 100% scale
STRING OR FLOSS METHOD

[30-40% chance of perfect fit]

Wrap a piece of string around the base of your finger, mark the overlap, then lay it flat to measure. This method can be less accurate — avoid stretchy materials.

TIPS FOR ACCURACY

  • String can stretch.
  • Tight wrapping can lead to incorrect sizing.
  • Try 2–3 times for consistency.
OPTION 2: RING SIZER KIT

OPTION 3: FIND A LOCAL JEWELLER

[90% chance of perfect fit]

For complete peace of mind, you can also pop into any local jeweller for a quick sizing — they’ll measure you in seconds.

This is a great option if it's a gift. Just bring a ring that the recipient already owns/wears and ask the jeweller to give you a size measurement.
