How To Find Your Perfect Ring Size

There are several reliable methods to determine your ideal ring size. If you already have a ring that fits perfectly, you can either measure it directly or compare it to our size table. If you don't have a ring to reference, you can measure your finger directly to find your size. Discover our simple sizing methods below to ensure your new ring sits perfectly on your finger.

 

 

Method 1: Measure an Existing Ring

1. Find a ring that fits well on your intended finger
2. Place the ring on a ruler with millimeter (mm) markings and measure the internal diameter (the part that touches your finger)
3. Match your measurement to our Ring Size Chart to find your exact size

 

 

Method 2: Measure Your Finger

1. Cut a 10cm strip of string or paper
2. Wrap it around your finger where the ring will sit - snug but not tight
3. Mark where the strip overlaps with a pen
4. Lay the strip flat and measure the length to your mark in millimeters
5. Use our Ring Size Chart to convert this circumference to your ring size

 

 

For best accuracy, measure in the evening when your finger is at its largest. Need help with conversion? Just ask!
