Ring Size Chart

Size Charts Are Our Obsession. And Rings Are No Exception.

At Size Chart HQ, we believe the perfect fit is essential, even for something as small as a ring. That’s why we’ve crafted a comprehensive Ring Size Chart, providing you with everything you need to find your ideal size. Say goodbye to the guesswork and frustration of ill-fitting rings, and hello to the confidence of knowing your jewelry will feel as good as it looks. Because when your ring fits perfectly, it’s not just an accessory, it’s an extension of you.

Instructions: Wrap a string comfortably around the base of your finger. Mark the string where it overlaps, then measure the length of the string up to the mark. That’s your finger’s circumference!

Frequently Asked Questions

It’s easier than you might think! Here’s a quick guide:

  1. Grab a string or a thin strip of paper.
  2. Wrap it snugly around the base of your finger where you’d like the ring to sit. Make sure it’s comfortable and can slide over your knuckle.
  3. Mark the point where the string or paper overlaps.
  4. Measure the length of the string or paper up to the mark. This is your finger’s circumference.
  5. Use our Ring Size Chart to find your corresponding ring size.

 

Remember:

  • It’s best to measure your finger at the end of the day when it’s slightly larger.
  • If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between.
  • If you’re between sizes, it’s usually better to size up slightly for comfort.
