How to Measure Ring Size: Guide for US Sizes

Are you looking for a stylish and durable Tungsten rings or titanium ring but unsure about your US ring size? Don't worry, this guide will help you find the perfect fit!

How To Measure Ring Size

Standardized Sizing for Rings:

The good news is that most jewelry stores in the US, Canada, and parts of Mexico use the standard US ring size system for rings and other jewelry. This makes it easier to find the right size, no matter where you shop.

How to Measure Ring Size:

There are two main ways to determine your US ring size for rings:

  • Measure an existing ring: If you have a ring that fits you comfortably on the finger you plan to wear the tungsten ring, you can measure its diameter or inner circumference using a ruler. 
  • Measure your finger: Wrap a strip of paper, floss, or piece of string snugly around the base of your finger and mark the spot where it completes the circle. Then, measure the distance between the marks using a ruler.

Why Slight Variations Might Occur:

While most jewelers use the same basic US ring size chart, slight variations can sometimes lead to a half-size difference in measurements. This can be due to minor rounding differences or even how the jeweler measures your finger.
