How to Measure Ring Size Accurately with Our US Ring Size Chart
Are you looking for a stylish and durable Tungsten rings or titanium ring but unsure about your US ring size? Knowing your correct size makes all the difference, especially with materials like tungsten that can’t be resized. With the right ring size chart and a few simple tools, you can find a comfortable and accurate fit at home.

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. That consistency makes it easier to shop confidently, whether you're purchasing a tungsten ring or any other type of jewelry.
How to Measure Ring Size
There are two main ways to figure out your ring size:
-
Measure an existing ring: If you already own a ring that fits the same finger, you can measure its diameter or inner circumference using a ruler.
-
Measure your finger: Wrap a strip of paper, floss, or string snugly around the base of your finger. Mark the point where it overlaps, then measure the distance between the marks with a ruler to get the circumference.
Why Slight Variations Might Occur
While most jewelers follow the same US sizing chart, there can be slight differences—often just a half-size. These can happen due to how the finger is measured or minor rounding variations in tools.
Ring Size Chart & Conversion Guide
Finding the right fit matters for comfort and style. A ring measurement chart helps match your diameter or circumference to the correct US ring size and provides international conversions if needed. Whether you’re buying a wedding band, engagement ring, or fashion piece, a proper fit ensures it feels good all day.

Tips for Finding the Perfect Fit
Finger size can change slightly depending on time of day or temperature. Always measure at room temperature and avoid times when your fingers are swollen or cold. If the band is wider than average, consider going up half a size to maintain comfort.
Shop with Confidence for Tungsten Rings:
Using a ring size chart and the right measuring method helps you find the perfect fit. A well-sized tungsten ring means long-lasting comfort and style—exactly what you want from a ring that’s made to last.
