Ring Size Measuring Tool

While this tool is a useful guide, we highly recommend visiting a local Zales store for a more accurate measurement, as some rings are difficult to or cannot be resized.

Step 1 of 2

  • Place credit card on screen below and adjust with the + and - buttons until the sizes are equal.

When your credit card matches the image, click NEXT STEP.

Step 2 of 2

  • Using a ring that currently fits, place on the circle below. Use the + and - buttons to adjust the slider until the circle fits perfectly inside the ring. A ring that will lie flat against the screen works best.
  • If no ring is available, create one using a strip of paper and tape.
  • The estimated ring size will show inside the circle.
