Ring Size

Easily measure your ring size.

This tool from Xolotl Estudio helps you find your ring size using only your phone's screen. It's designed so you don't have to mess around with rulers or strings and get a clear reference instantly.

What can you do with this app?

Measure with a ring: Place a ring you already own on the screen and adjust the circle until it fits perfectly.

International sizes: Check measurements for US, Mexico, Europe, and other systems.

Screen adjustment: Includes a calibration option to ensure the millimeters you see on screen are real.

Save measurements: Keep a record of your sizes or someone else's so you don't forget them.

Why use it?

We made this because, in our jewelry workshop, we know that a single millimeter changes everything. It’s a simple tool made by someone who actually works with metal and rings every day.

Note: Don’t forget to follow the calibration steps when you open the app to make sure the measurement is as accurate as possible for your specific phone model.

Always have your ring size handy.
