Browsers usually render in sync with the monitor's refresh rate, so the measured FPS is close to the refresh rate. Heavy background activity can lower the reading.

How to use

  1. 1

    Open the page and it measures FPS automatically.

  2. 2

    The estimated refresh rate (e.g. ~144Hz) appears.

  3. 3

    Check the resolution, pixel ratio, and other screen info too.

Yes — it is completely free to use, with no account or sign-up required.

What is this tool?

Measures your screen's frames per second (FPS) in real time with requestAnimationFrame to estimate the monitor's refresh rate. Browsers usually render in sync with the refresh rate, so the reading lands close to real values like 60, 120, 144, or 165Hz. It also shows your screen resolution, browser viewport size, pixel ratio (DPR), and color depth. Everything is measured in your browser, free with no install.
