FPS Test - Check Your Monitor's Real Frame Rate Online
Your monitor may support 60 Hz, 120 Hz, or even 240 Hz - but is your browser actually delivering that many frames? This free FPS Test measures your delivered frame rate in about 10 seconds and compares it with your selected refresh rate. It works in your browser, requires no download, and supports displays from 60 Hz to 360 Hz.

How the FPS Test Works
1. Select Your Refresh Rate
Choose your monitor's expected refresh rate from 60 Hz to 360 Hz before starting the test.
2. Run the Test
Click Run Test and keep this browser tab open for about 10 seconds while the tool tracks rendered frames.
3. Analyze Your Results
Review your average FPS, 1% low FPS, frame time, stutters, and consistency score to compare actual frame delivery with your selected refresh rate.
What Your Result Means
Your FPS Test result shows more than a single number. It tells you how closely your browser matches your monitor's refresh rate and whether your frames arrive at a steady pace. A smooth experience depends on frame pacing, not just a high FPS average.
During our test, a 120 Hz display averaged 118 FPS with an 8.44 ms frame time, 58 FPS 1% low, and only 2 stutters over 183 rendered frames. That is why the report marks the display as healthy; it is staying close to its expected refresh rate.
Use this guide to read your score:
- Under 30 FPS: Motion looks choppy and fast movement becomes hard to track.
- 30-47 FPS: Fine for slower games, but aiming feels heavy.
- 48-74 FPS: Smooth for most single-player games and everyday use.
- 75-119 FPS: Fast turns look clearer, and high-refresh displays become noticeable.
- 120-239 FPS: Competitive range with lower frame time and better tracking.
- 240+ FPS: Built for esports players, although gains become smaller for most people as refresh rates increase.
Why Your FPS May Be Lower Than Your Refresh Rate
A lower FPS doesn't always mean your monitor has a problem. In most cases, your browser, operating system, or hardware limits frame delivery before your display reaches its maximum refresh rate. Background apps, VSync, power-saving mode, high graphics settings, and CPU or GPU load can all affect performance. Even browser tabs running in the background can reduce rendering speed.
A small gap is normal. For example, a 120 Hz display reporting 118 FPS is still performing as expected. If your refresh rate looks correct but games feel less smooth, check your display settings, graphics driver, and in-game frame cap before blaming the monitor.
FAQs
Is FPS the same as refresh rate?
No. FPS (Frames Per Second) measures how many frames your device renders each second, while refresh rate (Hz) measures how many times your monitor updates the screen. A 144 Hz monitor can still display lower FPS if your browser or hardware cannot render enough frames.
Is this FPS Tester accurate?
Yes. This FPS Tester measures browser-rendered frame delivery, including average FPS, frame time, stutters, and consistency. It accurately reflects your display's performance during the test, although browser limits may differ slightly from full-screen games.
Why does my 120 Hz monitor show 118 FPS?
A 120 Hz monitor showing 118 FPS is normal because browsers and operating systems do not always render every frame perfectly. Small differences of 1-3 FPS are common and usually do not indicate a display problem.
What is a good FPS for gaming?
A good FPS depends on your goal. 60 FPS feels smooth for most games, 120 FPS improves responsiveness in competitive titles, and 240 FPS benefits high-level esports players using fast-refresh monitors.
Why is my FPS lower than my monitor's refresh rate?
Your FPS is usually lower because of CPU load, GPU performance, VSync, background apps, or power-saving mode rather than a faulty monitor. Checking your display settings and graphics driver often fixes the issue.
Does this test work on Mac and mobile?
Yes. The tool works on Windows, Mac, Android, and iPhone through modern browsers like Chrome, Safari, Edge, and Firefox. Results may vary slightly depending on your device, browser, and display capabilities.
