What Is FPS?
Frames per second, or FPS, describes how many individual frames are rendered or displayed every second. Higher frame rates can create smoother-looking motion, especially in gaming, animation and high-refresh-rate displays.
Each frame is a still image. When displayed in rapid sequence, they create the perception of smooth, fluid movement. The speed at which this happens — measured in frames per second — directly affects how motion appears on your screen.
FPS & Human VisionA Simple Way to Understand Your Frame Rate
Everything you need to observe and compare frame rates, directly in your browser — no setup required.
Instant Browser Testing
Start testing without installing software, drivers or browser extensions. Open the page and the test is ready to run.
Compare Frame Rates
Compare common frame rates including 30, 60, 120, 144 and 240 FPS to see how each level appears on your display.
Real-Time Experience
Observe frame-rate behavior and motion directly in your browser as it happens, without delays or buffering.
Built for Modern Displays
Useful for desktops, laptops and high-refresh-rate monitor setups running at 60 Hz, 120 Hz, 144 Hz and beyond.
30 FPS vs 60 FPS vs 120 FPS vs 144 FPS vs 240 FPS
Different frame rates can feel noticeably different depending on your display, browser, hardware and content. Use our FPS tester to see them in action.
Common in some video content and lower-performance scenarios.
Widely used and generally perceived as smooth for many experiences.
Provides smoother motion when paired with compatible hardware and displays.
Common on gaming-oriented high-refresh-rate monitors for fluid gameplay.
Used with high-refresh-rate displays for extremely fluid motion.
How to Test FPS Online
Get started in seconds. No accounts, extensions or downloads needed.
Start the Test
Launch the FPS test directly in your browser. No installation, download or account required.
Compare Frame Rates
View different FPS levels and observe motion smoothness across 30, 60, 120, 144 and 240 FPS.
Review the Difference
Use the visual comparison to understand how different frame rates appear on your own display.
See the Difference Yourself
Frame-rate differences are often easier to understand when you can see them directly. Run the FPS test and compare different frame rates on your own screen.
Why Does FPS Matter?
Frame rate affects how motion appears across a range of different scenarios and display setups.
Gaming
Higher frame rates can make motion appear smoother when the hardware and display support them, which may improve perceived responsiveness.
Monitors
A monitor's refresh rate determines how frequently the display can update the image. Understanding this helps you match your hardware appropriately.
Video & Animation
Frame rate influences how movement appears across video, animation and interactive content — from standard broadcast to high-frame-rate video.
Performance Testing
FPS measurements can help users understand rendering behavior, motion consistency and how their system performs under different conditions.
FPS vs Hz: What's the Difference?
These are two related but distinct measurements. Understanding both helps you get the most from your display.
FPS
Frames Per Second
The number of frames rendered or produced every second by your system. This is a measure of output performance — how many frames your GPU or browser generates per second.

Refresh Rate
The number of times a display can refresh its image each second. This is a hardware specification of your monitor — a 144 Hz display refreshes 144 times per second regardless of FPS output.
Learn About Refresh RatesImportant: Rendering 240 FPS does not mean a 60 Hz display can physically show 240 unique screen refreshes every second. Your display's Hz limit determines the maximum number of unique frames it can physically show per second.
What Users Say About FPSTestR
Feedback from people who have used the tool to compare frame rates.
"I've been building PCs for years and always struggled to explain the difference between 60 and 144 FPS to friends. This tool finally gave me a way to show them side by side in a browser. No downloads, no fuss — just open and compare. It's now my go-to link whenever someone asks why high refresh rate matters."
"I was about to spend $400 on a 144 Hz monitor and wanted to know if it was actually worth it. Running the FPS comparison on my current 60 Hz display made the difference obvious. The tool is clean, fast, and works perfectly in Chrome. I've recommended it to several coworkers since."
"As a video editor, I frequently need to explain frame rate differences to clients who don't come from a technical background. This tool lets me pull up a visual comparison instantly during a call. The 30 vs 60 vs 120 FPS breakdown is especially helpful. Would love to see a 24 FPS cinema option added eventually."
