What Is FPS? A Beginner's Guide to Frames Per Second
FPS (frames per second) measures how smoothly motion appears on your screen. Learn what FPS means, how it affects gaming and video, and why higher isn't always better.
Frames per second (FPS) is one of the most important metrics for understanding how smooth motion looks on a display. Whether you are gaming, watching video, or just scrolling a webpage, FPS determines how fluid the experience feels.
What Does FPS Mean?
FPS stands for frames per second. It counts how many unique images (frames) your screen draws in a single second. A higher number means smoother motion, while a lower number produces a choppy, stuttering effect.
- 24 FPS — the traditional cinema standard
- 30 FPS — common for TV broadcasts and many console games
- 60 FPS — the baseline for smooth gaming and modern UIs
- 120 FPS and above — prized by competitive gamers for low-latency input
Why FPS Matters
Your monitor's refresh rate (measured in Hertz, Hz) sets the upper limit for what you can actually see. If your monitor is 60Hz, it refreshes 60 times per second, so rendering 120 FPS will not look smoother than 60 FPS on that panel. Matching FPS to your refresh rate is the key to a fluid experience.
How to Check Your FPS
You can measure FPS right in your browser using our free FPS Test tool. It uses requestAnimationFrame to count rendered frames in real time, giving you an accurate reading of your display's performance.
Tip: Close heavy tabs and keep hardware acceleration enabled for the most accurate results.
Common FPS Problems
If your FPS is lower than expected, consider these common causes:
- Background applications consuming CPU or GPU resources
- Outdated graphics drivers
- Browser extensions adding overhead
- A monitor refresh rate set below its maximum
Understanding FPS is the first step toward a smoother, more responsive display experience.
