Frame Per Second Calculator

Whether you're a gamer, video editor, animator, or developer, understanding your frame rate is essential for smooth visuals and high performance. That's where our Frame Per Second Calculator comes in handy.

We developed this free, easy-to-use FPS calculator to help you instantly find out how fast your system or video is running. Whether you want to calculate how many frames occur per second, convert frames to seconds, or analyze the performance of your rendering engine, this tool has you covered.

What Is FPS (Frames Per Second)?

Frames Per Second (FPS) is the number of frames or images displayed every second in a video or game. Higher FPS means smoother visuals.

For example:

• 30 FPS is common in standard videos.
• 60 FPS is typical for smoother gaming.
• 120 FPS or 240 FPS is used in high-end gaming and slow-motion video capture.

How to Calculate Frames Per Second?

Calculating FPS is simple and depends on how much time it takes to render or display a certain number of frames.

Formula to Calculate FPS

To calculate FPS, you can use:

FPS = Total Number of Frames ÷ Total Time in Seconds

If you know how long each frame takes, you can also calculate:

FPS = 1 ÷ Time per Frame (in seconds)

For example:

• If 1 frame takes 0.016 seconds,
  FPS = 1 ÷ 0.016 = 62.5 FPS
• If you have 240 frames that were rendered in 4 seconds,
  FPS = 240 ÷ 4 = 60 FPS

How to Calculate Frame Duration from FPS?

If you want to know how long each frame lasts, reverse the calculation:

Frame Time (in seconds) = 1 ÷ FPS

Example:

At 120 FPS, each frame takes

1 ÷ 120 = 0.00833 seconds (or 8.33 milliseconds)

How to Use Our Frame Per Second Calculator

We’ve made this tool simple and intuitive. You can calculate FPS using one of the following:

1. Total Frames and Time:

Enter the total number of frames and how long it took in seconds. The calculator will show your average FPS.

2. Time Per Frame:

Enter the duration of a single frame. The calculator will show the FPS instantly.

3. Smoothed FPS:

If you want to average between frame durations using a smoothing factor, our tool can calculate that for more stable readings.

4. Sliding Window FPS:

Paste multiple frame durations (e.g., from performance logs), and the calculator will show average FPS, minimum, maximum, and standard deviation.

Whether you're optimizing a game engine, editing a video, or just curious about your device performance, this calculator makes it easy.

Final Verdict

If you've ever wondered "How do I figure out my FPS?" or "How long is one frame at 120 FPS?", now you know. With this powerful yet simple tool, you can calculate frames per second with just a few inputs. It’s ideal for video editors, animators, developers, streamers, and anyone working with visuals or games.

Frequently Asked Questions (FAQs)

How do I calculate frames per second?

Use the formula:

FPS = Total Frames ÷ Time in Seconds

Or use our calculator by entering frame count and time duration.

What is a good FPS for gaming?

60 FPS is considered ideal for smooth gameplay. Competitive gamers often prefer 120 FPS or higher.

How long is 1 frame in 120 FPS?

At 120 FPS, 1 frame = 1 ÷ 120 = 0.00833 seconds, or 8.33 milliseconds.

Can I convert frames to seconds?

Yes. Use the formula:

Time in Seconds = Number of Frames ÷ FPS

Is this FPS calculator accurate?

Yes, our calculator uses the most accurate industry formulas with options for basic, instant, smoothed, and averaged FPS calculations.
