Frame Time Calculator
Frame rate tells you how many frames you get each second. Frame time tells you how long each one takes, which is what you feel as smoothness and responsiveness. Enter either figure to get the other.
Each frame takes
6.94 ms

| 120 FPS | 8.33 ms | – |

Why frame time matters. The jump from 30 to 60 FPS saves 16.7 ms on every frame; the jump from 144 to 240 FPS saves under 3 ms. That's why each step up in refresh rate feels smaller than the last, and why steady frame times matter more than a high average.
Make sure your monitor really runs at its full rate with our guide to setting your monitor's refresh rate, and see how to reduce input lag for the rest of the delay between your hand and the screen.
How this works
- Frame time in milliseconds = 1,000 ÷ frames per second. It works the other way too: FPS = 1,000 ÷ frame time.
- The comparison table applies the same formula to common refresh rates, and shows how many milliseconds each one saves per frame compared with your figure.
- For a frame rate cap, it shows how many whole frames fit in each refresh of your monitor: refresh rate ÷ FPS.
Frame time is the average gap between frames. It says nothing about stutter, where a few frames take much longer than the rest, or about the total delay between your input and the screen.
Where the figures come from: The definition of frame rate: one second is 1,000 milliseconds.
