What is mouse click latency?

Click latency is the delay between physically pressing the button and the system registering the click, measured in milliseconds. Lower is better for gaming.

How is click latency measured here?

Each click event carries a hardware timestamp. We compare it to the moment our code runs using the high-resolution performance clock and average several samples.

What is a good click latency?

In-browser, under about 5ms is great and under 9ms is good. Rising latency over time can indicate background load or hardware wear.

Mouse Click Latency Test

Measure the milliseconds between your click and the system registering it — a number no other DPI site shows you.

Press Start, then click the pad repeatedly.

What this measures. A browser can't see your monitor or USB cable, so this is the input-to-processing latency inside your system, not total click-to-photon latency. It's still an excellent way to compare devices and to track whether your latency is creeping up over time.

Click Latency FAQ

Why does latency matter?: In fast games, every millisecond between intent and action counts. Lower, more consistent latency feels snappier and more reliable.
How do I lower it?: Use a 1000Hz polling rate, close background apps, disable mouse acceleration, and prefer a wired or high-quality wireless connection. Full guide: Mouse Click Latency explained.
My numbers jump around — why?: Background CPU load and browser scheduling add noise. Run it a few times with other apps closed for a cleaner reading.
