Keyboard Hz Checker
Keyboard Polling Rate Test
Direct answer: a keyboard polling rate test estimates how often your keyboard reports input, shown as Hz. 125Hz is about 8ms, 500Hz about 2ms, and 1000Hz about 1ms between possible updates.
Start the browser test, alternate two nearby keys, and read average Hz, peak Hz, interval, and jitter. It is useful for gaming keyboards, laptop keyboards, and input troubleshooting without installing software.

Result Guide
Convert keyboard Hz into response time.
Polling rate is measured in Hertz. Higher Hz means shorter intervals between input updates, although real-world feel also depends on the keyboard, operating system, game, display, and browser.
About 8ms between updates. Common for basic office keyboards and standard input devices.
About 4ms to 2ms between updates. A solid range for many gaming and performance keyboards.
About 1ms or less between updates. Often advertised on gaming keyboards, but browser readings can vary.
How to run an accurate keyboard polling rate test
键盘轮询率测试答案：键盘轮询率是键盘向电脑报告按键输入的频率，单位是 Hz。125Hz 约等于 8ms 一次更新，500Hz 约 2ms，1000Hz 约 1ms。浏览器测试只能估算键盘事件时间，适合快速比较。
Click Start Test, then rapidly alternate between two nearby keys such as A and S for the full 10 seconds. Alternating keys is usually cleaner than holding one key because held keys can be controlled by your operating system repeat settings instead of raw key input timing.
Keyboard polling rate test steps
Use the same keyboard, browser, and two-key pattern each time. Close heavy background apps, keep the tab focused, press alternating keys quickly, then compare average Hz, peak Hz, interval, and jitter. For broader input checks, run the Keyboard Test and compare hand speed with the Click Speed Test.
What is keyboard polling rate?
Keyboard polling rate describes how often a keyboard reports input updates to the computer. It is usually shown as Hz. A 1000Hz keyboard can theoretically report input every 1 millisecond, while a 125Hz keyboard reports about every 8 milliseconds.
How to read Hz, interval, and jitter
Hz is the estimated number of input updates per second. Interval is the time between detected key events, shown in milliseconds. Jitter is the variation between intervals. A higher Hz, lower interval, and lower jitter usually means more consistent input timing, but browser scheduling and key repeat behavior can still affect the reading.
Mechanical keyboards and gaming use
Many mechanical gaming keyboards advertise 1000Hz or higher polling because fast-paced games benefit from consistent input timing. For everyday typing, the difference between 125Hz, 500Hz, and 1000Hz is often subtle. For rhythm games, shooters, and competitive play, stable intervals and low jitter can matter as much as the headline Hz number.
Keyboard polling rate vs response time
Polling rate is one part of input latency. Response time can also include switch travel, debounce behavior, wireless delay, operating system processing, browser timing, display refresh rate, and the app or game receiving the input.
Browser test limitations
This tool estimates timing from browser key events. It cannot directly read USB hardware polling data, so results can be affected by CPU load, browser scheduling, OS keyboard settings, background apps, and how consistently you press the keys.
Keyboard Polling Rate Test FAQ
What is a good keyboard polling rate?
125Hz is common for basic keyboards, 250Hz to 500Hz is good, and 1000Hz or higher is typical for many gaming keyboards.
What do interval and jitter mean?
Interval is the time between detected key events. Jitter is how much that interval varies; lower jitter usually means steadier timing.
How do I test my keyboard Hz?
Start the test, focus the panel, then rapidly alternate between two keys such as A and S for 10 seconds.
Can a browser test the real keyboard polling rate?
A browser can estimate keyboard event timing, but it cannot directly read raw USB hardware polling data. Treat the result as a practical browser estimate.
Does keyboard polling rate matter for games?
It can matter in timing-sensitive games, but stable intervals and low jitter are often more useful than a high advertised Hz number by itself.
