What Is The Keyboard Latency Test?

Are you someone who uses a keyboard a lot? If so, a key press latency test is required. A performance test called a keyboard latency test analyzes how long it takes for a key to be pressed and for the matching character to display on the screen. The test evaluates how quickly the keyboard control system sends a signal to the computer, how quickly the computer processes that signal, and how quickly the computer displays the character that corresponds to the screen.


The user’s experience when typing is impacted by keyboard latency. A high latency keyboard can cause missed keystrokes, mistakes, and slower typing. For gamers, a high latency keyboard might cause a delay between pressing a key and the game action taking place.


Therefore, take the keyboard benchmark latency test to be sure it is operating at its best. Any keyboard, including mechanical and membrane keyboards, can be put through these tests, which help judge the keyboard’s overall performance.

Keyboard Scan Rate Test:

Keyboard scan rate has a role in the latency of a keyboard and spacebar counter test. The speed at which a keyboard can recognize and record inputs are measured by a keyboard scan rate test (measured in Hz). It calculates the frequency with which the keyboard controller scans the keyboard matrix to find key presses.

The keystrokes that can be recorded per second are determined by the keyboard scan rate. For rapid typists or gamers, a high scan rate keyboard is essential since it can register several keystrokes simultaneously without missing any of them. The maximum number of keystrokes that may be recorded per second, sometimes referred to as the keyboard rollover rate, is how the test findings are expressed.

In terms of scan rate, all keyboards have been made equal parts keyboards’ lower scan rates make it possible that they won’t be capable to record many keystrokes at once without missing part of them. Specifically for quick typists or gamers, this can result in missed keystrokes, mistakes, and decreased typing speed. Test the keyboard’s scan rate to make sure it is operating at its best.

Measuring Your Keyboard Latency:


Test keyboard latency and know about the scan rate by following the lower procedure:

  • Scroll up to the test at the top of the page.
  • Press any key on your keyboard. It is not necessary to press the key that has the alphabet on them. You can press any key of your choice.
  • After pressing the key, the response time and scan rate will appear on the screen.
  • If you press another key, the response time of the second key will appear next to the first key, and the same goes on if you keep pressing.
  • Users can have a look at the history of all keys that were pressed.

What Affects the Efficiency of Keyboard Latency Testers?

Does this never come into your mind why one keyboard has a higher latency rate while the other has a lower one? Based on this fact, there is some factor that affects the latency of a keyboard. I have jotted down a few points here:

1. Scan Rate:

The frequency at which a device scans for signals is known as the scan rate. Lower keyboard latency might result from a device’s ability to scan for signals more quickly at a greater scan rate. As a result, scan rate has a significant impact on keyboard latency and other tests such as the keyboard speed test.

2. Polling Rate:

A device’s polling rate is the frequency with which it transmits and receives data packets. Lower latency might result from a device transmitting or receiving data more frequently, which is indicated by a greater polling rate. The majority of systems poll at 1000 Hz.

3. Response Time:

A device’s response time to a signal or data packet is referred to as the response time. A shorter latency can result from a quicker response time. Lower response times are caused by higher scan and poling rates.

4. Connection Type:

How devices are connected can also have an impact on latency. For instance, compared to a wireless connection, a wired connection is typically faster and more dependable.

5. Dirty Keyboard:

Results could be delayed if there is dirt on the keyboard’s keys. Make sure there are no dirt or other filthy particles on the keyboard you are using. Use a good keyboard as well.

Frequently Asked Question:

1. What Is The Key Scan Rate Test?

The key scan rate test gauges how rapidly a keyboard can recognize and interpret several keystrokes. It establishes the most keystrokes that can be recorded in a certain amount of time.

2. How Do I Check The Input Delay On The Keyboard?

One can employ a keyboard input lag test online or keyboard latency tools to determine the keyboard’s input delay. The time required for the keystroke to be recorded and seen on the screen is often displayed by these tools. To test if the delay still occurs, you can also try connecting the keyboard to a different USB port or computer. Updates to the firmware or keyboard driver may also aid in minimizing input lag.

3. How Much Latency Does A 1000Hz Keyboard Have?

The latency of a 1000Hz keyboard is 1 millisecond (ms) or less. This results in an extremely quick and responsive typing experience because it can register and process key presses at a rate of 1000 times per second.

4. Is 125Hz Better Than 1000Hz?

No, 1000Hz is typically seen as being superior to 125Hz since it offers a quicker and more precise input.
