Browser limitation: This tool measures the timing between key events, not raw USB HID reports. Confirm your keyboard's actual 1000Hz or 8000Hz setting in its manufacturer software.
What is keyboard polling rate?
Keyboard polling rate is how often your keyboard reports key presses to your computer, measured in Hertz (Hz). A 1000Hz polling rate means 1,000 updates per second, resulting in 1ms response time between pressing a key and your computer registering the input.
How to Test Your Keyboard Polling Rate
Combine this keyboard Hz test with your keyboard software to check both observed input behavior and the configured hardware report rate:
- Connect your keyboard directly: use a motherboard USB port or the keyboard's recommended wireless receiver.
- Check the configured polling rate: open Razer Synapse, Logitech G HUB, Corsair iCUE, or your keyboard manufacturer's utility.
- Run the online keyboard Hz checker: focus the test area above and tap or alternate keys rapidly for 5-10 seconds.
- Review event timing and stability: compare the observed key-event intervals, jitter, and consistency across repeated tests.
- Verify the true hardware setting: use manufacturer software or a dedicated device-level utility when confirming 1000Hz, 4000Hz, or 8000Hz.
A browser sees individual key presses rather than every USB report, so a lower on-screen event rate does not automatically mean your keyboard is configured incorrectly.
What a Browser Keyboard Hz Test Can Measure
Understand the difference between observed keyboard events and the device's actual USB polling rate.
Observed key-event timing
Available in the browserThe test records when keydown events reach the page. Your tapping speed, operating-system scheduling, and browser processing all influence these readings.
Hardware polling rate
Verify with device softwareYour keyboard's USB controller may report at 125Hz, 1000Hz, or 8000Hz even when you press only a few keys per second. Browser events cannot expose every raw report.
Keyboard scan rate
A separate measurementScan rate describes how often the keyboard checks its switch matrix. It is different from USB polling rate and cannot be measured directly with standard browser key events.
Practical interpretation
Compare consistencyUse the results to spot inconsistent event timing and compare repeated sessions. Confirm exact hardware report rates through your manufacturer's utility or a dedicated device-level tool.

8K Keyboard Polling Rate Test: How to Verify 8000Hz
Check whether your gaming keyboard is configured for 8000Hz and understand what an online test can actually show.
How to check an 8000Hz keyboard
- Confirm 8K support: check the exact keyboard model, firmware, connection requirements, and manufacturer specifications.
- Enable 8000Hz in device software: select the 8K report-rate option in the supported configuration utility.
- Connect directly: use the manufacturer's recommended USB port, cable, or compatible high-speed receiver.
- Compare browser input behavior: run this 8K keyboard polling rate test to observe key-event timing and consistency.
- Verify the true report rate: rely on manufacturer diagnostics or a dedicated low-level utility because a browser cannot read every USB HID report.
An 8000Hz polling rate corresponds to a theoretical 0.125ms report interval, compared with 1ms at 1000Hz. The live browser reading depends on how quickly key events occur and should not be treated as direct proof of an 8000Hz hardware report rate.

Bluetooth
typically 125–250 HzBluetooth introduces protocol overhead that caps effective polling rates. Expect 8–16ms intervals — fine for office use, but not ideal for competitive gaming.
Wired USB
Up to 8000 HzWired connections provide the lowest latency and highest stable polling rates. Required for 4000Hz and 8000Hz ultra-high polling rate keyboards.
USB Hub Warning
May reduce rateSome hubs, adapters, and shared connections can affect compatibility or input consistency. Use the keyboard manufacturer's recommended direct connection when troubleshooting.
Troubleshooting Low or Unstable Readings
Observed browser event rates and hardware polling rates are different measurements. Start with these checks when results look inconsistent.
1000Hz keyboard shows a lower reading?
Check what is being measuredA browser counts the interval between key events, not every USB report. Confirm the 1000Hz setting in manufacturer software before assuming a lower event rate indicates a hardware problem.
High variation / unstable score
Close background appsBrowser-based tests measure JavaScript event timing. Heavy CPU load from other tabs, antivirus scans, or system updates can cause jitter. Run the test in a focused Chrome window with other tabs closed.
Windows 11 vs Windows 10
Driver stack differencesWindows 11 improved USB HID polling reliability. If you see inconsistent results on Windows 10, update your USB drivers or test on Windows 11 for comparison. Some older chipsets also have USB interrupt limitations.
Manufacturer software conflict
Try disabling RGB / macro softwareBackground utilities, overlays, and RGB effects can influence system load and event delivery. Compare repeated browser sessions, and use your device software to confirm its configured report rate.
Frequently Asked Questions
Common questions about keyboard polling rate and this test.
What is keyboard polling rate?
Keyboard polling rate is how often your keyboard reports key presses to your computer, measured in Hertz (Hz). A 1000Hz polling rate means the keyboard sends data 1000 times per second, resulting in 1ms response time between key presses and computer registration.
Does keyboard polling rate affect gaming?
Yes, higher polling rates reduce input lag which can matter in competitive gaming. However, the difference between 500Hz and 1000Hz (2ms vs 1ms) is barely perceptible to most users. The benefit is more noticeable when upgrading from 125Hz to 1000Hz.
What is the best keyboard polling rate for gaming?
1000Hz is a practical standard for competitive gaming because its theoretical USB report interval is 1ms. Rates of 4000Hz or 8000Hz can reduce that interval further, but the real-world benefit depends on the keyboard, game, and system.
Does 8000Hz keyboard make a difference?
The jump from 1000Hz to 8000Hz can improve key press registration in fast-paced games, but the difference is minimal for most users. 8000Hz keyboards require stable USB connections and may increase CPU usage. For most gamers, 1000Hz remains the sweet spot.
How accurate is this browser test?
This tool measures the interval between keydown events received by your browser. It cannot directly inspect raw USB HID reports, keyboard scan rate, or true end-to-end input latency. Use manufacturer software or a device-level utility to confirm the hardware polling rate.
Why is my measured rate lower than expected?
The displayed rate depends on how quickly consecutive key events reach the page. A 1000Hz or 8000Hz keyboard can still show a much lower event rate when keys are pressed slowly, because the browser does not receive every underlying USB report.
Why is my keyboard polling rate unstable?
Variation can come from inconsistent tapping, operating-system scheduling, browser workload, wireless interference, or connection issues. Repeat the test under similar conditions before drawing conclusions about the keyboard itself.
How do I interpret the stability score?
The stability score describes how consistent the observed intervals between your key presses are. It reflects your input rhythm and browser event delivery; it is not a direct measurement of USB polling stability.
Mechanical vs membrane keyboard polling rate?
Most mechanical gaming keyboards support 1000Hz polling, while budget membrane keyboards often run at 125Hz. However, polling rate is determined by the keyboard's controller, not the switch type. Some high-end membrane keyboards also support 1000Hz.
How do I change my keyboard polling rate?
Polling rate is usually set through the keyboard manufacturer's software (Razer Synapse, Logitech G Hub, etc.) or via onboard controls. Some keyboards have a physical switch or key combination. Check your keyboard's manual for specific instructions.
Why does peak rate sometimes exceed the target?
Short bursts of faster event timing can occur due to scheduling variance or burst delivery. Peak rate represents the best-case moment. Compare it with average rate and stability for a realistic assessment of your keyboard's performance.
What is the best polling rate for typing?
For regular typing and office work, 125-500Hz is perfectly sufficient. Higher polling rates (1000Hz+) don't provide noticeable benefits for typing and may slightly increase power consumption on wireless keyboards.
Does manufacturer software affect test accuracy?
Manufacturer software configures the keyboard's hardware polling rate, while this page observes browser key events. Keep the selected setting visible for verification and close unrelated background tasks if they affect event timing.
How do I verify an 8000Hz keyboard?
Check that your exact keyboard model supports 8000Hz, enable the 8K report rate in its configuration software, and use its recommended connection. Verify the hardware setting with manufacturer diagnostics or a device-level utility rather than relying on browser key-event timing alone.
Understanding Your Keyboard Test Results
Learn what the displayed event rate means, how keyboard report rates differ, and when to use dedicated hardware tools.
What a keyboard polling rate test measures
This keyboard Hz checker listens for keydown events and calculates the interval between consecutive physical key presses. The displayed frequency describes observed input events, not the keyboard's raw USB report frequency. Use it to compare event timing, spot irregular input, and check whether keys register consistently during repeated sessions.
Why keyboard polling rate matters for gaming
In competitive games where split-second reactions matter, lower input latency provides an edge. A keyboard configured for 1000Hz has a theoretical 1ms USB report interval, while 125Hz corresponds to 8ms. A shorter report interval can reduce one part of the input chain, but switch behavior, scan rate, operating-system scheduling, and game processing also contribute to total latency.
125 Hz to 8000 Hz: what to expect in practice
125 Hz (8 ms) is typical for basic office keyboards. 500 Hz (2 ms) is a comfortable baseline for gaming. 1000 Hz (1 ms) remains the competitive standard because it balances latency and stability. 4000 Hz (0.25 ms) and 8000 Hz (0.125 ms) are available on premium keyboards, but the benefits are marginal for most users and may introduce stability issues on some systems.
Mechanical vs membrane keyboard performance
The polling rate is determined by the keyboard's USB controller, not the switch mechanism. A mechanical keyboard with a budget controller may poll at 125Hz, while a premium membrane keyboard could support 1000Hz. Check the manufacturer's specifications and active device setting instead of assuming a switch type determines the hardware report rate.
Troubleshooting low readings and instability
- Use the recommended connection: connect directly or use the supported wireless receiver.
- Keep your tapping consistent: irregular key presses create irregular observed event intervals.
- Check software settings: verify polling rate is set correctly in manufacturer software.
- Reduce system load: close heavy background applications during testing.
Keyboard polling rate vs. scan rate
Polling rate describes how frequently the keyboard can send reports to the computer. Scan rate describes how often the keyboard's controller checks its switches for changes. Both influence responsiveness, but neither value can be directly recovered from ordinary browser keydown events.
Keyboard polling rate vs. input latency
A 1000Hz report rate means reports can be sent at 1ms intervals; it does not guarantee that total input latency is exactly 1ms. Switch actuation, matrix scanning, firmware, USB transport, the operating system, and the receiving application all add their own delay.
Windows 11 keyboard polling rate
Windows 11 does not provide a universal Settings control that displays every keyboard's active polling rate. Check the manufacturer's configuration utility for the selected report rate and use a compatible device-level diagnostic tool when independent hardware verification is needed.
