Keyboard polling rate test
Press any key to start. This free keyboard polling rate test measures the gap between key events in milliseconds — mash keys for 10–15 seconds and read min interval, last interval, and a live ms graph.
Free keyboard polling rate test — key intervals in ms
TestMyGears measures time between keydown events while you mash the board. Min interval, last interval, an ms history graph, and an event log help you compare ports and settings — without a mouse Start button, and with an honest limit: web pages cannot read silent USB polls.
ms vs key-repeat
Holding one key triggers OS auto-repeat (~30–50 ms gaps). That is not HID polling. Mash or roll keys so each press is a fresh keydown.
1 ms / 2 ms / 8 ms tiers
~1 ms ≈ 1000 Hz, ~2 ms ≈ 500 Hz, ~8 ms ≈ 125 Hz. Office boards often sit near 8 ms; gaming firmware aims lower.
Browser measurement limits
This estimates delivery of key events to JavaScript. Scheduling and focus add variance — use it as a relative meter.
When to open vendor software
If min interval stays high after a wired mash pass, raise report rate in QMK/VIA or the maker app, then retest.
When to use this test
Gaming keyboard interval check
Confirm whether a “1000 Hz” board delivers ~1 ms key gaps after enabling high polling in QMK/VIA, Synapse, or Wootility — then retest on another USB port.
How to test keyboard polling rate without installs
Press keys in the browser pad for a quick ms read before installing vendor tools. No Start button — typing begins the run.
Membrane vs mechanical comparison
Run the same mash pattern on two boards. Min interval and log stability often differ even when both boxes claim 1000 Hz.
How to run a keyboard polling rate test
About one minute: press a key to start, mash, read min ms, then retest after any USB or firmware change.
-
Press any key to start
No mouse Start button. Keep this tab focused and type — the first keydown begins listening.
Turn off sticky keys and close overlays before you mash
-
Mash across keys
Roll fingers across ASDF for 10–15 seconds. Different keys beat holding Space.
Wired motherboard ports usually give cleaner min intervals than hubs
-
Read min ms and the log
Min detected interval is your best gap so far. The graph and event log show whether delivery stays stable.
Reset, change one setting, then retest so you know what moved the number
Tips for cleaner keyboard interval reads
-
Use a direct motherboard USB port — avoid unpowered hubs when comparing boards.
-
Disable extensions that inject key handlers if intervals look oddly capped.
-
Retest after raising polling in firmware; keep the same mash pattern.
-
Pair with the key chatter test if double letters appear while you mash.
Keyboard polling rate test FAQs
What is a keyboard polling rate test?
It estimates how often key activity reaches your PC. This page shows that as the time between key events in milliseconds. About 1 ms between events is roughly 1000 Hz; 8 ms is roughly 125 Hz.
Why show ms instead of Hz?
Interval in ms is what you actually measure between keydowns. Hz is just 1000 ÷ ms. Showing ms makes short gaps (0.1–2 ms) easier to compare than large Hz numbers that browsers often cannot reach.
How do I test keyboard polling rate online?
Open this page and press any key to start. Mash different keys for 10–15 seconds and read min interval in ms. No mouse click is required to begin.
Is a browser keyboard polling rate test accurate?
It is accurate enough for relative checks between boards and ports. It cannot certify USB HID firmware rate — browsers do not expose silent HID polls.
Why is my min interval stuck around 8–30 ms?
Holding one key only measures OS key-repeat. Mash across keys, use a wired port, raise polling in vendor software, and avoid USB hubs.
Keyboard CPS vs keyboard polling rate — what is the difference?
CPS counts how fast you tap. Polling / interval measures time between key events reaching the page. Use CPS for speed benchmarks; use this page for ms gaps.
Can I use this instead of keyboard polling rate test software?
Use this for a quick free online pass. Manufacturer software is better when you need an official USB report-rate setting for RMA or competitive configs.
Is this a mouse or controller polling rate test?
Keyboard only — press keys to start. For mice, use the mouse polling rate test. Controller polling is a separate tool.
