How keyboard latency works

Keyboard latency is the wait between a key counting as pressed and your PC receiving that press. When a box says “1 ms”, it almost always means a 1000 Hz polling rate: the keyboard sends a report every millisecond. That’s one link in the chain, not the full delay from your finger to the screen. The game, the PC and the monitor all add their own wait after the report arrives.

So the practical rule is short: play on a cable or a 2.4 GHz dongle at 1000 Hz, and keep Bluetooth for typing. Past that, pick the best gaming keyboard for its layout and switches, not for a bigger number on the box.

The four waits in a key press

Only one of these is the hertz on the box. Listings that say “1 ms keyboard” blend them together.

Before the keyboard has anything to send

The first wait is distance. The actuation point is how far a key travels before it registers, and a shorter point counts after less finger movement. It never shows up in the polling number, because until the key counts there’s nothing to report.

Then comes debounce. A metal contact can bounce for a moment when it closes, so the controller waits until it reads steady before accepting one press. Brands rarely print this number. A Hall effect or optical switch has no metal contact to bounce, so that pause disappears. It still doesn’t raise the polling rate, so check that separately.

The math behind the number on the box

The gap between reports is 1000 divided by the polling rate in Hz. That’s the whole calculation.

The rate depends on the connection. A rate listed for USB doesn’t apply over Bluetooth, which is often the link with no 1000 Hz mode at all. A 2.4 GHz wireless dongle can match the cable. Set the rate in the keyboard’s software while it’s on the connection you’ll actually play on.

Some pages also list a scan rate: how often the controller checks the keys internally. A fast scan still waits for the next report to leave, so if a page shows a huge scan rate but no USB polling rate, it’s advertising the wrong number.

What doesn’t make the keyboard faster

Rapid trigger resets a key as soon as you start lifting it, which makes fast taps and counter-strafes register sooner. That’s a real advantage for movement, but the report still goes out at the same polling rate.

Switch type isn’t latency either. Linear, tactile and clicky describe how the press feels. N-key rollover decides how many keys fit in one report, not when it leaves. Board size doesn’t matter: a full-size and a 60% board can run the same 1000 Hz. See TKL vs 60% vs full-size if size is the real question.

After the report arrives

The game has to process the press and the monitor has to draw it. A 60 Hz screen can only show a new frame every 16.7 ms, no matter how often the keyboard reports. I play on two 27-inch monitors, a 1080p 240 Hz and a 1440p 155 Hz, and the refresh rate of the screen in front of you matters far more than 1000 Hz versus 8000 Hz on the keyboard.

If a key still feels late, change one thing at a time: a shorter actuation point if your board supports it, or a faster screen. Don’t buy another keyboard that lists the same 1000 Hz and expect a difference.

Keyboards worth a look

I play left-handed on UHJK, so I care about layout first. All three of these hit 1000 Hz on a wired or dongle connection.

• Wireless TKL: Logitech G PRO X TKL LIGHTSPEED. Logitech’s spec sheet lists a USB report rate of max 1 ms (1000 Hz), up to 50 hours of battery and GX switches. Official US price $189.99. Logitech spec sheet. Amazon search for PRO X TKL LIGHTSPEED
• 60% with rapid trigger: Wooting 60HE, official price $174.99. Hall effect switches, so no debounce, plus rapid trigger for movement. The catch is the 60% layout: the F-row moves to a layer, which matters more in WoW than in shooters. My Naga covers those binds, so it works for me. Amazon search for Wooting 60HE
• Budget full-size: Logitech G413 SE. Official $89.99, wired, tactile mechanical switches, PBT keycaps, 6-key rollover. Logitech G. Amazon search for G413 SE

Common questions

What is keyboard latency?

It's the delay between a key registering as pressed and your computer receiving it. It's different from how far the key travels. When a box says 1 ms, it usually means a 1000 Hz polling rate, not the full delay to your screen.

What does 1000 Hz polling rate mean on a keyboard?

It means the keyboard sends updates 1000 times a second, so there's 1 ms between reports. A 125 Hz keyboard waits 8 ms between reports. Your game and monitor add their own delay on top.

Do Hall-effect keyboards have lower latency?

Slightly, in one way. They don't need debounce time like metal-contact switches, so presses can register a bit faster. They don't change the polling rate, though.

Does rapid trigger reduce input lag?

It makes keys reset faster when you lift, so repeated presses register sooner. It doesn't change the polling rate, but it does make fast strafing feel much more responsive.

Is a Bluetooth keyboard slower for gaming?

Yes, usually. Bluetooth rarely reaches 1000 Hz, so use a cable or 2.4 GHz dongle for gaming and save Bluetooth for typing.

Will a low-latency keyboard improve my gaming?

Only a little, if your current keyboard already runs at 1000 Hz. If keys still feel late, look at actuation point and your monitor's input lag first. Another 1000 Hz keyboard won't feel much different.
