Pro Gamer Reaction Times
The famous numbers are wrong. Here is what the research actually measured.

Search this question and the same numbers come back everywhere: pros react in 130–150 ms, TenZ has been clocked at 138 ms, sub-150 ms is "pro-tier." Almost none of it holds up. When esports players are tested on standardised equipment, the numbers that come back are 220–290 ms — not meaningfully different from ordinary trained athletes who don't play competitively at all.
Where "138 ms" actually comes from
The 138 ms figure attached to TenZ traces to a single click, made once, during a livestream, and self-reported rather than measured under controlled conditions. It is the best result out of an unknown number of attempts, not an average and not a scientific measurement of anything. Treat any pro-gamer reaction time you see quoted to the millisecond, with a name attached, the same way — unless whoever is quoting it can name the test and the sample.
What controlled testing actually finds
Saygı and Odabaş (2023) put esports players through a standardised reaction test and got a mean of 229.5 ms. They ran the same test on sports-science students who don't play competitively and got 229.5 ms back — identical, with a p-value of .999, about as clean a null result as this kind of testing produces. Bickmann and colleagues (2021) used the Vienna Test System, a validated instrument built for exactly this measurement, and found no significant difference between professional or amateur esports players and traditional athletes. Rogers and colleagues (2024) measured competitive FPS players directly and got 290.8 ms.
Put together, the standardised range for esports players is roughly 220–290 ms — slower, on average, than the popular claims, and not distinguishable from non-gamers tested the same way. That is the finding, not a hedge: the best available evidence says reaction speed is not what makes elite players elite.
If it isn't reaction speed, what is it?
That's the obvious next question, and we would rather give you the honest answer than a better-sounding one. The research above is good at ruling things out: it tells us elite players are not reacting to a stimulus meaningfully faster than anyone else who trains. It is much thinner on what actually separates them, because that is a harder thing to isolate than a single reaction-time trial.
We are not going to hand you a replacement number — something like "game sense is worth 40 ms" — because no study we can point to measures that. If a page tells you otherwise with a precise figure attached, ask what the study was.
Test your own number
- A healthy adult reacting to a plain visual cue averages 210–230 ms under laboratory conditions, from a study of 1,469 people (Woods et al., 2015).
- Our own Reaction Time Test measures that same kind of simple reaction inside a browser, which adds some hardware lag on top of the lab figure.
- FPS Aim Trainer, linked above, measures a moving target you have to track and fire on — closer to a real peek, and a different number entirely from a plain reaction test.
Compare your result against your own past scores, on the same device, rather than against anyone else's number. That is the only comparison a browser test really supports.
Frequently asked questions
What is a pro gamer's actual reaction time?
Roughly 220–290 ms on standardised tests, across multiple independent studies (Saygı & Odabaş, 2023; Bickmann et al., 2021; Rogers et al., 2024). That is slower than the 130–150 ms figures that circulate online, and close to what trained athletes who don't play competitively score on the same tests.
Is TenZ's 138 ms reaction time real?
Not as a measurement. It comes from a single self-reported click during a livestream — the best result from an unknown number of tries, not an average from a controlled test. It has been repeated often enough to read like a fact, but nobody measured it the way a reaction-time study measures anything.
Do professional gamers have faster reflexes than non-gamers?
The best studies say no. Saygı and Odabaş (2023) found esports players and sports-science students scored identically — 229.5 ms each, p = .999. Bickmann et al. (2021), using the validated Vienna Test System, found no significant difference between esports players and traditional athletes either. Reaction speed does not appear to be where pros are unusual.
If reaction time isn't what makes pros elite, what does?
The honest answer is that the research is much better at telling you what it isn't than what it is. It rules out raw reaction speed. It doesn't hand us a validated, measured replacement, and we would rather say that plainly than invent one.
What's a normal reaction time for the rest of us?
Healthy adults average 210–230 ms to a simple visual cue under laboratory conditions, from a study of 1,469 people (Woods et al., 2015). Browser-based tests usually read slower than that, because your screen and mouse add their own delay on top of the reaction itself.
Should I trust reaction-time claims attached to named pro players?
Ask what test produced the number and how many attempts it came from. A single click on a stream, or a figure with no named study behind it, is a claim, not evidence. Most of the specific millisecond numbers attached to named pros online fail that test.
