Is 340 ms reaction time good?
A 340 ms average on a simple visual reaction test is slower than the typical adult — and very trainable. That's 67 ms behind the average adult — noticeable in a duel, and very fixable with a few weeks of short daily practice.
Human reaction time to a visual stimulus follows a bell curve with an average around 273 ms and a standard deviation of about 60 ms. Plug 340 ms into that distribution and you land ahead of roughly 13.2% of the population — the verdict: below average.
How 340 ms compares
| Who | Typical reaction time |
|---|---|
| Pro esports player | 170 ms |
| F1 driver (start lights) | 200 ms |
| Average gamer | 230 ms |
| Average adult | 273 ms |
| Average at age 60+ | 330 ms |
| You — 340 ms | 340 ms |
The gap to the average adult (273 ms) is 67 ms. That sounds like a lot, but untrained reaction time responds quickly to practice — the first 30 ms are the easiest you'll ever win.
What 340 ms really means
Below the adult average of ~273 ms, but before reading anything into that: a single reading of 340 ms is often the device or the setup, not you. High touch latency on older phones, a laggy display, or reacting while distracted can add 50+ ms on their own.
Age matters too — this is a completely normal average for healthy adults around 60, and for kids under 12 whose nervous systems are still developing speed.
What affects your reaction time
- Age. Reaction time is fastest around your mid-20s and drifts a few milliseconds per decade after that — see the age curve.
- Hardware latency. A 60 Hz screen adds up to 16 ms of display delay versus ~4 ms at 240 Hz; cheap mice and old touchscreens add more.
- Warm-up. Your first three attempts of a session are reliably your worst. Never judge yourself cold.
- Caffeine. One coffee speeds you up 3–7% for a few hours. Three coffees make you fast and wrong.
How to get faster from 340 ms
Retest properly first: same device, ten rounds, warmed up, no distractions. Many people "gain" 40 ms just by testing right.
Then train small and often — 5 minutes a day beats an hour on Sunday. Untrained reflexes respond fast: 10–15% improvement in a month is typical.
