What Is a Good Reaction Time? Benchmarks by Age, Sport, and Percentile

The short answer: for a healthy adult, a good visual reaction time is 200–250 milliseconds. Under 200 ms is genuinely fast — the range where athletes and dedicated gamers live. Over 300 ms usually means something is off: fatigue, distraction, or a task you haven't warmed up on.

But "good" is not one number. It depends on your age, the exact task, and how you're testing. This guide answers the specific questions people actually ask about what counts as a good score — with real benchmarks for each. Get your own number first on the reaction time test, then find where it lands below.

What is the average reaction time?

The average simple visual reaction time for healthy adults is around 250 milliseconds[1] — a quarter of a second between the screen turning green and your click registering. Large online datasets of millions of trials cluster in the 250–270 ms range, slightly higher than tightly controlled lab studies because real people test on varied hardware, distracted, and often tired.

So if you're right at 250 ms, you're exactly average. That's the baseline every other benchmark below is measured against.

What counts as a good, fast, or elite score?

Here's the practical breakdown for a healthy adult aged roughly 20–40 on a simple visual click test:

| Your average | Verdict | Percentile | |---|---|---| | Under 180 ms | Elite | Top 1–2% | | 180–200 ms | Excellent | Top 5% | | 200–230 ms | Good | Top 25% | | 230–270 ms | Average | Middle 50% | | 270–310 ms | Below average | Bottom 25% | | Over 310 ms | Slow | Bottom 10% |

A "good" reaction time — one that beats most people — starts around 230 ms and gets impressive below 200 ms. Below about 150 ms on a pure visual task isn't good, it's impossible: the signal can't cross your nervous system that fast, so a sub-150 number almost always means you anticipated the cue rather than reacted to it[2].

A reaction time under 150 ms on a simple visual test isn't elite — it's a false start. Your nervous system physically cannot react to a visual signal faster than about 100 ms, and 150 ms is already near that hard floor.

What is a good reaction time for my age?

Reaction time follows a predictable curve — fast in your 20s, slowly rising after. A "good" score therefore shifts with age. Drawing on population-scale age norms[5], here are rough targets for a good (top-25%) simple visual reaction time by age:

| Age | Good target | Average | |---|---|---| | 10–14 | ~260 ms | ~300 ms | | 15–19 | ~215 ms | ~250 ms | | 20–29 | ~205 ms | ~240 ms | | 30–39 | ~210 ms | ~245 ms | | 40–49 | ~220 ms | ~255 ms | | 50–59 | ~235 ms | ~275 ms | | 60–69 | ~255 ms | ~300 ms | | 70+ | ~280 ms | ~340 ms |

The key insight: a 65-year-old averaging 260 ms is doing better for their age than a 25-year-old at 245 ms, even though the raw number is higher. Judge yourself against your age group, not the population floor. We break the whole lifespan curve down in reaction time by age.

What is a good reaction time for gaming?

For competitive gaming, a good simple reaction time is under 200 ms, and top FPS players cluster around 150–180 ms. But raw reaction matters less than gamers think — most in-game "reactions" are actually predictions, and the gap between a pro and a strong amateur is only about 50 ms. The full breakdown is in our gamer reaction time guide. If you're at 200–230 ms, you're already faster than three-quarters of people.

What is a good reaction time for driving?

Driving is different because it includes perception time — recognizing a hazard — on top of pure reaction. A good total brake reaction time (see the hazard, foot on the brake) is around 700–1,000 ms in real conditions, even though the pure motor component is much faster[3]. The widely used planning figure is about 1.5 seconds, which builds in a safety margin. You can test the specific stimulus profile on the driving reaction time test.

Is audio reaction time faster than visual?

Yes, consistently — by about 30–40 ms. Sound reaches your auditory cortex in 8–10 ms, while light takes 20–40 ms through the visual pathway[4]. So a good audio reaction time is roughly 30 ms faster than a good visual one: around 170–200 ms for a healthy adult. This is biology, not training — the gap holds at every age. Try both on the audio reaction test and compare.

Why is my reaction time slower than it should be?

If you're scoring worse than your age benchmark, the usual culprits, in order of impact:

• Sleep. One bad night adds 100–200 ms — more than four decades of aging. This is the single biggest factor by far.
• Testing cold. Your first few trials run 10–30 ms slow. Warm up with a handful of practice reps.
• Distraction. Background tasks steal from your decision stage.
• Hardware. A 60 Hz display and high input lag can add 20+ ms that has nothing to do with you.
• Time of day and stimulants. You're slower when tired or wired past your sweet spot.

Most "slow" scores are one of these, not a real deficit. Fix sleep and warm up, and most people drop 20–40 ms — see how to improve your reaction time for the full method.

How do I know if my score is real?

A single click isn't a reliable read. To get an honest number:

1. Warm up with 5–10 practice trials.
2. Take at least 5 measured trials and use the average, not your best.
3. Discard obvious false starts (anything under ~120 ms — you guessed).
4. Test rested, at a consistent time of day.

Do that on the visual reaction test and the number you get is one you can actually compare against every table above.

The bottom line

A good reaction time for most adults is 200–250 ms, with under 200 ms being genuinely fast and under 180 ms elite. But the honest answer is always relative: good for your age, on that specific task, tested properly. A well-rested 60-year-old scoring 255 ms is doing better than a tired 25-year-old at 245. Judge yourself against the right benchmark, warm up, and test rested — then the number means something.
