Reaction Time Ages 20–29
The average reaction time for ages 20–29 is 245 milliseconds. See the full distribution, what's normal for this age, and how to improve.
What 245 ms means for ages 20–29
The reference group most online reaction time studies use. Roughly 250 ms is the global median for this cohort on a clean monitor with a wired mouse.
The 245 millisecond average for ages 20–29 sits at the 54th percentile of the overall adult population. That means the typical ages 20–29 is faster than 54% of all adults. Whether that is a flattering comparison depends on which direction the age curve runs from here — see the ages 14–19 and ages 30–39 groups for context.
How to interpret your own score
If you are in this age group and you scored within 30 ms of 245, you are completely typical — there is nothing to fix. If you scored under 200 ms, you are in the top 5% of your peers, which is genuinely fast. If you scored over 305 ms, you are in the bottom 5%, but before you worry, rule out the usual suspects: fatigue, screen brightness, mouse latency, and any medications you might be taking.
Single results are noisy. Take the test below 3–5 times and look at the average rather than any individual attempt.
