Average Reaction Time by Age

Based on studies using simple visual reaction time tests, here are the broad averages across age groups:

• Ages 6–12 (Children): 270–340 ms
• Ages 13–19 (Teenagers): 220–270 ms
• Ages 20–30 (Young Adults): 190–250 ms
• Ages 31–40: 210–260 ms
• Ages 41–55: 240–290 ms
• Ages 56–70: 270–330 ms
• Ages 71+ (Seniors): 310–400 ms

These ranges represent average, untrained individuals. Athletes, gamers, and people who practice regularly often score 40–80 ms faster than these baselines at every age group.

Reaction time follows the classic developmental curve seen in other cognitive abilities. During childhood, the brain's neural pathways are still maturing — myelination (the insulating process that speeds nerve conduction) is incomplete until the mid-20s. This is why teenagers are typically faster than young children.

The peak window for raw reaction time is roughly ages 18–28. After that, gradual changes in neural processing speed, sensory acuity, and motor control progressively add milliseconds. By age 60, average reaction time has typically increased by 30–50 ms compared to peak, though this varies enormously by individual.

Crucially, this age-related decline is not inevitable — it is largely modifiable. Regular cardiovascular exercise, cognitive engagement, and reaction-specific training all measurably slow or reverse the age-related increase in reaction time.

Elite athletes in fast-reaction sports often score in the 120–180 ms range under controlled conditions. Formula 1 drivers have been measured at around 200 ms — surprisingly average for a general population — but their advantage lies in anticipation and scenario reading, not raw reflex speed.

Professional esports players in titles like Valorant and CS:GO average 150–180 ms on in-game measurables, though these numbers include motor preparation time that differs from simple lab reaction time.

What separates elite performers from average people is not purely faster raw reflexes — it is also pattern recognition, anticipatory processing, and decision-making speed. These are all trainable.

Your reaction time on any given day is influenced by several short-term factors that can shift your score by 20–80 ms:

Sleep: Even one night of poor sleep (less than 6 hours) adds 30–70 ms to average reaction time, comparable to moderate alcohol intoxication.

Caffeine: One to two standard caffeinated drinks can improve reaction time by 10–20 ms in fatigued individuals. Effect is minimal in well-rested, non-habitual users.

Time of Day: Most people react fastest in the mid-to-late afternoon (2–6 PM), when core body temperature is highest. Morning reaction time is typically 20–30 ms slower.

Alcohol: Even at a blood alcohol level of 0.05% (below the legal driving limit in many countries), reaction time increases by 50–100 ms on average.

Hydration: A 2% loss of body water can impair cognitive function and add 15–30 ms to reaction time.

Being "average" in reaction time is not a failure — it means your nervous system is working exactly as expected for your age and lifestyle. Average adults successfully drive, play sports, and perform countless precision tasks every day.

If you want to improve, the most effective interventions are: consistent daily practice on reaction-specific tasks (like our test), regular aerobic exercise, and prioritizing sleep. Most people can move from the average range to the "above average" bracket within 4–6 weeks of dedicated effort.

More importantly, understanding where you start gives you a meaningful baseline. Play our test, record your first 5-round average, and return in three weeks. The data will tell you exactly how much you have improved.
