Average Reaction Time
What is normal, what is good, and what is truly fast? Across lab studies, human reaction time to a visual signal averages about 190 ms. In a browser on consumer hardware, most people land between 250 and 275 ms. Here is how results break down by age, stimulus, and hardware.

Technology
Why Online Tests Read Slower Than the Lab
Hardware delay accounts for 30 to 70 ms of additional latency on consumer PCs and phones.
Display Refresh Lag
At 60 Hz, frames are drawn every 16.7 ms. On a 144 Hz or 240 Hz gaming monitor, frame intervals drop to 6.9 ms or 4.2 ms, cutting visual latency significantly.
Touchscreen Digitization
Touchscreens scan for fingers at discrete polling intervals, adding 20–40 ms compared to wired optical gaming mice.
Population Data
Reaction Time Ratings & Benchmarks
How simple visual reaction time breaks down across the general population.
| Average | Rating | Faster than about |
|---|---|---|
| < 160 ms | Superhuman | Top 0.5% (rare on consumer displays) |
| 160 – 190 ms | Elite | Top 5% (esports pros & athletes) |
| 190 – 220 ms | Excellent | Top 20% |
| 220 – 260 ms | Good | Above median (top 45%) |
| 260 – 300 ms | Average | Typical healthy adult range |
| 300 – 360 ms | Below average | Slower than 75% |
| > 360 ms | Sluggish | Bottom 10% |
Percentages derive from a log-normal distribution model with a median of 250 ms, calibrated against real browser testing environments.
Demographics
Reaction Time by Age Group
Simple reflexes peak in the early twenties and decline gradually across adulthood.
| Age Group | Simple Reaction (Flash) | Choice Reaction (Decision) |
|---|---|---|
| 10 – 14 years | 270 – 310 ms | 480 – 550 ms |
| 15 – 19 years | 230 – 260 ms | 400 – 450 ms |
| 20 – 24 years | 210 – 240 ms | 380 – 420 ms |
| 25 – 34 years | 230 – 260 ms | 400 – 440 ms |
| 35 – 49 years | 250 – 280 ms | 430 – 480 ms |
| 50 – 64 years | 280 – 320 ms | 470 – 530 ms |
| 65+ years | 320 – 380 ms | 540 – 620 ms |
Sensory Modality
Auditory vs Visual vs Haptic Reactions
The human nervous system responds at different speeds depending on which sensory organ receives the stimulus.
| Stimulus Modality | Lab Average (Zero Latency) | Normal Adult Range |
|---|---|---|
| Sound (Auditory beep) | 150 ms | 130 – 180 ms |
| Touch (Haptic vibration) | 160 ms | 140 – 190 ms |
| Light (Visual flash) | 190 ms | 170 – 230 ms |
| Choice Visual (2 options) | 350 ms | 300 – 450 ms |
