Research and score interpretation
Average human reaction time: research and your score
What is the average human reaction time?
Woods and colleagues reported average visual reaction times of 231 ms and 238 ms in two controlled experiments. The average depends on the task, participants and equipment. These study results provide a specific reference for interpreting the measurement.
Reaction time runs from a cue to a response; 250 ms is a quarter of a second. See the published results and methods before comparing them with a browser score.
Compare your set with the reaction time score comparison guide, learn the visual reaction test method, and follow a reaction-time practice plan. The reaction time guide library connects the topics.
Published visual reaction time results
The table summarizes two experiments in Woods et al. (2015). The study used controlled cue presentation and calibrated equipment. Its samples, tasks and number of trials differ from the five-attempt browser exercise on this page.
| Experiment | Participants | Age range | Mean time | Recorded trials per participant |
|---|---|---|---|---|
| Experiment 1 | 1,469 | 18–65 | 231 ms | 120 |
| Experiment 2 | 189 | 18–82 | 238 ms | 100 |
Experiment 1's mean was 213 ms after its measured hardware correction. That correction belongs to the study equipment. Subtracting it from your own score would not calibrate your device. See our display and input latency guide.
Average reaction time by age: what the evidence tells us
These selected adult groups come from Table 2 of Woods et al. (2015). They report recorded simple visual reaction times before the study's hardware correction. The experiment included 1,469 adults and 120 recorded trials per participant.
| Age (years) | Participants in group | Mean visual reaction time |
|---|---|---|
| 18–24 | 86 | 217.9 ms |
| 39–45 | 273 | 227.7 ms |
| 59–65 | 246 | 239.1 ms |
The study measured a defined visual task on its own equipment. A good reaction time in ms for your age cannot be inferred from these group means alone, especially with a different device or task. The adult data does not establish a benchmark for children or teenagers.
In the first experiment, the authors found an age-related increase of about 0.55 ms per year across their adult sample. This is a statistical relationship in that study, not a rule for predicting one person's score or extrapolating to children.
To interpret an age-group chart, look for the named study, sample size, age bands, cue type, response method and hardware correction. Without these details, a decade-by-decade table can appear more precise than the evidence supports. This site does not currently collect age-matched visitor results.
If you want a personal benchmark, keep the same test mode and device and compare several sessions. Your age alone does not supply a fair comparison for a changed phone, screen or input method.
Is your reaction time good? Read the full set
A lower time means a faster recorded response in the same task. The numbers below translate milliseconds into familiar time intervals; they are not population percentiles or profession-level thresholds.
| Score | Seconds | Useful next check |
|---|---|---|
| 150 ms | 0.15 s | Can you repeat it across a full set without guessing the cue? |
| 200 ms | 0.20 s | Compare your average and median, not just your best attempt. |
| 250 ms | 0.25 s | Use a second complete set on the same setup as a comparison. |
| 300 ms | 0.30 s | Check for a distracted attempt or a changed input method. |
Worked example: attempts of 200, 210, 220, 230 and 400 ms have an average of 252 ms, a median of 220 ms and a best of 200 ms. The slow attempt raises the average. Keep it in the valid set rather than removing it because it looks inconvenient; the median helps explain the difference.
Visual, audio and choice reaction time measure different tasks
- Simple visual: detect one visual cue and make one response.
- Simple audio: detect a sound and respond. The browser's audio output path adds different delays from a display.
- Choice reaction: identify a cue and select among different responses. That adds a decision to detection and movement.
- Aim: locate and click a target. Pointer travel and accuracy contribute to the time.
- Color mode: respond only to the target cue. Withholding a response to other cues is a selective-response task.
Keep different modes separate in your history. An aim time should not be judged against a simple visual mean. A phone tap and a mouse click also have different movements and input paths.
How to establish your average reaction time
- Choose one mode and input method, and keep the browser in the foreground.
- Use a short practice set to learn the instructions, then record five valid attempts.
- Save the average, median and best, plus the device and input details. The main reaction speed test supports CSV export.
- Repeat a full set under the same conditions. Keep false starts separate from valid responses.
- Look for a repeatable change across sessions. A single faster best score is weaker evidence than a consistent change in the full sets.

Average reaction time questions
What is the average human reaction time?
There is no single average for every task and device. Published visual-test results provide context, but a mouse click, a sound response and a choice between actions measure different things. Use the study table above and compare repeated sessions on the same setup.
What is a good reaction time for my age?
Age-group averages describe samples, not a pass mark for an individual. Keep the task and device the same, record several complete sets and compare your own average and median. This site does not have an age-matched visitor dataset for ranking you.
What is the average reaction time for a 14 year old?
The adult study summarized here does not include 14 year olds, so its age table cannot supply a reliable average for that age. A meaningful comparison needs research using the same task and an appropriate adolescent sample. Compare your own repeated sessions on the same setup.
Is this a national average reaction time chart?
No. The table reports selected age groups from one named adult study. It is not a nationally representative survey or a distribution of this site's visitors, and it cannot give a population percentile for your browser score.
Is 200 ms a good reaction time?
200 ms is faster than the recorded means in the study table, but a browser result is not directly comparable to a calibrated laboratory result. Check your average and median across five valid attempts, then repeat the set on the same setup.
Is a 150 ms reaction time possible?
A browser can record 150 ms, but that number alone cannot distinguish a response to the cue from anticipation or device effects. Repeat the test with randomized waits and compare full sets rather than one best attempt.
What is the average reaction time for gamers?
There is no verified universal average for all gamers on this site. Games involve different cues, choices and movements, and player setups vary. Compare results from the same task and hardware before drawing conclusions about gaming performance.
Does a lower browser score mean my reflexes improved?
It may reflect a faster response, familiarity with the task, better attention or a different input/display delay. Keep the device and test mode fixed, and look for a repeatable change across complete sessions.
