"What's a good reaction time?" is the most-asked question about reflexes — and almost every answer online ignores the biggest variable: the hardware you measured it on. Let's fix that.
The average simple visual reaction time is roughly 200–260 ms for a rested adult on ordinary hardware; practiced gamers and athletes often reach 150–200 ms, and auditory reaction times run a little faster in controlled tasks. These are orientation ranges, not lab norms — and the single biggest confound is the display, input, and audio path you measured on, which is why every reaction time test hub result here carries a ± confidence band.
Rough simple reaction-time ranges
Simple reaction time (one stimulus, one response - what PulsarMS measures) varies by age, attention, hardware, task design, and input method. Treat the ranges below as orientation, not diagnosis or lab-grade norms:
| Context | Visual median guide | Notes |
|---|---|---|
| Rested desktop user | ~200-260 ms | Common simple visual baseline on ordinary hardware |
| Practiced gamer or athlete | ~150-200 ms | Fast, but still setup-dependent |
| Phone or touch input | Often slower | Touch posture and device pipeline differ |
| Fatigued or distracted session | Often slower and less consistent | Watch the slow tail and false starts |
| Older adult sessions | Often slower on average | Age, health, task design, and hardware all matter |
Auditory reaction time is often faster than visual reaction time in controlled simple tasks, but the gap is not a universal constant. Output device latency can erase the advantage. Run both our visual and audio tests on the same setup, then compare visual median against the audio average from its 10 cues.
Reaction-time sessions often have a slow tail: a few late responses caused by attention lapses or distraction. That's why we report your median, which is more robust than a small sample mean.
The variable nobody controls for: your screen
Here's the uncomfortable truth. A reaction-time number measured on a 60 Hz laptop and one measured on a 240 Hz gaming monitor are not cleanly comparable. Display refresh, panel behavior, input device, browser mode, and posture all change the practical response loop before your training does anything.
That's why we:
- record your display refresh rate with every visual result,
- show a ± confidence band that reflects your hardware,
- and label audio results as relative unless calibrated.
So what's your real number?
The honest answer: your browser-observed response is only as meaningful as the setup and confidence band around it. The consistency of your results matters as much as the median. A player with a steady median and tight spread has a more repeatable baseline than one bouncing between a fast guess and several slow lapses.

Frequently asked questions
+What is a good reaction time?
The average simple visual reaction time is roughly 200–260 ms for a rested adult on ordinary hardware. Practiced gamers and athletes often reach 150–200 ms, and auditory reaction times run a little faster in controlled tasks. Treat these as orientation ranges, not lab norms — the hardware you measure on shifts the number.
+What is the average reaction time by age?
Older adult sessions are often slower on average, but age is only one variable alongside attention, health, task design, input method, and hardware. A rested desktop baseline of ~200–260 ms is the useful reference point; phone or touch input often reads slower because the posture and device pipeline differ.
+Does my monitor change my reaction time score?
Yes — a number measured on a 60 Hz laptop and one measured on a 240 Hz gaming monitor are not cleanly comparable. Display refresh, panel behavior, input device, browser mode, and posture all change the response loop, which is why every result records the refresh rate and carries a ± confidence band.
+Why is my reaction time inconsistent between sessions?
Sessions often have a slow tail — a few late responses from attention lapses. That is why the median is reported rather than the mean, and why consistency matters as much as speed: a steady median with tight spread is a more repeatable baseline than one fast guess among slow lapses.
