Age vs Reaction Time Chart | The Full Curve from 10 to 80+

Reaction time follows a well-documented U-curve: sharpens through the late teens, peaks around 24, then slows roughly 0.5 ms per year. See where you sit on the curve in 90 seconds.

The Curve, Decade by Decade

| Age | Avg reaction (ms) | |---|---| | 10–15 | 285 | | 16–24 | 245 (peak) | | 25–34 | 255 | | 35–44 | 270 | | 45–54 | 290 | | 55–64 | 315 | | 65–74 | 340 | | 75+ | 370 |

You Can Bend the Curve

Daily 90-second precision training shifts age-banded means by 20–40 ms regardless of starting age. The curve is real but not destiny.

FAQ

When does reaction time peak?

Roughly age 24, then declines slowly with consistent training able to offset most of it.

Is the decline reversible?

Partially — training measurably offsets age-related slowing.

Is the test free?

Yes, fully free, no signup.
