Typing Latency Test — Where the typing test measures throughput (words per minute), this test measures rhythm: how many milliseconds pass between one keystroke and the next, how steady that rhythm is, and where your longest hesitations happen. Two typists with the same WPM can have very different keystroke timing — and rhythm is what matters for fast-paced chat, competitive games with text input, and input-latency tuning.
Keystroke timings are analyzed locally in your browser. What you type and when are never sent anywhere.

Typing Latency Testとは？
Where the typing test measures throughput (words per minute), this test measures rhythm: how many milliseconds pass between one keystroke and the next, how steady that rhythm is, and where your longest hesitations happen. Two typists with the same WPM can have very different keystroke timing — and rhythm is what matters for fast-paced chat, competitive games with text input, and input-latency tuning.
Type a short literary passage; every character-producing keystroke is timestamped locally. When the passage is complete you get the median gap, the average, the standard deviation (steadiness), and the longest pause.
A lower standard deviation matters as much as a lower median: a steady 180 ms rhythm feels far more controlled than an erratic mix of 40 ms bursts and 600 ms stalls, even at the same average.
使い方
-
Read the passage
A short quote appears above the input.
-
Type it at your natural pace
Do not rush — this test is about rhythm, not speed.
-
Get the breakdown
The analysis runs automatically when the passage is complete.
使用例
Reading your numbers
What the stats say about your typing.
結果： Median under 200 ms with a small standard deviation means fluid, confident typing. A long "longest pause" usually marks one hard word, not slow fingers.
