Typing Test

How to use

1. Choose a preset passage, or type your own.
2. Start typing; the timer begins on the first keystroke.
3. Watch the live speed and accuracy, with typos highlighted.
4. Read the final characters-per-minute and accuracy.

How it works

How characters-per-minute is computed

Speed = characters typed / minutes elapsed, with each Chinese character counting as one; accuracy = matching positions / characters typed. Timing accrues from the first character until the whole text is finished, and pauses mid-way don't stop the clock.

How mistakes are handled

Mistakes are marked in red and can be corrected with backspace anytime; you can also keep typing over errors, counted at settlement. Extra characters beyond the text aren't counted; to retest, press "restart" to zero and begin again.

What speed counts as fast

Pinyin typing commonly runs 40-60 characters per minute, over 80 counts as skilled, and double-pinyin or Wubi experts reach 120+; 40 WPM English (about 200 characters per minute) is the office pass line. Accuracy matters more than average — below 95%, aim for precision before speed.

How to practice for the fastest gains

A fixed 10 minutes daily beats a two-hour weekend binge; first slow down and raise accuracy above 98%, and speed rises on its own. The numbers-and-symbols section specifically trains the numpad and symbols, a weak spot pure chat typing can't fix.

Code example

// compare as code point arrays: indexing a string splits surrogate pairs (emoji)
function stats(target, typed, seconds) {
  const t = [...target];
  const y = [...typed];
  let correct = 0;
  for (let i = 0; i < y.length; i++) { if (y[i] === t[i]) { correct++; } }
  const acc = (correct / Math.min(y.length, t.length)) * 100;   // denominator = shorter side
  const wpm = (typed.trim().split(/\s+/).length) / (seconds / 60);
  return {
    wpm: Math.round(wpm),
    acc: acc.toFixed(1),
    progress: Math.min(100, Math.round((y.length / t.length) * 100)),
    done: y.length >= t.length && typed === target,
  };
}

import time

target = 'the quick brown fox jumps over the lazy dog'
input('press Enter, then type the sentence:')
start = time.monotonic()
typed = input()
elapsed = time.monotonic() - start

correct = sum(1 for a, b in zip(target, typed) if a == b)
print(f'{elapsed:.1f}s  accuracy {correct / len(target) * 100:.1f}%')
print(f'{len(typed.split()) / (elapsed / 60):.0f} wpm')
