Typing Test Tips: How WPM and Accuracy Are Really Scored

Updated October 2026

A thirty-second typing run feels like a pure speed contest, but the number on the result card comes from a very specific counting rule, and that rule rewards some habits and quietly punishes others. Once you know exactly which keystrokes earn credit, you can stop guessing about whether to fix a typo, whether to rush the last word, or why a run that felt fast scored lower than a calm one. This guide walks through the scoring as the game actually computes it, turns it into a few simple numbers you can remember, and finishes with a practice routine built for phone keyboards.

What the clock measures, and when it starts

Nothing is timed while you look at the text. The run begins on the first character that reaches the input box, and from that moment it lasts exactly thirty seconds of real time, measured against the device clock rather than counted in animation frames. Locking the phone or switching apps does not freeze it, so treat every run as a single uninterrupted attempt.

The passage holds 260 words, which is far more than anyone can finish in half a minute, so you will never run out of text. Words are drawn at random from a list of 1,325 common lowercase English words, each between four and seven letters long, and the generator only refuses to put the same word twice in a row. Because the list leans slightly towards short words, the average word you will meet is a little over five letters. The passage area shows three lines; whenever you move to a new line, it scrolls so that your current word sits on the top line, where the keyboard cannot cover it.

The counting rule behind your score

Your result is built from one quantity: correct characters. When you press space, the word you typed is compared with the target letter by letter, position by position. Every position where your letter matches the target's letter earns one character. If the whole word is spelled exactly, the space after it earns one more. Those characters are then converted the way most typing tests do it: five characters count as one word, and the total is scaled to a per-minute rate.

Accuracy is calculated separately. The game adds up the length of everything you committed, plus one for each space, and divides the correct characters by that total. Two details matter here. First, characters you deleted with backspace before pressing space are never counted at all; only the final state of each word is judged. Second, extra letters typed past the end of a word count towards the total but can never be correct, so overshooting lowers accuracy without adding score.

When time runs out in the middle of a word, the letters you had already typed for it are still compared position by position and added, but that unfinished word never earns its space.

Turning the rule into numbers you can use

A word spelled perfectly is worth its letters plus a space. With an average length of about 5.4 letters, that is roughly 6.4 correct characters, or about 1.27 standard five-character words. Over a thirty-second run the result works out to roughly 2.5 times the number of words you finish perfectly. These are averages from the word list, so individual runs move a little with the luck of the draw, but the rule of thumb holds well:

• 20 clean words in thirty seconds is around 50 WPM.
• 30 clean words is around 76 WPM.
• 40 clean words is around 100 WPM.

That gives you a target you can feel. If you want to move from 60 to 75, you need about six more clean words per run, which is one extra word every five seconds. Thinking in words rather than in the abstract WPM figure makes progress easier to track.

Why a slipped letter can cost more than a wrong letter

Because the comparison is positional, the kind of mistake you make matters a great deal. A wrong letter in place of the right one costs only that position plus the space. Typing "hoise" for "house" still matches four of the five positions, so you keep four characters and lose two.

A missing or doubled letter is far worse, because every letter after it shifts out of line. Type "hose" for "house" and only the first two positions line up; the rest all mismatch, so you keep two characters and lose four. Type "hhouse" and you match only the opening letter. The earlier the slip, the more of the word it wipes out.

This leads to a practical rule: if you feel a skipped or doubled key near the start of a word, it is usually worth backspacing to that point and retyping, since the deleted keystrokes are not counted against you. A simple substituted letter near the end of a long word is often cheaper to leave alone and move on. The live colouring helps you tell which is which: letters you have right appear bright, letters that do not match turn red, and typing past the end of the word underlines it.

Typing well on a phone keyboard

The input box has autocorrect, automatic capitals and spell-check turned off, so the keyboard will not rescue or sabotage you. That honesty has a cost: habits that depend on autocorrect fixing sloppy taps will show up immediately as red letters.

• Hold the phone the same way every run. Thumb reach changes with grip, and a consistent grip is the fastest way to make key positions automatic.
• Hit the space bar deliberately. Space is the only thing that commits a word, and it earns a character itself on every clean word. A space that lands on a nearby letter instead glues two words together and ruins both. A double space, on the other hand, is harmless, because an empty word is simply skipped.
• Avoid gesture typing for this test. Swiping words may feel quick, but a guessed word that differs by one letter usually scores much lower than a tapped one, for the shifting reason above.
• Read one word ahead. While your thumbs finish the current word, let your eyes move to the next one. The pause between words is where most time disappears.

Mistakes that drag scores down

• Watching the live numbers. The figures at the top update ten times a second, and the WPM reading swings wildly in the first few seconds because it is divided by a tiny amount of elapsed time. Ignore it until the run ends.
• Panic fixing. Long strings of backspaces after a single error burn more time than the error costs. Fix shifted letters early in a word; leave small substitutions late in a word.
• Racing the final second. The unfinished word at the buzzer earns only its matching letters and no space, so a frantic last burst adds very little. A steady final word is worth the same as a rushed one.
• Overshooting short words. Four-letter words go by quickly and invite an extra stray letter. Each one lowers accuracy for nothing.

A ten-minute practice routine

1. Two warm-up runs at a calm pace. Aim for accuracy above 97 percent and ignore the speed figure entirely.
2. Three runs where you count clean words. Use the result card: it shows how many words you typed exactly out of how many you committed. Try to raise the exact count by one or two each time.
3. One run focused on the space bar. Say to yourself that each word ends with a deliberate space. Watch how accuracy changes.
4. Two runs at a slightly uncomfortable speed. Push until accuracy drops to around 92 percent, then note whether your WPM rose or fell. Most players find their best score sits just below the speed where shifted-letter slips start to appear.
5. Finish with one clean run at the pace that gave your best number, and save it if it beats your record.

Repeat this a few times across a week and the combination of fewer shifted letters and quicker transitions between words is usually worth more than any attempt to move your thumbs faster.
