3 minute typing test

Three minutes rewards clean typing

Over three minutes most people type somewhere between 100 and 150 real words. That's enough text that mistakes stop being rare events. A typist who never fixes errors and a typist who fixes every one can post the same raw speed and very different net scores.

The scoring explains why. Net WPM only credits words you typed exactly right, plus their trailing space, divided by five and by three. A word with one wrong letter that you leave in place contributes nothing. Raw WPM, shown beside it, counts every character you typed, right or wrong. If the two are far apart, you've found where your points went.

Should you fix a typo or keep going?

On this test, fixing a nearby typo is usually the better deal, and you can work out why.

Take someone typing at 45 WPM. That's 225 characters a minute, or about 3.75 a second. A one-letter slip caught straight away costs two extra keystrokes, backspace and the right key, which is around half a second. Leaving the word wrong costs the whole word: on our English list an average word plus its space is about six characters, which takes about 1.6 seconds to type. So the quick fix is worth roughly three times what it costs.

The maths turns against you when you notice the error late. Backspacing through four or five characters, retyping them and getting your rhythm back can cost as much as the word itself. A sensible rule for a three-minute test: fix it if you catch it inside the word, let it go if you're already two words on.

One thing to know about accuracy: the wrong key you pressed stays in your accuracy figure even after you correct it. Backspace itself isn't counted. So fixing errors improves net WPM but not accuracy, and the only way to raise accuracy is to press fewer wrong keys in the first place. There's more on this in what typing accuracy really measures.

What each wrong word costs

Here is the arithmetic for 180 seconds. Standard words are five characters, so characters typed equal WPM times 15.

Each uncorrected word removes roughly 0.4 WPM over three minutes. That sounds small until you count them: fifteen of them take six points off a 50 WPM typist, which takes you from just under the study average quoted below to well under it.

Using the results screen after three minutes

Start with the per-word list. Words you left wrong are marked, and each word shows its burst speed. If the same short, familiar words keep failing, the cause is usually rhythm: one hand getting ahead of the other and swapping two letters.

Then check the most-missed keys. A three-minute sample gives each common key enough repetitions for the pattern to be meaningful, which is less true of a 30-second run. Take the top two or three into practice mode and drill them for a few minutes.

Finally compare mistake percentage across sessions. It's 100 minus accuracy, and a falling mistake rate at the same raw speed is real progress even when the headline number barely moves.

What a good 3-minute score is

A 2018 study by Aalto University and the University of Cambridge, built on keystrokes from roughly 168,000 volunteers, found an average of 52 WPM, with most people between 30 and 60. Expect your three-minute net figure to sit a little below your one-minute figure; short tests tend to read higher. Above 60 net at three minutes, with accuracy in the high 90s, is fast by any everyday standard.
