The 30 second typing test is a popular middle ground between a quick sprint and a full minute. It is long enough to settle into a rhythm and short enough to keep your focus on every word, and it is a good choice when you want to try again and again.
Your WPM is your correct characters divided by five and by the minutes you typed. Here is what different speeds add up to in 30 seconds:
| Speed | Words in 30 seconds | Characters |
|---|---|---|
| 30 WPM | 15 words | 75 characters |
| 40 WPM | 20 words | 100 characters |
| 50 WPM | 25 words | 125 characters |
| 60 WPM | 30 words | 150 characters |
| 80 WPM | 40 words | 200 characters |
| 100 WPM | 50 words | 250 characters |
Expect a WPM a few percent higher than on a one minute test, usually 3% to 8%. Half a minute is not long enough for tiredness to matter, so the score is close to your best speed.
For comparison, most people type between 38 and 45 WPM, 45 to 65 is good, and 65 and up is fast. See the full table on the average typing speed page.
Pick your pace in the first five seconds and hold it. A steady speed that you can keep for the whole half minute scores higher than a fast start that you have to slow down from.
It gives a good estimate of your top speed. Employers and courses usually ask for a one minute score, so take a one minute test too when it matters.
At 40 WPM you type about 20 words, at 60 WPM about 30 words and at 80 WPM about 40 words.
Yes. It is short enough to repeat many times in a few minutes, which is how most people improve: a few quick tests, then look at where the mistakes came from.
