Typing Trainer

Why touch typing is worth learning properly

Touch typing means typing without looking at the keyboard, using muscle memory so each finger owns a fixed set of keys. The payoff is large: a hunt-and-peck typist manages perhaps 25–30 words per minute, while a trained touch typist comfortably reaches 60–80, with eyes on the screen the whole time. This trainer builds that skill the way it is actually learned — one zone of the keyboard at a time, with live feedback on every keystroke — rather than throwing full paragraphs at you before your fingers know where the keys are.

The five-lesson progression

The lessons are deliberately ordered to match how the keyboard is structured around the home row, the resting position where your fingers begin and return:

Each lesson holds several practice texts; the Next Text button cycles through them so you are not just memorising one line. Work them in order — fingers that own the home row first will learn the other rows far faster.

How WPM and accuracy are measured

The timer starts on your first keystroke, not when the page loads, so thinking time before you begin is never counted against you. Words per minute uses the universal convention:

WPM = (characters typed ÷ 5) ÷ minutes elapsed

The division by 5 is the standard definition of a "word" — five characters, including the space — which is why "WPM" is comparable across any typing test you will ever take. Accuracy is tracked separately:

Accuracy = (correct characters ÷ total characters typed) × 100

As you type, each character is compared to the target: correct letters turn green, wrong ones turn red, and the next expected character is highlighted as a cursor. Errors are counted the moment they happen, and importantly that error tally persists even if you backspace and fix the mistake — so accuracy reflects how cleanly you typed, not just whether the final text matched.

A worked example

Suppose the home-row line is 60 characters long and you finish it in 30 seconds with 3 mistakes. That is 0.5 minutes elapsed, so WPM = (60 ÷ 5) ÷ 0.5 = 24 WPM. Accuracy = (60 − 3) ÷ 60 × 100 = 95%. If you slow down slightly and finish in 36 seconds but make zero mistakes, WPM drops to 20 but accuracy hits 100% — and on the next attempt your error-free muscle memory usually lets you speed back up past your original time. That trade is the whole point of deliberate practice.

Practice tips that actually move the numbers

• Prioritise accuracy over speed first. Every error you train in is a habit you later have to untrain. Aim for 98%+ before pushing for raw speed.
• Keep your eyes on the screen. The whole skill is not looking down. If you glance at the keys, you are practising the wrong thing.
• Return to the home row. After every reach to another row, your fingers should fall back to ASDF/JKL;. The little bumps on the F and J keys exist to find that position by feel.
• Restart to beat your best. The Restart button reloads the same text so you can attack a personal record on familiar material — a fast way to see measurable improvement.

Your progress is saved — and stays private

Your best WPM and accuracy for each lesson are stored in your browser's localStorage and shown as a "Best" badge, so you can watch yourself improve session after session. Because localStorage lives on your own device, this has two consequences worth knowing: your records persist after you close the tab, but they are tied to this browser on this machine — clearing site data or switching devices resets them. Nothing is uploaded; no account, no server, and no network connection is needed. The trainer runs entirely offline.
