Typing Test FAQ

How is WPM calculated here? ▾

We count correct characters only, divide by 5, then divide by active time (pauses excluded). Mistyped characters don’t inflate WPM.

How is accuracy measured? Does backspace matter? ▾

Accuracy is correct ÷ total typed. Errors lower accuracy until corrected. Using backspace to fix a mistake improves the final accuracy, but the error is still tracked in your heat map.

What are the “Consistency” and “KPS” stats? ▾

KPS is keypresses per second—your pacing. Consistency rewards steady rhythm across the test (fewer spikes/drops). Aim for smooth KPS to raise consistency.

How does the error heat map work? ▾

Each key’s error rate is tallied as you type. Brackets, quotes, slashes, and numbers are tracked too. Darker cells = more errors—use them to pick targets for practice.

Can I pause the test? ▾

Yes. Use Ctrl+P. We also auto-pause when the tab isn’t visible. Paused time is excluded from scoring.

Why do I see a Caps Lock warning? ▾

A small badge appears when Caps Lock is on to prevent accidental ALL-CAPS errors that hurt accuracy.

How do I use Custom text? Why can’t I paste into the typing box? ▾

Add your content in Custom mode (up to ~5000 characters). Pasting is disabled in the live typing field to keep scores fair—type it in, don’t paste through it.

What’s the difference between Common, Quotes, Code, and Numbers? ▾

Common uses everyday words, Quotes adds punctuation variety, Code focuses on braces, brackets, symbols, and Numbers emphasizes digits and separators.

Do I need an account? Where is my data stored? ▾

No account required. The test runs in your browser and keeps things lightweight and private.

Does it work on phones? ▾

Yes. The layout adapts for smaller screens. Some desktop visuals (like the full keyboard activity view) are simplified on mobile for clarity.
