How to Test Your Keyboard Online

Press any key on your physical keyboard to test its input response instantly. The virtual keyboard highlights each key as it registers, allowing you to verify key actuation, detect stuck keys, and identify hardware responsiveness issues without installing software.

Supported Keyboard Form Factors

• 100% Full Size (~104 keys): Includes standard alphanumeric keys, navigation cluster, arrow keys, and a dedicated numeric keypad (numpad).
• 80% Tenkeyless / TKL (~87 keys): Features standard layout without the numeric keypad for a more compact footprint.
• 75% Compact (~84 keys): Retains function keys and dedicated arrow keys in a tightly packed layout.
• 65% Compact (~68 keys): Removes the function row while keeping arrow keys and key navigation controls.
• 60% Mini (~61 keys): Ultra-compact layout providing core typing keys; function actions are accessible via key combinations.

Common Keyboard Issues You Can Detect

• Unresponsive Keys: Keys that fail to highlight indicate a broken switch, faulty PCB trace, or dirty contact point.
• Key Chattering (Double Typing): Keys registering multiple inputs on a single stroke.
• Ghosting & N-Key Rollover: Press multiple keys simultaneously to verify how many inputs your keyboard can register at once.

Frequently Asked Questions

Q: Why is a specific key not highlighting on the tester?
If a key fails to light up, it usually indicates a faulty mechanical switch, dust/debris under the keycap, a failed PCB socket, or a loose connector cable.

Q: What is key ghosting and how do I test it?
Ghosting occurs when certain key combinations fail to register simultaneously due to hardware wiring limits. Press multiple keys at once (e.g., W, A, S, and Space) to verify your keyboard's N-key rollover capability.
