Spacebar Counter
Measure your physical keyboard spacebar tapping rate with sub-millisecond hardware accuracy.
Tap Here or Press SPACE
Tap the spacebar with your thumb or finger as fast as you can.
Thumb vs Finger Technique
Competitive players often alternate between the thumb and index finger or vibrate the wrist for higher PPS scores.
Switch Travel Latency
Mechanical linear switches with shorter pre-travel distance (1.2mm - 1.5mm) provide the fastest spacebar reset times.
Real Hardware Timing
Measured via pure hardware keypress events with zero artificial software lag or browser throttling.
