Keychron M3 4K – Shape & Fit Overview
The Keychron M3 4K is a wireless ambidextrous gaming mouse weighing 79g with dimensions of 125.2 × 68.2 × 40.6mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.
For hand sizing, the M3 4K fits best for hands measuring 179–228mm in length and 80–97mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 79g, the M3 4K is classified as lightweight. Mice in the 60–80g lightweight range offer an excellent balance between low fatigue and build stability.
The PixArt PAW3395 sensor is a flagship-class optical sensor with flawless 1:1 tracking, zero smoothing, and zero acceleration — the gold standard for competitive play.
