Keychron M3 Mini 4K – Shape & Fit Overview

The Keychron M3 Mini 4K is a wireless ambidextrous gaming mouse weighing 55g with dimensions of 119.9 × 65.3 × 38.9mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the M3 Mini 4K fits best for hands measuring 171218mm in length and 7793mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.

At 55g, the M3 Mini 4K is classified as ultralight. Ultralight mice under 60g are a favorite for FPS players who prioritize fast flicks and reduced wrist fatigue during long sessions.

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.

Dimensions listed are from manufacturer specifications. Minor variances may exist between production batches.
