Logitech G903 Lightspeed – Shape & Fit Overview
The Logitech G903 Lightspeed is a 2019 wireless ambidextrous gaming mouse weighing 110g with dimensions of 130 × 67 × 40mm. Its middle-mounted hump makes it particularly well-suited for palm and claw grip styles.
For hand sizing, the G903 Lightspeed fits best for hands measuring 186–236mm in length and 79–96mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 110g, the G903 Lightspeed is classified as full-weight. Heavier mice over 100g deliver a premium, planted feel that some players prefer for precise, deliberate aiming.
The Logitech HERO 25K sensor is a flagship-class optical sensor with flawless 1:1 tracking, zero smoothing, and zero acceleration — the gold standard for competitive play. Maximum DPI is 25,600. Polling rate: 1000Hz.
