Logitech G603 Lightspeed – Shape & Fit Overview

The Logitech G603 Lightspeed is a wireless ergonomic gaming mouse weighing 89g with dimensions of 124 × 68 × 43mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the G603 Lightspeed fits best for hands measuring 177225mm in length and 8097mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.

At 89g, the G603 Lightspeed is classified as mid-weight. Mid-weight mice in the 80–100g range feel substantial and controlled, a popular choice for players who dislike very light designs.

The Logitech HERO 12K sensor is a high-performance optical sensor delivering accurate, consistent tracking suitable for the most demanding competitive use. Maximum DPI is 12,000. Polling rate: 1000Hz.

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