Logitech G703 Lightspeed – Shape & Fit Overview

The Logitech G703 Lightspeed is a wireless ergonomic gaming mouse weighing 107g with dimensions of 124 × 68 × 43mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the G703 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 107g, the G703 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.

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