Logitech MX Master 3S – Shape & Fit Overview

The Logitech MX Master 3S is a wireless ergonomic gaming mouse weighing 141g with dimensions of 124.9 × 84.3 × 51mm. Its rear-mounted hump makes it particularly well-suited for players who prefer a flatter profile.

For hand sizing, the MX Master 3S fits best for hands measuring 178227mm in length and 99120mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.

At 141g, the MX Master 3S is classified as full-weight. Heavier mice over 100g deliver a premium, planted feel that some players prefer for precise, deliberate aiming.

The Logitech Darkfield sensor is a reliable mid-range sensor that performs well for competitive gaming without top-shelf pricing.

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