Logitech MX Master 3 – Shape & Fit Overview

The Logitech MX Master 3 is a wireless ergonomic gaming mouse weighing 142g 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 3 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 142g, the MX Master 3 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. Maximum DPI is 4,000. Polling rate: 125Hz.

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