Mionix Castor – Shape & Fit Overview

The Mionix Castor is a wired ergonomic gaming mouse weighing 94g with dimensions of 122.5 × 70.4 × 40.2mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the Castor fits best for hands measuring 175223mm in length and 83101mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.

At 94g, the Castor 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 PixArt PMW3310 sensor is a reliable mid-range sensor that performs well for competitive gaming without top-shelf pricing. Maximum DPI is 5,000. Polling rate: 1000Hz.

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