Microsoft IntelliMouse Optical 1.1a – Shape & Fit Overview

The Microsoft IntelliMouse Optical 1.1a is a wired ambidextrous gaming mouse weighing 147g with dimensions of 126 × 68.1 × 39.3mm. Its middle-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the IntelliMouse Optical 1.1a fits best for hands measuring 180229mm 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 147g, the IntelliMouse Optical 1.1a is classified as full-weight. Heavier mice over 100g deliver a premium, planted feel that some players prefer for precise, deliberate aiming.

The Microsoft Optical sensor provides solid tracking performance for its price point. Maximum DPI is 400. Polling rate: 125Hz.
