Mouse body dimensionsiLength from front to rear, width at the widest body point, and maximum height. Cable and receiver are excluded. Approximate maker figures are qualified in source notes. Logitech pages often label the front-to-rear length Height and the body height Depth, so map the figures by size.

The manual lists 4.92 x 2.5 x 1.55 in. Stored as length 125 and height 39.3. The 63.4 mm width is left out. The maker's top-view drawing shows a body wider than half its length once the thumb lobe is included, so the figure appears to exclude the lobe. No source says what the width covers. A reviewer of the EM01 lists the same 63 x 125 x 39 mm.

Grip widthiBody width where the thumb and opposite grip finger sit. This differs from maximum body width.
