Body shapeiDescribes shell symmetry, not the intended hand. Symmetrical with side buttons on one side differs from an asymmetric right-handed body. Ambidextrous means a symmetrical body with side buttons on both sides.

Asymmetric, right-handed5Reviewmacworld.com/article/2928916/logitech-mx-master-4-mouse-review.htmlRead 6 October 2026Review dated 4 October 2025 notes right-handed only, with no left-handed model. Maker gallery images show the asymmetric body with a left thumb rest.

Symmetrical body1Maker product pagelogitech.com/en-us/shop/p/m650-signature-wireless-mouse.910-006250Read 20 October 2026FAQ: the M550, M650 and M750 share the exact same shape. The M550 is ambidextrous and the M650 adds two side buttons. The body is stored as symmetrical with side buttons on one side. A dedicated M650 L Left exists with the side buttons on the right.

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 MX Master 4 for Business page labels the same body 50.8 mm Height and 128.2 mm Depth, so 128.15 mm is the front-to-rear length and 50.8 mm the height.

Logitech labels the front-to-rear length Height and the body height Depth, so the figures are mapped by size: length 108.2, width 61, height 38.8. The M550 has the same three figures, and the page states they share the exact same shape.

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

Mouse weight (claimed)iWireless mice include the battery. When the maker does not say whether a removable battery is in the weight, the published weight is stored and the source note says so.
