Shape

2 of 14 differ

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.

Symmetrical body1Maker product pagelogitech.com/en-us/shop/p/m550-signature-wireless-mouseRead 15 October 2026Page FAQ says the M550 lacks side thumb buttons and its shape is symmetrical and ambidextrous. Stored as symmetrical because it has no side buttons on either side.

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.

Sizing guide: small under 17.5 cm, medium 17.5 to 19.0 cm, large over 19.0 cm. The guide does not name the measured dimension, so it is read as hand length. Stored as an upper limit of 190 mm.

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.

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.
