2 of 5 differ

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.

Length109Maximum width61Maximum height35.56mm(4.3 × 2.4 × 1.4 in)1Maker product pageamazon.com/dp/B005EJH6RWRead 14 October 2026Bullet: Product Dimensions 4.3 x 2.4 x 1.4 inches (LxWxH) with 4.9-foot cable. A listing feature image gives 4.3 in / 10.9 cm length and 2.4 in / 6.1 cm width. Length and width store the centimetre figures. Height is 1.4 in converted exactly. All are rounded maker figures. The cable is not part of the body size. Amazon UK gives 10.9 x 6.1 x 3.4 cm in its bullet and 4.3 x 2.4 x 1.25 in in its description, so the maker's height differs by listing (34 mm and 31.75 mm against 35.56 mm). The US figure stays because it is the one on the listing that names the cable.2Owner's manualm.media-amazon.com/images/I/C1RapdFAgKL.pdfRead 14 October 2026

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. Wired mice exclude the cable. Source notes identify installed skates, colour, approximation, tolerance or a published bound.

80g(2.8 oz)1Maker product pageamazon.com/dp/B005EJH6RWRead 14 October 2026Item details: Item Weight 0.08 kg, published rounded to 0.01 kg. The listing does not say whether the cable is included. Some resellers copy 2.89 oz (about 82 g) and qualescegliere.it lists 76.55 g without a method, so 80 g is the published figure only.

107.9g(3.8 oz)1Maker product pagelogitech.com/en-us/shop/p/signature-comfort-plus-m850lRead 14 October 2026Page lists 107.9 g with battery and 82.9 g without battery. The Signature Comfort Plus M850 L for Business (910-007703) is listed at 102.9 g with battery, so the Business version is a different configuration.
