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.

Length138Maximum width69.2Maximum height68.1mm(5.4 × 2.7 × 2.7 in)1Maker product pageprotoarc.com/products/em11-nl-vertical-mouseRead 15 October 2026Specs tab lists Height 68.1 mm, Width 69.2 mm and Depth 138 mm. The manual lists 138 x 69.2 x 68.1 mm. Stored as length 138, width 69.2 and height 68.1. Page image shows 5.43 in long, 2.72 in wide and 2.67 in high.

Length103.886Maximum width68.072Maximum height37.846mm(4.1 × 2.7 × 1.5 in)1Maker product pagetecknet.com/products/wireless-optical-mouseRead 21 October 2026Feature image Compact & Portable and the page text: 4.09 x 2.68 x 1.49 inches (length, width, height), converted exactly. The page also prints a Size line of 2.68 x 1.52 x 4.21 inches, and the Amazon listing repeats it, so the maker figures disagree by 0.12 inch in length and 0.03 inch in height. The length and height from the dimension drawing are stored. The store product feed text read on 2026-10-21 prints 4.09 x 1.88 x 1.49 inches, which disagrees on the width. A 1.88 inch body does not match the product photos, the Amazon listing or the feature image, so 2.68 inches is kept.

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.
