Tray dimensions affect comfort, keyboard compatibility, and available space for mousing. The best tray size accommodates a standard keyboard and leaves room for wrist support and mouse use. Most trays in this category are around 21" wide and 10.5" deep, as found in the Classic Lever Arm with Keyboard Tray and Economy Arm with Keyboard Tray. Larger trays support more extensive input devices or additional accessories, while more compact trays like those on the Encore Arm with Keyboard Clamp Tray focus on minimalism and clamp-style attachment. This range allows users to choose the size that best fits their equipment and workspace.
