Office & Productivity · Under-Desk Keyboard Trays
What size keyboard tray do I need for a full keyboard and mouse?
Reviewer consensus
Most full-size keyboards plus a mouse fit comfortably on a platform around 26 to 28 inches wide. The widest options here run 27 inches of usable platform, while compact models around 25 inches suit tenkeyless or split setups where the mouse sits elsewhere. Verified reviewers repeatedly warn to measure your keyboard and desk underside clearance before buying.
