Keyboard Tray: Ergonomic Buyer Guide
Why a Keyboard Tray?
A keyboard tray positions your keyboard at the correct height and angle for neutral wrist posture. Most desks are 29–30 inches tall—too high for ergonomic typing. A tray lowers the keyboard to elbow height (approximately 25–27 inches from the floor for most adults).
Key Features
Height Adjustment
Look for at least 6 inches of vertical adjustment range (e.g., 22–28 inches from the floor). This accommodates users of different heights and desk thicknesses. Clamp-on models fit desks up to 2.5 inches thick.
Tilt Adjustment
A negative tilt (keyboard angled slightly away from you, 5–15 degrees) keeps wrists in a neutral position. Avoid trays that only tilt forward (positive tilt)—this increases wrist extension and carpal tunnel risk.
Mouse Platform
An attached mouse platform keeps the mouse at the same height and angle as the keyboard. Look for reversible platforms (left or right side). Separate mouse platforms increase cost but offer flexibility.
Mounting Types
- Clamp-on: no drilling, removable, fits most desks. $40–$80
- Track-mount: slides under desk on a rail, more stable. $80–$150
- Articulating arm: full range of motion, premium option. $150–$250
Size Requirements
Measure your keyboard width (standard: 17 inches, full-size with numpad: 18–20 inches). The tray should be at least 2 inches wider than your keyboard. Depth should be 10–12 inches to accommodate keyboard plus wrist rest.
