Take the following measurements to measure how much space you have for a keyboard tray:
- Available depth underneath the work surface
- This measurement determines how long the keyboard track (retractable arm) needs to be.
- Make sure the surface is flat and unobstructed so the track can be installed.
- Standard preferred keyboard trays come with a 22 inches retractable track arm, which allows them to be installed under most work surfaces (standard work surface depth is 24 inches – 30 inches).
- 17-inch deep retractable arms are available for shallower work surfaces.
- Available width underneath the work surface
- This measurement determines how wide the keyboard tray platform needs to be. Make sure there are no drawers or other obstacles to prevent the platform from being pulled out from or pushed under the desk.
- Most standard keyboard tray platforms are 26 inches – 28 inches wide (to fit standard keyboards & mice). Other platform widths are available.
- To make sure your keyboard and mouse fit on the platform:
- Measure the dimensions of your computer keyboard and mouse so you know how large of a platform you need.
- Most keyboards are approx. 19 inches wide. Allow approx. 7 inches – 9 inches width for a mouse.
Refer to the Approved Equipment List for recommended keyboard trays. Compare your measurements to the ones listed and choose one that fits. The recommended bundles fit most workstations. All recommended keyboard trays on the UCSF Approved Equipment List are height- and tilt-adjustable.
