Measure the proper height for your keyboard. Stand up. Holding your hand and forearm straight with your elbows at a 90- to 120-degree angle in front of you, measure the height of your hand off the floor using a yardstick.
Measure the height of your current desk. Subtract the current desk height from the desired standing keyboard height. This is the height you want to build your keyboard stand.
Obtain a metal stacking shelf. The shelf's height adjusts in 1-inch increments by moving the locking mechanism on each leg to a higher or lower groove. Get a stacking shelf wide enough to fit your keyboard and mouse comfortably and deep enough to fit your monitor.
Place the metal shelving unit on your desk. Put the computer monitor, keyboard, mouse pad and mouse on the shelving unit.
Place a melamine shelf on top of the metal shelving unit if your monitor is not in a comfortable position. You can then add another small, metal shelving unit on top of the board or otherwise elevate the monitor.
Clear the area around the location for your new desk. Obtain melamine shelving deep enough to accommodate your monitor and keyboard.
Find the wall studs using a stud finder, an electronic device that emits sound waves that will bounce off the studs inside the wall. Screw the metal shelving brackets into studs on the wall using the drill. The tops of the brackets should be 2 inches lower than your optimum keyboard height.
Attach the melamine shelving to the brackets by screwing up from the bottom with the drill. Place the keyboard, monitor and mouse on the standing wall desk.
