Keyboard Tray Supplies
Woodworking Planshow to Woodworking Plans for In order to tackle a DIY drawer slide tray you’ll need a few things on hand.
Before starting your build you’ll want to have the following on hand (I’ve included a few helpful links to products you might like):
Steps to Build a DIY Keyboard Tray
These are the basic steps to build a DIY keyboard tray:
- Determining the size of the tray
- Building the keyboard tray and mounting brackets
- Finishing the keyboard tray
- Installation tips and tricks
Step #1 - Determining the size of the tray
This first step is the most critical and will require a few precise measurements. So, if you’re not comfortable with fractions or millimeters you might want to check into a pre-manufactured tray.
Woodworking Planshow to Woodworking Plans for Determining the tray width under an open area desk
If your tray won’t mount between two vertical surfaces you’ll have the freedom of picking the width of keyboard tray you’d like. And while most purchased trays are between 21-25″ (50-65cm) you can best determine your width by laying out your keyboard and mouse on a flat surface.
After a bit of playing around and finding the maximum space you’ll need for moving the mouse (without picking it up!) you’ll have the width down.
Lastly, if you have under 25″ of space you might need to consider a factory tray with extending mouse pad*.
Measuring keyboard tray width when mounting between two vertical sides
While it will be easier to install, if your keyboard tray fits between two vertical spaces you’ll need to accommodate side mount drawer slides in your measurements.
What’s special about the drawer the 1 last update 2020/07/08 slide width?What’s special about the drawer slide width?
Well, almost all side mount drawer slides require a 1/2″ on each side for clearance. So if your opening is 24-1/2″ you’ll need to plan the finished width of your DIY keyboard tray at 23-1/2″.
Determine keyboard tray depth
At this point you should have your trays drawer slides selected. The depth of the keyboard tray should allow the full keyboard to be accessible when the slides are extended.
So what should you watch out for? A few things:
- For partial extension slides you’ll want to make sure they extend enough for all areas of the keyboard to be accessed.
- And with full extension slides deduct the depth the drawer slides be mounted behind the front of the desk from the slide length.
Lastly, the minimum depth of the keyboard tray should then be the overall depth of the keyboard PLUS 3″ for a padded wrist wrest (if it’s not built into the keyboard).
Step #2 - Building the keyboard tray
At the simplest, this step can involve cutting your plywood to width and length, sanding the edges and proceeding.
But there are a few ways to make the finished tray look better:
- For slide-out shelves a great way to conceal the plywood edge is with either stick-on edge banding* or by wrapping the plywood with a 1/2″ x 1″ (or thicker) piece of solid wood
- Then, use a router to round-over the wood edge for comfort
Woodworking Planshow to Woodworking Plans for If your tools don’t include a table saw, then edge banding is the way to go.
Step #3 - Applying finish to the tray
With any keyboard tray you’ll want to apply a finish to avoid the wood from soaking up oils from your hands. And to make the mouse move smoother over the surface.
My recommendation? Check out one of the finishes in our guide to clear wood finishes (I prefer General Finishes wipe on). You’ll have a smooth finish in hours with no messy brushes.
Step #4 - Installing the tray

Not sure how thick the top is? One trick is pulling the desk away from the wall to review the top edge.
And unless it’s an extremely low quality desk the top should be at least 1/2″ thick.
Side mount drawer slide installation
If you’ll be mounting the keyboard tray between two vertical surfaces you’ll be using side mount slides. While easier, in my opinion, to install than a top mount slide you’ll want to consider:
- Find the height of the top of the keyboard tray in relation to the top of the drawer slide.
- If handy, a drawer slide jig will be worth it’s cost (but not just for this type of drawer alone) if you are doing other remodeling projects
- Mark the height of the slides and attach using supplied screws
Top mount drawer slide installation
If it’s possible, the easiest way to install a DIY keyboard tray to an existing surface is by turning it upside down. Literally.
By doing this you’ll have gravity working with you and not against you as you install and screw the slides to the underneath of the desk or table.
If that’s not an option, here’s a few tricks:
- Fully assemble the keyboard tray and slides.
- Then lift the assembly under the surface and mark with pencil or masking tape the location of the top mounts
- Make any height adjustments as you do this step (as top mounts are adjustable)
- Then disassemble the tray and install the slides
