How to Make a Wooden Desk with a Slide-Out Keyboard Tray

Building your own desk with a slide-out keyboard tray can be an incredibly rewarding project. Not only will you have a custom piece of furniture that fits your space and style perfectly, but you’ll also save money while building a functional and ergonomic workstation. In this guide, we’ll walk you through the steps to create a wooden desk with a slide-out keyboard tray. You don’t need to be a professional woodworker, but having some basic tools and woodworking knowledge will help ensure a smooth process.

Materials You Will Need:

  • Wood (for the desk top and frame): Choose a hardwood like oak, maple, or plywood for a solid, durable surface.
  • Slide-out keyboard tray mechanism: Available at most hardware stores, these sliding tracks will allow the keyboard tray to extend and retract smoothly.
  • Wood screws: For assembling the frame.
  • Wood glue: To secure joints.
  • Wood filler: To fill any gaps or screw holes.
  • Sandpaper: For finishing the surface.
  • Stain or paint: For finishing the wood to match your décor.

Tools You’ll Need:

  • Measuring tape: For accurate measurements.
  • Saw (circular or table saw): For cutting the wood to size.
  • Drill: For drilling holes and driving screws.
  • Screwdriver: For tightening screws.
  • Clamps: For holding pieces together while gluing.
  • Miter saw (optional): For cutting angles, if desired.

Step-by-Step Instructions:

Step 1: Planning and Measurements
  1. Desk Dimensions: Start by deciding on the overall size of your desk. A typical desk top is around 48 inches wide by 24-30 inches deep. Adjust these dimensions according to your needs and space constraints.

  2. Keyboard Tray Size: The slide-out keyboard tray should be wide enough to hold your keyboard and mouse comfortably. A standard size is around 24 inches wide and 12-16 inches deep, but measure your keyboard and accessories to ensure a good fit.

  3. Desk Height: The standard desk height is around 28 to 30 inches. The keyboard tray should be positioned at a comfortable height when pulled out, typically 2-4 inches below the desk surface.

Step 2: Cutting the Wood
  1. Cut the Desk Top: Using your saw, cut the wood for the desk top to the desired dimensions. If you’re using plywood, you may want to edge the plywood with solid wood strips for a more polished look.

  2. Cut the Desk Frame: Cut four pieces of wood for the legs (typically 28-30 inches long) and four pieces for the side supports (depending on the design, you may want a rectangular frame or simple side legs). The side supports should be the same length as the width of the desk.

  3. Cut the Keyboard Tray: Cut a piece of wood for the slide-out tray to the measurements you’ve chosen, making sure it fits the sliding mechanism you’ve purchased.

Step 3: Assembling the Frame
  1. Attach the Legs to the Side Supports: Begin by attaching the four legs to the side supports. Use wood screws and wood glue for a strong, durable joint. Make sure the frame is square by measuring the diagonals of the frame to ensure they are equal.

  2. Attach the Desk Top to the Frame: Once the legs and supports are in place, attach the desk top using wood screws or metal brackets. Be sure to leave a small gap between the edge of the desk top and the frame to allow for the slide-out keyboard tray.

Step 4: Installing the Slide-Out Keyboard Tray
  1. Measure and Mark the Placement: Mark the area where you want to install the keyboard tray beneath the desk. The tray should be positioned low enough to accommodate your legs comfortably while seated but still accessible when extended.

  2. Attach the Sliding Mechanism: Attach the sliding tracks to the underside of the desk, following the manufacturer’s instructions. Most sliding mechanisms require screws and may have adjustable features for different tray depths. Ensure the tracks are installed evenly on both sides.

  3. Attach the Keyboard Tray: Once the tracks are securely installed, slide the keyboard tray into the tracks. Make sure it slides in and out smoothly. If it feels tight or catches, check the alignment of the tracks and adjust as needed.

Step 5: Finishing Touches
  1. Sand the Desk: Use sandpaper to smooth out any rough edges and surfaces. Start with a coarse grit and work your way up to a finer grit for a smooth finish.

  2. Fill Any Holes: Use wood filler to cover any screw holes or gaps in the wood. Once the filler is dry, sand it smooth.

  3. Stain or Paint the Desk: Apply your chosen stain or paint to the desk. Staining can bring out the natural beauty of the wood, while painting offers a more uniform, modern look. Be sure to apply a finish or clear coat for protection.

  4. Final Assembly: If your desk includes any additional features like drawers or shelves, now is the time to assemble and install them. Double-check the keyboard tray’s movement and ensure it’s functioning as intended.

Step 6: Enjoy Your New Desk

Once everything is assembled, sanded, and finished, your new desk with a slide-out keyboard tray is ready to use! Enjoy the comfort and convenience of having an ergonomic workspace that you crafted with your own hands.


This project is a great way to add a personal touch to your home office while creating a functional and stylish piece of furniture. The slide-out keyboard tray will not only keep your desk more organized but also provide an ergonomic solution for your typing needs.
