DIY Fold-Down Wall Desk: Two Simple Plans, Sized for Knees and Screens

What you build and what it takes

There are two simple ways to build a desk that folds away:

Plan A is the DIY folding table with desk dimensions; the carpentry is the same as in the DIY wall-mounted folding table guide, so this page focuses on what changes for a desk. Plan B is a small cabinet build, close to a Murphy desk. Neither the bracket sellers nor Rockler give a build time.

Tools and material

• Plan A: two locking folding brackets, a board for the top, wood screws for the studs, short screws for the top
• Plan B: plywood for a shallow box, a full-length hinge for the front, a pair of flap stays sized for the front's weight, a catch if the stays have none
• Stud finder, tape measure, level, drill with bits, saw, sandpaper

Size it as a desk

Height. For seated work the top edge belongs at about 29 to 30 inches above the floor; the 2010 ADA Standards set 28 to 34 inches for work surfaces (902.3). The mounting height guide shows how to go from the top edge to the drill line.

Knee room. The ADA Standards treat the space between 9 and 27 inches above the floor as knee clearance and ask for at least 30 inches of width (306.3). On a bracket desk, the brackets sit under the top, so keep at least 30 inches clear between their inner edges. On 16-inch studs that rules out two neighboring studs; use every second stud or a ledger board.

Depth. A laptop works on a shallow top. A separate monitor needs more: OSHA asks for it directly in front of you and at least 20 inches away, so a narrow wall desk often pairs better with a wall arm than with a deeper top. Deeper tops also pull harder on the upper screws, as the page on weight capacity explains.

Studs. Wood studs are 16 or 24 inches on center, depending on stud size and load (IRC Table R602.3(5)). Measure before you cut the top; the bracket spacing has to be a multiple of the stud spacing or go on a ledger board.

Step by step

1. Choose the plan and the size

   Decide between brackets and a drop-front box. Fix the width so the brackets can sit on studs with knee room between them, and the depth for your laptop or screen.

2. Find and measure the studs

   Mark both edges of each stud and measure center to center. Check for outlets and switches in the zone below the desk.

3. Mark the desk height

   Mark the finished top edge at about 29 to 30 inches and subtract the thickness of the top. That line is the top of the bracket arms, or the hinge line of the drop front.

4. Fix the supports into the studs

   Screw the brackets, or the back of the box, into the studs with pilot holes and wood screws long enough to reach well into the wood. Check level before the last screw.

5. Fit the top or the drop front

   Plan A: lay the top on the open arms, leave a small gap to the wall so it can fold, and screw it on with screws shorter than the top is thick. Plan B: hinge the front to the bottom of the box and fit the flap stays exactly as their instructions say.

6. Check the fold and route the cables

   Fold the desk several times. Brackets must lock fully; stays must hold the front level and the catch must keep it shut. Lead charger cables so the desk closes without pinching them.

Hinges, stays and brackets: which part does what

A full-length hinge only joins the front to the box. The flap stay is what holds it: Rockler describes the Sugatsune SDS-C100 as lowering a drop-front desk lid gently, supporting it level for use as a writing surface and keeping it closed with an integral catch. Rockler names no figure for what the open lid can carry and points to the technical documents for which lid weights the stay suits. For a desk you lean on, check that sheet before you build. All four part types are sorted in hinges and locking supports for fold-down tables.

For Plan A, the brackets in our data have seller data only: the 16 in stainless folding brackets^* suit a laptop-depth top, the CLT 24 in brackets^* a deeper one.

Typical mistakes

1. Brackets on neighboring studs. It saves a ledger board but leaves no knee room.
2. A top that is too deep for the wall. More depth means more leverage on the upper screws.
3. Flap stays chosen by looks. They are sized by the weight of the front.
4. Cables in the fold. Lead them along the side so the desk closes without pinching them.

Safety

A desk is leaned on every day. Screw into studs, a ledger board on studs or masonry, never into drywall alone, and keep children from hanging on the open top. Walls can hide cables and pipes; check before you drill and ask a carpenter if you are unsure.
