DIY Wall-Mounted Folding Workbench: Ledger Board, Folding Brackets and a Top Sized to Your Wall

What you build and what it takes

The finished bench is a top on two locking folding brackets. Open, the brackets lock square and the top is a work surface; folded, the brackets drop and the top hangs flat against the wall. Unlike a ready-made bench, you choose the depth and width yourself – that is the main reason to build one. The garage workbench guide compares the ready-made alternatives, and brackets or a ready-made table weighs the two routes against each other.

Time: an afternoon for one person, longer if you add a ledger board. Cost: budget to mid-range price class, depending on the brackets and the top.

Plan the three numbers first

1. Depth → bracket length. There is no standard for this. As a rule of thumb, choose an arm close to the depth of the top: VIVO puts 15.4-inch brackets under its 18-inch top, so a 22- to 24-inch-deep bench calls for 24-inch brackets. The arm must not reach past the front edge – Mount-It!'s manual says so explicitly for its table. Details are in what bracket length a 24-inch-deep table needs.

2. Studs → bracket spacing and width. Wood studs are 16 or 24 inches on center (IRC Table R602.3(5)). Both brackets need screws in a stud center, so their spacing has to be 16, 32 or 48 inches on a 16-inch wall, or 24 or 48 inches on a 24-inch wall – unless you mount a ledger board. Then choose the width of the top so it overhangs the brackets evenly.

3. Height → ledger line. We found no primary source for a standard standing workbench height. Lifetime's wall-mounted work table sits at 36 inches in its manual's standard setting; for seated work the 2010 ADA Standards set 28 to 34 inches. Clamp a scrap board at the planned height and stand at it before you decide.

Tools and material

• Drill and driver, bits as named by the bracket and screw makers
• Stud finder, tape measure, pencil, level at least as long as the ledger
• Two locking folding brackets with arms close to the top's depth
• A straight ledger board long enough to cross at least two studs, thick enough for the bracket screws
• Screws for the ledger that reach well into each stud; screws for the brackets that suit the ledger or stud
• The top: plywood or a solid board, cut to your depth and width
• Optional: fold-out legs and locking leg hinges for the front edge

Step by step

1. Plan depth, width and height

   Write down the top depth, the bracket length, the bracket spacing and the height of the finished top edge. Check the spacing against your measured stud spacing, not against an assumed 16 inches.

2. Find and mark the studs

   Run the stud finder across the whole zone, mark both edges of each stud and the center between them, and measure center to center. Check for cables and pipes before drilling; if in doubt, use a detector or ask an electrician.

3. Mount the ledger board

   Draw a level line for the top of the ledger. Hold the board on the line and screw it into every stud it crosses. The screws have to pass through the board and drywall and reach well into the stud. If you are unsure about screw type and length, ask a contractor or the screw maker.

4. Fix the brackets

   The top of the bracket arms sits at the top edge minus the thickness of the top. Mark that line, hold each bracket plate on it and screw it to the ledger, or into a stud center if it lands on one. VIVO's manual, for example, aligns three bracket holes with the stud center and leaves three unused. Check both brackets with the level, and with a board across them, before you tighten the last screw.

5. Cut and attach the top

   Cut the top so the open arms end just behind the front edge. Keep a gap between the back of the top and the wall so it can fold – VIVO asks for at least 3/8 inch on its bench. Screw the top to the arms from below with screws shorter than the top is thick.

6. Check the fold and load it gradually

   Fold the top down and up a few times, make sure both latches engage, and check that the folded top clears anything below it. Then load it step by step and look for movement at the ledger and bracket screws.

Optional: legs under the front edge

A pair of fold-out legs carries part of the load straight to the floor, so less of it pulls on the wall screws. That is how the Lifetime 80421 is built. For a DIY bench, small self-locking leg hinges such as the TopDirect locking hinges^* hold a leg at 90 degrees, according to the seller; the listing's 500 lb figure does not say per hinge or per set. The hinge types for fold-down tables are compared under hinges for fold-down tables.

Typical mistakes

1. Bracket spacing planned around the middle of the top instead of around the studs.
2. Ledger screwed into drywall only. A ledger helps only if it sits on studs. Hollow-wall anchors carry far less than their headline figure: TOGGLER's sheet notes that industry standards recommend one quarter of the ultimate test load.
3. Arms too short for the top. A 16-inch arm under a 24-inch top leaves a third of the depth unsupported.
4. Trusting the bracket's printed figure. None of the listings in our data says whether it is per bracket or per pair, or for which wall. The page on folding shelf brackets lists the printed figures side by side.

Which brackets – or a ready-made bench?

The Wallmaster 24-inch brackets^* are an alternative with seller data only. If you would rather rely on maker data, the VIVO 43 x 18 workbench^* is the ready-made version of the same idea, rated 110 lb on wood stud, brick or concrete by VIVO.

Safety

A falling top can injure. Do not climb on the bench, keep children from hanging on the open top, and do not exceed what your fixing can carry. Walls can hide cables and pipes. If you are unsure about the wall, the ledger or the screws, ask a contractor before you load the bench.
