A portable sawhorse table gives you a stable surface for sanding, assembling, painting, and cutting stock with a handsaw. This design uses two folding sawhorses and a removable plywood top, so the parts store flat and the table can be set up by one person. It is not a substitute for a certified workbench or a secure cutting station: clamp the work, and keep heavy loads within the limits of your sawhorses.

Choose the size and capacity
The plan below makes a top about 24 by 48 inches, a useful size for backyard repairs and small projects. A 24-by-48-inch top cut from 3/4-inch plywood weighs roughly 20 pounds, depending on the sheet. The finished table will be heavier once you add the sawhorses, but each component is manageable to carry separately.
For occasional light-duty work, inexpensive folding plastic sawhorses may be adequate. For a table that will take repeated clamping, bumping, or heavier boards, sturdy steel or wood models are a better bet. Check the pair’s stated capacity, but do not assume that rating means the plywood top can safely support that full load in every arrangement.
Materials and tools
- One 3/4-inch exterior-rated plywood panel, at least 24 by 48 inches
- Two folding sawhorses of matching height
- Four short pieces of 1-by-2 lumber for underside locating cleats
- Exterior screws, about 1 1/4 inches long
- Measuring tape, pencil, drill/driver, saw, and sandpaper
- Optional: exterior paint or water-resistant finish
Use plywood with a sound face and no loose plies near the edges. Exterior-rated plywood tolerates damp air better than standard interior sheathing, but it is not waterproof. A 3/4-inch exterior plywood panel is a sensible choice if the table may be left outside briefly. If it will always be stored dry, decent construction plywood is cheaper and usually fine.
A circular saw makes the straight top cut quickly. If you do not own one, ask the lumberyard to cut the panel to size; a handsaw works too, but keeping a long cut square takes care. A circular saw is worth buying only if you expect to use it on other projects.
Compare the support options
| Support type | Best for | Trade-off |
|---|---|---|
| Folding plastic sawhorses | Light projects, occasional use, low cost | Can flex or slide; check the feet and load rating |
| Folding steel sawhorses | Frequent setup and heavier work | Heavier to carry; exposed steel can rust if stored wet |
| Home-built wooden sawhorses | Custom height or repairable shop gear | More build time and less compact folding unless designed carefully |
Choose a pair with a top rail wide enough to support the plywood without placing its edge right at the rail’s edge. A pair of folding sawhorses is the fastest route. Before buying, compare the working height and folded size, not just the advertised capacity.
Cut and prepare the top
Mark a 24-by-48-inch rectangle on the plywood. Support the sheet on scrap lumber or foam so the offcut cannot pinch the saw blade. Cut just outside the line, then sand the edges smooth and ease sharp corners. If the panel has a factory edge that is square and undamaged, use it as one of the long edges.
Check the top for bow by laying it on a flat surface. A slight crown can be placed upward; a twist that makes the panel rock is a reason to choose another piece. Seal the faces and edges if the table will see damp weather. Pay particular attention to cut edges, which absorb moisture faster than the factory face.
Fit the locating cleats
The cleats stop the top from sliding sideways on the sawhorse rails. Set the plywood upside down on a flat surface. Measure the spacing between the two sawhorse rails when they are open and locked. Mark where each rail will sit, then position a pair of 1-by-2 cleats along the outside edges of each rail, leaving roughly 1/8 inch of clearance. That small gap lets the top drop into place without binding.
Cut four cleats to fit the rail locations, typically 10 to 12 inches long. Predrill screw holes to reduce splitting, then fasten each cleat to the plywood with two or three 1 1/4-inch screws. Keep screws at least 3/4 inch from the plywood edge and confirm they do not poke through the top. The cleats should guide the rails, not squeeze them tightly; wood swells outdoors, and a tight fit can make setup frustrating.
If your sawhorses have unusually narrow or shaped rails, make a cardboard template first. A poor cleat fit is a common failure: the top rocks, shifts during sanding, or will not seat after the wood gets damp. Recheck the spacing with the horses open and locked, not folded.
Set up and test the table
Open both sawhorses fully and engage their locks. Place them parallel, with their rails about 30 to 36 inches apart and centered under the top. Lower the plywood so the rails sit between the cleats. Push gently from each side to check for movement, then press down at the corners. If the table rocks, correct uneven ground or adjust the cleats; do not compensate by stacking loose scraps under a foot.
Test with a modest load before using the table for a project. Keep heavy items over the rails rather than at the center of the plywood span. The panel can bend if you pile weight in the middle, especially with the horses set far apart. For cutting, clamp the work securely and keep the blade clear of the top; a sacrificial mat or separate cutting surface helps prevent accidental cuts into the plywood.
Storage and maintenance
Lift off the top before folding the sawhorses. Store the plywood flat or on edge with support along its length; leaning a large panel loosely against a wall can make it bow or fall. Wipe off water and let the components dry before storage. Inspect the cleats and screws now and then, particularly after the table has been left outdoors. Replace cracked cleats or loose fasteners before the next use.
