Sawhorses support everything from cutting operations to painting surfaces to temporary workbenches. A pair of solid sawhorses is among the most useful shop fixtures you can build, and they take less than an hour to construct from a single 2x4 stud. This classic design uses compound-angled legs that splay outward for stability and a simple I-beam top that resists deflection under heavy loads.

Build a Sturdy Sawhorse

Design

This sawhorse stands 32 inches tall (comfortable for cutting operations when adding the workpiece height) with legs splayed at 15 degrees for stability. The top beam is a 36-inch long 2x4 with a 2x4 crosspiece at each end forming an I-beam section.

Dimensions:

Height: 32 inches (adjustable to your preference)
Top beam length: 36 inches
Leg splay: 15 degrees outward in both directions (compound angle)
Footprint: approximately 32 x 24 inches at the floor

Materials (Per Sawhorse)

Three 2x4 studs, 8 feet long
3-inch deck screws or 16d nails
Wood glue (optional but adds strength)

Cost per sawhorse: $8 to $14 in lumber.

Always build sawhorses in pairs. Two identical sawhorses support sheet goods for cutting, serve as a painting platform, and function as a temporary workbench with a plywood top laid across them.

Cut List (Per Sawhorse)

Part	Quantity	Length	Angle
Top beam	1	36 inches	Square ends
Legs	4	28 inches	15-degree compound miter at top
Top gussets	2	20 inches	15-degree bevel on each end
Bottom stretcher	1	24 inches	Square ends

Cutting the Legs

The legs require a compound miter — they splay outward both side to side and front to back. Set your miter saw to 15 degrees miter and 15 degrees bevel. Cut the top of each leg at this compound angle so the leg sits flush against the top beam and the angled gusset.

If the compound miter is too complex, simplify: cut the leg tops at a straight 15-degree bevel (splay in one direction only). The sawhorse is slightly less stable but still completely functional. Many professional carpenters build sawhorses with single-bevel legs.

Cut all four legs to 28 inches (this produces approximately 32 inches of standing height when the leg is splayed and the beam is added).

Assembly

Top Beam and Gussets

Place the 36-inch top beam flat on the work surface.
Center a 20-inch gusset across each end, flush with the beam top. The gusset extends past the beam on both sides by approximately 6 inches on each side.
Screw or nail through the gusset into the beam end — two screws per connection.

This creates the I-beam cross-section at each end of the sawhorse.

Attaching Legs

Position two legs against one end of the beam assembly, one on each side of the beam, with the compound-angle cuts seated against the beam and gusset.
The legs splay outward — each leg leans away from the beam center by 15 degrees when viewed from the end.
Screw through the legs into the beam with two screws per leg (through the leg face into the beam side).
Screw through the gusset into the top of each leg with one screw per connection.
Repeat for the opposite end.

Bottom Stretcher

Nail or screw a 24-inch 2x4 between the legs on one side, about 8 inches from the floor. This cross-brace prevents the legs from spreading under load. Some builders add a stretcher on both sides for maximum rigidity.

Testing

Stand the sawhorse on a flat surface. It should sit solidly on all four feet without rocking. If one leg is short, trim the others to match (easier than shimming). Place your weight on the top beam — it should not flex, rack, or wobble. A properly built sawhorse supports 500+ pounds.

Variations

Stackable Sawhorses

Cut the top gussets at a slight inward angle so the legs nest when two sawhorses are stacked. This saves storage space in a small shop.

Fold-Flat Sawhorses

Attach the legs to the beam with bolts through slotted holes instead of screws. The legs fold flat against the beam for compact storage. Add a wing nut for quick setup and breakdown.

Heavy-Duty Sawhorses

For supporting sheet goods and heavy lumber during cutting, double the top beam (two 2x4s laminated face to face) and use 4x4 legs. This build supports 1,000+ pounds and serves as a permanent shop fixture.

Low Sawhorses

Build a pair at 18 to 20 inches tall for use as an assembly platform. A sheet of MDF across two low sawhorses creates a large, low assembly table for glue-ups and finishing. The lower height is easier on the back for tasks that require leaning over the surface.

Using Sawhorses

Cutting platform: Lay a sacrificial sheet of foam insulation board across two sawhorses. Place the workpiece on top. Cut with a circular saw or track saw — the blade cuts into the foam without hitting the sawhorses.

Painting support: Lay boards or panels across sawhorses for painting, staining, and finishing. The elevation provides access to all edges and allows finish to drip without pooling.

Temporary workbench: A solid-core door or 3/4-inch plywood panel across two sawhorses creates an instant work surface for home projects in the garage, on the driveway, or at a job site.

Drying rack: Set multiple sawhorses in a row with 2x4 rails spanning between them. Hang stained or finished pieces on the rails to dry.

Storage

Hang sawhorses on wall hooks or stack them in a corner. The most space-efficient storage: hang one sawhorse by the top beam on two large hooks mounted to a wall stud, legs pointing up. Each sawhorse occupies about 36 x 24 inches of wall space and zero floor space.

Bottom Line

One hour and $10 in lumber produces a sawhorse that supports half a ton and serves as a cutting platform, painting support, drying rack, and temporary workbench. Build four — you always need more sawhorses than you think. Keep a pair in the shop and a pair ready for outdoor and job-site work. They are the simplest, most useful project you can build, and every project after this one benefits from having them.
