A folding picnic table with separate benches is easier to carry, repair, and store than a conventional A-frame picnic table. The trade-off is that you build more parts, and the hinges and leg locks need careful fitting. This plan makes a table about 60 inches long by 30 inches wide, with a 29-inch-high top, plus two benches about 60 inches long and 17 inches high.
The dimensions suit four adults comfortably and six in a squeeze. If you regularly seat six, make the table 72 inches long, but expect noticeably more weight and more flex unless you use thicker framing.

Materials and tools
Use straight, exterior-rated lumber. Cedar is lighter and naturally rot-resistant, while pressure-treated pine costs less and is stronger for the price. Cedar is easier to carry but dents more readily. Avoid construction boards with large knots in the legs or long frame rails.
- Five 1×6 boards, 6 feet long, for the table top
- Four 2×4 boards, 8 feet long, for table rails, legs, and braces
- Four 2×6 boards, 6 feet long, for the bench tops
- Two 2×4 boards, 8 feet long, for bench frames and legs
- Four 3-inch exterior strap hinges for the table legs
- Four 2-inch or 3-inch strap hinges for folding bench legs
- 3/8-inch bolts, washers, and locknuts for pivot joints
- Exterior screws, construction adhesive, and exterior finish
You will also need a circular saw or miter saw, drill, 3/8-inch bit, countersink bit, clamps, square, tape measure, and a sander. A box of exterior wood screws is a better choice than ordinary interior screws; drywall screws rust quickly outdoors and can snap under movement.
Cut list and layout
| Part | Quantity | Finished size | Purpose |
|---|---|---|---|
| Tabletop boards | 5 | 1×6 x 60 in. | Five boards form the 30-inch top |
| Table end rails | 2 | 2×4 x 27 in. | Hold the tabletop together |
| Table side rails | 2 | 2×4 x 57 in. | Support the long edges |
| Table legs | 4 | 2×4 x 28 in. | Folding table support |
| Bench tops | 4 | 2×6 x 60 in. | Two 12-inch-wide seats |
| Bench rails | 4 | 2×4 x 57 in. | Under-seat support |
| Bench legs | 4 | 2×4 x 16 in. | Folding bench support |
These dimensions assume actual 1×6 boards are about 5 1/2 inches wide and actual 2×6 boards are about 5 1/2 inches wide. Check your lumber before cutting. A 1/8-inch difference across five tabletop boards can change the finished width enough to affect the leg clearance.
Build the tabletop
Lay the five tabletop boards face down on a flat surface, leaving a 1/8-inch gap between boards for drainage. Arrange the best-looking faces upward and alternate end grain direction where practical; this can reduce cupping.
Position the two 57-inch side rails about 3 inches in from each long edge. Fit the 27-inch end rails between them, creating a rectangular frame below the boards. Apply a thin bead of adhesive to each rail, clamp the assembly square, and drive two 2-inch exterior screws through each tabletop board into every rail. Do not overtighten; crushed fibers make loose screw joints.
Measure diagonally from corner to corner. Adjust the frame until both diagonal measurements match within 1/8 inch. Sand the top edges and corners with 80-grit paper, then finish with 120 grit. A small 1/8-inch roundover prevents sharp corners from becoming uncomfortable handles.
Install the folding table legs
Place one 28-inch leg inside each end of the tabletop frame. The legs should pivot inward beneath the top, not outward past the tabletop edge. Use a 3/8-inch bolt through each leg and side rail, positioning the pivot about 3 inches below the tabletop and centered across the rail thickness.
Use washers on both sides of each pivot and tighten the locknut until the leg moves firmly but freely. If the leg binds, the holes are not aligned or the nut is too tight. Do not rely on friction alone to hold the table open. Add a removable 2×4 spreader between each pair of legs, or install a folding brace with a positive locking mechanism.
A simple removable spreader can be cut to fit between the legs after the table is standing. Drill a 3/8-inch hole near each end and use quick-release pins. This is cheaper and more reliable than a complicated folding brace, although it adds one loose part that can be misplaced.
Build the separate benches
For each bench, join two 2×6 boards with two 57-inch 2×4 rails underneath. Set the rails about 4 inches in from the ends, apply adhesive, and use two screws per board at each rail. Keep the bench square by matching diagonal measurements.
Attach one folding leg beneath each end. Position the leg pivots about 3 inches in from the bench ends. The 16-inch legs, combined with the roughly 1 1/2-inch seat thickness, produce a seat height close to 17 1/2 inches. Test the height beside the table before final tightening. If you prefer a lower seat for children, cut the legs to 14 1/2 inches.
Install a removable stretcher between the bench legs if the benches rack sideways. A stretcher is especially worthwhile when using cedar, which is lighter but less rigid. Keep the stretcher low enough that it does not hit a person’s ankles.
Choose hardware and finish
| Choice | Best for | Trade-off |
|---|---|---|
| Galvanized steel hardware | Pressure-treated pine on a budget | Less expensive, but can eventually stain wood |
| Stainless steel hardware | Cedar, coastal areas, and frequent wet exposure | Costs more but resists rust and staining |
| Penetrating exterior oil | Natural appearance and easy maintenance | Needs reapplication, often every one or two years |
| Exterior paint | Maximum color and UV coverage | More surface preparation and peeling is harder to repair |
For a budget build, galvanized hardware and an exterior penetrating finish are fine if the table is stored under cover. If it will sit outside all summer, stainless fasteners and a quality exterior finish are worth considering. Use stainless exterior screws in cedar or near salt water.
Test, correct, and store it
Set the table and benches on level ground and load each seat gradually. Sit near the middle of each bench, then near both ends. If a bench rocks, check whether one leg is longer before adding shims. If the table twists, square the frame again and inspect the leg pivots.
Do not carry the open table by one leg or expect the hinges to support a lifted load. Fold the legs inward, secure them with a strap, and store the pieces vertically under a roof with air circulation. Before each season, inspect loose bolts, cracked legs, and soft end grain. Replace damaged structural parts rather than simply adding longer screws.
