A folding picnic tray is a small project with a useful payoff: it keeps food and drinks off damp grass, then folds flat for storage or transport. This design has a 24-by-16-inch top, two folding leg frames, and a center brace on each end. It suits a lawn, picnic area, or level campsite. It is not a stool or a place to sit, and it should not be used on a steep or rocky slope.

Design and materials
Use straight, dry lumber and exterior-rated hardware. Cedar resists rot and is light, though it dents easily. Pine costs less and works well if you seal it carefully; expect more weight and check it for knots near screw locations. For the top, use three 1-by-6 boards cut to 24 inches. Their actual combined width is usually about 16½ inches, so trim the assembled panel to 16 inches if you want the stated finished size.
For the legs and braces, use 1-by-2 stock. The dimensions below are a starting point: leg length is 14 inches, giving a tray height of roughly 15 inches with the top attached. That height is comfortable for ground seating but may be low for a folding camp chair. Test it against your usual seat before cutting.
| Material | Advantages | Trade-off |
|---|---|---|
| Cedar | Light and naturally resistant to decay | Costs more and can split if fasteners are driven too close to an edge |
| Pine | Inexpensive and easy to find | Needs a thorough outdoor finish and can warp if stored wet |
| Exterior plywood, ½ inch | One-piece top; fewer gaps for crumbs | Edges need sealing, and a panel can delaminate if water gets in |
Gather three 1-by-6 boards, four 14-inch 1-by-2 legs, four 12-inch 1-by-2 crosspieces, and two 10-inch 1-by-2 braces. You’ll also need exterior wood glue, 1¼-inch exterior screws, two 2½-inch carriage bolts with washers and locknuts, and four small stop blocks. A box of exterior-rated screws is a sensible buy if you do not have suitable fasteners already.
Tools and safety
A saw, drill, countersink bit, tape measure, square, clamps, and sandpaper are enough. A circular saw makes trimming the top easier, but a handsaw works for the short cuts. Wear eye protection, and clamp pieces before drilling. Choose a pair of small woodworking clamps only if you don’t already own clamps; they are convenient, not essential.
Build the top
Lay the three top boards edge to edge on a flat surface. Check that their ends line up, then spread a thin, even layer of exterior glue along the edges. Clamp the panel across its width and drive two screws through the underside battens into each board. Use two 1-by-2 battens, each about 14 inches long, placed across the boards roughly 3 inches in from each end. Keep the battens inset from the long edges so they do not interfere with the folded legs.
Pre-drill screw holes to reduce splitting, especially with cedar. Do not rely on glue alone: outdoor temperature and moisture changes can open a joint. Once the glue cures, trim the panel to 24 by 16 inches and soften the corners slightly with sandpaper. If the boards leave narrow gaps, that is acceptable for an outdoor tray; a sealed plywood top is easier to wipe clean but less forgiving if its edge finish is damaged.
Make the folding legs
Build two identical rectangular leg frames. For each frame, position two 14-inch legs 12 inches apart, then fit a 12-inch crosspiece between them near the bottom. Drill pilot holes and screw the crosspiece in place. The frames should be square; measure both diagonals and adjust until they match before tightening the screws.
Mount one frame under each end of the top using a carriage bolt through each leg and the corresponding top batten. Put a washer between moving wood surfaces and another under the locknut. Tighten until the frame moves with firm resistance, not so hard that the wood binds. Keep the bolt line centered on the leg width and well away from its ends to reduce splitting.
Add braces and stops
With the legs open, fit one 10-inch brace between the legs of each frame, about halfway down. Attach each brace with a bolt and washer at both ends, leaving the joints loose enough to pivot. The brace should fold inward when the legs close. Check the motion slowly by hand before loading the tray; if it catches, reposition the brace rather than forcing it.
Fasten a small stop block under the top beside each leg frame. These blocks keep the frames from swinging past their open position. Set them so the legs stand evenly and the tray sits level on a flat floor. Stops should make firm contact, but they must not prevent the frames from folding inward. A tray that rocks on a hard surface may still work on grass, but fix uneven stops rather than assuming the ground will hide the problem.
Sand, finish, and test
Round sharp edges and sand the top to 120 grit. Remove dust, then apply two or three thin coats of exterior oil or outdoor-rated clear finish, following the product’s drying instructions. An exterior wood finish helps limit water staining, but it does not make the tray waterproof. Seal the end grain carefully, and let the finish cure fully before placing food on the surface.
Open the legs and set the tray on level ground. Press down gently at each corner and check for rocking, loose bolts, or braces that slip. Start with a light load—about 10 pounds of food and drink—then increase it only if the frame remains stable. Keep heavy coolers off the tray; a folding frame is less rigid than a fixed table. Wipe it dry after use, fold it only when the finish is dry, and store it under cover. If a leg cracks, a bolt loosens repeatedly, or a stop block pulls free, take the tray out of use until repaired.
