Picnic tables scare people off because of the angles, so this design uses exactly one: 25°. The legs, the cross supports — every angled cut in the build is the same saw setting, which means you set the bevel once, cut everything, and the geometry takes care of itself. The rest is straight crosscuts in 2x6s.
The assembly order is the actual insight here. The tabletop gets built first, face down on a flat surface, squared by matching diagonals — and then everything else attaches to it. The tabletop IS the reference surface. Most wobbly picnic tables were built legs-first on an uneven driveway; this one inherits its flatness from the top down.
A note on the 12-foot 2x6s: buy them and have the store (or a circular saw in the parking lot) cut them in half. Seven 12-footers fit in nothing anyone drives to a lumberyard, and every piece in this table is 72" or shorter anyway. Apply your finish to the boards before assembly — a picnic table is all gaps and end grain after it's together, and pre-finishing turns a miserable afternoon of brushwork into touch-ups.

Overall cost: $$. Lumber prices vary by region, species, and season, so we give a band rather than a figure we would only be pretending to know.
| Part | Qty | T × W × L |
|---|---|---|
| Tabletop boards, seat supports, and seat boardsFive for the top, four for the two seats, and the seat supports come from the rest. | 12 | 1 1/2" × 5 1/2" × 72" |
| Tabletop supports | 2 | 1 1/2" × 1 1/2" × 34 1/4" |
| Center tabletop support | 1 | 1 1/2" × 1 1/2" × 29 1/4" |
| LegsBoth ends 25° off square, ends parallel, long point to short point. | 4 | 1 1/2" × 5 1/2" × 31 3/8" |
| Cross supportsBoth ends beveled 25° off square, parallel, long point to short point. | 2 | 1 1/2" × 3 1/2" × 32 7/8" |
| Under-seat supportsOptional stiffeners under the seat span — worth adding if the table will see standing-on. | 2 | 1 1/2" × 3 1/2" × 61" |

Lay the five 2x6 tabletop boards out on a flat, level surface with about a 1/4" gap between boards. Square the top by measuring both diagonals and nudging until they match — a tabletop that's a parallelogram stays a parallelogram forever once the supports go on.
Screw the two longer 2x2 supports across the boards, 4" in from each end, then the shorter 2x2 across the center. Two 2-1/2" screws into each board.
Cut the four legs at 25° off square — both ends, parallel, measuring long point to short point. Cut all four with the same saw setting.
Attach each pair of legs to the 2x2 end supports so they cross into the A-frame. The angle does the splay; your only job is keeping the leg tops tight against the tabletop.
Flip the table upright and check it stands level without rocking — fix that now by adjusting a leg, not later by shimming a corner.
Cut two scrap blocks to 11" and stand them under each seat support to set its height. Slide the support until the overhang is equal on both ends, then attach with four screws per joint. Four, not two — the seat support is a cantilever with a person on the end of it.
Check the table is level and the legs are plumb, then cut the two cross supports — same 25° setting, this time as a bevel, long point to long point, ends parallel. They run from the center of the tabletop down to each seat support, triangulating the whole frame.
The second one is the awkward one: at the top, the first support blocks a straight shot, so drive those screws at an angle around it into the end of the second support. Ugly is fine here; nobody ever looks under a picnic table.
Attach two 2x6 seat boards per side to the seat supports, gapped like the tabletop, screwed at every crossing.
If the table will host people who STAND on the seats — and every picnic table eventually does — run the optional 61" 2x4 on edge between the seat supports under each seat. It turns a bouncy span into a solid one for one board's worth of money.
