Triangular Lattice Pergola on Left and Standard Timber Pergola on Right

Both of our Triangular Pergolas (Lattice version and Standard Timber) have the same size timbers and roof frame sizes:

The roof frame is 144"L diagonal with 102" sides and 72"D from center of the diagonal to the rear corner. It is an isosceles triangle with the rear corner being the 90 degree angle and the two other corners are identical 45 degree angles.

The timber roofed pergola has a 9" roof overhang on the front beyond the long diagonal, so the roof dimension has an 81" depth. The timber roof style has the 2 x 2s spaced 18" on center. If you want more shade, we can move them to 15" or 12" on center. Just let us know when you're placing your order.

The lattice panel roof has an overhang on all three sides. The rooftop dimensions are 86"H X 160"L X 80"W. Roof overhang is 12" beyond roof frame.

Full-dimension vertical columns are 4" X 4" X 10'L unless you request a different size. This allows you to bury the posts 24" in the ground and still have plenty of height. If you are going to bolt the posts to concrete, we would send you 8 1/2'L posts along with the post trim pieces to hide the metal fasteners.

Weight: 350 Lbs.

Lattice Panel frames are one-inch thick. Lattice is 1/4" thick redwood attached with galvanized staples. Panel dimensions as shown in photo: 24"H X 76"L Weight: 40 Lbs. Panels can be placed at any height at time of assembly. You can also order this pergola with 40"H X 76"L panels for greater coverage.
For complete privacy on both sides, four 40"H X 76"W lattice panels are required.
