Triangular Pergola Dimensions

Both Timber and Lattice Triangular Pergolas have a roof frame that is 144"L diagonal with 102" sides. They are 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 posts are full-dimension 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 8.5'L posts along with the post trim pieces to hide the metal fasteners.

Approx. Weight of Triangular Pergolas: 350 lbs.

Timber Triangular Pergola Roof Dimensions

There is 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 2x2's spaced 18" on center. If you want more shade, we can move them to 15" or 12" on center for approximately $15% more to cover the additional lumber needed. Just let us know when you're placing your order.

Lattice Triangular Pergola Roof Dimensions

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

Lattice Panels

Lattice Panel frames are one-inch thick. Lattice is 1/4" thick attached with galvanized staples. Standard panel dimensions are 24"H x 76"L. Panels can be placed at any height at time of assembly. Approx. Weight: 40 Lbs.

You can also order this pergola with 40"H x 76"W panels for greater coverage. For complete privacy on both sides, four 40"H x 76"W panels are required.
