The easiest way to ensure a pergola is square is to use the 3-4-5 Method. To be certain two lines are 90° to each other, measure 3 feet on one line and place a mark. Then measure the other line 4 feet and make a mark. Measure diagonally between the two places you have marked.
Keeping this in view, what is the average size of a pergola?
For our pergola kits, standard pergola dimensions range from 8×8 to 20×20. Once you take your measurements, you'll know if a standard size will work, or if you'll need to request a custom pergola size.
Additionally, how much should a pergola overhang? Since the roof overhangs the posts, the posts are set in by a few inches at each corner. For most pergolas and pavilions, the ideal setback for the posts is 8 to 12 inches. Our default is 12 inches, but this can be reduced or increased depending on the style and circumstances.
Thereof, how do you measure pergola posts?
Using a tape measure, pull your first measurement from the wall (where the pergola will be attached) to the spot where you would like the outside edge of your posts to land. This is Measurement A. Then, add the overhang to that measurement. The attached Big Kahuna has a 1'6″overhang past the outside edge of the post.

4. Pergolas provide shade. Although they look somewhat unfinished to the untrained eye, pergolas do provide shade.

"22 feet for a span will not work (for 2" x 6" beams). You need at least three support posts and four would be even better."
