hi all, can anyone elaborate on the way the footing size is determined for pergolas? there is a dependency between the roof area supported by each post, the type of the awning attached or free standing and the footing size.

how to calculate footing size. a footing is the cement slab that is used to support a structure by distributing weight over a defined area. the amount of cement that is needed for the footing is obtained by calculating cubic feet. the cubic feet of cement required for the footings is calculated by using the dimensions of the slab that will support the structure.
pergola post information includes the size and installation of the posts that are the legs for your pergola. it is important that your pergola is level and well anchored in order to ensure proper installation and structural integrity.

the depth of your hole should be about 1/4 of the height of your post. for a 6x6 post, the diameter of the holes should be about 12 inches square. as a rule the width of your post hole should never be less than 10 inches. you want holes deep and wide enough to easily support a standard 4x4 post.

i'm in earthquake country, so i like pouring my own piers footings , sized based on site soil and structure load, concrete coped away from the base of the posts to shed water away minimizing moisture contact. you didn't provide a pic or description of the pergola style, so i have no idea of the load, but 8x14 is not very intimidating for a
