I used to do shade sail installs. My engineer would make footers skinny and deep. I had a hard dog once and asked to go more shallow and he said a rough idea is for every 1" lost in depth to gain 6" in width. Well. I move into Aluminum patio cover world and a guy that is not an engineer says it is better to go wider than deeper. My engineer explained that the pier footing was using the psi of the earth to hold the pier basically. This other guy says his engineer explained that it is looked like a wide base plate of concrete to hold the cover. And when it gets a force one direction it is pushing into the ground and that holds it. This sounds like a spread footer to me which my engineer explained that those mostly just use volume of concrete to hold it and a lot of concrete to do so. I called my engineer that does both but he won't give me an answer unless I provide a job name and number that he did the engineering on to get the exact specs on. Deeper/skinnier to me gives more depth and a little less concrete but also more imbed and a stronger post. Hopefully someone on here might know. Tyvmia
