The footing should be about 16 x 16 or 18 dia.
Carport post footing size.
Set a simpson epb44 in the new footing to accept the bottom of the post.
The width or diameter can vary from 350mm wide to 600mm wide with the depth varying from 750mm to 1 5m and more.
Leave extra length to be sure you have enough.
The footings will be set 2 5 below finished grade and i ll use simpson strong tie elevated post base anchors epb66 so that i can lay pavers on top of the footing with the pergola post resting on the anchor base at the finished grade of the patio.
Footing is truly sufficient.
They should be at least 101 inches long.

That would certainly work but i am into less concrete by doing the isolated big footings the carport is 36 long x 24 wide w 12 tall columns and a 12 12 roof it is pretty grand w timber trusses 12 o c.
For a roof six foot five inches your posts should be six feet five inches plus the 24 inches of the post that will be planted.
My question is weather or not an 8 dia.
You could use a slightly too long 4x4 to wedge up the end of the beam to relieve the pressure on the post.
Footing systems on expansive soil shall be constructed in a manner that will minimize damage to the structure from movement of the soil.
People often ask us what size footings do they need to concrete the carport posts into the ground.
Use a power auger or post hole digger to dig post holes of about two to four feet deep for the footings.
A carport s post size will vary depending on the height of structure.
Doesn t need to be pretty.
2 lengths of 4 1 2 rebar at 90ยบ in the footing 4 total.
Attached carports can use the supporting structure as framing for one of the sides.
