How deep should a footer be for a patio?
Dig a hole roughly 24 inches in diameter. If you’re using a smaller tube form, dig the hole twice the diameter of the form. Dig the hole to a depth 6 inches below the desired position of the form’s bottom. For example, if your footing depth requirement is 12 inches, dig the hole 18 inches deep.

Can a precast footer be used for a deck post?
These precast footing blocks accept only a 4×4 post and won’t comply to code in areas where the footing base must sit more than a few inches below grade, which it almost always does.
