How deep should footings be for a pergola?

Dig openings in the places for the pergola’s supports, ensuring each hole’s diameter is at least 12 inches and the depth is at least one-third the height of the post. If each post is 12 feet long, then each hole must be 4 feet deep. In this case, the pergola would exceed 8 feet tall.

How do you make a hole for a pergola?

Dig holes in the locations for the pergola’s posts. Make each hole at least 8 inches in diameter. Make each hole’s depth 6 inches below the frost line in your area. Slide a concrete tube form to the bottom of one hole. Cut off the tube form 6 inches above ground level by using a utility knife.
