What size concrete piers do I need?
For sizing pier diameters for small foundations, the rule of thumb is “1 inch per foot of span.” Thus, a deck that spans 8 ft. will stand comfortably on 8-in. -diameter piers, while a deck that spans 10 ft. requires 10-in. -diameter piers.
What size sonotube for a deck?
A good size for a common backyard deck is a 10″ or 12″ diameter for the sonotube and a 20″ base diameter. Of course, you can get a 24″ base size and it will spread weight over an even greater surface area. The one down side to this is the extra digging involved.

When setting vertical rebar in a sonotube, use a plastic spacer in the center of the sonotube on the bottom. Place the sonotube over the plastic spacer, then insert the rebar on top of the spacer.
