How deep should fence posts be?

Bury posts at least 1/3 of their total length — 24 inches deep for a 6-foot fence, or below the frost line in cold climates.

Should I use cedar or pressure-treated lumber?

Cedar is naturally rot-resistant and looks great but costs more. Pressure-treated pine is more affordable and equally durable when maintained.

How far apart should fence posts be?

Standard spacing is 6-8 feet on center. Closer spacing (6 feet) provides more structural strength in high-wind areas.
