How to Calculate Fence Materials

Frequently Asked Questions
How far apart should fence posts be?
Standard spacing is 2.4 m (8 ft) centre-to-centre for most residential fences. In wind-prone or exposed areas, reduce to 1.8 m (6 ft).
How deep should fence posts be?
Bury one-third of total post length. For a 1.8 m (6 ft) fence, use 2.4 m (8 ft) posts buried 600 mm (2 ft). In cold climates, go below the frost line.
