Fence Post Spacing Calculator

Evenly space posts across any run — wood or T-post, gate- and slope-aware — with rail counts and a material cost estimate.

Gates

Every gate gets two 6×6 posts set 36″ deep in concrete — never hinge a gate on a T-post.

Wood line posts (4×4 / 6×6): 6–8 ft on center; 2–3 rails per bay.
Metal T-posts: up to 10 ft on center; drive 24 in — no concrete needed.
Gate posts: two 6×6 (or steel) posts per gate, set 36 in deep in concrete; gate openings are deducted from the rail run.
Sloped terrain: cut the max span ~15% and add ~10% rail length for raked or stepped rails.
Costs: national-average material estimates (PT lumber, ~$6 per concrete bag) — confirm local pricing, codes and frost depth.
