Fence Materials Calculator

Posts, rails, pickets, and optional concrete.

Fence Materials Calculator

Estimate a simple fence build from fence length, post spacing, picket width, gap, rails per bay, and waste allowance. Optional concrete-bag, fastener, and material-price fields keep the workflow static and deterministic.

This static version supports one gate deduction and one bags-per-post estimate rather than a full corner-post or custom post-hole workflow.

Posts are calculated from the effective fence run after one optional gate deduction. Advanced gate-post, corner-post, and custom panel logic remain later-phase extensions.

Fence calculator FAQ

Does the gate opening remove posts too?
The simple static workflow reduces the filled fence run. It does not apply custom gate-post or corner-post overrides automatically.

Can I use this for concrete too?
Yes for a quick bags-per-post estimate. For bag-yield-based concrete math, use the dedicated concrete calculator as well.
