Common Uses

People use this calculator when they need a quick way to estimate fence posts, post spacing, corners, gates, post-hole concrete, and concrete bags.

Material Estimating: Estimate material quantities, waste factors, rolls, panels, bags, board-feet, sheets, posts, concrete, rafters, or linear feet before ordering supplies.
Measurement: Use dimensions, surface area, spacing, thickness, slope, pitch, coverage, openings, and project measurements to calculate a practical result.
Budgeting: Support rough cost planning by estimating quantities before comparing supplier prices or contractor quotes.
Project Planning: Plan job scope, materials, order quantities, construction assumptions, and home-improvement work before starting a project.

Formula or Method

Posts = ⌈fence length / spacing⌉ + 1 + corners/gates

Example

Example inputs: Total Fence Length: 100 ft; Post Spacing: 8 ft; Number of Corners / Gates: 2
