Fence Calculator – Estimates posts, panels, and materials needed f...

The Fence Calculator estimates posts, panels, and materials needed for a fence based on total length. This Fence Calculator helps you calculate the exact quantity of materials needed for your project, saving you from costly over-ordering or frustrating under-ordering. Add a 5–10% waste factor to any result before purchasing.

The formula behind this calculator: Number of posts = fence length / post spacing + 1; panels are calculated similarly by section width. As a practical example: A 100ft fence with posts every 8ft needs about 13-14 posts. All results are calculated instantly in your browser — no data is stored or transmitted.

Fence Calculator FAQ

What does the Fence Calculator calculate?

Estimates posts, panels, and materials needed for a fence based on total length.

Does this account for irregular shapes or obstacles?

Standard shapes only. For irregular areas, divide into rectangles/triangles, calculate each section, and subtract fixtures (doors, windows, islands) manually.

Can I use this for a contractor quote?

Yes as a starting point. Contractors will measure precisely on-site, but this gives you a strong baseline to verify their estimates.

Does this work on mobile?

Yes — fully responsive and optimised for smartphones, tablets, and desktop browsers.
