Fence Calculator

Fence quotes depend on the count of posts and pickets. This tool estimates them from run length and post spacing so you can check a supplier's takeoff.

Your result appears here after you press Calculate.

How it is calculated

  • Sections = run length ÷ post spacing, rounded up.
  • Posts = sections + 1, plus one extra post per gate.
  • Rails = sections × rails per section.
  • Pickets = run length in inches ÷ (picket width + gap), rounded up, with waste.

Assumptions and limits

  • Assumes a straight run with equal sections. Corners, slopes and gates change the count.
  • Height limits, setbacks and permits vary locally. Check with your municipality and your property survey.

Material estimates are for planning and ordering guidance. Coverage, yield and dimensions vary by product, so check the manufacturer's labeling. Structural work, roofing at height and code compliance should be handled by qualified professionals and confirmed with your local building department.
