Fence Paint Area & Quantity Calculator

Estimate paintable area and paint quantity for fences from run × height, mixed panels, or a known area. Switch units, set one-side/both-side, subtract gates, adjust coats, waste, primer, and coverage, then copy a shareable URL.

Net paintable area 0 m²
Total paint 0 L
Net area is based on run × height with your sides, complexity, and non-painted inputs.
How to use 1) Choose a mode: total run × height, per-panel mix, or known area. 2) Set paint sides, complexity, non-painted gates, coats, waste, primer, and coverage. 3) Review net area and paint gallons/liters, then copy the URL to share.
Unit system

Enter total fence run and average height. Pick the fence style to apply structure spacing, choose one side or both, and add a small percentage for posts/steps.

Advanced coverage overrides

Overrides replace presets when filled. Absorption divides the coverage to account for thirsty substrates.

    Notes & FAQ

    What counts as fence complexity?

    Use the “extra area” percent for post faces, brackets, steps, lattice accents, and uneven grades. Keep it small (5–15%) so waste and absorption remain the main buffers.

    How should I model spaced pickets or wire fences?

    Select the closest type: spaced pickets use a 0.65 structure factor, 2–3 rail ranch fences use 0.45–0.60, and wire + posts uses 0.25. Custom lets you set your own ratio if boards are unusually wide or narrow.

    Do I need primer?

    Primer helps with bare wood, metal, or masonry. Turn it off for scuff-sand and recoat jobs on existing coatings, or when using self-priming solid paints per the label.
