How to use the undefined
Enter the total fence length, height, and how far apart posts will sit (6 to 8 feet is typical). Set the number of rails per section, the number of gates, and each gate's width. The tool subtracts gate openings, then estimates posts, panels, rails, and the concrete needed to set the posts.
Formula and methodology
Fence line = total length − (gates × gate width). Sections = fence line ÷ post spacing, rounded up. Posts = sections + 1 + (2 per gate). Panels = sections. Rails = sections × rails per section, plus waste. Concrete assumes about 1 cubic foot per post hole.
Worked example
Fence: 100 ft, one 4 ft gate, 8 ft spacing, 3 rails. Fence line = 96 ft ÷ 8 = 12 sections. Posts = 12 + 1 + 2 = 15 posts, 12 panels, 36 rails. Concrete ≈ 15 cu ft. Enter the values above to confirm.
Helpful measurement tips
- Set posts at least one-third of their height deep, plus gravel for drainage.
- Gates need sturdier posts — consider larger holes and more concrete.
- Confirm property lines and call before you dig for buried utilities.
