  "summary": "Linear feet, posts, and cost to fence a 1-acre lot assumed square.",
  "description": "A full acre (43,560 square feet) fenced on all sides assuming a square shape needs about 835 linear feet of perimeter fencing. This calculator defaults to that figure and returns total posts and material cost for your chosen fence style, fully adjustable for irregular lot shapes.",
  "formula": "Perimeter (square lot) = 4 × √(Area). Posts = Perimeter ÷ Post Spacing + 1. Cost = Perimeter × Price per Foot + Posts × Post Price.",

    {
      "q": "Is it cheaper per foot to fence a larger lot?",
      "a": "Material cost per foot stays the same, but labor cost per foot often drops on larger contiguous runs since crews spend less time relocating equipment relative to footage installed."

    {
      "q": "Should I fence for livestock or privacy differently?",
      "a": "Yes — livestock fencing (woven wire, electric) is usually far cheaper per foot than privacy wood or vinyl fencing, so update the price-per-foot field to match your fence type."
