  "summary": "Convert a room's perimeter into linear feet of baseboard, accounting for doorways and waste.",
  "description": "Baseboard is sold by the linear foot or in fixed-length boards, and the amount needed is based on a room's perimeter rather than its floor area, with door openings subtracted out since baseboard doesn't run across a doorway threshold. This calculator takes your room's total perimeter and the combined width of all door openings, subtracts the openings from the perimeter to get the actual run length, then adds a waste factor to cover mitered corner cuts, which lose a small amount of material at every inside and outside corner, plus the reality that boards come in fixed lengths (typically 8, 12, or 16 feet) that rarely divide evenly into a room's wall runs without some offcut waste. A 10% waste factor is standard for a simple rectangular room, while rooms with lots of corners, closets, or angled walls should use 15%+ since more corners mean more mitered cuts and more small offcuts that can't be reused elsewhere in the room.",

    {
      "q": "Do I subtract doorways from the room perimeter?",
      "a": "Yes, baseboard doesn't run across a door opening's threshold, so subtracting the total width of all door openings from the perimeter gives the actual linear footage of baseboard needed."
    },
    {
      "q": "How much waste should I plan for baseboard?",
      "a": "10% covers a simple rectangular room with standard 90-degree corners, while rooms with more corners, closets, bump-outs, or angled walls should use 15% or more since each additional corner requires a mitered cut that loses material."
    },
    {
      "q": "What standard lengths does baseboard come in?",
      "a": "8, 12, and 16-foot boards are the most common standard lengths at most lumber yards and home centers, and choosing a length that minimizes seams along your longest wall runs reduces both material waste and visible joints."
    },
    {
      "q": "Should I round up to a whole board or buy by the linear foot?",
      "a": "If your supplier sells fixed-length boards, round up to the nearest whole board per wall run to minimize seams; if they cut custom lengths to order, you can buy closer to the exact linear footage needed."
