  "summary": "Square footage used by storage, aisles, staging, and offices vs. total leased space.",
  "description": "Total leased warehouse square footage splits into storage racking footprint, aisle space, staging/dock areas, and office/support space, and knowing that split tells you whether you actually have a capacity problem or a layout problem. Many operations that feel 'full' are actually running excessive aisle width for the trucks they use or have staging areas sized for a peak that only happens six weeks a year. This calculator takes your total leased square footage and the allocation across these functional zones and computes utilization percentages for each, flagging when storage footprint is a low share of total space — a signal that a layout redesign, narrower aisles, or mezzanine addition could free up capacity without adding a single square foot of new lease.",
  "formula": "Storage utilization % = Storage footprint ÷ Total leased sq ft; repeated for each functional zone.",

  "faq": [
    {
      "q": "What's a healthy storage share of total warehouse space?",
      "a": "Well-designed distribution centers typically get 55-65% of total footprint into actual storage racking, with the rest split across aisles, staging, docks, and office space. Below 45% storage share usually means aisle widths are wider than the material handling equipment requires, or staging areas are oversized for average (rather than peak) volume."
    },
    {
      "q": "How much space do narrow-aisle trucks save versus standard forklifts?",
      "a": "Standard counterbalance forklifts need aisles around 12-13 feet wide; narrow-aisle reach trucks can work in 8-10 foot aisles; very narrow aisle (VNA) turret trucks can operate in 5-6 foot aisles. Moving from standard to VNA can increase storage footprint 20-30% in the same building, though VNA trucks and guided rail infrastructure cost significantly more than standard forklifts, so the payback depends on how storage-constrained you are."
    },
    {
      "q": "Why is staging area often oversized?",
      "a": "Staging is frequently sized for the worst peak day (holiday season, major promotion) rather than average daily flow, which leaves it mostly empty the rest of the year. A better approach is sizing staging for a realistic 90th-percentile day and handling true outlier peaks with temporary overflow space or off-site trailer staging instead of permanently dedicating square footage to it."
    },
    {
      "q": "What does unaccounted square footage usually turn out to be?",
      "a": "It's often either measurement error in the initial space audit or genuinely unused/dead space — awkward building corners, columns with unusable clearance around them, or areas blocked by fire code clearance requirements. A physical walk-through with a tape measure or laser measure against the lease drawing usually resolves the gap."
