Sod Calculator

We sum your sub-areas (or take your total), add the waste buffer, then divide the post-waste order area by each coverage constant and round up — you can't buy a fraction of a roll, slab, or pallet. The pallet remainder is the full pallets plus the loose slabs that cover what's left over.

total_ft2 = Σ (length × width)        (or your entered total)
order_ft2 = total_ft2 × (1 + waste% / 100)

rolls   = ceil(order_ft2 / rollFt2)     (default rollFt2 = 10)
slabs   = ceil(order_ft2 / slabFt2)     (default slabFt2 = 2.66)
pallets = ceil(order_ft2 / palletFt2)   (default palletFt2 = 450)

pallet remainder:
  fullPallets    = floor(order_ft2 / palletFt2)
  remainderFt2   = order_ft2 − fullPallets × palletFt2
  remainderSlabs = ceil(remainderFt2 / slabFt2)

cost (optional, priceUnit drives the unit):
  pallet → pallets × price   roll → rolls × price
  slab   → slabs × price     sqft → order_ft2 × price
  cost / sq ft = cost / total_ft2   (finished lawn, not order area)

Default coverage — pallet 450, roll 10, slab 2.66 sq ft — and the 5–10% waste band come from Inch Calculator, The Grass Outlet, and Sod Solutions. Coverage varies by region, grass type, and supplier (Southern slab pallets ≈ 450 sq ft; Northern large-roll pallets ≈ 500–700; slabs run 2.66–2.75 sq ft), so every constant is editable to match your supplier's quote.
