Sod Calculator

What this calculation does not cover

• The area is a single rectangle, length times width, and there is no field for anything you are not sodding — a bed, a path, a patio, a tree ring or a drive sitting inside the span you measured is turfed and paid for in this count. An irregular lawn has to be broken into rectangles and totalled before you type it, because the form offers one length box and one width box, not a list. A bank measured by its footprint rather than up the face also comes back short, since there is no slope term and the plan rectangle is smaller than the ground it covers.
• The waste entry is one multiplier applied to the whole area, so it grows with the size of the lawn while the cutting that actually generates offcuts happens around the boundary. A small plot with a serpentine edge loses a far larger share of its order to trimming than a big square one, and the two are treated identically here. The field also stops at 15 per cent: type more and it hands back 15 with a notice, which is well under what a heavily curved or terraced layout can waste.
• The answer rounds up to whole pallets and the fraction it rounded away is never shown. On the default 450 sq ft (42 m²) pallet a 10 by 8 m (26 ft) lawn works out at 2.01 pallets and is answered as 3, so nearly an entire pallet of living turf turns up spare and has to be laid, given away or binned within a day or two. No piece count is produced either, which is the number you would need to talk a supplier into a part pallet or a handful of extra rolls.
• Everything after the area rests on the coverage figure you type, and it is taken on trust: nothing checks it against grass species, cut thickness or how the supplier rolls the sod, and the result is badged high confidence whether that number came off a delivery ticket or out of the air. Because it sits in the denominator the sensitivity is direct — a pallet that really covers 400 sq ft (37 m²) rather than the 500 you entered leaves you a quarter short. The field caps at 700 sq ft (about 65 m²) per pallet, so contractor big rolls and slab-cut orders that cover more than that cannot be described, and entering the cap instead will undercount them.
• Only the plan area is modelled; sod's own thickness is not an input anywhere in the arithmetic. That means nothing here tells you how much soil to strip so the finished lawn meets a path, a drive or an edging flush rather than standing proud of it, nor how deep the graded bed underneath needs to be. Order the topsoil, the grading and the levelling as separate quantities, and settle the finished level before the delivery arrives rather than after.
