Sod Calculator

How this is calculated

The area is length times width, plus a waste allowance, divided by the coverage of one pallet and rounded UP - you cannot buy part of a pallet. Pallet coverage is an input because it genuinely varies by region and supplier, commonly somewhere between 400 and 500 square feet. Ask before you order rather than assuming, because it is the number the pallet count turns on. Sod is also frequently priced by the square yard, which is why that figure is shown - 9 square feet to the square yard. Ten percent covers a rectangular lawn with straight edges. Curves, island beds, tree rings and awkward corners all push it higher, because every curved edge means cutting a straight piece to fit and the offcuts rarely fit anywhere else. Fifteen to twenty percent is normal for a shaped lawn. ⚠️ THE CONSTRAINT THAT MAKES SOD DIFFERENT: it is alive, harvested to order, and on a clock. It is typically cut within a day of delivery and should be laid within about 24 hours in mild weather - considerably less in heat, where a stacked pallet will start composting in the middle from its own warmth. That single fact inverts the usual advice about buying extra. With tile or flooring, a spare box is cheap insurance. With sod, material you cannot lay today is material that may be dead tomorrow, so the sensible margin is smaller and the sensible plan is to have the ground fully prepared BEFORE the delivery arrives rather than after. The ground preparation is also where the real work is, and none of it is in this calculation: clearing, grading so water runs away from buildings, tilling, and any soil amendment. Sod laid on unprepared ground fails in a way that is expensive and entirely visible. This assumes one rectangle. Measure an irregular lawn as several rectangles and add the areas before applying waste.

Common questions

Why shouldn't I order a spare pallet?

Because sod is alive and on a clock, which no other landscaping material is. It is harvested to order, usually cut within a day of delivery, and should be laid within about 24 hours in mild weather - considerably less in heat, where a stacked pallet begins composting in the middle from its own warmth. Spare tile keeps for years. Spare sod is a pallet of dying grass and a disposal problem, so the honest margin here is smaller than you would use for anything else.

How much waste should I allow?

Ten percent for a rectangular lawn with straight edges. Fifteen to twenty for anything with curves, island beds, tree rings or awkward corners - every curved edge means cutting a straight piece to fit, and unlike a straight offcut the leftover wedge rarely fits anywhere else. If your lawn is mostly curves, budget toward the top of that range.

How big is a pallet?

It varies by region and supplier, commonly between 400 and 500 square feet, which is why it is an input rather than a built-in figure. Ask before you order. Bear in mind a full pallet weighs a great deal - sod is heavy, and heavier still if it has rained - so access for the delivery and a plan for moving it are worth thinking about before it arrives.

Should I measure an irregular lawn as one shape?

No - break it into rectangles, work out each, and add the areas before applying the waste allowance. Measuring the overall bounding box of an L-shaped lawn includes ground that is not lawn, and you will pay for grass to cover a flower bed. Circles and curves are best handled by measuring the rectangle that contains them and letting the waste allowance absorb the difference.

What should I do before it arrives?

Everything. The ground preparation is the real work and none of it is in this calculation - clearing, grading so water runs away from buildings, tilling, and any soil amendment. Because sod is on a clock, the preparation has to be finished BEFORE the delivery, not started after it. Sod laid on unprepared ground fails in a way that is both expensive and completely visible.

Is sod better than seed?

Different trade-offs rather than better. Sod is an instant lawn, can be laid across a wider window, and resists erosion immediately - which matters on a slope. It costs considerably more per square foot and needs heavy, consistent watering to root. Seed is far cheaper and gives deeper root establishment over time, but takes weeks to look like anything and is vulnerable to rain, birds and being walked on.

Copy this into ChatGPT or Claude with your own numbers filled in. It hands over the figures this calculator worked out, so the answer is built on real arithmetic instead of a guess.

What I entered:
- Lawn length (ft): ___
- Lawn width (ft): ___
- Waste allowance (%): ___
- Coverage per pallet (sq ft): ___

What it calculated:
- Pallets to order: ___
- Lawn area: ___

Use those figures as given — they are already worked out, so please don't recalculate or estimate your own. Help me turn them into a plan: what to buy or do, in what order, roughly what it should cost, and the mistakes people most often make with this job.
