Sod Calculator

Rolls and pallets of sod for a lawn area.

Your measurements

A standard slab covers about 10 sq ft. Big rolls cover far more.

Sod is cut to fit, so 5–10% covers the trimming around edges and beds.

Order sod for the day you intend to lay it. It is a living product that heats up on the pallet and can be dead within 48 hours in warm weather, so a delivery that waits for the weekend is a delivery you pay for twice.

The ground needs preparing before the sod arrives — cleared, levelled, and ideally with a starter fertiliser worked in. That work cannot happen after the pallet is on the drive.

Water deeply and immediately after laying, then keep it damp for the first two weeks. Sod that dries out at the seams shrinks and leaves permanent gaps.

Enter the lawn dimensions and the coverage of the sod you are buying, and it returns rolls and an approximate pallet count. Sod is a living product on a deadline, so the ordering advice matters as much as the quantity.

Why use this tool?

Rolls and pallets

Rolls are how sod is counted, pallets are how it is delivered. Both figures let you order without converting.

Any slab or roll size

Standard slabs cover about 10 sq ft, big rolls far more. Enter what your supplier sells.

Trimming allowance

Sod is cut to fit rather than laid in whole units, so 5–10% covers the edges and curves.

Timing guidance built in

The result explains why the delivery date and the laying date have to be the same day.

How this sod calculator works

Area times the waste allowance, divided by the coverage of one roll, rounded up. Pallets follow at roughly 450 square feet each, which is the common figure though it varies by supplier and sod type.

The waste allowance is lower than for most materials because sod is cut with a knife to fit any shape, and the offcuts from one edge often fill a gap elsewhere. Five to ten per cent covers curved beds and awkward corners.

What the arithmetic cannot tell you is that sod is perishable. It is harvested, rolled and stacked, and it begins heating on the pallet immediately — which is why the delivery and installation have to happen together.

How to use it

  1. Step 1: Measure the lawn

    Length and width of the area to be turfed. For irregular shapes, break it into rectangles and add the areas.

  2. Step 2: Check the roll coverage

    Ask the supplier what one slab or roll covers. Standard slabs are around 10 square feet; big rolls can be 50 or more.

  3. Step 3: Prepare the ground first

    Clear, level and rake the soil before the delivery arrives. This work cannot happen with a pallet of sod waiting on the drive.

  4. Step 4: Order for the day you lay it

    Book the delivery for the morning you intend to install, not for whenever is convenient.

Example usage

A 40 by 25 back lawn
1,000 square feet plus 8% is 1,080, which is 108 standard rolls or about 3 pallets. That is a full day's work for two people.
A small front lawn
A 20 by 15 area is 300 square feet, 324 with waste, or 33 rolls — under a pallet, and often available for collection rather than delivery.
A lawn with curved beds
Curves waste more than rectangles. Measure the containing rectangle and keep the 8% allowance rather than trying to subtract the bed shapes — the offcuts around a curve are rarely reusable.

Frequently asked questions

How much sod do I need?

Your lawn area plus 5 to 10 per cent for trimming, divided by the coverage of one roll. A 1,000 square foot lawn typically needs about 108 standard 10 square foot rolls, or roughly 3 pallets.

How many square feet are on a pallet of sod?

Around 450 square feet is the common figure, though it varies by supplier, sod type and slab size. Confirm with your supplier before ordering, since a wrong assumption compounds across several pallets.

How long can sod sit before it is laid?

Not long. It begins heating on the pallet immediately and can be dead within 48 hours in warm weather — often sooner. Order it for the day you intend to lay it, and lay it that day.

Do I need to prepare the soil first?

Yes, and before the delivery arrives. The ground needs clearing, levelling and ideally a starter fertiliser worked in. Sod laid on unprepared ground roots badly and shows every bump permanently.

How much should I water new sod?

Deeply and immediately after laying, then keep it consistently damp for the first two weeks while it roots. Sod that dries at the seams shrinks and leaves gaps that never fully close.
