Sod Calculator

Convert a lawn's area into sod rolls and pallets, with a waste allowance for trimming around edges, using the standard 10 square foot roll and a pallet that covers 400 to 500 square feet.

Measure the area you are actually covering, then add waste for curves and obstacles. Sod is perishable: it needs to go down within about 24 hours of delivery.

Formula

Area = length × width (rect), π × (diameter ÷ 2)² (circle), or ½ × base × height (triangle) · Total = area × (1 + waste%) · Rolls = ⌈total ÷ 10⌉ · Pallets = total ÷ 450

How sod is actually sold

Sod is sold by the roll and delivered by the pallet, and neither number is standardised across suppliers. The common residential roll is 2 feet by 5 feet, 10 square feet. Some farms cut smaller slabs of roughly 2.7 square feet, which changes the piece count but not the total area you need.

A pallet covers 400 to 500 square feet depending on the grower and the grass. That is 40 to 50 of the 10-square-foot rolls. Always confirm the pallet coverage with your supplier before ordering, because the difference between a 400 and a 500 square foot pallet is a whole extra pallet on a large lawn.

Rolls on the bottom of a pallet can look compressed. They expand to their true size once unrolled and watered, so do not assume the stack is short.

How much waste allowance?

Lawn shapeSuggested wasteWhy
Simple rectangle, few obstacles5%A little trimming at the edges
Rectangle with beds, paths, a tree10%Cuts around every obstacle
Curved or irregular border15%Every curve produces offcuts that cannot be reused

Waste is not optional with sod. The offcuts from a curve are the wrong shape for anything else on the lawn, and unlike tile you cannot put them back on the pallet and return them, sod dies within about 48 hours of being cut.

Before you lay it

Sod needs contact with soil, not with rubble. Strip the old surface, rotovate or rake the top two inches, firm it and water it before the sod goes down. Then water daily for the first week or two, tapering off as the roots knit into the soil beneath. Keep the pallets in shade and damp if you cannot lay them the same day.

Cool-season grasses such as Kentucky bluegrass, tall fescue and perennial ryegrass prefer 60–75°F. Warm-season grasses such as Bermuda, zoysia and St Augustine prefer 80–95°F. Laying a warm-season sod in cold weather stalls the roots, and the lawn never fully knits.

Where these rules come from

The 10 square foot roll (2 ft × 5 ft), the 400–500 square foot pallet range and the 5–15% trimming allowance are the figures published by sod growers and landscaping estimators. Pallet coverage varies by supplier and grass variety, so the calculator's pallet line is an estimate: confirm the actual coverage per pallet before ordering.

Frequently Asked Questions

How do I calculate how much sod I need?

Measure the lawn area in square feet, add 5–15% for trimming waste, then divide by the roll size. A 1,500 sq ft lawn with 5% waste needs 1,575 sq ft of sod, which is 158 rolls at 10 square feet each, about 3.5 pallets.

How big is a roll of sod?

The most common residential roll is 2 feet by 5 feet, covering 10 square feet. Some suppliers cut larger rolls around 15 square feet or smaller slabs around 2.7 square feet. The area you need does not change, only the piece count.

How many rolls of sod are on a pallet?

A pallet covers 400 to 500 square feet, so with 10 square foot rolls that is roughly 40 to 50 rolls. Confirm the pallet coverage with your supplier, the range is genuinely that wide between growers.

How soon do I need to lay sod after delivery?

Within 24 hours, and the same day if possible. Sod on a pallet heats up and starts to deteriorate quickly; in hot weather aim for 12 hours. Keep it shaded and moisten it if you cannot lay it immediately.

Should I add waste to my sod order?

Yes. Use about 5% for a simple rectangle, 10% for a lawn with beds and paths, and 15% for curved or irregular borders. Sod offcuts cannot be stored and reused the way tile can, because the grass dies within about 48 hours of being cut.
