Sod gives you a finished lawn in an afternoon, but it is sold in units — square feet, pieces and pallets — that do not always line up with the shape of your yard. This calculator measures the lawn area from a rectangle, circle, triangle or a known total, adds a cutting allowance, and converts the result into the pieces and pallets a sod farm sells. It also estimates the water for the first soaking, which is the most important watering a new lawn gets.
How to use the sod calculator
- Pick the area shape and enter its dimensions, or enter a known area from a plat or the square footage calculator.
- Choose the piece size sold in your area, or enter a custom piece area.
- Enter the coverage per pallet from your supplier.
- Set the extra percentage for cutting along curves and edges.
- Optionally enter the price per pallet.
Sod formulas
Water for an initial 1-inch soaking is 144 in³ ÷ 231 in³ per gallon ≈ 0.62 gallon per square foot.
Worked example: a 50 × 30 ft back yard
Area: 50 × 30 = 1,500 ft². With 5% extra: 1,575 ft².
Pieces of 16 × 24 in (2.67 ft²): 1,575 ÷ 2.67 = 590.6 → 591 pieces.
Pallets of 450 ft²: 1,575 ÷ 450 = 3.5 → 4 pallets, or 3 full pallets plus 87 loose pieces.
First soaking: 1,500 × 0.62 ≈ 935 gallons.
Common sod sizes
| Format | Size | Area each | Typical use |
|---|---|---|---|
| Small slab | 16 × 24 in | 2.67 ft² | St. Augustine, zoysia, centipede |
| Slab | 18 × 24 in | 3 ft² | Many warm-season grasses |
| Roll | 2 × 5 ft | 10 ft² | Bluegrass, tall fescue, Bermuda |
| Big roll | 30–48 in wide, up to 100 ft long | varies | Large lawns, machine installation |
Formats vary by region and farm. Ask your supplier what they cut, how many square feet are on a pallet and whether they sell partial pallets.
Laying sod well
- Schedule delivery for installation day. Sod is a living product that heats up on the pallet. Lay it within a day of harvest, sooner in hot weather.
- Start along a straight edge such as a driveway or walk, and stagger the joints like brickwork.
- Butt pieces tightly without overlapping or stretching them; gaps dry out and leave seams.
- Cut with a sharp knife around beds, trees and curves. These cuts are where the extra percentage goes.
- Roll the lawn with a half-full water roller to press the roots into the soil.
- Water within 30 minutes of laying the first section, then finish the soaking once everything is down.
A pallet of fresh sod often weighs 2,000–3,000 pounds — more than most pickup trucks should carry — so delivery is usually worth it.
Sod or seed?
Sod costs more than seed but gives instant cover, controls erosion on slopes and can be laid during much of the growing season. Seed is far cheaper per square foot and offers a wider choice of grass varieties, but it needs weeks of careful watering. Compare the cost of seeding the same area with the grass seed calculator, and if the soil needs building up first, estimate it with the topsoil calculator.
Frequently asked questions
How much does a pallet of sod cover?
Most sod farms load pallets with 400 to 500 square feet, and 450 ft² is common. Pallet size depends on the grass, the piece size and the farm, so confirm the coverage when you order.
How many pieces of sod are on a pallet?
With 16 × 24 inch slabs (2.67 ft² each), a 450 ft² pallet holds about 168 pieces. Pallets of 2 × 5 ft rolls (10 ft² each) hold about 45 rolls.
How much sod do I need for 1,000 square feet?
Order about 1,050 ft² to allow 5% for cutting around edges and curves — about 2⅓ pallets of 450 ft². Many farms sell partial pallets or extra pieces, so you may not need a third full pallet.
How should I prepare soil before laying sod?
Remove the old turf and weeds, loosen the top few inches of soil, work in compost or topsoil where the soil is poor, then rake and roll it smooth so the finished grade sits about an inch below walks and driveways. Water the soil lightly the day before the sod arrives.
How much water does new sod need?
Soak new sod right after laying with about an inch of water, enough to wet the soil 3–4 inches down. That is roughly 0.62 gallon per square foot. Then keep the sod and soil beneath it moist with daily watering for the first two weeks or so, tapering off as roots take hold.
