How Do You Measure a Lawn for Sod?
Measure a lawn for sod by splitting it into rectangles, circles and triangles, measuring each in feet, and adding their areas. Subtract patios, beds and driveways, then add 5 to 10% for cutting waste. The total is the square footage of sod to order.
A 100-foot tape or a measuring wheel gives the most accurate lawn size; pacing works for a rough first estimate at about 2.5 feet per normal step. Measure to the edge where sod will stop — along walkways, fences and bed edging — rather than to the property line. The calculator above works as a lawn size calculator: each section can be a rectangle, circle, triangle, L-shape or a known area, and cut-outs are subtracted automatically.
| Shape | Area formula | Example |
|---|---|---|
| Rectangle or square | length × width | 40 × 25 ft = 1,000 sq ft |
| Circle | 3.1416 × radius² | 20 ft across = 314 sq ft |
| Triangle | ½ × base × height | 30 ft base, 20 ft high = 300 sq ft |
| L-shape | overall rectangle − missing corner | 50 × 40 − 20 × 15 = 1,700 sq ft |
Measure in feet for square feet, or in meters for square meters. 1 m² = 10.76 sq ft.
Curved lawns are easiest to approximate with a few overlapping rectangles and a circle or two. Straight-edged lawns need about 5% extra sod; lawns with curved beds, tree rings and many corners need 8 to 10%, because every curve means trimming pieces.
How Much Sod Is on a Pallet?
A pallet of sod typically covers 400 to 500 square feet, often 450 sq ft. That equals about 169 slabs of 16 × 24 inches or 45 rolls of 2 × 5 feet. Pallet size varies by farm, so set your supplier's figure in the calculator.
Sod comes in three main formats. Slabs — small rectangles around 16 × 24 inches — are common in the South for St. Augustinegrass and zoysiagrass. Small rolls of about 2 × 5 feet (10 sq ft) are standard for Kentucky bluegrass, tall fescue and bermudagrass. Big rolls, often 30 to 48 inches wide and many feet long, cover large lawns with fewer seams but need machinery to lay.
| Piece size | Covers | Per 400 sq ft pallet | Per 450 sq ft pallet | Per 500 sq ft pallet |
|---|---|---|---|---|
| 16 × 24 in slab (41 × 61 cm) | 2.67 sq ft (0.25 m²) | about 150 | about 169 | about 188 |
| 18 × 24 in slab (46 × 61 cm) | 3 sq ft (0.28 m²) | about 133 | about 150 | about 167 |
| 2 × 5 ft roll (0.6 × 1.5 m) | 10 sq ft (0.93 m²) | about 40 | about 45 | about 50 |
Pieces per pallet = pallet square footage ÷ area of one piece. Actual counts vary by farm.
Most suppliers sell full pallets, and many also sell loose pieces. When the order is just over a whole number of pallets, the calculator shows the split — for example 5 full pallets plus 23 loose rolls instead of a sixth pallet that would mostly go to waste.
How Much Does a Pallet of Sod Weigh?
A pallet of sod typically weighs about 1,500 to 3,000 lb (680–1,360 kg), or roughly 3.5 to 6.5 lb per square foot. A single 2 × 5 ft roll weighs about 35 to 65 lb, and a 16 × 24 in slab about 9 to 17 lb, depending on moisture and soil.
Sod weight depends mostly on the soil attached to the roots and on how recently the field was irrigated or rained on. Clay-based sod and freshly watered sod sit at the top of the range; sandy, well-drained sod at the bottom. The 2,474 sq ft example above weighs about 12,400 lb — roughly 6 US tons — at 5 lb per square foot.
Many half-ton pickups are rated for roughly 1,500 to 2,000 lb of payload, so a single heavy pallet can overload one. Farm or garden-center delivery with a forklift or pallet jack drops pallets close to the lawn, which saves carrying hundreds of heavy pieces. Ask the supplier to place pallets on the driveway or a hard surface in shade, never on the lawn area you are about to sod.
Is Sod Better Than Grass Seed?
Sod gives an instant, weed-free lawn that controls erosion and can take light use in about 2 to 4 weeks, but it costs several times more than seed. Grass seed is cheaper and offers more grass varieties, but needs 6 to 10 weeks and careful watering to establish.
| Sod | Grass seed | |
|---|---|---|
| Upfront cost | Several times higher per sq ft | Lowest cost per sq ft |
| Time to a usable lawn | About 2–4 weeks for light use | About 6–10 weeks; a full season to thicken |
| Slopes and erosion | Holds soil immediately | Seed can wash away before rooting |
| Weeds | Starts weed-free | Weeds compete while seedlings establish |
| Grass choice | Limited to what local farms grow | Wide choice of blends, incl. shade mixes |
| Planting window | Wider — any time turf is actively growing | Narrower — tied to soil temperature |
Sod suits slopes, high-traffic family lawns and projects that need a finished look quickly, such as a new home or a lawn before a sale. Seed suits large areas, tight budgets, shady lawns that need a specialty blend and thin lawns that only need thickening. For a seeded lawn, the grass seed calculator for new lawns and overseeding converts the same lawn measurements into pounds of seed by grass type.
When Is the Best Time to Lay Sod?
The best time to lay sod is when the grass is actively growing: early fall or spring for cool-season grasses such as Kentucky bluegrass and tall fescue, and late spring to early summer for warm-season grasses such as bermudagrass, zoysiagrass and St. Augustinegrass.
Cool-season sod roots fastest in the mild air and warm soil of early fall, with spring a close second; summer installs work with generous watering but stress the turf. Warm-season sod roots best once soil has warmed in late spring and before the heat of midsummer; it can be laid while dormant, but roots slowly until spring green-up. Sod can go down in almost any season as long as the ground isn't frozen and water is available, which gives it a wider planting window than seed.
How Do You Prepare Soil and Lay Sod?
Prepare for sod by removing old grass and weeds, loosening the top 4 to 6 inches of soil, grading it away from buildings and raking it smooth about 1 inch below paths. Lay sod the day it arrives, in a staggered brick pattern with tight seams, then roll and water it.
Poor or compacted ground benefits from 4 to 6 inches of screened topsoil, and a topsoil calculator in cubic yards sizes that load from the same lawn area. A soil test shows whether the ground needs lime, sulfur or phosphorus; a starter fertilizer raked in before laying supports root growth, and a fertilizer calculator for lawn nitrogen rates converts the label's N-P-K into pounds per lawn.
Start the first row along a straight edge such as a driveway or a string line. Butt each piece tightly against the next without overlapping or stretching, stagger the joints like bricks, and cut pieces with a sharp knife around curves and beds. On slopes, lay rows across the slope and pin pieces with sod staples. Roll the finished lawn with a half-full lawn roller to press roots into contact with the soil, and start watering within about 30 minutes of laying each section.
How Often Should You Water New Sod?
New sod typically needs daily watering for the first 1 to 2 weeks, enough to keep the sod and the top inch or two of soil beneath it moist. Water less often but more deeply as roots knit in, moving to about 1 inch per week after 3 to 4 weeks.
The first watering should soak through the sod into the soil below — lift a corner to check that the soil is wet. In hot, windy weather new sod may need two short waterings a day, while cool, cloudy weather needs less; edges and areas near pavement dry out first. When a gentle tug no longer lifts a piece, roots have anchored and watering can taper to deeper sessions every few days. Hold off mowing until the sod is rooted, usually 2 to 3 weeks, and keep heavy traffic off for about a month. Local watering restrictions and the supplier's instructions take priority.

Frequently Asked Questions
- How many square feet are in a pallet of sod?
- A pallet of sod usually covers 400 to 500 square feet, and 450 sq ft is a common size. Coverage varies by sod farm, grass type and piece size, so confirm the square footage per pallet with your supplier before ordering.
- How many pieces of sod are on a pallet?
- A 450 sq ft pallet holds about 169 slabs of 16 × 24 inches or 45 rolls of 2 × 5 feet. Divide the pallet's square footage by the area of one piece — 2.67 sq ft for a 16 × 24 in slab, 10 sq ft for a 2 × 5 ft roll.
- How much extra sod should I order?
- Order about 5% extra for simple rectangular lawns and 8 to 10% for curved edges, many beds or tree rings. The extra covers pieces cut to fit, broken corners and the odd damaged roll.
- How long can sod stay on the pallet?
- Sod is best laid the day it arrives and generally within about 24 hours. Stacked sod heats up and yellows quickly in warm weather, so keep pallets in shade and lay the pieces as soon as possible.
- Can you lay new sod over existing grass?
- Laying sod over existing grass is not recommended. The old turf keeps the new roots from reaching the soil and decays unevenly underneath, which leaves bumps and dry spots. Remove the old grass and loosen the soil first.
