Sod gives you a finished lawn in a day, but it is perishable: it should be laid within about a day of harvest, so ordering the right amount the first time matters. Sod farms sell by the pallet, and a pallet's coverage depends on the farm and the piece format, commonly somewhere around 400–500 ft² for small rolls or slabs. This sod calculator converts your lawn's dimensions into square feet, adds a small allowance for cuts along beds and paths, and returns the number of pallets and individual rolls or pieces to order.
Extension services such as Mississippi State University's emphasize preparing the soil before sod arrives: grading, removing debris and, where needed, adding topsoil. Use the topsoil calculator for that layer. For a seeded lawn instead, see the grass seed calculator.
How to use the sod calculator
- Measure the area to be sodded. For irregular lawns, total the sections with the square footage calculator and enter the total as length × 1.
- Keep 5% extra for cuts along curves, beds and walkways; use 10% for lawns with lots of edges.
- Enter the size of each roll or slab. Small rolls are often 2 × 5 ft (10 ft²); slabs are commonly 16 × 24 in (about 2.67 ft²).
- Ask your sod farm how many square feet a pallet covers and enter it.
- Enter a price per pallet or per square foot to estimate the cost. Delivery and installation are extra.
Formula
Many farms sell partial pallets or loose rolls; compare the exact pallet figure with the rounded-up number to decide whether a partial pallet makes sense.
Worked example
A 40 × 25 ft backyard lawn with 5% extra, 2 × 5 ft rolls and pallets of 450 ft².
- Lawn area: 40 × 25 = 1,000 ft².
- With 5% extra: 1,000 × 1.05 = 1,050 ft².
- Rolls: 1,050 ÷ 10 = 105 rolls.
- Pallets: 1,050 ÷ 450 = 2.33, so 3 pallets — or 2 full pallets plus about 15 loose rolls if the farm sells them.
Sod sizes and pallet coverage
| Format | Typical size | Area each |
|---|---|---|
| Small roll | 2 × 5 ft | 10 ft² |
| Slab | 16 × 24 in | 2.67 ft² |
| Slab | 18 × 24 in | 3 ft² |
| Big roll (machine-laid) | About 4 ft wide, 40–100+ ft long | Varies |
Sizes vary by farm and grass type. Pallet coverage also varies, and some warm-season grasses are cut thinner and stacked differently from cool-season sod, so always confirm with the supplier.
Laying sod so it roots
University extension guides consistently recommend preparing a smooth, firm seedbed, moistening the soil before laying, staggering the seams like brickwork, pressing pieces tightly together without overlapping, rolling the sod to remove air pockets, and watering thoroughly right after installation. Keep the sod moist until roots knit into the soil, then gradually water less often but more deeply. Avoid heavy foot traffic for the first couple of weeks.
Caveats and assumptions
- Pallet coverage varies by farm and grass type. Always use your supplier's figure.
- Sod is perishable. Schedule delivery for the day you will install, and do not leave it stacked in the sun.
- Steep slopes may need sod staples, and shady areas need a shade-tolerant grass.
- Prices are not included because they vary widely by region, grass species and season.
Frequently asked questions
How many square feet are in a pallet of sod?
It depends on the farm and piece size, but many pallets cover roughly 400–500 ft². Some formats and farms differ, so ask your supplier.
How much sod do I need for 1,000 square feet?
About 1,050 ft² with 5% extra: 105 rolls of 10 ft², or 3 pallets at 450 ft² per pallet.
How many rolls of sod are on a pallet?
Divide the pallet coverage by the roll size. A 450 ft² pallet of 10 ft² rolls holds 45 rolls; a 450 ft² pallet of 16 × 24 in slabs holds about 169 pieces.
How much extra sod should I order?
About 5% for simple rectangular lawns and up to 10% for lawns with many beds, curves and paths.
Do I need topsoil under sod?
If the existing soil is poor, compacted or full of debris, extension services recommend improving it before laying sod. A few inches of quality topsoil, worked in and leveled, helps roots establish.
