CloudCalcAppSod Calculator
Estimate how much sod you need for a lawn - enter the area to get the square feet and square yards to order, with a waste allowance you control plus roll, piece, and pallet estimates.
A sod calculator works out how much turf to order for a lawn. It is an area calculation, not a volume one — sod is laid one piece thick, so there is no depth. Measure the lawn in feet (or enter an area you already have), add a few percent for cutting waste, then divide by 9 to get square yards, the unit most sod is sold in.
Extension guidance on the waste allowance differs: about 5% for a simple rectangular lawn (Mississippi State University Extension), about 10% for a lawn with many curves and cut edges (Purdue Extension), and up to 15% for a very irregular lawn. The calculator does not add any of these for you — enter the figure that fits your lawn. Sod comes in slabs and rolls of different sizes, and pallet coverage is not standardized — it runs roughly 400–700 sq ft depending on the grass and region, so confirm it with your supplier (and enter it for an exact pallet count). Measuring a curved or irregular lawn? Work it out in the Square Footage Calculator first, then choose “Known area” here. Before laying sod, prepare and amend the soil — see the Topsoil Calculator.

Sod Calculator Examples
500 sq ft courtyard lawn
- Area type:
- Known area
- Area:
- 500 sq ft
- Waste:
- 5%
500 x 1.05 = 525 sq ft to order, which is 525 / 9 = 59 square yards. As a rough guide that is about 197 Southern slabs (2.67 sq ft) or 53 large rolls (10 sq ft), roughly 1 to 2 pallets depending on the pallet size your supplier uses.
1,000 sq ft front lawn
- Area type:
- Known area
- Area:
- 1,000 sq ft
- Waste:
- 10%
1,000 x 1.10 = 1,100 sq ft to order, or 1,100 / 9 = 123 square yards. That works out to roughly 2 to 3 pallets - pallets run from about 400 sq ft (warm-season) to 700 sq ft (cool-season), so confirm the figure with your supplier.
30 ft x 50 ft back lawn
- Area type:
- Rectangular area
- Length:
- 30 ft
- Width:
- 50 ft
- Waste:
- 10%
30 x 50 = 1,500 sq ft. Adding 10% for cutting waste brings it to 1,650 sq ft to order, which is 1,650 / 9 = 184 square yards.
Irregular lawn measured as a known area
- Area type:
- Known area
- Area:
- 2,240 sq ft
- Waste:
- 15%
Work out a curved lawn in the Square Footage Calculator first - say 2,240 sq ft - then enter that total under 'Known area'. At 15% for the extra cuts an irregular shape needs, 2,240 x 1.15 = 2,576 sq ft to order, or 2,576 / 9 = 287 square yards.
Large lawn with a known pallet size
- Area type:
- Known area
- Area:
- 8,000 sq ft
- Waste:
- 10%
- Pallet coverage:
- 450 sq ft
8,000 x 1.10 = 8,800 sq ft to order, which is 8,800 / 9 = 978 square yards. Entering the supplier's 450 sq ft pallet coverage gives an exact 8,800 / 450 = 20 pallets.
FAQ
How much sod do I need?
Take the lawn's length times its width for the area in square feet, or enter an area you already worked out. Divide by 9 to get square yards, the unit sod is usually sold in, then add a few percent for cutting waste. The calculator above also returns an approximate piece count and a pallet estimate.
How do I calculate sod for my lawn?
Purdue Extension describes it in three steps: find the total square footage of the lawn, divide by 9 to convert to square yards because vendors typically sell sod by the square yard, then add about 10 percent to cover calculation errors and the waste from cutting sod around corners and edges. For a 3,779 square foot lawn that is 420 square yards plus 42, so about 462 square yards.
How many square feet are in a pallet of sod?
There is no standard. Mississippi State University Extension says a pallet typically contains 450 to 500 square feet. Across the industry pallets run roughly 400 to 700 square feet: warm-season slabs are cut thick with more soil attached, so a pallet often covers about 400 square feet, while lighter cool-season rolls can reach 500 to 700 square feet before the pallet gets too heavy to handle. Always confirm the coverage with your supplier and enter it above for an exact pallet count.
How many rolls or pieces of sod do I need?
It depends on the format. A Southern slab measures about 16 by 24 inches and covers 2.67 square feet, so it takes about 188 to cover 500 square feet. A mini hand roll covers about 5 square feet (100 per 500 square feet) and a large roll covers about 10 square feet (50 per 500 square feet). Divide your square footage to order by the coverage of the format your supplier stocks.
How much extra sod should I order?
Guidance varies. Mississippi State University Extension suggests buying about 5 percent more than you think you need. Purdue Extension recommends about 10 percent to cover miscalculations and the waste from cutting around corners and edges. For a lawn with many beds, trees, and curves, up to 15 percent is reasonable. This calculator applies none of these automatically - set the figure that matches your lawn in the optional waste field.
How do I calculate sod for an irregular or curved lawn?
Break the lawn into rectangles, triangles, and circles, work out each area, and add them together - the Square Footage Calculator does this and supports every shape. Then come back here, choose 'Known area', and enter the total. Because irregular shapes waste more sod at the edges, use a higher waste percentage, around 15 percent.
Should I prepare the soil before laying sod?
Yes. Sod needs firm, graded soil with the top few inches loosened and, on poor sites, topsoil or compost mixed into the upper 6 to 8 inches (Purdue Extension). Do this before the sod is delivered, since sod should be laid within a day or so of harvest. Use the Topsoil Calculator to estimate how much topsoil or compost you need for the bed.
Is sod sold by the square foot or the square yard?
Most sod is priced and sold by the square yard, and one square yard equals 9 square feet (Mississippi State University Extension). Suppliers still quote pallet coverage in square feet, so it helps to know both numbers. This calculator reports the amount to order in square feet and in square yards.
