Calculate how much sod you need in square feet, rolls, and pallets, plus the total cost, from your lawn’s measurements.
Sod Formula
The base calculation finds the area you need to cover, then converts that area into rolls, pallets, and cost. Start by finding the area of the space.
Area = Length * Width
Add a waste factor so you order enough to cover cuts, curves, and damaged pieces.
SodNeeded = Area * (1 + Waste)
Convert the sod needed into rolls and pallets by dividing by how much each one covers, then round up to whole units.
Rolls = SodNeeded / RollCoverage
Pallets = SodNeeded / PalletCoverage
To estimate cost, multiply the sod needed by the price per square foot, or multiply the number of rolls or pallets by their unit price.
Cost = SodNeeded * PricePerSqFt
- Area is the surface you want to cover, in square feet.
- Length and Width are the measurements of a rectangular section, converted to feet so the area comes out in square feet.
- Waste is the extra fraction added for cuts and irregular edges, usually 5 to 15 percent.
- SodNeeded is the area after waste is added, the amount you actually order.
- RollCoverage is how many square feet one roll covers, commonly about 10 square feet.
- PalletCoverage is how many square feet one pallet covers, commonly about 450 square feet.
- PricePerSqFt is the price of sod for one square foot.
The "how much sod I need" mode takes your shape and measurements, adds the waste factor, and reports the area in square feet along with the number of rolls and pallets to buy. The "estimated sod cost" mode does the same and multiplies by the price you enter, whether that price is per square foot, per roll, or per pallet. The "coverage of sod I already have" mode works backward: you enter how many rolls, pallets, or square feet you own, and it tells you how large an area that will cover. The shape selector lets you measure a rectangle, several sections, a circle, or a triangle, or enter a total area you already know.
Sod Coverage and Cost Reference
Use this table to sanity check the rolls, pallets, and cost the calculator returns. Coverage and price vary by grass type and supplier, so confirm the numbers with your seller before ordering.
| Unit | Typical Coverage | Typical Cost |
|---|---|---|
| One roll (2 ft x 5 ft) | About 10 sq ft | $3 to $8 |
| One pallet | 400 to 600 sq ft (450 common) | $150 to $450 |
| Per square foot | 1 sq ft | $0.35 to $1.00 |
Warm-season grasses like Bermuda and St. Augustine often come on 400 to 450 square foot pallets, while cool-season grasses in the north can cover 500 to 600 square feet per pallet.
Choosing a Waste Factor
| Yard Shape | Suggested Waste |
|---|---|
| Simple square or rectangle | 5 percent |
| Some curves or a few obstacles | 10 percent |
| Many curves, beds, or odd angles | 15 percent |
Example Problems
Example 1. You have a rectangular lawn that is 40 feet long and 30 feet wide, and you want a 10 percent waste factor. The area is 40 times 30, which is 1,200 square feet. Adding 10 percent gives 1,320 square feet of sod needed. At 450 square feet per pallet, that is 1,320 divided by 450, or 2.93, which rounds up to 3 pallets.
Example 2. You bought 2 pallets of sod and want to know how much area they cover. At 450 square feet per pallet, 2 pallets cover 2 times 450, or 900 square feet. With a 10 percent waste allowance, plan on sodding about 818 square feet of actual lawn so you have enough left over for cuts.
FAQ
How many square feet does a pallet of sod cover? A standard pallet covers about 450 square feet, which is the figure used by Turfgrass Producers International. Real pallets range from roughly 400 square feet for many warm-season grasses to 500 or 600 square feet for cool-season grasses, so always check with your supplier.
How much extra sod should I order? Add 5 percent for a simple rectangular yard, 10 percent for a yard with some curves or obstacles, and up to 15 percent for very irregular shapes. The waste factor covers the pieces you trim off at edges and around beds, which cannot always be reused.
Should I measure in feet or yards? Either works as long as the calculator knows which unit you used. The tool converts your measurements to square feet internally, so a 30 foot by 40 foot lawn and a 10 yard by 13.3 yard lawn give the same result. Pick the unit that matches your tape measure to avoid mistakes.
