Sod Calculator
Find out exactly how much sod to order for your lawn. Enter the area, pick a grass type, and get the square footage, rolls, pallets, and an optional cost breakdown, all with a built-in waste allowance.
Formula
Worked example
A 40 ft x 25 ft Bermuda lawn is 1,000 sq ft. With a 10% waste allowance: 1,000 x 1.10 = 1,100 sq ft of sod. At 10 sq ft per slab that is ceil(1,100/10) = 110 slabs, and at 50 slabs per pallet, ceil(110/50) = 3 pallets. At $0.64/sq ft material cost: 1,100 x $0.64 = $704.
How to calculate how much sod you need
Sod is sold by area, so the starting point is the square footage of the ground you want to cover. Multiply the length by the width of each section, then add the pieces for an irregular yard. You can also switch the calculator to "total area" mode if you already have a measurement from a landscape plan. Once you have the bare area, add a waste allowance: a percentage of extra turf to absorb the trimming, off-cuts, and overlaps that are unavoidable when fitting flat rectangles of sod around curves, beds, and paths. The calculator converts that adjusted area into whole rolls or slabs, then into the number of pallets to order.
Choosing a grass type and estimating cost
The grass type you choose affects both the visual result and your budget significantly. Warm-season grasses like Bermuda ($0.44-$0.83/sq ft), Zoysia ($0.47-$0.72/sq ft), St. Augustine ($0.41-$0.86/sq ft), Centipede ($0.78-$0.85/sq ft), and Bahia ($0.20-$0.33/sq ft) thrive in the South and Southwest and go dormant in winter. Cool-season grasses including Kentucky Bluegrass ($0.29-$0.43/sq ft), Tall Fescue ($0.32-$0.67/sq ft), and Ryegrass ($0.28-$0.58/sq ft) stay green through northern winters. Selecting a grass type pre-fills a typical mid-range material price; you can override it with a quote from your local sod farm. Turn on the cost estimate toggle to add optional labor ($0.55-$1.00/sq ft) and soil preparation ($0.40-$0.90/sq ft) lines to the total.
Rolls, slabs, and pallets
Residential sod usually comes as hand-sized slabs of roughly ten square feet, stacked fifty to seventy-five to a pallet so one pallet covers about 450 to 700 square feet. Large rolls used on commercial jobs can cover far more per piece, so always confirm the exact coverage with your supplier before ordering. Because suppliers sell by the full pallet or the whole roll rather than the square foot, the calculator rounds rolls and pallets up to the next whole unit. You will have a little left over, which is useful for patching thin spots once the lawn is established. Buying by the pallet also tends to be 10-20% cheaper per square foot than purchasing individual rolls.
Waste allowance and site preparation
Almost no lawn is a perfect rectangle, and every cut to fit sod around a flower bed, tree ring, or curved edge leaves a piece that cannot be used elsewhere. A waste allowance of five to ten percent is sensible for a square, open lawn, while irregular shapes, steep slopes, and lots of edging push it toward ten to fifteen percent. Buying a touch extra is far cheaper than running short: sod is perishable, so a second order means a second delivery fee and a fresh batch that may not perfectly match the colour or cut of the first. Before laying, the ground should be tilled and graded so it is level and drains away from the house; adding topsoil or a starter fertiliser helps roots take hold quickly.
Sod cost and climate guide by grass type
| Grass type | Material ($/sq ft) | Climate zone | Season |
|---|---|---|---|
| Bahia | $0.20-$0.33 | Deep South, coastal | Warm |
| Ryegrass | $0.28-$0.58 | Cool-climate or overseeding | Cool |
| Kentucky Bluegrass | $0.29-$0.43 | North, Pacific NW | Cool |
| Tall Fescue | $0.32-$0.67 | Transition zone, North | Cool |
| St. Augustine | $0.41-$0.86 | Southeast, Gulf Coast | Warm |
| Bermuda | $0.44-$0.83 | South, Southwest, sunny | Warm |
| Zoysia | $0.47-$0.72 | Southeast to Mid-Atlantic | Warm/transition |
| Centipede | $0.78-$0.85 | Southeast, acidic soils | Warm |
Material cost only (2026 national averages). Labour typically adds $0.55-$1.00 per sq ft.
Frequently asked questions
How much sod do I need for my lawn?
Measure the length and width of each area in feet (or metres), multiply to get the square footage, and add the pieces for an irregular yard. Then add a waste allowance of 5-15% for trimming. A 40 x 25 ft lawn is 1,000 sq ft, or about 1,100 sq ft of sod with a 10% allowance.
How many pieces of sod are on a pallet?
A pallet of standard residential slabs typically holds 50 to 75 pieces and covers about 450 to 700 square feet, depending on the slab size your supplier cuts. Large-roll sod covers much more per piece, so always confirm the coverage and pallet count before you order. Buying full pallets is usually 10-20% cheaper than ordering loose rolls.
How much extra sod should I buy for waste?
Add about 5% for a square, open lawn and 10-15% for one with curves, beds, slopes, or lots of edging. Every cut to fit a curve leaves an unusable off-cut, and a small surplus lets you patch seams and thin spots instead of placing a costly second order.
What does sod cost per square foot?
Material cost ranges from about $0.20 per sq ft for Bahia up to $0.86 per sq ft for premium St. Augustine, with most grass types falling between $0.30 and $0.75. Professional installation adds another $0.55-$1.00 per sq ft. Soil preparation (tilling, grading, topsoil) can add a further $0.40-$0.90 per sq ft on uneven or compacted ground.
What is the best grass type for my region?
Warm-season grasses (Bermuda, Zoysia, St. Augustine, Centipede, Bahia) suit the South and Southwest, staying green through hot summers but going dormant in winter. Cool-season grasses (Kentucky Bluegrass, Tall Fescue, Ryegrass) thrive in northern states and stay green through cold winters. The transition zone from the Mid-Atlantic to the Midwest can support either, though Fescue and Zoysia are the most common choices there.
When should I lay sod?
For warm-season grasses, late spring through early summer is ideal: soil temperatures above 60 degrees F help roots establish quickly. For cool-season grasses, early fall is best because the cooler air reduces stress while the soil is still warm enough to encourage root growth. Avoid installing sod during extreme heat or when the ground is frozen.
