Quick Answer
The Sod Calculator estimates how much sod is needed to cover a lawn. It multiplies length by width, adds a 5-10% waste allowance, and converts the result into square feet, slabs (2.67 ft² each), and pallets (~450 ft² each), plus a cost estimate from a price per square foot.
To find how much sod you need, multiply the lawn length by its width in feet, then add about 10% for waste. Divide that area by 2.67 square feet for slabs or by 450 square feet for pallets. A 30 by 20 foot lawn needs about 660 square feet of sod, or two pallets.
Key Takeaways
- Sod area = length × width × (1 + waste%), measured in square feet
- A standard sod slab is 16 in × 24 in = 2.67 ft²; a pallet covers ~450 ft²
- Add 5-10% waste for cuts, curves, and odd-shaped lawns
- Lay sod within 24 hours of delivery — it is a living, perishable product
- Water 2-3 times daily for the first week and keep off the lawn for 2-3 weeks

Formula
Sod Area = Length × Width × (1 + Waste%)
Where:
- A_{sod}=Sod area to order (incl. waste)(ft²)
- L \times W=Measured lawn area(ft²)
- w=Waste allowance for cuts/odd shapes(%)
Worked Examples
Standard Backyard (30 x 20 ft)
A rectangular backyard lawn with a 10% waste allowance at $0.50/ft².
- 1Measured area = 30 ft x 20 ft = 600 ft²
- 2Add 10% waste: 600 x 1.10 = 660 ft²
- 3Slabs = 660 / 2.667 = 247.5 -> 248 slabs
- 4Pallets = 660 / 450 = 1.47 -> 2 pallets
- 5Cost = 660 x $0.50 = $330
Small Front Strip (12 x 9 ft)
A narrow front-yard strip with standard waste.
- 1Measured area = 12 x 9 = 108 ft²
- 2Add 10% waste: 108 x 1.10 = 118.8 ft²
- 3Slabs = 118.8 / 2.667 = 44.6 -> 45 slabs
- 4Pallets = 118.8 / 450 = 0.26 -> 1 pallet (or buy by the slab)
- 5Cost = 118.8 x $0.55 = $65.34
Large Property (80 x 60 ft)
A large open lawn ordered by the pallet at a bulk price.
- 1Measured area = 80 x 60 = 4,800 ft²
- 2Add 8% waste: 4,800 x 1.08 = 5,184 ft²
- 3Pallets = 5,184 / 450 = 11.5 -> 12 pallets
- 4Cost = 5,184 x $0.35 = $1,814.40
Introduction
The Sod Calculator tells you exactly how much sod to buy to cover a lawn — in square feet, slabs, and pallets — plus an instant cost estimate. Just measure your area's length and width, add a small waste allowance for cuts and odd shapes, and the calculator does the rest. A standard sod slab measures 16 in × 24 in (about 2.67 ft²), while a typical pallet covers roughly 450 ft². Ordering the right amount the first time saves money and avoids the rush of laying fresh sod before it dries out. For soil prep underneath, see our potting soil calculator and compost calculator.
How the Sod Calculator Works
The calculator converts your lawn measurements into the quantity of sod to order, accounting for the inevitable waste from cutting pieces to fit.
Measure the length and width of the area in feet
Area = length × width (in square feet)
Add a waste allowance (5-10%) for cuts, curves, and overlaps
Slabs = sod area ÷ 2.667 ft², rounded up to whole slabs
Pallets = sod area ÷ 450 ft², rounded up to whole pallets
Cost = sod area × your price per square foot
For irregular lawns, break the space into rectangles, calculate each one separately, and add the areas together before applying the waste allowance.
Common Sod Sizes and Coverage
Sod is sold in different formats depending on your region and supplier. Knowing the coverage of each helps you order accurately.
| Format | Typical Size | Coverage | Best For |
|---|---|---|---|
| Slab / piece | 16 in x 24 in | 2.67 ft² | Small lawns, patches, hand-carry |
| Small roll | 24 in x 60 in | ~10 ft² | Medium DIY areas |
| Pallet (slabs) | ~168 slabs | ~450 ft² | Whole lawns, bulk pricing |
| Big roll | 24-48 in wide | Varies (large) | Pro installs, sports fields |
Pallet coverage varies by farm from about 400 to 500 ft². Confirm the exact slab count and coverage with your supplier before ordering.
How to Measure Your Lawn for Sod
Accurate measurements are the single biggest factor in ordering the right amount. A few minutes with a tape measure prevents costly over- or under-ordering.
Sketch your yard and divide it into simple rectangles and triangles
Rectangle area = length × width; triangle area = ½ × base × height
For circles, area = 3.14 × radius²
Measure in feet and add the sub-areas together for the total
Subtract large permanent features like patios, beds, and driveways
Always add 5-10% waste once you have the net area
Preparing the Ground Before Laying Sod
Sod only roots well into properly prepared soil. Skipping prep is the most common reason new sod fails.
Remove old grass, weeds, rocks, and debris from the area
Till the top 2-3 inches and grade so water drains away from buildings
Add 1-2 inches of compost or topsoil and rake smooth
Do a soil test and apply a starter fertilizer high in phosphorus
Lightly water the soil so it is moist (not muddy) just before laying
Lay sod within 24 hours of delivery — it is a living, perishable product
Lay sod in a brick-like staggered pattern with tight seams, and roll it after installation to press roots into contact with the soil.
Watering and Aftercare
The first two weeks determine whether your new sod survives. Fresh sod has shallow roots and dries out fast.
Water within 30 minutes of laying the first pieces
Days 1-7: water 2-3 times daily to keep sod and soil consistently moist
Days 8-14: reduce to once daily as roots establish
Week 3 onward: taper to deep, infrequent watering (about 1 inch/week)
Wait until the sod is rooted (cannot be lifted by hand) before the first mow
Keep foot traffic off the new lawn for 2-3 weeks
How Much Does Sod Cost?
Sod pricing varies by grass type, region, and order size. The calculator multiplies your sod area by a price per square foot so you can compare quotes quickly.
Material typically runs $0.30-$0.80 per ft² depending on grass variety
Premium or specialty grasses can exceed $1.00 per ft²
Buying by the full pallet is usually cheaper per ft² than by the slab
Professional installation adds roughly $0.50-$1.50 per ft² in labor
Delivery fees and soil amendments are extra — budget for them separately
Order slightly extra rather than risk a second delivery fee for a few missing pieces

FAQs
How much sod do I need?
Measure your lawn's length and width in feet and multiply them to get the area in square feet, then add 5-10% for waste from cuts and odd shapes. For example, a 30 x 20 ft lawn is 600 ft², or about 660 ft² with 10% waste. Divide by 2.67 ft² to get the number of slabs (about 248) or by 450 ft² to get pallets (2).
What size is a piece of sod?
The most common sod slab in the US measures 16 inches by 24 inches, which equals 2.67 square feet. Sod is also sold in small rolls (around 10 ft²) and large rolls for professional installs. A standard pallet usually holds about 168 slabs and covers roughly 450 square feet, though this varies by farm.
How many square feet does a pallet of sod cover?
A typical pallet of sod covers about 450 square feet, but coverage ranges from roughly 400 to 500 square feet depending on the sod farm and the slab size they use. Always confirm the exact coverage and slab count with your supplier before ordering, especially for large jobs where small differences add up.
How much extra sod should I order for waste?
Add 5% for simple rectangular lawns and up to 10% (or more) for yards with curves, garden beds, trees, and tight corners. The waste covers pieces you cut to fit edges and the occasional damaged slab. It is far cheaper to order a little extra than to pay a second delivery fee for a handful of missing pieces.
How do I measure an irregularly shaped lawn?
Break the area into simple shapes. Use length × width for rectangles, ½ × base × height for triangles, and 3.14 × radius² for circles. Measure each section in feet, calculate its area, and add them all together. Subtract large permanent features like patios and driveways, then add your waste allowance to the net total.
How long can sod sit before it needs to be installed?
Sod is a living, perishable product and should be laid within 24 hours of delivery — sooner in hot weather. Stacked on a pallet, sod heats up and begins to yellow and die within a day or two. Schedule delivery for the same day you plan to install, and prepare the soil before the sod arrives.
How soon can I walk on or mow new sod?
Keep foot traffic off new sod for 2-3 weeks while the roots establish. You can usually mow once the sod is firmly rooted — test by gently tugging a corner; if it resists, it is ready, typically around 2-3 weeks. Mow on a high setting and make sure the lawn is dry enough to avoid tearing.
How much does sod cost?
Sod material typically costs $0.30-$0.80 per square foot, with premium grasses running over $1.00. Professional installation adds roughly $0.50-$1.50 per square foot in labor. Buying full pallets is usually cheaper per square foot than buying individual slabs. Remember to budget separately for delivery, soil amendments, and starter fertilizer.
Is it better to buy sod by the slab or the pallet?
For small patches and repairs, buying by the slab is convenient and avoids leftover waste. For whole lawns, full pallets are almost always cheaper per square foot and ensure color and batch consistency. Use the calculator's pallet figure for large jobs and the slab figure for small ones; if you fall just over a pallet, compare the per-foot cost both ways.
