Sod Calculator
Sod Calculator
Estimate sod for lawns and landscaping by splitting your project into zones, selecting a shape for each zone, and adding a waste factor. The calculator also estimates rolls/pallets using standard sod sizes, plus optional topsoil volume and total cost in USD.

Standard sod sizes
Sod is commonly sold as rolls/slabs and bundled on pallets. Select the preset that matches your supplier.
| Region | Roll size | Roll area | Rolls/pallet | Pallet area |
|---|---|---|---|---|
| US Standard | 2′ × 5′ | 10 ft² | 50 | 500 ft² |
| US Slab | 16″ × 24″ | 2.67 ft² | 180 | 480 ft² |
| US Big Roll | 4′ × 50′ | 200 ft² | 5 | 1,000 ft² |
| Metric | 0.5 m × 1 m | 0.5 m² | 100 | 50 m² |
Step-by-step formulas
1. Calculate area by shape
Measure each lawn section (zone) and choose the matching shape. If your lawn is irregular, break it into multiple simple zones and add them together.
2. Add a waste allowance
Waste accounts for trimming, curves, obstacles, and small measurement errors. This calculator uses a waste slider from 5–15% (10% default).
3. Estimate rolls or pallets (optional)
Select a standard sod size preset to estimate rolls needed. The calculator also estimates full pallets plus remaining loose rolls.
4. Estimate cost (optional)
Enter a price per pallet and a price per loose roll to estimate total cost in USD. Delivery, installation, and soil prep are typically separate.
5. Topsoil volume (optional)
If you plan to topdress or build up the lawn, enter a topsoil depth to estimate volume. In imperial units, depth is in inches; in metric, depth is in centimetres.
Examples
Example 1: Rectangular lawn (feet)
A 40 ft × 25 ft lawn with 10% waste.
Aₒᵣdₑᵣ = 1,000 × 1.10 = 1,100 ft²
Example 2: Two-zone (L-shape) lawn
Split an L-shape into two rectangles: Zone 1 is 20 × 12 and Zone 2 is 10 × 8 (same units). Add areas, then apply waste.
Aₒᵣdₑᵣ = 320 × (1 + Waste%)
Example 3: Circular area (meters)
A circular lawn with diameter 12 m and 10% waste.
Aₒᵣdₑᵣ ≈ 113.10 × 1.10 ≈ 124.41 m²
Pro tips for ordering sod
- Measure the largest rectangle and subtract cutouts if needed (beds, patios, pools).
- Order a little extra to match dye lot / batch and avoid delayed patching.
- Confirm coverage per pallet/roll with your supplier before ordering.
- If your lawn is an L-shape or complex, split it into zones and add them.
- Schedule delivery close to installation time — sod is a perishable product.
Ordering and Laying Sod
Sod is a living product on a countdown from the moment it is cut, which shapes how you order it:
- Instant Established Lawn: Sod gives a usable lawn immediately and roots within a few weeks, against months for seed. It also suppresses weeds and resists erosion on slopes from day one.
- Pallets Are the Order Unit: Sod ships by the pallet, typically covering 400–500 ft². Converting area to whole pallets is what the supplier actually quotes and delivers.
- It Deteriorates on the Pallet: Stacked sod heats internally and can yellow or die within 24–48 hours, faster in summer. Schedule delivery for the morning you intend to lay it, not before.
Benefits of Using This Calculator
Example Calculations
Three scenarios worked through step by step:
Example 1 — Rectangular Back Lawn
Lawn 60 ft × 40 ft, slabs 2.67 ft², 450 ft² per pallet, 5% waste.
Area = 60 × 40 = 2,400 ft²
With 5% waste = 2,520 ft²
Slabs = 2,520 ÷ 2.67 = 944 slabs
Pallets = 2,520 ÷ 450 = 5.6 → 6 pallets
At $180/pallet = $1,080
Example 2 — Lawn With Curved Beds
Lawn 2,000 ft² after deducting beds, 10% waste for curves.
With 10% waste = 2,000 × 1.10 = 2,200 ft²
Pallets = 2,200 ÷ 450 = 4.9 → 5 pallets
Curved edges generate more offcuts than straight
Result: 5 pallets, about 250 ft² spare
Example 3 — Front Yard Split by a Path
Two areas: 30 × 20 ft and 25 × 14 ft, 8% waste.
Area 1 = 600 ft²; Area 2 = 350 ft²
Total = 950 ft²
With 8% waste = 1,026 ft²
Pallets = 1,026 ÷ 450 = 2.28 → 3 pallets
Result: 3 pallets covers both sections
Installation Tip
Installation Tip
Book delivery for the morning you plan to lay, and water each section within half an hour of placing it rather than waiting until the whole lawn is down. Sod roots from the soil moisture beneath it, and a slab that dries at the edges shrinks, leaving gaps that never fully close.
FAQs
- How much extra sod should I order for waste?
- This calculator uses a waste range of 5–15% (10% default). Use a lower value for simple rectangles and a higher value for curves, tight cuts, and obstacles.
- How do I calculate sod for an irregular or L-shaped lawn?
- Break the lawn into simple sections (zones) like rectangles, triangles, or trapezoids, then add the areas together. The calculator supports multiple zones and an L-shape option as two rectangles.
- Is sod sold by square feet or by pallets?
- Both are common. Many suppliers sell pallets with a fixed number of rolls/slabs. This calculator estimates full pallets plus remaining loose rolls based on the preset roll and pallet coverage.
- Can I estimate topsoil volume for sod installation?
- Yes. Enter an optional topsoil depth to get a volume estimate. In imperial units, depth is in inches; in metric units, depth is in centimetres.
- How much sod do I need?
- Measure the area in square feet, add 5–10% for cuts and curves, then divide by the pallet coverage — usually 400 to 500 ft². A 2,400 ft² lawn with 5% waste needs about six 450 ft² pallets.
- How big is a pallet of sod?
- Typically 400 to 500 square feet, made up of slabs, small rolls, or big rolls depending on the grower. A pallet weighs 1,500 to 3,000 lb depending on moisture, which matters for access and handling on site.
- How long can sod sit on the pallet?
- Twenty-four hours in cool weather and less in summer heat, since stacked sod composts itself from the inside. If you cannot lay it immediately, unstack it in shade and keep it damp, but expect some loss.
- Should I prepare the soil before laying sod?
- Yes — this determines whether the lawn takes. Remove debris, till or loosen the top few inches, grade smooth and slightly below surrounding hard surfaces, and apply a starter fertiliser. Sod laid on compacted ground struggles to root.
- How much does sod cost?
- Roughly $0.35 to $0.85 per square foot for the material, or $130 to $400 per pallet depending on grass type and region. Professional installation including ground preparation typically doubles the material cost.
- How soon can I walk on new sod?
- Keep off it for two weeks other than for essential watering, then light use. Wait three to four weeks before mowing, and only when the slabs resist a gentle tug, which shows roots have knitted into the soil.
