Sod Calculator
Calculate how much sod you need for your lawn or landscaping project. Enter the dimensions of your area, choose your preferred units, and get results in square feet, square yards, rolls, pallets, and estimated cost — all with a waste factor for accuracy.
What Is a Sod Calculator?
A sod calculator is a tool that helps you estimate the amount of sod (grass turf) needed for your lawn or landscaping project. It calculates the total square footage of the area and determines how many rolls or pallets of sod you need to purchase.
This calculator supports four shapes: Rectangle, Square, Circle, and Triangle and provides results in square feet, square yards, rolls, pallets, and estimated cost.
How Does the Sod Calculator Work?
The calculator uses the following steps:
1. Area Calculation: Based on the selected shape (Rectangle: L×W, Square: s², Circle: π×r², Triangle: ½×b×h)
2. Waste Factor: A waste factor (default 10%) is applied for cuts, seams, and irregular edges.
3. Rolls & Pallets: The total area is divided by the roll size and pallet size to determine how many rolls and pallets you need.
4. Cost Estimation: If you enter a price per roll, the calculator estimates the total material cost.
A standard sod roll covers approximately 2.5 square feet, and a standard pallet covers approximately 450 square feet of sod.

- Roll & Pallet Estimation: Get the number of rolls and pallets needed.
- Waste Factor & Cost: Add a waste factor and estimate total material cost.
- Free & Private: No registration, no data storage.
❓ Sod Calculator FAQ
How do I calculate how much sod I need?
Measure the length and width of the area, multiply to get the square footage, then divide by the size of a sod roll. Add a waste factor of 10% for cuts and seams. This calculator does all the math for you.
What is the formula for calculating sod?
Area = Length × Width. Then Sod Needed = (Area × Waste Factor) ÷ Roll Size. The calculator handles this automatically.
How big is a standard roll of sod?
A standard sod roll is typically 2.5 square feet (about 16 inches × 22 inches). Some suppliers offer larger rolls.
How much sod is on a pallet?
A standard pallet of sod covers about 450 square feet and weighs approximately 1,500-2,000 pounds.
How many square feet are in a square yard?
There are 9 square feet in 1 square yard. To convert square feet to square yards, divide by 9.
What is a waste factor and why is it important?
The waste factor accounts for cuts, seams, irregular edges, and mistakes. A typical waste factor is 5-10% to ensure you don't run short.
How many rolls of sod do I need for a 10×10 area?
A 10×10 area is 100 sq ft. With 10% waste (110 sq ft) and 2.5 sq ft rolls, you need 44 rolls.
How much sod do I need for 1 acre?
1 acre = 43,560 sq ft. At 2.5 sq ft per roll, you need about 17,424 rolls. A pallet covers 450 sq ft, so you'd need about 97 pallets.
How do I calculate sod for an irregular shape?
Divide the irregular shape into regular shapes (rectangles, triangles, etc.), calculate each area, and add them together. This calculator supports common shapes.
What is the best time of year to lay sod?
Late spring and early fall are ideal because temperatures are moderate and rainfall is more consistent. Avoid extreme heat or cold.
How do I prepare the soil for sod?
Remove existing grass and weeds, till the soil to a depth of 4-6 inches, level the ground, and add topsoil or compost if needed. The soil should be moist but not wet.
How long does it take for sod to root?
Sod typically roots within 10-14 days with proper watering. Keep the sod moist but not waterlogged during this period.
How do I water newly laid sod?
Water daily for the first 2 weeks, then every other day for the next 2 weeks. After that, water deeply 2-3 times per week. Early morning watering is best.
How much does sod cost?
Sod costs vary by region and type, but typically range from $0.30-$0.80 per square foot for the sod itself, plus installation costs.
Can I lay sod over existing grass?
No, existing grass must be removed before laying sod. The new sod needs direct contact with prepared soil to establish roots.
What is the difference between sod and seed?
Sod is mature grass that comes in rolls and is ready to install immediately. Seed is planted and takes 2-3 weeks to germinate and several months to establish.
How do I maintain new sod?
Wait until the sod is rooted (about 2 weeks) before mowing. Mow at a higher setting (3-4 inches) for the first few cuts. Fertilize after 4-6 weeks.
Can I walk on new sod?
Avoid walking on new sod for at least 2 weeks to allow the roots to establish. After that, you can walk on it but avoid heavy traffic.
