How it works
The calculator multiplies the length by the width to get the area of the lawn, adds any extra area you enter, and adds a percentage for waste, since sod has to be cut to fit edges and curves. Then it divides by the area of each piece and rounds up, because you can only buy whole pieces. If you enter a price per square foot or meter, it also estimates the cost of everything you buy.
The formulas
Area = length × width + extra area
Pieces = area × (1 + waste) ÷ area of each piece, rounded up
Worked example
A lawn of 40 × 25 ft, with 5% extra, using pieces of 10 sq ft (2 × 5 ft rolls) at 0.35 per sq ft.
- Area: 40 × 25 = 1,000 sq ft.
- With waste: 1,000 × 1.05 = 1,050 sq ft.
- Pieces: 1,050 ÷ 10 = 105 pieces, covering 1,050 sq ft.
- Cost: 1,050 × 0.35 = 367.50.
Frequently asked questions
How much sod do I need for my lawn?
Measure the length and width of the lawn to get the area, add 5% to 10% for cuts and waste, and divide by the area of each piece of sod. A 40 × 25 ft lawn is 1,000 sq ft, so you would need about 105 pieces of sod that are 10 sq ft each.
What size does sod come in?
It varies by supplier and region. Common sizes are rolls of 2 × 5 ft (10 sq ft), smaller squares or slabs, and big rolls sold by the pallet. Ask your supplier for the exact area of each piece and enter it in the calculator.
How do I measure a lawn that is not a rectangle?
Split it into rectangles and add their areas. Measure the main rectangle with the length and width boxes, and add the others in the extra area box. For a circle, use πr². The 5% to 10% extra covers the cuts along curves and edges.
How soon should I lay the sod?
Sod is a living product, so lay it as soon as possible after it arrives, ideally the same day, and water it well. Plan the delivery for when your soil is ready, and ask your supplier for advice for your grass type and season.
