Sod Calculator
Estimate sod square footage, rolls, and pallets for lawns.
This sod calculator estimates the square footage of sod needed for a lawn, and converts that into the number of rolls or pallets to order, including a waste allowance for irregular lawn shapes.
Enter your lawn dimensions, and the calculator returns the sod area needed along with rolls or pallets required.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 40 ft × 30 ft lawn, 10% waste, 9 sq ft/roll | 147 rolls | Area = 40 × 30 = 1,200 sq ft. With waste: 1,200 × 1.10 = 1,320 sq ft. Rolls = 1,320 ÷ 9 ≈ 146.7, rounded up to 147. |
| 20 ft × 20 ft lawn, 5% waste, 9 sq ft/roll | 47 rolls | Area = 20 × 20 = 400 sq ft. With waste: 400 × 1.05 = 420 sq ft. Rolls = 420 ÷ 9 ≈ 46.7, rounded up to 47. |
From Square Footage to Rolls and Pallets
Once total square footage is calculated (length x width x (1 + waste)), that figure is divided by the coverage of one sod roll (commonly around 9-10 sq ft per roll) to find the number of rolls needed, and rolls are further grouped into pallets (commonly 450-500 sq ft per pallet) for larger orders.
Why Irregular Lawns Need Extra Sod
Curved beds, tree islands, and other irregular lawn features create more cutting and waste than a simple rectangular lawn, so a higher waste allowance (sometimes 10% or more) is often recommended for lawns with complex shapes compared to a straightforward rectangular yard.

Frequently Asked Questions
How much sod do I need for my lawn?
Multiply your lawn's length by width to get total square footage, then add a waste allowance (commonly 5-10%, more for irregular shapes) before converting to rolls or pallets.
How much area does one roll of sod cover?
It varies by supplier, but standard sod rolls commonly cover around 9-10 square feet each.
How much sod is in a pallet?
Pallet coverage varies by supplier, but commonly covers around 450-500 square feet, which is useful for estimating total pallets needed for larger lawn areas.

What does the Sod Calculator calculate?
Estimate sod square footage, rolls, and pallets for lawns. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this sod use?
The formula is: sod area = length * width * (1 + waste). Commercial sod farming - growing turfgrass specifically to be harvested and transplanted as an instant lawn - developed as an industry in the US in the mid-20th century alongside post-war suburban housing expansion, when new homeowners wanted an immediate, established lawn rather than waiting months for grass seed to fill in.
