Sod Calculator
Calculate the total square feet, square yards, and number of sod rolls required to plant a new lawn.
Calculation Results
The total required lawn area to cover, including waste.
The total required lawn area in square yards (standard industry unit).
Total number of standard rolls of sod needed (assumes standard roll covers 9 square feet).
How This Calculator Works
To use the Sod Calculator:
- Enter the length and width of the lawn area you want to plant. If the yard has an irregular shape, split it into smaller rectangles and sum the dimensions.
- Specify a waste allowance (10% is standard for square lawns; increase to 15% for lawns with curved landscape borders, flower beds, or walkways).
- The calculator immediately outputs the total square footage, square yardage, and the exact count of standard sod rolls to purchase.
Formula & Calculations
Lawn area is calculated by multiplying length by width and adding a waste factor (typically 10% to account for cutting and shaping along curved edges):
Lawn Area (Square Feet) = Length × Width × (1 + Waste / 100)
To convert this square footage to square yards (how sod farms usually price and sell large orders), we divide by 9 (since 1 square yard = 9 square feet):
Lawn Area (Square Yards) = Lawn Area (Square Feet) / 9
Standard retail rolls of sod measure 1.5 feet wide by 6 feet long, covering exactly 9 square feet. The count of individual sod rolls required is calculated as:
Sod Rolls = ceil(Lawn Area (Square Feet) / 9)
Step-by-Step Calculation Examples

- width: 30
- waste: 10
- area_sq_ft: 1,650.0 sq ft
- area_sq_yd: 183.3 sq yd
- sod_rolls: 184
Frequently Asked Questions
What size is a standard roll of sod?
The standard roll of sod measures 1.5 feet (18 inches) wide by 6 feet long, covering exactly 9 square feet (1 square yard). Sod farms also sell larger rolls (e.g. 30" wide by 50' or 100' long) for commercial tractor installations.
What is the standard waste factor for installing sod?
A waste factor of 5% to 10% is standard. For straight rectangular lawns, 5% is sufficient. If you have curves, garden islands, pathways, or flower beds, use 10% to 15% to cover the pieces cut off at angles.
How much does sod cost on average?
Sectional sod rolls typically cost between $0.35 and $0.85 per square foot (approx. $3.15 to $7.65 per standard roll) depending on grass type (e.g. Bermuda, Fescue, Bluegrass) and delivery distance.
How long can sod rolls stay on a pallet before laying?
Sod is a living plant and should be installed within 24 to 36 hours of harvesting in cool weather, and within 12 to 24 hours in hot summer weather. Left on the pallet too long, the grass will decay and die.
How much soil prep is needed before laying sod?
You should rototill the top 4 to 6 inches of soil, clear away any weeds, rocks, or debris, add compost soil amendments, rake it flat, and apply a starter fertilizer before laying the turf.
