Sod Calculator
Find how much sod you need for a new lawn or a patch of bare ground. This free turf calculator measures natural-grass coverage in square feet, square yards and square meters, then converts it to rolls or pallets using your supplier's sizes.

How Much Sod Do I Need?
For a rectangular lawn, multiply length by width. Add separate patches and subtract paths, flower beds or other spaces inside those measurements. You need the area where grass will actually go, not your lot's total square footage.
Use circle mode for a round patch and enter its diameter. For a triangle, the height must meet the base at a right angle; a sloping edge is not the height. A lawn measured on a map can go straight into known-area mode. For an irregular boundary, the irregular landscape area guide explains how to divide it into measurable sections.
Net lawn area = sum of section areas − excluded area
Required coverage = net lawn area × (1 + extra allowance ÷ 100)
Whole units to buy = required coverage ÷ coverage per unit, rounded up
How much sod do I need for 200 square feet?
With no allowance, you need 200 ft² of coverage. If the selected roll covers 10 ft², that is 20 rolls. If it covers 7.5 ft², 200 ÷ 7.5 = 26.67, so buy 27 whole rolls, covering 202.5 ft². Those roll sizes are examples: enter the size your supplier actually sells.
Adding a chosen 5% allowance changes the requirement to 210 ft²: 21 of the 10 ft² rolls or 28 of the 7.5 ft² rolls. The calculator keeps the cut allowance separate from coverage left over because you bought whole units. Do not add the same allowance again to a supplier's already-adjusted quantity.
Sod Rolls, Pieces and Pallet Coverage
A sod pallet calculator needs the area on the pallet, not just the number of pallets or the grass name. Farms cut and package turf differently. A roll's coverage is its unrolled length × width; the diameter of the rolled-up bundle does not tell you the lawn area it covers.
| Coverage per pallet | Full pallets | Purchased coverage | Above the 1,050 ft² requirement |
|---|---|---|---|
| 400 ft² | 3 | 1,200 ft² | 150 ft² |
| 450 ft² | 3 | 1,350 ft² | 300 ft² |
| 500 ft² | 3 | 1,500 ft² | 450 ft² |
Whole-pallet rounding can leave substantially more sod than the cut allowance. Ask whether the farm sells individual rolls or split pallets. If so, select the roll or piece option for that quote; the tool does not assume that every supplier sells partial pallets.
For a St. Augustine sod calculation, use exactly the same lawn measurements and enter the listed St. Augustine product coverage. Grass variety does not change your yard's area, but the farm's package can change your order quantity.
When comparing prices, compare equal coverage: pallet price ÷ pallet area gives the price per square foot or square meter. The optional price field estimates the sod you will buy in the selected format. It is a material subtotal, not an installed lawn quote.
Sources & Methodology
Rectangle = length × width; circle = π × (diameter ÷ 2)²; triangle = base × perpendicular height ÷ 2. Areas are added before the exclusion and allowance are applied. The order is rounded up once to the chosen whole purchasing unit. 1 yd² = 9 ft² and 1 ft² = 0.09290304 m². No pallet size, waste percentage or product price is assumed.
