Sod Calculator

This sod calculator helps you estimate how much sod you need to cover your lawn or yard. Whether you have a simple rectangular area, a circular lawn, or an L-shaped yard, this tool calculates the total square footage and converts it into the number of sod rolls and pallets required. A standard sod roll measures 2 feet by 5 feet, covering 10 square feet, while a full pallet typically covers about 450 square feet.

Best time to lay sod: The ideal time to install sod depends on the grass type. Cool-season grasses like Kentucky bluegrass and fescue are best laid in early fall or early spring when temperatures are mild. Warm-season grasses such as Bermuda, Zoysia, and St. Augustine should be installed in late spring or early summer when they are actively growing. Avoid laying sod during extreme heat or freezing conditions.

Soil preparation: Proper soil preparation is critical for sod success. Start by removing existing grass, weeds, and debris. Till the soil to a depth of 4 to 6 inches and amend with compost or topsoil if needed. Grade the area so it slopes away from buildings for drainage, and rake it smooth. The final soil level should be about 1 inch below adjacent sidewalks or driveways to account for the thickness of the sod.

Watering schedule: Newly laid sod needs heavy watering for the first two weeks. Water 2 to 3 times daily for the first week to keep the sod and soil beneath it consistently moist. During the second week, reduce to once daily. By the third and fourth weeks, transition to every other day, watering more deeply to encourage root growth. After about 4 weeks, the sod should be established and you can move to a normal watering schedule of 1 to 1.5 inches per week.

Rolls vs. pallets: For small areas or patching, buying individual sod rolls is practical. For larger projects, ordering by the pallet is more cost-effective and ensures uniform freshness. Most suppliers recommend installing sod within 24 hours of delivery. Always add 5 to 15 percent extra to your calculated area to account for trimming around curves, edges, and obstacles. The waste percentage you choose should reflect how complex your lawn shape is.
