Lawn Square Footage Calculator
Measure your lawn area for sod installation, grass seed coverage, fertilizer application, or any lawn care project.
Lawn Area Calculator
Sod, seed, or hydroseed?
Sod gives instant lawn at the highest cost per square foot. A standard pallet covers 450 sq ft (or 50 sq yd) and arrives ready to install.
Seed is far cheaper per square foot but requires 2–4 weeks to germinate and 2–3 months to establish. One pound of seed typically covers 250 sq ft for new lawns or 500 sq ft for overseeding.
Measuring an irregular yard
Most yards aren't simple rectangles. Use Google Maps or your phone's measure tool to get a baseline. For accuracy, break the yard into rectangles and triangles, measure each, and sum the areas.
Subtract obvious non-grass areas: driveways, patios, garden beds, decks, sheds. Don't worry about removing every tree well — small subtractions average out.
Pro tips
Order by the pallet
Sod is sold by the pallet (450 sq ft typical). Don't round up too aggressively — sod has a 24–48 hour install window before it dies.
Time your seeding
Cool-season grasses go down in early fall or spring. Warm-season grasses prefer late spring through early summer.
Use a fertilizer app rate
Fertilizer bags rate coverage by sq ft. A 10,000 sq ft bag of starter fertilizer covers most quarter-acre lawns once.
Subtract hardscape
Patios, driveways, walkways, and beds shouldn't be in your sod calculation.
