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.

Frequently asked

How many pallets of sod for my yard?+
One pallet covers about 450 sq ft. For a 4,500 sq ft lawn you need 10 pallets. Add one extra pallet for irregular shapes and trimming.
How much seed do I need?+
For new lawns, plan on 1 lb per 250 sq ft. For overseeding existing lawns, 1 lb per 500 sq ft is usually enough.
Should I include the area under my deck?+
No — anywhere grass can't grow (shade, hardscape, mulch beds) should be subtracted from your lawn area.
