Grass Seed Calculator
Estimate grass seed in pounds for any lawn size.
For a new lawn, use 4–6 lb of grass seed per 1,000 ft². For overseeding, use 2–3 lb per 1,000 ft². To calculate the amount needed, multiply the application rate by the lawn area, then divide by 1,000. The appropriate rate depends on whether you are starting a new lawn or overseeding thin turf.

Sod guide
Sod is sold by the square foot, piece, or pallet, with one pallet typically covering 400–500 sq ft. Order 5–10% extra for cuts and waste. For successful sod installation, choose a species suited to your climate, prepare the soil thoroughly, lay the sod within 24 hours, and water it immediately.
