Grass seed calculator

Calculate how much grass seed you need for a new lawn or overseeding. Rates are extension-style ranges in lb per 1,000 sq ft, converted for your lawn size.

Enter area to see seed needed.

Rates are approximate ranges summarized from university extension guidance—not agronomic advice for your site. Adjust for germination %, seed quality, and local recommendations. St. Augustine is typically established with sod or plugs, not seed.
