Grass Seed Calculator — Pounds Needed for a Lawn

How the grass seed calculator works

Seed by rate: new lawns 4–6 lb per 1,000 ft², overseeding 2–3 lb per 1,000 ft². Multiply your rate by area / 1,000.

4–6 lbs for a new Kentucky bluegrass or fescue lawn; 2–3 lbs to overseed thin turf.

Cool-season grasses: early fall. Warm-season grasses: late spring after soil hits 65°F.

Estimate gravel by area and depth in tons or cubic yards.

Mulch

Estimate mulch in bags and cubic yards for any bed size.

Topsoil
