How Much Grass Seed for 500 Square Feet?

4lbs of tall fescue

for a new lawn — see the table for other grasses and overseeding

Grass type	New lawn	Overseeding
Tall fescue	4 lb	2 lb
Sun & shade mix	3 lb	1.5 lb
Perennial ryegrass	4.5 lb	2.3 lb
Kentucky bluegrass	1.5 lb	0.8 lb
Bermuda	0.8 lb	0.4 lb
Zoysia	1 lb	0.5 lb

Seeding rates vary a lot by species — dense-seeded tall fescue needs about 8 lb per 1,000 sq ft for a new lawn, while Kentucky bluegrass needs only 3 lb, and Bermuda 1–2 lb. Overseeding an existing lawn takes about half the new-lawn rate.

More seed is not better: overseeded stands compete with themselves and thin out. Match the bag's stated rate when it differs from these typical values.
