How much grass seed for 1,000 sq ft?
A new 1,000 square foot tall fescue lawn needs about 6 pounds of seed, at a typical rate of 6 lb per 1,000 sq ft: 1 bag of 7 lb. The usual range is 5–8 pounds; Kentucky bluegrass would need only about 2 pounds, and overseeding fescue about 4 pounds.
How to work it out
- 1,000 sq ft ÷ 1,000 × 6 lb = 6 lb
- 6 lb ÷ 7 lb per bag = 1 bag
A thousand square feet is the unit every seed label is written in, so this is the number to anchor on. Tall fescue is one of the most widely sold lawn seeds in the transition zone and much of the US, and its large seed means high pounds per area. The table below compares every grass at this size.

- 6 lb per 1,000 sq ft
- Straw to cover new seed (optional)
- 1–2 bales of weed-free straw (about 50–75 lb)
- Starter fertilizer
- 4 lb of a 24-25-4 starter (≈1 lb phosphate per 1,000 sq ft)
- Cool-season grasses usually establish best from late-summer / early-fall seeding, with spring as a second choice.
- No weed-and-feed or crabgrass preventer around seeding. Most of them stop grass seed from sprouting too. Rutgers and UNH Extension: use only a weed product whose label says it is safe for newly seeded lawns, and read it before you buy.
- Straw is optional: use weed-free straw (not hay), spread thin and even. It keeps the seed damp and stops it washing off slopes.
- More seed isn’t better — overcrowded seedlings compete and thin out. Good seed-to-soil contact and steady moisture matter more.

What to know about seeding 1,000 sq ft of tall fescue
Six pounds sits just under a common bag size: many tall fescue products come in 7 lb bags, so one bag covers a new 1,000 sq ft at this rate with about a pound to spare for thin spots. Check the label before you rely on it, because blends with a slice of bluegrass carry a lower rate and cheap blends with a lot of annual ryegrass or filler carry a higher one. Extension rates run from about 4–6 lb (Rutgers) to 6–8 lb (Penn State), so anywhere in that band is reasonable.
Seed quality changes the real amount. The pure live seed adjustment means a bag at 90% purity and 85% germination needs nearly 8 lb to put the same live seed on 1,000 sq ft as 6 lb of pure live seed. Enter the two label numbers in More options and the calculator does the division; a cheap bag can end up costing more per live seed.
The common mistake at this size is treating a patch as a lawn. If you are fixing bare spots in an existing yard, measure only the bare areas (a few 5 × 10 ft patches may total 150 sq ft, about a pound of seed), and overseed the thin grass around them at the lower rate. Seeding the whole 1,000 sq ft at the new-lawn rate wastes seed and crowds the seedlings.
On bare soil, one or two bales of weed-free straw and about 4 lb of a 24-25-4 starter fertilizer finish the job. Timing matters as much as quantity: tall fescue is a cool-season grass that establishes best from late-summer to early-fall seeding.

Frequently asked questions
How much tall fescue seed to overseed 1,000 sq ft?
About 4 pounds, at 4 lb per 1,000 sq ft: roughly two-thirds of the new-lawn rate, because the existing grass already fills much of the ground.
How much Kentucky bluegrass seed for 1,000 sq ft?
About 2 pounds for a new lawn, at 2 lb per 1,000 sq ft. Bluegrass seed is far smaller than fescue, so the same area takes far fewer pounds.
My fescue bag says 8 lb per 1,000 sq ft. How much for 1,000 sq ft?
8 pounds: use the bag rate. That is 2 bags of 7 lb, so buy the next size up or a second small bag.
How much tall fescue for 1,000 sq ft if the label says 90% purity and 85% germination?
About 7.84 pounds of that seed (7.84 lb per 1,000 sq ft): the 6 lb pure live seed rate divided by 0.90 × 0.85. One 7 lb bag no longer covers it: that is 2 bags of 7 lb.
