How Much Grass Seed Do I Need?
Grass seed is measured in pounds per 1,000 square feet. Measure the lawn area, pick the seeding rate for your grass type, then multiply. A new lawn uses the full rate; overseeding an existing lawn uses about half.
- New lawn: use the full seeding rate for your grass type
- Overseeding: use about half the new-lawn rate
- Formula: Seed (lbs) = (Area in sq ft / 1,000) x rate
- Waste: add 5% for clean rectangles, 10% for slopes and patchy spots
For odd shapes, break the yard into rectangles, measure each one, and add the results before you order. Round up to the next full bag.
Key Takeaways
- Seed is measured in lbs per 1,000 sq ft
- New lawn uses full rate, overseeding uses half
- Seed = (area / 1,000) x rate
Seeding Rates by Grass Type
Every grass has its own seeding rate. Fescues need the most seed per square foot, while Bermuda, Zoysia, and Centipede need far less because the seed is tiny and the plants spread on their own.
- Tall Fescue: 8 lbs per 1,000 sq ft (new lawn)
- Perennial Ryegrass: 8 lbs per 1,000 sq ft
- Fine Fescue: 5 lbs per 1,000 sq ft
- Kentucky Bluegrass: 3 lbs per 1,000 sq ft
- Bermuda (seeded): 2 lbs per 1,000 sq ft
- Zoysia (seeded): 2 lbs per 1,000 sq ft
- Centipede: 0.5 lb per 1,000 sq ft
These are starting points. Always check the bag, because coated and blended seed can change the rate.
Key Takeaways
- Fescues and rye need 5-8 lbs per 1,000 sq ft
- Bluegrass needs about 3 lbs per 1,000 sq ft
- Bermuda, Zoysia, Centipede need 0.5-2 lbs
Grass Seed Cost in 2026
Grass seed runs $3-$40 per pound depending on the type. The high seeding rate on fescue is offset by a low price per pound, while a tiny amount of Centipede or Zoysia seed costs a lot more per pound.
- Tall Fescue / Perennial Rye: $3-$6 per lb
- Kentucky Bluegrass / Fine Fescue: $4-$8 per lb
- Bermuda (seeded): $6-$12 per lb
- Zoysia (seeded): $12-$18 per lb
- Centipede: $20-$40 per lb
- Starter fertilizer: $25-$45 per bag (covers ~5,000 sq ft)
- Professional seeding labor: $0.05-$0.15 per sq ft on top of materials
Seed is cheap compared to sod, but the prep and the watering schedule are where the real work hides. Price the grading as its own line on the bid.
Key Takeaways
- Seed: $3-$40 per lb by grass type
- Starter fertilizer: $25-$45 per bag
- Pro labor adds $0.05-$0.15 per sq ft

Quick Answer: How Much Grass Seed Do I Need?
Multiply your lawn area in thousands of square feet by the seeding rate for your grass type. Tall Fescue needs 8 lbs per 1,000 sq ft for a new lawn, so a 2,000 sq ft yard takes about 16 lbs. Kentucky Bluegrass needs only 3 lbs, and tiny-seeded Bermuda or Zoysia need 1-2 lbs. Overseeding an existing lawn uses about half the rate. Seed runs $3-$40 per pound depending on the type. Use the calculator above to get exact pounds, bags, and cost. Try EstimationPro free to turn that takeoff into a full client estimate.
Seeding Rate and Cost by Grass Type
| Grass Type | New-Lawn Rate (lb/1,000 sq ft) | Seed Cost (per lb) | Season |
|---|---|---|---|
| Tall Fescue | 8 | $3-$6 | Cool |
| Perennial Ryegrass | 8 | $3-$5 | Cool |
| Fine Fescue | 5 | $4-$7 | Cool |
| Kentucky Bluegrass | 3 | $4-$8 | Cool |
| Bermuda (seeded) | 2 | $6-$12 | Warm |
| Zoysia (seeded) | 2 | $12-$18 | Warm |
| Centipede | 0.5 | $20-$40 | Warm |
Overseeding an existing lawn uses about half the new-lawn rate. Starter fertilizer adds $25-$45 per 5,000 sq ft bag, and professional spreading labor runs $0.05-$0.15 per sq ft.

Worked Example: Seeding a New Front Yard
Say you are seeding a 60 ft by 40 ft front yard with Tall Fescue. That is 2,400 sq ft. Add 5% waste for the curved walkway and you are at 2,520 sq ft. At 8 lbs per 1,000 sq ft, you need about 20 lbs of seed, which is one 25 lb bag with a little left over for touch-ups. At $3-$6 per lb the seed runs $60-$120, plus one bag of starter fertilizer at $25-$45. If the client wants you to grade and spread it, add $0.05-$0.15 per sq ft for labor, which is another $120-$360. The full installed range lands around $205-$525.
Worked Example: Overseeding a Thin Backyard
Now take a tired 30 ft by 30 ft backyard, 900 sq ft, that just needs a fall overseed with Kentucky Bluegrass. Bluegrass is 3 lbs per 1,000 sq ft for a new lawn, but overseeding uses half that, so call it 1.5 lbs per 1,000. That is about 1.4 lbs of seed, well under a single 3 lb bag. At $4-$8 per lb that is roughly $6-$11 in seed. Add a bag of starter fertilizer and you are still under $50 in materials. This is the kind of small job where the drive time and the cleanup cost more than the seed, so I price a minimum charge and move on.
Where Grass Seed Jobs Go Wrong
- Using the overseed rate on bare dirt. A new lawn needs the full rate. Spread it like an overseed job and you get thin, weedy turf that the client will blame on you. Match the rate to the job.
- Seeding into a hard, crusted surface. Seed needs soil contact to germinate. Scratch the top inch, lay 2-4 inches of good topsoil on bare areas, and rake it smooth before you spread. The prep matters as much as the seed.
- Skipping the starter fertilizer. New seed roots faster with phosphorus. One $25-$45 bag covers 5,000 sq ft and is cheap insurance against a patchy stand.
- Walking away after spreading. New seed dies if it dries out. Keep the top inch damp with light daily watering for the first two to three weeks. If you are the contractor, put the watering schedule in writing or you will get the callback when it does not come up.
- Seeding at the wrong time. Cool-season grasses go down in early fall or spring. Warm-season grasses go down in late spring once the soil warms. Seed at the wrong time and germination drops no matter how much you spread.

How to Use This Calculator
Pick your grass type
Choose Tall Fescue, Kentucky Bluegrass, Perennial Ryegrass, Fine Fescue, Bermuda, Zoysia, or Centipede. Each one has a different seeding rate and a different best climate, so match it to your region and sun exposure first.
Enter the lawn dimensions
Add the length and width of the area in feet. For odd shapes, break the yard into rectangles, measure each one, and add the results together before you order.
Set new lawn or overseeding
A bare new lawn uses the full seeding rate. Overseeding a thin existing lawn uses about half. Flip the overseed toggle so the pound count matches the job, and add 5-10% waste for slopes and edges.
Review pounds, bags, and cost
See total pounds of seed, bag count, and estimated cost with optional starter fertilizer and installation labor. Always round up to the next full bag so you do not run short halfway across the yard.

Frequently Asked Questions
How much grass seed do I need?
Measure the lawn area in square feet, then multiply by the seeding rate for your grass type. Use the formula: Seed (lbs) = (Area / 1,000) x rate. For a 2,000 sq ft Tall Fescue lawn at 8 lbs per 1,000 sq ft: (2,000 / 1,000) x 8 = 16 lbs of seed. Add 5-10% for waste on slopes and edges.
How much grass seed per 1,000 square feet?
It depends on the grass. Tall Fescue and Perennial Ryegrass need 8 lbs per 1,000 sq ft for a new lawn, Kentucky Bluegrass needs about 3 lbs, and tiny-seeded grasses like Bermuda and Zoysia need just 1-2 lbs. Centipede needs as little as 0.5 lb. Overseeding an existing lawn uses about half these rates.
How much does grass seed cost?
Grass seed runs $3-$40 per pound in 2026. Fescue and ryegrass sit at $3-$6 per lb, Kentucky Bluegrass and fine fescue run $4-$8, Bermuda is $6-$12, and Zoysia or Centipede climb to $12-$40 per lb. A 2,000 sq ft fescue lawn needs about 16 lbs, so the seed alone runs $48-$96 plus starter fertilizer.
Is it cheaper to seed or sod a lawn?
Seeding is far cheaper up front, usually $0.05-$0.20 per sq ft installed versus $0.90-$2.00 for sod. Seed takes weeks to fill in and needs daily watering, while sod is an instant lawn. I tell clients the same thing every time: seed if you have patience and a watering plan, sod if you need it green now. Compare the two with the sod calculator before you decide.
How do contractors price a grass seeding job for a client?
Most contractors price seeding three ways: seed and fertilizer by the bag, prep and grading by the hour, and spreading labor at $0.05-$0.15 per sq ft. I always quote the grading separately because that is where the real labor hides, and I add a line for the first round of watering or a warranty on germination. Bundle the dirt prep and seeding into one clean bid with the landscaping cost calculator.
How long does it take to estimate a seeding job?
A simple rectangular lawn takes about 10 minutes to measure and price. An odd-shaped yard with beds, slopes, and bare patches takes 20-30 minutes once you account for the prep. Need topsoil under the seed too? Run that volume through the topsoil calculator so you order both in one trip.
Should I put down starter fertilizer with grass seed?
Yes. A starter fertilizer high in phosphorus helps new seed root, and one bag covers about 5,000 sq ft for $25-$45. Skip it and you get thin, slow germination. Spread it the same day you seed, water it in, and keep the top inch of soil damp until the grass is up.
