How Much Grass Seed for 1/4 Acre? (2026 Guide)
How much grass seed for 1/4 acre? A quarter acre is 10,890 sq ft: a new lawn at 6 lb per 1,000 sq ft needs about 65 lb of seed — 13 five-pound bags.
What 1/4 acre means in square feet
Seed rates are quoted per 1,000 sq ft, so start by converting the lot. One acre is 43,560 sq ft, and a quarter of that is 10,890 sq ft — think of a rectangle about 80 ft wide and 136 ft deep. Measure the actual turf you plan to seed and skip driveways, beds and the house footprint. For an irregular shape, split it into rectangles and triangles, add the pieces, then feed the total into the grass seed calculator.
The quick math: seed rate × area
Most turf mixes call for 5–7 lb per 1,000 sq ft when starting from bare soil. We'll use 6 lb per 1,000 sq ft, the middle of the range most bag labels list. Divide the lawn by 1,000 and multiply by the rate:
10,890 ÷ 1,000 = 10.89, then 10.89 × 6 ≈ 65 lb.
In bags, that's 65 ÷ 5 = 13 five-pound bags. If you buy big sacks instead, 65 lb is one 50-lb bag plus 15 lb sold loose — handy when a feed store sells by the pound. Rounding up a little is smart: 14 bags (70 lb) leaves a small buffer for reseeding thin patches and edges.
Grass seed needed for common lawn sizes
New-lawn amounts use 6 lb per 1,000 sq ft; overseeding amounts use 3 lb per 1,000 sq ft (about half, for the reasons below). Bag counts are whole 5-lb bags, rounded up:
| Lawn size | Area (sq ft) | New lawn @ 6 lb/1,000 | 5-lb bags (new lawn) | Overseeding @ 3 lb/1,000 |
|---|---|---|---|---|
| 1/8 acre | 5,445 | 33 lb | 7 | 16 lb |
| 1/4 acre | 10,890 | 65 lb | 13 | 33 lb |
| 1/2 acre | 21,780 | 131 lb | 27 | 65 lb |
| 1 acre | 43,560 | 261 lb | 53 | 131 lb |
Read across the second row: the 1/4-acre lawn needs 65 lb at the new-lawn rate. Notice the pattern — overseeding a lawn takes about the same weight as seeding a lawn half its size from scratch.
New lawn vs. overseeding: why the rate halves
A new lawn starts bare, so every seed has to germinate and fill the soil on its own — that's why the rate is higher. An established lawn already has grass; overseeding only thickens thin spots and fills bare patches, so the seed doesn't have to work as hard. At 3 lb per 1,000 sq ft, the 1/4-acre overseed comes to 10.89 × 3 ≈ 33 lb. Still not sure which situation you're in? The grass seed calculator covers both modes.
Buying and seeding tips for a 1/4-acre lawn
- Buy in bulk for a lawn this size — a dozen retail 5-lb bags work fine, but landscape suppliers and co-ops sell loose seed by the pound and 50-lb sacks at a lower per-pound price; you need about 65 lb plus a small buffer.
- Test the soil before you spend on seed — a low-cost pH and nutrient test tells you whether lime or starter fertilizer is needed first; seed thrown on poor soil wastes both money and a season.
- Calibrate your spreader — set the opening to the rate printed on the bag and do a test pass over a tarp; overlapping passes at a wide setting can lay down nearly twice the seed you planned for.

FAQ
How much grass seed do I need for a 1/4-acre lawn?
About 65 lb for a new lawn. A 1/4 acre is 10,890 sq ft, and at the standard rate of 6 lb per 1,000 sq ft: 10,890 ÷ 1,000 = 10.89, so 10.89 × 6 ≈ 65 lb of grass seed.
How many 5-lb bags of grass seed cover a 1/4 acre?
Thirteen. A new lawn on a 1/4 acre needs about 65 lb of seed at 6 lb per 1,000 sq ft, and 65 ÷ 5 = 13 five-pound bags. Buying 50-lb sacks instead, grab one 50-lb bag plus about 15 lb sold loose.
How much grass seed do I need to overseed a 1/4-acre lawn?
About 33 lb. Overseeding an established lawn runs at about 3 lb per 1,000 sq ft, and 10.89 × 3 ≈ 33 lb — roughly half the new-lawn amount, or about seven five-pound bags.
