Enter your fence length and picket size — get pickets, posts, rails, and concrete, with the math shown. Free, no signup, works for privacy and spaced-picket layouts.
This counts a straight run with posts 8′ on center. Real yards have corners, gates, slopes, and that one stretch where the neighbor's shed is in the way — that's what the full satellite estimator handles, down to every bracket and bag of concrete.
Pickets = fence length in inches ÷ (picket width + gap), rounded up, plus waste. A 100′ privacy fence with 5½″ pickets: 1,200″ ÷ 5.5″ = 219 pickets, +5% waste ≈ 230 pickets.
Posts = length ÷ 8′ spacing, rounded up, +1 to close the run. 100′ ÷ 8 = 13 sections → 14 posts.
Rails = sections × rails per section. 13 sections × 3 rails = 39 rails for a 6′ fence.
Concrete = posts × 2 bags of 50 lb fast-setting mix (10″ hole, 24″ deep).
| Fence length | Privacy (no gap) | Spaced (2½″ gap) | Posts | Rails (3/section) |
|---|---|---|---|---|
| 50 ft | 115 pickets | 79 pickets | 8 | 21 |
| 100 ft | 230 pickets | 158 pickets | 14 | 39 |
| 150 ft | 344 pickets | 237 pickets | 20 | 57 |
| 200 ft | 459 pickets | 315 pickets | 26 | 75 |
| 300 ft | 688 pickets | 473 pickets | 39 | 114 |
| Picket type (6′ dog-ear) | Typical each |
|---|---|
| Pressure-treated pine | $2.50 – $4.50 |
| Western red cedar | $4.00 – $8.00 |
| Vinyl (per equivalent panel width) | $6.00 – $12.00 |
| Composite | $9.00 – $18.00 |
Prices vary meaningfully by region and by week — lumber is a commodity. A 230-picket fence swings by hundreds of dollars depending on when and where you buy, which is why a materials list beats a guess.
96″ ÷ 5.5″ ≈ 18 pickets butted tight; about 12 with a 2½″ gap.
Privacy fences butt pickets tight (they'll shrink and open ~¼″ gaps as the wood dries — that's normal). Spaced-picket looks use 1¾″–2½″ gaps and cut your picket count by roughly a third.
5% on a straight run; 10% with corners, slopes, or gates. Matching a lumber batch three weeks later is harder than storing ten extra boards.
8′ on center, max. Go 6′ in high-wind areas. Never stretch spacing to save posts — that's how fences end up in the neighbor's yard by February.
