How much material for a 75 ft privacy fence?

Data checked October 2026

Short answer

A 75 ft wood privacy fence 6 ft tall takes 181 pickets (164 plus 10% extra), 11 posts, 30 2×4 rails and 44 bags of 50-lb Fast-Setting concrete.

5.5-in pickets butted tight: 900 in ÷ 5.5 in = 163.6 → 164 pickets, 181 with 10% spare for splits and knots.
11 posts — 9 line posts plus 2 end posts (10 sections). With a 4-ft gate in the run it becomes 12 posts, 2 of them gate posts, and 181 pickets; bent into a U of 18.75, 37.5 and 18.75 ft it takes 12 posts.
Buy 10-ft posts: a 6-ft fence buries 36 in (a third of the post) on 4 in of gravel, so it needs 9' — 8-ft posts would leave only 24 in in the ground.
3 rails per section → 30 2×4×8 rails, plus 984 2-in and 90 3-in galvanized screws or nails.
Concrete: 44 × 50-lb Fast-Setting (4 per post, 0.52 yd³) — 2,200 lb to haul and about 44 gal of water.
Materials come to about $1,217 ($16.23/ft) at October 2026 prices, versus $1,125–$3,375 installed (Modernize, Aug 2026).
Built in cedar instead of pressure-treated pine, the same materials run about $1,521 ($304 more).
At 6-ft post spacing — stiffer in high-wind areas — the run takes 14 posts instead of 11.

End × 2	4×4 × 10 ft	10 × 40 in	4 bags

Each post goes 36 in into the ground on 4 in of gravel, so a 6-ft fence needs posts at least 9' long. Concrete stops 3 in below grade so soil or sod can cover it.

Concrete: 44 × 50-lb Fast-Setting

13.9 ft³ · 0.52 yd³

Counted hole by hole: 4 per line & end post. Dry-poured bags can't be split between holes, so each post rounds up.
Water: about 44 gal (1 gal poured over each 50-lb bag). Weight to haul: 2,200 lb.
Filling the hole to the top with no gravel or soil cap would take 5 bags per line post — that is why bag counts online disagree.
Wait 4 hours before hanging rails, panels or gates on the posts.
With 80-lb Concrete Mix instead: 33 bags, about $214 versus $351 — cheaper per yard, but it must be mixed first and cures for 24 hours.

Pickets: 181

Fence sections: 164
Gate leaves: 0
Spare (10%): 17
On center: 5.5 in

Boards butted edge to edge — 2.18 per foot, 18 per 8-ft section. Keep the bottoms 2 in off the ground so they don't wick up water.

These holes take more than 30 in of concrete. Quikrete says to dry-pour Fast-Setting in lifts: fill to 30 in or less, soak with water, then add the rest.

Before you dig

Call 811 (free) a few days ahead to have buried utilities marked. Confirm the property line and set posts a few inches inside it, and check permit, zoning and HOA height rules — front-yard limits are often lower than backyard ones. In cold climates, ask your building department for the local frost depth and enter it above — posts that stop short of it can heave.

How this was worked out

Posts: 75 ft ÷ 8 ft maximum spacing = 9.38, rounded up to 10 sections, spaced evenly at 7' 6". A straight run needs one more post than it has sections: 10 + 1 = 11. Every corner shares a post; every gate adds two.

Concrete per post: a 10-in hole has 78.5 sq in of area; minus the 3.5 × 3.5 in post leaves 66.3 sq in. Concrete fills 33 in (the 36-in embedment minus a 3-in soil cap): 66.3 × 33 ÷ 1,728 = 1.27 cu ft ÷ 0.375 cu ft per bag = 3.38 → 4 bags.

Prices used: 4×4×10 ft ground-contact PT posts $19.68; Pressure-treated pine dog-ear pickets, 5.5 in × 6 ft $2.28; 2×4×8 ft ground-contact PT rails $6.98 (estimate); Quikrete Fast-Setting Concrete Mix (No. 1004), 50 lb bags $7.97; All-purpose gravel, 0.5 cu ft bags $6.95.
