100 ft

5% covers pickets split by a screw or culled for warp and knots. It is added once, to the pickets — the posts, rails and concrete are counted from the fence itself.

Assumptions

Every one of these is editable. Change one and the answer changes with it.

Assumption Value Confidence
Widest post spacing, woodPosts of a wood fence no more than 8 ft apart, center to center: the spacing Inch Calculator and Omni both work at, and the length of the 2×4 rail that spans a bay. ≈ in Trade convention

Gap under the picketsPickets stop about 2 in above the ground so they do not wick water; Freedom's vinyl kit sets its panels about 2 in up, and 2 in is the most ISPSC 305.2.1 allows over grass or gravel. ≈ in Trade convention

What a fence costs in materials

At the reference prices on the page, a 6 foot wood privacy fence round three sides of a back yard — 50, 100 and 50 feet — comes to $3,039.58 in materials, about $15 a foot. Every price is a box beside the row it prices: type your lumber yard's and the total follows. Labor, permits and hauling the dirt away are not on the list.

RowBoughtAtComes to
4×4 posts28 × 10 ft$1.69 a foot$473.20
1×6 pickets461 × 6 ft$0.38 a foot$1,051.08
2×4 rails81 × 8 ft$0.60 a foot$388.80

Gravel16 × 50 lb$5.48$87.68

Where the money goes

The pickets are a third of it, and the concrete a quarter. Fast-setting mix is sold for setting posts — pour it dry, add water, and it sets in 20 to 40 minutes — but ordinary concrete mix in 80 pound bags does the same job for less: 59 bags at $5.68 instead of 94 at $7.98, and the fence comes to $2,624.58. Choose Concrete mix under Assumptions to see it. Cedar pickets run about twice the price of pressure-treated pine; type the price of the ones you are buying.

Lumber is priced by the foot because a yard prices a 10 foot post more than an 8: the list multiplies each board by its length, so a 6×6 gate post or a longer picket is priced right without a box for every length.

What is not counted

Post caps start unticked; at $7.98 each they would add $223.44. Stain, a post-hole auger rental, and the delivery are not on the list. The reference prices are listings read in October 2026, and they are a starting point, not a quote. We are not connected with any maker, store or supplier named here.
