HOW IT WORKS

Formula and assumptions

Divide the fence run by post and panel spacing, add the terminal post, then estimate rails and pickets by section.

The run is measured along the fence line.
Straight-run quantities exclude special gate and corner assemblies.

FIELD CHECK

Before you order

Wind exposure, height, post depth, gate width, board overlap, top profile, and local restrictions can change both framing and quantity.

Worked example

Example: with fence run 160 ft, maximum post spacing 8 ft, panel / section width 8 ft, rails per section 3, the privacy fence calculator returns 160 lin ft for fence length. The supporting check is posts: 21 posts. Replace the prefilled measurements and supplier assumptions with the project values before ordering.

Planning limitation

Verify property lines, easements, permits, wind design, utility locations, pool barriers, and local fence rules.

WHEN TO USE IT

Best use of this calculator

Use the result as a planning estimate, then verify field measurements and product-specific data before ordering or building.

INPUTS EXPLAINED

What each input means

Fence run: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Maximum post spacing: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Panel / section width: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Rails per section: Enter the project value used by the calculation.
Picket width: Enter the measured value and choose the matching unit (in, ft, cm, mm).
Gap between pickets: Enter the measured value and choose the matching unit (in, ft, cm, mm).
Picket waste: Enter the project value in %.
Price per panel / section: Enter the project value in $.

COMMON MISTAKES

Checks that prevent bad estimates

Mixing units or entering a measurement in a different unit than the selected field unit.
Using a planning default when the exact manufacturer or supplier specification is available.
Rounding intermediate measurements too early instead of rounding the final purchase quantity.
Ignoring waste, compaction, cuts, laps, settlement, or full-package rounding where the project requires them.

SOURCES & REVIEW

How this estimate is supported

The implemented formula, assumptions, and worked example on this page are the calculator-specific reference. BuildYard's broader rules are documented in the Calculation Methodology and Sources & References.

For material density, coverage, yield, dimensions, package quantity, price, and other product-specific values, the current manufacturer or supplier specification should override a planning default.

COMMON QUESTIONS

Privacy Fence Calculator FAQ

What does the Privacy Fence Calculator calculate?

It converts the measurements for six-foot wood, composite, or panel privacy fences into the buying units normally used for closely spaced privacy-fence components, with the relevant waste, package, weight, or cost outputs shown on the result card.

How accurate is this privacy fence calculator?

The geometry is calculated from the values you enter. Final ordering accuracy still depends on field measurements, supplier density or coverage, product dimensions, compaction, cuts, and the selected allowance.

What should I verify for six-foot wood, composite, or panel privacy fences?

Wind exposure, height, post depth, gate width, board overlap, top profile, and local restrictions can change both framing and quantity. Confirm the selected product, field conditions, and purchasing increments before placing the order.

Should I round the result up?

Yes for indivisible buying units such as bags, sheets, bundles, pallets, boxes, bars, and truck loads. The calculator rounds those purchase quantities up automatically.
