How to estimate a fence project
Measure every straight section of fence and include returns, corners, and gate openings in the run. Property boundaries should be confirmed before measurements become an order.
Post count comes from the distance between supports. Pickets are based on their visible width plus the gap, while rails depend on the fence height and panel construction. Gates need their own framing and hardware.
Wood, vinyl, composite, and chain link behave differently in both price and installation. Use this result to compare directions, then verify local height limits, soil conditions, and the supplier's component sizes.
Formulas used
Picket count
length × 12 ÷ (picket_width + gap)Converts the run to inches and divides by the repeating picket pattern.
Concrete allowance
posts × bags_per_postUses a planning bag count; hole depth and diameter determine the actual pour.
Frequently asked questions
What to know before you order.
Does the fence estimate include a gate?
No. Add gate leaves, reinforced posts, hinges, latches, and framing separately.
How far apart should fence posts be?
Eight feet is common for many residential wood fences, but the panel system, wind exposure, soil, and local practice can change that spacing.
How much concrete goes around each post?
The amount depends on hole diameter, depth, post size, and soil. Treat the bag count as a planning range and confirm it with the installation method.
