A fence estimate is three counts that hang off the total length: posts (by spacing), rails (by sections and runs), and pickets or panels (by length and gap). Add post-hole concrete, gates, and hardware and you have the full bill. This guide walks the whole line, from corner posts to cost.
Measure the total run of the fence in feet, following each straight segment around the property and adding them. Sketch the layout and mark every corner, end, and gate — these need posts regardless of spacing and often heavier posts, so the count is not just length ÷ spacing.
Line posts repeat along each run at the chosen spacing; divide run length by spacing and add one for the closing post. Then add corner, end, and gate posts on top. Spacing is usually 6 to 8 feet — closer for tall privacy fences or windy sites, since panels catch wind like a sail.
Rails (also called stringers) run horizontally between posts. Count the sections (gaps between posts) and multiply by rails per section: 2 rails for short or picket fences, 3 for tall or privacy fences to keep boards from warping. Rail stock is usually 8-ft lengths spanning post to post.
For board fences, the picket count depends on picket width and the gap between them. Add the picket width and the gap to get the spacing each picket consumes, then divide the fence length by it. For panel fences (vinyl, pre-built wood), the count is simply sections — one panel per section.
Posts: 16 line + ~2 corners + 2 gate = ~20. Rails: 15 sections × 3 = 45. Pickets: 1,440 ÷ 6 = 240. Plus concrete for 20 holes and one gate kit — that's the full material list before waste.
Each post is set in concrete for stability. Hole depth is about ⅓ the above-ground post height (deeper in frost regions, below the frost line), and diameter about 3× the post width. A typical 4×4 post in a 10-in hole takes one to two 50–60 lb bags of concrete; multiply by the post count.
Gates are estimated separately: each needs heavier gate posts, a gate frame or kit, hinges, a latch, and often a drop rod or cane bolt for double gates. Standard fasteners (screws or nails), post caps, and any stain or sealant round out the order. Don't forget to subtract gate openings from the picket run.

| Chain-link | $8–$20 / linear ft |
| Vinyl panel | $20–$40 / linear ft |
| Concrete per post | 1–2 bags |
| Install labor | $10–$30 / linear ft |
