A privacy fence lives or dies on two things most homeowners overlook until it is too late: the gap between boards and the wood species. Well-built wood privacy fence panels block sightlines completely, survive twenty years of weather, and raise your property’s curb appeal, while a cheap panel of green pine cups, gaps, and grays into an eyesore inside three seasons. I have installed miles of fence, and the difference always traces back to the panel style, the lumber, and whether the posts were set right. This guide covers the styles worth buying, the woods worth paying for, and what the whole project actually costs per foot.
Privacy panels are pre-assembled sections, typically 6 or 8 feet wide, that span between posts. Buying panels speeds installation over building board by board, but the panel style you choose determines how much privacy, wind resistance, and longevity you get.
Common Privacy Panel Styles
Not all privacy fences are equally private, and the style changes both the look and how the fence handles wind. Know the main types before you buy.
- Dog-ear: The most common and affordable, with boards whose top corners are clipped at 45 degrees. Full privacy, simple, and budget-friendly.
- Board-on-board (shadowbox): Boards alternate on opposite sides of the rails so there are no gaps even as the wood shrinks, and the fence looks finished from both sides. More lumber, more cost, better longevity of privacy.
- Flat-top and framed: A clean straight top, often with a top cap rail, for a more refined, modern look.
- Lattice-top: Solid privacy panel below with a decorative lattice section on top for light and airflow.
- Horizontal: Boards run horizontally for a contemporary look; requires straight, stable boards and sturdier posts.
Board-on-board is my recommendation for true long-term privacy because wood always shrinks as it dries, and a solid side-by-side panel that looks tight on install day will show daylight gaps within a year. The overlapping boards of a shadowbox design hide that movement.
Choosing the Right Wood
The species sets the ceiling on how long the fence lasts and how it weathers. Three woods cover most privacy fences.
Pressure-treated pine is the budget workhorse, chemically treated to resist rot and insects, widely available, and the cheapest option, though it can warp or cup if installed wet and greener boards need a season to dry before staining. Western red cedar is the premium mid-range choice: naturally rot and insect resistant, dimensionally stable, and beautiful, weathering to a soft silver-gray if left unsealed. Redwood offers similar natural durability with a rich color at the highest price and limited regional availability. For most homeowners, cedar hits the sweet spot of longevity and looks; pressure-treated pine wins on pure budget if you seal it.
Standard Sizes and Layout
Privacy fences follow predictable dimensions that make planning easy. Panels are typically 6 feet wide (to match 8-foot post spacing on center) or come as 8-foot sections, and the standard privacy height is 6 feet, though 4-foot and 8-foot options exist where local code allows. Check your municipality and HOA first, since many limit backyard fences to 6 feet and front-yard fences to 3 or 4 feet.
Posts are usually 4-by-4 lumber set 8 feet on center, with 4-by-6 posts for taller 8-foot fences or windy sites. Rails run horizontally between posts, two rails for a 6-foot fence and three for an 8-foot fence, to keep the boards from bowing. Leave the bottom of the boards 2 inches above grade so they do not wick ground moisture and rot. Plan gate openings at 3 to 4 feet for walk gates and 10 to 12 feet for a double drive gate.
Installing Privacy Fence Panels
Solid posts are the foundation of every fence that stays straight, so this is where the work matters most. Set posts in holes dug one-third of the post height deep plus 6 inches for gravel, so a 6-foot-above-grade fence wants posts about 8 feet long set roughly 2 feet deep, below your local frost line. Add 6 inches of gravel for drainage, set the post plumb, and pour concrete, crowning it above grade so water sheds away from the wood.
Let the concrete cure a day or two before hanging panels or attaching rails and boards. Keep the fence line taut with a mason’s string so posts align, and check each post plumb in two directions before the concrete sets. When mounting pre-built panels, use galvanized or coated brackets and fasteners; standard steel rusts and streaks the wood. Keep the whole run level or stepped evenly on a slope, either racking the panels to follow the grade or stepping them in even increments.
What It Costs
Budget by the linear foot, materials plus labor. Installed by a contractor, a wood privacy fence typically runs $25 to $50 per linear foot depending on wood species, style, and site conditions. That puts a 150-foot backyard fence somewhere between $3,750 and $7,500 installed.
- Pressure-treated pine: roughly $15 to $30 per linear foot installed.
- Cedar: roughly $25 to $45 per linear foot installed.
- Redwood: roughly $35 to $60 per linear foot installed.
DIY cuts the labor, which is often half the total, but demands you dig and set posts correctly, the part most likely to go wrong. Pre-built panels save assembly time. Add for gates, which run $150 to $500 each in materials, and for post concrete, gravel, and stain. Factor in about a 10 percent waste allowance on boards and hardware.
Pre-Built Panels Versus Building on Site
You have two ways to raise a privacy fence, and the choice affects both speed and fit. Pre-built panels arrive assembled in 6-foot or 8-foot sections that you hang between posts, which is far faster since one panel covers a whole bay at once. They are the right call for a long straight run on flat ground and for DIYers who want to move quickly, though the fixed panel width means you must space posts to match, and they can be awkward to rack on a slope.
Building stick by stick, setting posts, attaching rails, then nailing individual boards, takes longer but gives you total control. You can follow an uneven grade smoothly, adjust for a wall or obstacle, and choose exact board spacing and a board-on-board pattern that pre-built panels may not offer. Custom building also lets you use higher-grade lumber than the often-thin boards in economy panels. For most backyards, pre-built panels win on speed; for sloped lots, custom looks, or premium materials, build in place.
Dealing With Slopes and Property Lines
Two site issues trip up more fence projects than any material choice: grade and boundaries. On a sloped yard you have two methods. Racking lets the panel’s boards pivot slightly so the top follows the grade in a continuous line, which works for gentle slopes and keeps a clean look. Stepping holds each panel level and drops it down in even increments from post to post, which suits steeper grades but leaves triangular gaps at the bottom you may need to close with a kickboard or fill.
Before any of that, confirm exactly where your property line runs, ideally with a survey or by locating the pins, because building even a few inches over the line invites a dispute or a forced teardown. Many jurisdictions require the fence set back a few inches inside your line, and the finished, good-looking side traditionally faces your neighbor. Call 811 to mark utilities before you dig, check setback and height rules with your city and HOA, and talk to neighbors early, especially on a shared boundary where splitting the cost is common. Sorting out the line and the slope before you set a single post saves the most expensive mistakes in fencing.
Sealing and Maintenance
Even rot-resistant wood lasts far longer with protection. Once the fence is dry, pressure-treated boards after a season and cedar after a few weeks, apply a penetrating stain-sealer with UV inhibitors. Sealing preserves the wood’s color and blocks the moisture cycling that causes cupping and cracking; left bare, even cedar grays and checks over time.
Reseal every two to three years, and inspect the posts annually at ground level, where rot starts. Keep vegetation and mulch off the boards, and re-nail or re-screw any board that works loose before it warps. A quality panel of cedar, set on properly concreted posts and resealed on schedule, delivers 20 years or more of full privacy. Cutting corners on the posts or skipping the sealer is exactly how wood privacy fence panels end up gray, gapped, and leaning a decade before their time.
