Building a Wooden Fence

Materials are where budgets drift, so build a quick mental bill of materials before you buy anything. For a typical 6-foot dog-ear privacy fence, the pickets themselves are often around 5.5 inches wide and 6 feet tall; one common example lists pickets at about 0.59 inches thick by 5.5 inches wide by 6 feet tall.

Rails are commonly 2x4s, and most 6-foot privacy builds feel better with three rails—top, middle, bottom—instead of two, especially in wind. Posts are where you don't cut corners: use a true ground-contact post and plan on a diameter and depth that won't move.

If you're in a freeze zone, frost depth and soil conditions should influence your hole depth—there's no one-size-fits-all number across the country. Cedar and redwood look great and resist rot naturally, but they still need thoughtful finishing if you want them to keep their color.

Pressure-treated pine is tough and usually the most affordable route for pickets, rails, and posts, but it can warp as it dries and it's heavier. Also, pay attention to treatment ratings: above-ground treated boards are not the same as ground-contact boards, and posts set in soil need the stronger ground-contact classification.

If you're staring at a pile of lumber and wondering why some pieces are darker, wetter, or more prone to twist, that's normal—pick the straightest posts you can find and crown your rails consistently. One recent survey listed an 8-foot pressure-treated 4x4 at $11.18, while other retail price lists show higher figures.

Lay out the line and corners. Set temporary stakes a couple feet beyond your corners and pull a tight mason line between them. Measure off the property line where appropriate, and mark your post locations on the ground with paint or flags. A straight run starts with a bright mason line pulled tight between stakes.

Set spacing and check modules. If you're using prebuilt 8-foot panels, your posts must land where the panels land—no improvising later. For stick-built sections, 8 feet on center is common, but tighter spacing can help on tall fences, windy sites, or where the run changes direction.

Dig holes and prep the base. Cut sod cleanly, then dig to your planned depth with a post hole digger or auger. Belling the bottom slightly can help in some soils. Add a few inches of gravel for drainage and tamp it.

Set and brace posts. Drop the post, align it to the string line, plumb it in two directions with a 4-foot level, and brace it with scrap boards so it cannot move. This is the difference between a clean build and a crooked one.

Add concrete and lock in alignment. Fast-setting mixes can be convenient, but they demand preparation. One widely sold fast-setting concrete mix is designed to set hard in about 20 to 40 minutes, and guidance commonly suggests waiting about 4 hours before applying heavy loads in typical conditions. Translation: have every post braced and checked before you start mixing.

Build the frame, then skin it. Install rails first, keeping the top rail consistent. Then hang pickets using a spacer block for a uniform gap if you want breathing room, or butt them tight for privacy. Finish with caps or trim if you want a cleaner look and better water shedding.

On the plus side, wood is forgiving to work with using common tools, it's easy to customize, and repairs are straightforward—swap a picket, replace a rail, move on. You can build exactly the fence you want without waiting for custom orders or dealing with proprietary hardware systems.

On the downside, wood moves with moisture and sun; it can warp, check, and split. Finishes fade. Fasteners can stain boards if they're not suited for exterior use. And if you skip drainage at the base or use the wrong treatment rating on posts, you'll shorten the life of the fence no matter how pretty it looked on day one.

Pressure-treated lumber needs time to dry before you apply most stains or sealers, and even after treatment, wood is still wood—it will weather, gray, and show age. But unlike vinyl or metal, wood is easy to repair with basic tools, and every board is replaceable without tearing down sections.

A well-built wooden fence isn't about perfection—it's about repeatable habits: measure from a line, set posts right, brace them, and build in a sequence that doesn't fight you. Once you've done one run cleanly, the next projects around the house get easier too.
