Split rail fencing is one of the oldest fence styles in North America — and one of the few that looks better with age. The AFA's Fence Installation School describes it as "a rustic style fence constructed of post and rails. Post and rails can be hand split/sawn, natural shaped or machine rounded."
It's not for everyone — it provides no privacy and minimal security. But for property delineation, rural aesthetics, and decorative boundary marking, nothing else comes close.
What Is Split Rail Fencing?
Split rail is a post-and-rail system with no pickets, panels, or infill. Two or three horizontal rails fit into notches or holes in upright posts. The rails are typically split from logs (traditional) or machine-milled to a rough-hewn profile (modern).
Per the AFA, "the typical number of rails may vary depending on height requirements. There are many different styles of split rail type fence depending on geographical area."
Common configurations:
- 2-rail: 36–42 inches tall. Decorative boundary marking.
- 3-rail: 48–54 inches tall. Property lines, horse/livestock containment (with wire mesh).
- 4-rail: 60+ inches. Large animal containment.
Materials
Cedar
The most popular split rail material nationwide. Western red cedar's natural rot and insect resistance makes it ideal for a fence style that's meant to weather naturally. Cedar split rail weathers to a silver-gray patina over 2–3 years.
Black Locust
Extremely dense and naturally rot-resistant — often called the "fence post wood" because it can last 25–30 years in ground contact without any treatment. Primarily available in the eastern U.S. Hard to find west of the Rockies.
Pressure-Treated Pine
The budget option. Treated pine split rail costs 30–40% less than cedar but lacks the natural weathering aesthetic. The chemical treatment provides rot and insect resistance comparable to cedar. See our wood species guide for species comparisons.
Composite/Vinyl Split Rail
Some manufacturers offer composite and vinyl versions that mimic the split rail look. They won't weather naturally but require zero maintenance. Significantly more expensive than wood.
Split Rail Fence Costs
| Material | Cost Per Foot (Installed) |
|---|---|
| Cedar (2-rail) | $12–$22 |
| Cedar (3-rail) | $16–$28 |
| Pressure-treated pine (2-rail) | $8–$16 |
| Pressure-treated pine (3-rail) | $12–$22 |
| Black locust (3-rail) | $18–$30 |
| Vinyl/composite split rail | $20–$35 |
Split rail is the cheapest wood fence style per linear foot — significantly less than privacy fencing. For full pricing comparison, see our cost per foot guide.
Adding Wire Mesh
The AFA notes that "wire mesh or fabric will/can be attached to post and rail to provide for child or pet containment." This is the most common modification to split rail fencing.
Options:
- Welded wire mesh (2×4" openings): Standard for pet containment. Attach to the inside of the rails with fence staples. Add $2–$4/ft.
- Chicken wire/poultry netting: Smaller openings for small dogs, rabbits. Less structural. Add $1–$2/ft.
- Chain link fabric: Maximum security on a split rail frame. Uncommon but effective. Add $4–$7/ft.
- Horse/no-climb wire (2×4" mesh, heavier gauge): Specifically for equine fencing — won't catch hooves. Add $3–$5/ft.
Installation
Split rail installation is simpler than most fence types:
- Mark the fence line and post locations (typically 8–10 feet apart for standard rails)
- Dig post holes per AFA standards — depth of one-third the total post length. See our post depth guide.
- Set posts in concrete or gravel. Gravel drainage works particularly well for split rail because the lighter fence load doesn't require maximum lateral strength. See our post setting methods.
- Insert rails into pre-cut mortise holes in the posts
- Attach wire mesh if desired (staple to inside face of rails)
Slopes: Split rail handles slopes naturally. The rails follow the grade without stepping — this is the "contouring" method described in our fence on slope guide, and it's where split rail excels.
Best Uses
- Property line marking in rural, suburban, and semi-rural settings
- Decorative boundaries for front yards (under most height limits without a permit)
- Horse and livestock fencing (with appropriate wire mesh)
- Pet containment (with welded wire mesh)
- Landscaping accents along driveways, gardens, and pathways
- HOA-friendly front yard fencing in communities that restrict privacy fencing
Markets where split rail is popular: Denver (mountain/western aesthetic), Nashville (rural Tennessee style), Raleigh and Charlotte (suburban property lines), Portland (natural aesthetic).
What Split Rail Can't Do
- No privacy. Wide-open design provides zero visual screening.
- No security. Easy to step over or through (even with 3 rails).
- No wind protection. Wind passes straight through.
- Not for pools. Doesn't meet barrier requirements — see our pool fence guide.

Frequently Asked Questions
How long does split rail fence last?
Cedar: 15–20 years. Black locust: 25–30 years. Pressure-treated pine: 12–18 years. All without any maintenance. With occasional post replacement, a split rail fence line can last indefinitely. See our lifespan guide.
Does split rail fence need a permit?
In most cities, split rail under 4 feet doesn't require a permit. Over 4 feet (3-rail and taller) may require one depending on your jurisdiction. Check our permit guide.
Can I install split rail fence myself?
Split rail is one of the most DIY-friendly fence types. No panel alignment, no picket spacing, simple post-and-rail assembly. Our DIY vs. pro guide covers the decision, but split rail is firmly in DIY territory for most homeowners.
How do I keep dogs from going through split rail?
Add welded wire mesh (2×4" openings) stapled to the inside of the rails. For small dogs, use smaller mesh or chicken wire. Cost: $1–$4/ft added.
