Horizontal Fence Pros and Cons: Is It Worth the Extra Cost?
A horizontal board fence usually costs more than a vertical one of the same material — and manufacturer specs show why: several horizontal systems allow a shorter span between posts, which means more holes and more concrete over the same fence line.

Horizontal fencing usually costs more to install than a vertical fence of the same material — mainly because some horizontal systems allow a shorter unsupported span between posts than the standard 8 ft vertical panel, which means more post holes and more concrete over the same fence line. Vinyl horizontal privacy panels, for example, are sold at 6 ft wide rather than the 8 ft width Barrette uses for its vertical panels. Composite and aluminum horizontal systems keep the usual 8 ft spacing, but composite adds hardware (an aluminum top-rail insert, an aluminum bottom rail, and L-channel retainers at every post) that a vertical picket panel doesn’t need.

What counts as a ‘horizontal fence,’ and why it usually costs more
A horizontal fence runs the boards side to side instead of up and down. It’s available in the same materials as a standard privacy fence — wood, vinyl, composite and aluminum — so it’s a style choice layered on top of a material choice, not a separate product category.
The extra cost homeowners usually hear about isn’t really about which direction the boards run. It’s that several horizontal board systems can’t span as far between posts as a standard vertical panel can, per the manufacturer installation guides below. Fewer feet between posts on the same fence line means more holes, more bags of concrete, and more labor — regardless of how the boards are oriented.
The real cost driver: post count, not board direction
Barrette’s own vinyl fence catalog makes the contrast explicit: its vertical solid-privacy panels are sold in 8 ft widths, but the horizontal privacy panel — same material, same company — is only offered in a 6 ft width. The catalog states the dimensions without explaining the reason, but the practical effect is the same either way: a 6 ft-span material needs more line posts to cover the same fence length than an 8 ft-span material does.
Slipfence’s wood-in-aluminum-channel system is similar: it specifies a 72.5 in clear span between posts (half of a standard 12 ft deck board), just over 6 ft and well short of the 8 ft spacing a standard vertical wood panel typically uses.
Composite and aluminum horizontal systems don’t have this problem. Trex’s horizontal composite fencing is designed for the same 8 ft on-center post spacing as most vertical fences, and Stratco’s aluminum slat screens use 8 ft post centers as well — with the maker stating in its own FAQ that “aluminum achieves greater spans without bracing” compared with other materials (a manufacturer marketing claim, not an independent test, but consistent with the 8 ft spacing stated elsewhere in its installation guide).

Based on the manufacturer specs above — not a quote. A site visit confirms which materials and spans actually fit your fence line.




Other real tradeoffs, not just cost
Sloped lots: Slipfence documents a specific method for stepping horizontal panels down a slope — shortening the gap between level sections and adjusting post spacing — rather than leaving it to guesswork. That’s a genuine practical advantage for a lot that isn’t flat.
Warp risk in heat and humidity: Trex’s installation guide includes a direct tip: “If installing fence in an area of high heat and humidity, consider using a back bracing rail to reduce the risk of warping boards.” That’s an extra part and an extra labor step a standard vertical picket panel doesn’t need, since its boards are short, face-nailed pickets rather than long horizontal spans.
Installation time: Trex recommends a minimum two-person crew for horizontal composite fencing, and its boards must be pre-drilled at the quarter points through the aluminum top-rail insert — one more precise step than nailing a picket to a rail.
