If you have narrowed your shortlist to two specific designs, this is exactly the kind of decision where a side-by-side spec view saves a weekend of second-guessing. Both plans below are complete, code-aware DIY builds, but they differ on the things that matter for a backyard project — total cost, raw labor hours, footprint, and the wood species on the cut list.

Cost & budget
The 12x6 ft Horizontal Slat Privacy Screen Trellis Plan lands in the $825–$1,275 range for materials in Cypress, while the 10x8 ft Vertical Board Privacy Screen Trellis Plan runs $650–$1,025 in Pressure-Treated Pine. The second plan is approximately 24% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Cypress over Pressure-Treated Pine and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~126 hours, the 12x6 ft Horizontal Slat Privacy Screen Trellis Plan is rated Advanced. The 10x8 ft Vertical Board Privacy Screen Trellis Plan takes ~144 hours and is rated Advanced. The labor delta is roughly 18 hours, or one extra working day on the 10x8 ft Vertical Board Privacy Screen Trellis Plan. Both plans require the same skill level, so the deciding factor is footprint and aesthetics rather than your comfort with carpentry.
Footprint & site fit
At 72 sq ft vs 80 sq ft, you are choosing between a focal-point garden structure and a focal-point garden structure. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 12x6 ft Horizontal Slat Privacy Screen Trellis Plan needs a clear area of approximately 16×10 ft and the 10x8 ft Vertical Board Privacy Screen Trellis Plan needs 14×12 ft.
Material & durability
The 12x6 ft Horizontal Slat Privacy Screen Trellis Plan is built from Cypress, while the 10x8 ft Vertical Board Privacy Screen Trellis Plan calls for Pressure-Treated Pine. The species choice drives the cost delta and the maintenance schedule. Pressure-treated southern yellow pine is the cheapest and most rot-tolerant for in-ground posts; western red cedar is the DIY favorite for visible parts; redwood and white oak are heritage choices that command a premium.
Verdict
For a builder weighing these two specifically, these two plans are close in cost and effort — your choice comes down to style and footprint. If both fit your budget and yard, default to the design whose style language matches the rest of your house — a Craftsman bungalow looks awkward beside a modern slatted pergola, and vice versa.
