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 16x20 ft A-Frame Pavilion Plan lands in the $11,950–$18,700 range for materials in Pressure-Treated Pine, while the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan runs $3,375–$5,275 in Mahogany. The second plan is approximately 254% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Pressure-Treated Pine over Mahogany and the difference in cubic concrete volume between 6 and 4 footings.
Labor & difficulty
At ~141 hours, the 16x20 ft A-Frame Pavilion Plan is rated Advanced. The 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan takes ~107 hours and is rated Advanced. The labor delta is roughly 34 hours, or one extra working day on the 16x20 ft A-Frame Pavilion 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 320 sq ft vs 144 sq ft, you are choosing between a full outdoor room and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 16x20 ft A-Frame Pavilion Plan needs a clear area of approximately 20×24 ft and the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan needs 16×16 ft.
Material & durability
The 16x20 ft A-Frame Pavilion Plan is built from Pressure-Treated Pine, while the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan calls for Mahogany. 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, 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan is the clear budget pick. 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.
