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 12x16 ft 5-Point Overlapping Shade Sail Frame Plan lands in the $3,125–$4,875 range for materials in Redwood, while the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan runs $3,375–$5,275 in Mahogany. The first plan is approximately 8% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Mahogany over Redwood and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~21 hours, the 12x16 ft 5-Point Overlapping Shade Sail Frame Plan is rated Beginner. The 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan takes ~107 hours and is rated Advanced. The labor delta is roughly 86 hours, or one extra working day on the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan. If you are newer to outdoor woodworking, the 12x16 ft 5-Point Overlapping Shade Sail Frame Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 192 sq ft vs 144 sq ft, you are choosing between a generous patio cover and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 12x16 ft 5-Point Overlapping Shade Sail Frame Plan needs a clear area of approximately 16×20 ft and the 12x12 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan needs 16×16 ft.
Material & durability
The 12x16 ft 5-Point Overlapping Shade Sail Frame Plan is built from Redwood, 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, 12x16 ft 5-Point Overlapping Shade Sail Frame Plan is the faster build. 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.
