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 Cantilevered Pergola Plan lands in the $6,650–$10,400 range for materials in White Oak, while the 12x14 ft Mission Pergola Plan runs $5,450–$8,525 in Redwood. The second plan is approximately 22% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of White Oak over Redwood and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~60 hours, the 12x16 ft Cantilevered Pergola Plan is rated Intermediate. The 12x14 ft Mission Pergola Plan takes ~14 hours and is rated Beginner. The labor delta is roughly 46 hours, or one extra working day on the 12x16 ft Cantilevered Pergola Plan. If you are newer to outdoor woodworking, the 12x14 ft Mission Pergola Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 192 sq ft vs 168 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 Cantilevered Pergola Plan needs a clear area of approximately 16×20 ft and the 12x14 ft Mission Pergola Plan needs 16×18 ft.
Material & durability
The 12x16 ft Cantilevered Pergola Plan is built from White Oak, while the 12x14 ft Mission Pergola Plan calls for Redwood. 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, 12x14 ft Mission Pergola 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.
