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 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) lands in the $1,350–$2,100 range for materials in Cypress, while the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan runs $5,150–$8,075 in Western Red Cedar. The first plan is approximately 285% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Western Red Cedar over Cypress and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~57 hours, the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) is rated Intermediate. The 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan takes ~24 hours and is rated Beginner. The labor delta is roughly 33 hours, or one extra working day on the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress). If you are newer to outdoor woodworking, the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 100 sq ft vs 400 sq ft, you are choosing between a focal-point garden structure and a full outdoor room. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) needs a clear area of approximately 14×14 ft and the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan needs 24×24 ft.
Material & durability
The 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) is built from Cypress, while the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan calls for Western Red Cedar. 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, 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) 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.
