Custom Size 13ft x 20ft x 23.9ft Blue Right Triangle Sun Shade Sail

In this review the Amgo custom size right triangle shade sail earns recommendation for homeowners and small businesses seeking a tailored, heavy-duty canopy that blocks sun without trapping air. The single biggest reason to buy is its combination of a true custom fit and durable 200 GSM high density polyethylene fabric that delivers up to 95% UV blockage, making it a practical option for patios, play areas, and outdoor seating. Installation is flexible enough for DIYers willing to measure between D-rings carefully, and the included reinforced edges and stainless D-rings suggest a product built to last.

Key Features

• Material and protection: 200 GSM HDPE fabric blocks up to 95% of UV rays for safer outdoor use and long-term color retention.
• Heat reduction: The sail lowers temperatures by up to 15 degrees compared to unshaded areas, improving comfort beneath the canopy.
• Custom sizing: Made to order to D-ring measurements so the sail fits specific areas and reduces gaps or sagging common with off-the-shelf sizes.
• Durability: Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity in sun and wind-exposed locations.
• Air and water permeability: The breathable weave lets air and some water pass, reducing uplift in wind and preventing puddling after light rain.
• Simple installation guidance: Instructions recommend corner gaps and measurement reductions to help tension the sail properly and maintain performance.

Who It's For

The sail suits homeowners, cafes, and property managers who need a precise right triangle shade for patios, decks, playgrounds or outdoor dining areas and who value a heavy-duty, commercial-standard fabric. It is especially useful when existing mounting points like trees, poles or walls require a custom-cut sail to avoid excessive sag or awkward tension points.

Those who should look elsewhere include buyers who want a waterproof awning or a rigid frame canopy, as the fabric is water permeable and performs as a shade rather than a rain shelter. Also, buyers who prefer plug-and-play kits with fixed standard sizes may find custom measurement and cutting more involved.

Pros & Cons

Pros

• High UV protection and measurable temperature reduction for noticeably cooler shaded areas.
• Constructed from 200 GSM HDPE with reinforced stitching and stainless D-rings for commercial-grade durability.
• Custom sizing provides a tailored fit so the sail integrates cleanly with existing attachment points.
• Breathable material reduces wind uplift and prevents water pooling after light rain.

Cons

• Some buyers may find final dimensions smaller than expected unless D-ring to D-ring measurements are precise.
• Not a fully waterproof solution, so it does not replace rigid or coated awnings for heavy rain protection.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring along the planned attachment points and follow the seller guidance about leaving or reducing corner gaps to get proper tension.

Is this sail waterproof?
No, the 200 GSM HDPE fabric is water and air permeable so it sheds heat and reduces water pooling but is not a waterproof rain canopy.

How durable are the fittings?
The sail uses stainless steel D-rings and reinforced, double-stitched edges for commercial-level durability in sun and wind exposure.
