Custom Size 11ft x 17ft White Rectangle Sun Shade Sail - UPF50

In this review the focus is on a custom-size white rectangle shade sail designed for patios and outdoor spaces. The reviewer found it best for homeowners or small businesses who want solid sun protection with a tailored fit; the single biggest reason to buy is its combination of 95% UV blockage and heavy-duty construction that yields meaningful temperature reduction while remaining breathable. The sail is presented as a practical, durable canopy solution rather than a decorative piece, and the review covers installation notes, durability, and when a custom edge or straight side option might be preferred.

Key Features

• 95% Sun Protection: Blocks up to 95% of harmful UV rays for safer outdoor time under a UPF50+ canopy.
• 200 GSM HDPE Fabric: The heavy-duty material resists wear and provides commercial-standard strength for longer service life.
• Temperature Reduction: Lowers ambient temperature by up to 15 degrees compared to unshaded areas for a noticeably cooler sitting area.
• Custom Fit: Sails are made to measure from D-ring to D-ring so the canopy fits specific dimensions like 11' x 17' without excess material.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching reduce fraying and improve attachment reliability.
• Permeable Design: The fabric is water and air permeable, so it sheds some rain and allows breeze while maintaining shade.

Who It's For

This shade sail is aimed at homeowners, renters with permission to mount hardware, and small commercial properties that need reliable, custom-sized sun protection over a patio, play area, or seating zone. It suits anyone who values measured fit and a durable, utilitarian canopy that cuts heat and sun exposure without blocking airflow.

People who should look elsewhere include buyers seeking a fully waterproof awning or a decorative fabric with translucent colors; this product focuses on UV protection and temperature reduction rather than complete rainproofing or ornamental design options.

Pros & Cons

Pros

• High UV blockage provides strong sun protection for prolonged outdoor use.
• Durable 200 GSM HDPE construction with reinforced edges and stainless steel D-rings increases longevity.
• Custom sizing ensures a neater, tailored installation that fits specific rooflines or post layouts.
• Air and water permeability helps prevent wind load and pooling compared with solid tarps.

Cons

• Not fully waterproof, so it may not keep heavy rain entirely out from underneath the canopy.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water permeable, so it sheds light rain and reduces pooling but is not a fully waterproof tarp for heavy downpours.

How should I measure for a custom fit?
Measure from D-ring to D-ring for the exact size; allow recommended corner gaps of at least 0.5 ft or follow guidance to reduce by 1 to 1.5 ft per side as needed for tension.

What hardware is included or recommended?
The sail includes reinforced stainless steel D-rings; use compatible mounting kits and sturdy anchor points like posts, walls, or trees for safe installation.
