Custom Size 7ft x 20ft Blue Rectangle Sun Shade Sail - UPF50

In this review of the 7' x 20' blue rectangle sun shade sail, the bottom line is simple: it is best for homeowners or small commercial spaces that need a durable, customizable canopy to cut sun exposure and lower surface temperatures. Built from 200 GSM HDPE with advertised 95% UV blockage and stainless steel D-Rings, this shade sail stood out for its balance of heavy-duty construction and practical install flexibility. It is a straightforward option when a tailored fit and long-term outdoor use are priorities.

Key Features

• 95% UV Blockage: The 200 GSM HDPE fabric is designed to block up to 95% of harmful UV rays for safer outdoor use.
• Temperature Reduction: The sail reduces ambient temperature by up to 15 degrees compared to unshaded areas, making patios and play areas noticeably cooler.
• Custom Size Fit: Measurements are taken from D-ring to D-ring so the canopy can be made to fit specific layouts and mounting points precisely.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-Rings add strength and resistance to fraying for longer service life.
• Flexible Installation: Can be attached to trees, roofs, walls or poles; recommended corner gaps and adjustments are provided for proper tensioning.
• 3-Year Assurance: A three-year assurance is included, which provides added confidence for extended outdoor exposure.

Who It's For

This shade sail suits homeowners, childcare providers, and light commercial venues looking for a tailored sun canopy to protect seating, play spaces or outdoor work areas. The custom sizing option makes it useful for oddly shaped or specific roof-to-tree spans where off-the-shelf sails do not fit.

It is less appropriate for those needing a fully waterproof awning or for very large event coverage where multiple sails and complex anchoring would be required; buyers seeking a rigid, weatherproof roof should look for hard-canopy systems instead.

Pros & Cons

Pros

• High UV protection from the 200 GSM HDPE fabric helps reduce sun exposure for people and furniture.
• Temperature drop of up to 15 degrees improves comfort under the canopy on hot days.
• Stainless steel D-Rings and reinforced edges increase durability for regular outdoor use.
• Custom sizing and straight-edge options mean a tailored fit for unique installation sites.

Cons

• Not a fully waterproof canopy; the fabric is water and air permeable, so it will not keep heavy rain fully out.
• Installation requires planning for corner gaps and proper tensioning, which may be tricky for some DIYers.

Frequently Asked Questions

Is this shade sail waterproof?
Answer. The fabric is water and air permeable, so it sheds light rain but is not a fully waterproof canopy for heavy storms.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring at the points where you will attach the sail; the manufacturer uses those dimensions to tailor the sail to your space.

What clearance is needed at the corners?
Answer. For optimal tension allow at least 0.5 ft between D-Rings and poles, or reduce by 1 to 1.5 ft per side if needed when installing.
