Custom Size 11ft x 16ft x 19.4ft Blue Right Triangle Sun Shade Sail

In this review the focus is on a custom-size right triangle shade sail designed for patios, chicken runs, and small commercial uses. The reviewer found the biggest reason to buy is the combination of 95% UV protection and robust construction that delivers noticeable cooling without a rigid frame. Measured from D-ring to D-ring, this sail is made to order so it fits awkward spaces better than off-the-shelf canopies, and the material and reinforced hardware make it a practical solution for those who need reliable sun blockage and long-term durability.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful rays, providing safer shaded areas for people and pets.
• Temperature reduction: The sail can lower ambient temperature in shaded zones by up to 15 degrees versus unshaded areas, improving comfort in hot weather.
• Custom sizing: Made to order using D-ring to D-ring dimensions so corners align with existing posts, walls or trees for a tailored fit.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and extend service life under regular outdoor exposure.
• Water and air permeable: The HDPE weave lets air and moisture pass through to reduce wind load and prevent pooling during light rain.
• Easy installation: Can be attached to trees, roofs or walls using mounting hardware kits and requires a small gap at each corner for best tensioning.

Who It's For

This shade sail suits homeowners, small business owners and hobby farmers who need a fitted triangular cover that delivers strong UV protection and cooler shade without a framed structure. It is especially useful for patios, pergola add-ons, backyard seating, and runs for animals where airflow and sun protection matter.

Those who should look elsewhere include buyers who need a rigid, waterproof canopy for full rain protection or people who want an exact off-the-shelf square size; the product is water permeable and is made to measure, so it is not a sealed, framed tent substitute.

Pros & Cons

• Custom sizing allows a tailored fit for awkward or irregular spaces.

Our Verdict

This custom right triangle shade sail is a sensible buy for anyone who needs strong sun protection and cooler outdoor space without a rigid frame. Its tailored fit, heavy-duty 200 GSM HDPE fabric and reinforced hardware make it good value for long-term outdoor shading, provided buyers accept that the material is breathable rather than fully waterproof and double-check finished dimensions before ordering.

Frequently Asked Questions

Can this sail be used on a patio attached to a house?
Yes, it can be secured to walls, roofs or nearby posts using appropriate mounting hardware and by measuring from D-ring to D-ring for a proper fit.

Will the sail keep rain out?
The fabric is water permeable and allows moisture to pass through, so it reduces sun and heat but does not act as a fully waterproof awning.

How durable are the corners and attachment points?
The corners use stainless steel D-rings and reinforced, double-stitched edges to reduce fraying and extend service life under normal outdoor conditions.
