Shade sail post ideas! A shade sail is a nifty way to keep cool in your favorite sunny spot. And they’re relatively inexpensive! However, to make them work effectively and safely, you need sturdy shade sail posts to mount them on. 

To cast shade optimally, semi-permanent shade sails must be taut between solidly secured shade sail posts. Temporary shade sails don’t need quite as much tension, but they do need rigid and stable sail posts to fly right. 

We’ve dived deep and bagged a bunch of solid DIY shade sail post ideas to get you sitting pretty in outdoor summer coolness!

19 Solid DIY Shade Sail Post Ideas

garden protected by shade post sails and an umbrella with sturdy privacy fence
Here you see a lovely party area and garden protected by a DIY shade sail project. In this article, we’re going to show you how to build something similar. Without breaking the bank! Before diving into the best shade sail project ideas, we also want to share a few of our must-know tips to ensure your shade sail functions optimally.

The best DIY shade sail post ideas help ensure optimal shade, functionality, and longevity from shade sails. A rigid steel or wood post with a solid foundation will safely suspend a shade sail and prevent post failure when tension loads, rain, or strong winds act on the shade sail and sail post.  

  • Shade sails offer a novel and easy DIY alternative to traditional outdoor sun protection such as fixed awnings, pergolas, and gazebos. 
  • A shade sail makes stylish sense if you’re looking for a versatile, semi-permanent shade solution.

Bona fide shade sails must get tensioned properly, sloped or hypar, securely anchored to existing home infrastructure (trees, too!), and, more often than not, attached to dedicated shade sail posts

Ideally, shade sail posts should be:

  • Make the sail post from a rigid material to withstand high-tension loads from the shade sail.
  • Anchor the sail solidly for protection against strong winds, rain, and hail.
  • Allow for easy and quick demounting of the shade sail when you expect snow or hurricanes. 
  • Rust, rot, and termite resistant.
  • Fit with rustproof shade sail hardware (eye bolts/eye lags, turnbuckles, pulleys, and cleats) to adjust shade sail tension and height.
  • Lean away from the center of the shade sail at a 5° to 15° angle
  • Allow the shade sail to demount easily in the snow season and for cleaning/maintenance procedures. 

Installing a premium shade sail post will invariably require digging a hole and pouring concrete.

If all of these considerations seem overzealous to cast a pool of shade, read on!

  • There are straightforward ways to erect a lightweight shade sail using posts that don’t need digging, concrete, or fancy rigging hardware.

Before we look at the recommended specifications for various shade sail posts, let’s get into the selection of shade sail post ideas – from the semi-permanent to the light-duty and temporary!

1. Easy to Hoist and Demount 3-Point Shade Sail Post Idea

How to Set Up an Easy Hoist Shade Sail
Here’s one of our favorite sunshade sails for your backyard or outdoor space. PrimroseTV produced a straightforward tutorial that shows how to establish a triangle sail without fuss. They also demonstrate how to position your shade sail fixings to create a 30-degree slope. If you follow their tips, their sun sails will block plenty of shade!

Here’s an easy DIY shade sail post for a garden deck from PrimroseTV that provides solid support for the shade sail. And it is fully demountable!

The design makes it super-quick to get the poles in or out of the ground and the shade sail hoisted and struck (that’s ‘up’ and ‘down’ in nautical terms) when the weather changes.

  • A dramatically-sloped triangular shade sail gets supported by a tree stump. Two galvanized 2-inch steel posts also offer support. The posts slide into PVC pipe sleeves that rest in deep concrete ground anchors.
  • The steel posts have pulleys, cam cleats, and dock cleats to adjust the sail height without worry.

This idea makes for a relatively easy DIY shade sail post. And the result is ergonomic and responsive to cast shade where and when you need it!

2. Shade Sail Combo with Steel Posts In Concrete

Rob: Shade sails, Ep 43 (22.11.13)
Check out another excellent shade sail canopy method. It’s perfect if you have patio furniture needing reliable sunlight protection. This custom shade sail is also one of the most economical options on our list and still offers excellent protection from the hot summer sun.

Large outdoor entertainment areas generally need more than one shade sail to provide a comfortable shade footprint. Here’s an installation by Australia’s Great Home Ideas that hoists rectangular and triangular shade sails using two 4-inch steel posts.

  • The galvanized steel posts sit in concrete with drain holes at the base of the posts.
  • Standard shade sail hardware works nicely to keep the shade sails tensioned appropriately.
  • The builder in this video recommends giving the posts five days to set in the concrete before installing the shade sails.

With steel posts solidly anchored and tensioned, those shade sails can fly in strong winds without ongoing fuss!

3. Two 4×4 Wood Posts with Simple Rigging for a Square Shade Sail

How to Install A Shade Sail - The Easy Way!
Koi love a little afternoon sun and occasional light rain. But they don’t like boiling in the direct sunlight all afternoon! So DoItYourselfDad shares some excellent cheap shade sail tips for covering a backyard pond, koi pond, or any backyard space needing ambient shade. The tutorial is fast-paced, and the hardware kit and gear seem relatively low-cost. Required materials include a paracord, rope cleat, shade sails, and eye bolts.

Fish need shade too! Here’s a neat shade sail post idea for a koi pond using a rectangular shade sail suspended by two pressure-treated four-by-four wood posts by DoItYourselfDad

The idea uses suitably deep holes and quick-drying pre-mix concrete.

The tensioning of the shade sail works simply by using the following components.

The quick-release clam cleats allow the owners to quickly and easily lower and remove the shade sail when they want to prune trees near the shade sail posts.

Low cost, ergonomic, and sturdy!

4. Two 6×6 Wood Posts with Turnbuckles for a Deck Shade Sail

How to Install Shade Sails | Mitre 10 Easy As DIY
Mitre 10 New Zealand produced one of the most in-depth sunshade sail project tutorials we encountered. They teach how to build a low-cost and chic-looking pergola as a home attachment. It seems like a low-cost option for nifty outdoor shades. The tutorial also shares excellent summer shade sail insights about triangle shade sails, sail post placement, how to position and hang shade canvas, et cetera.

A raised deck adjoining your house makes an ideal anchor point for a shade sail. Or two! Watch as Mitre Ten New Zealand demonstrates with their DIY shade sail post tutorial.

Using 6” x 6” glue-laminated wood posts, the builder secures the posts in a 4-feet deep hole with concrete. For extra stability, the posts secure to the deck with steel brackets and lag screws.

When tensioning the shade sail, D-shackles and four turnbuckles are used, along with lengths of chain that extend the tensioning system’s reach from the sail to the posts.

The post foundation holes seem professionally executed, the posts are super-strong, and the recommended tensioning hardware creates a no-nonsense taut shade sail for a durable and crisp shady experience!

5. Wood Posts and Cross Beams for Four Triangular Shade Sails

Shade Sail👀  This is How you do it!
We love these shade sail post ideas by Little About a Lot. The shade sail project erects several triangle shade sails in unison and offers elite sunlight protection for a driveway, walkway, front yard porch, or patio. It looks cooler already!

Little About A Lot avoids digging deep holes into his garden by replicating a basic pergola frame design. They use wood cross beams to help three shade sail posts support four triangular shade sails.

With 6” x 2” wood beams held aloft by 6” x 6” wood beams (joined using steel brackets), the design creates tension in the shade sails using lag hooks, chains, carabiners, and turnbuckles. Very clever.

Despite being a labor-intensive DIY project, the design has proved itself over several years – stormproof and solid!

6. Hinged and Cross-Braced Shade Sail Posts with Back Stays

How to Install Shade Sails - Installation Ideas and DIY Set Up Tutorial
The Cuban Redneck goes into intricate detail with their shade sail post-presentation. The tutorial notes several anchor positions to help maintain shade sail tension. The materials needed to follow along aren’t that expensive. Materials of note include four two-by-fours, eye bolts, T-hinges, and shade sails. Overall, the project is surprisingly frugal. And effective! (It also looks like these could transform into retractable awnings with a few tweaks.)

Here’s an innovative approach to achieving post lean without sinking the sail posts into concrete, courtesy of The Cuban Redneck.

Instead of relying on standard timber posts, this idea laminates and screws together four two-by-fours to create two shade sail posts. It seems less prone to bending under duress.

Two concrete slabs rest adjoining a concrete patio to attach two T-hinges that secure the posts to the patio foundation.

  • A steel crossbar adds lateral stability to the posts.

With the posts on hinges, ratchet straps acting as backstays are connected to the top of the posts and the concrete slabs to adjust tension in the sail!

Ingenuity or DIY folly? You be the judge!

How to Install 10 x 10 Shade Sail
Drone Flyers Multirotor built a snug and sleek-looking shade sail project using a ten-by-ten shade sail and a few four-by-fours. The cost for all sail shade materials was less than $200. It seems to offer lots of sunlight protection. It also looks elegant – and we noticed the beige sail post matches the deck. Nice!

Here’s another lovely shade sail post idea that uses cam cleats instead of turnbuckles to tension the shade sail, a patio cover by Drone Flyers Multirotor.

Two 4x4s are set in concrete on the lawn at an angle leaning away from the deck. The shade sail is suspended and tensioned with ropes running through pulleys and cam cleats.

  • The timber posts match the earth tones of the square shade sail, which is installed with a gentle slope to allow rainwater to run off!

low-cost and sensible shade sail post idea!

10. Lightweight No-Dig PVC and Dowel Sun Shade Posts

Hanging a Sun Shade With Homemade Posts!
This shade sail post idea from The Project Cave is perfect for backyard parties, barbeques, summer get-togethers, banquets, weddings, or picnics. And it’s also agile – you can put it up anywhere. We also love how you don’t need many tools – only a saw, drill, shade sails, and a few PVC pipes.

If you need a temporary sunshade for a patch of lawn in your garden, consider this crafty shade sail post idea from The Project Cave using ¾-inch PVC pipe.

The idea attaches two points of a rectangular shade sail to the branches of a large tree, with the other two corners suspended by eight-foot PVC pipes reinforced with dowel rods.

The tops and bases of the PVC pipes fit with PVC pipe caps equipped with hex bolts to secure guy ropes and steel spikes into the earth.

The stability of the shade sail is made possible via the guy lines and good old tent pegs.

OK. It’s a tarp on poles, but it works perfectly as an occasional shade sail for garden lounging!

11. Budget PVC Pipe and Steel Stake for Koi Pond Sun Shade

Here’s another excellent shade sail post idea for backyard koi or goldfish ponds from Ha Y N Fish Keeper. The video features a special-needs koi without eyes! We think it could use all the support it can get – and hopefully, the shade sail makes the summers more tolerable! This tutorial goes into greater detail than other shade sail post tutorials we’ve seen – and the project cost should be minimal.

Here’s another fishy idea. It’s a cheap and joyous low-effort project to protect koi fish from the sun and predatory birds – presented by Ha Y N Fish Keeper.

A seven-foot PVC pipe with an eyebolt at the top positions over a steel fence stake hammered into hard ground.

  • galvanized hex bolt runs through the PVC pipe. Then through a hole in the stake to secure the pipe to the stake.

With three corners of the shade sail attached with rope to existing walls, the single shade sail post wins points for neatness by using a jam cam to create tension in the shade sail.

It may not look pretty – but it is cost-effective! And the fish won’t complain!

12. Demountable Shade Sail Posts with Fence Top Rail and PVC Sleeves

Sun Sail Shade Install Into Brick
This shade sail post idea from Adam Wellborn is arguably one of the most organized tutorials on our list. It teaches how to establish your shade sail pole layout, list the needed materials, drill into the brick foundation, install anchors, poles, and more. Overall, it’s intricately detailed. And the results look excellent. (We love the cafe lights as a finishing touch!)

If you want a shade sail and its posts removed from your patio during winter, this idea from Adam Wellborn may be the ticket.

Steel fence top rail is cut to three 10’ lengths and dropped into PVC sleeves set in concreted holes adjacent to the patio to support two triangular patio shade sails.

  • Tensioning hardware includes turnbuckles, carabiners, and rope.

PVC pipe end-caps seal the PVC sleeves flush with the soil surface when the steel posts extracts during the off-season.

It is a lightweight seasonal shade solution. But your patio will stay cool with the posts in concreted PVC sleeves and the shade sails tensioned.

13. Strong Shade Sail Posts Using Steel Scaffolding Components

How to Installing a shade sail pole for beginners cheaply
Here’s a thrifty yet tremendously efficient shade sail post project by Nicki Shaw. They promise to show how to install a shade sail post without breaking the bank. The project seems light, agile, and straightforward. And it also looks highly effective!

The big difference between semi-permanent and temporary shade sail posts is how well they stick to the ground. Here’s a great shade sail post from Nicki Shaw that uses scaffolding components.

Nicki uses a scaffolding T-joint to create a bulky base for a scaffold upright shade sail post.

  • The base is attached to the upright, and the post sets in subterranean concrete.

Don’t be intimidated by the result. If Jonty can do it, so can you!

19. Height-Adjustable Shade Sail Post Using Track and Trolley Wheels

Shade Sails Canada Traveller System | Adjust The Position Of Your Shade Sail
We’re wrapping up our list of shade sail post ideas with one of the fanciest designs by Shade Sails Canada. The slick engineering empowers you to adjust your shade sail corners and tension on the fly. It’s perfect for dodging the setting sun. Check it out!

The shade moves across the ground as the sun moves across the sky. This shade-shifting can be annoying if you constantly move furniture around to keep cool!

Can a shade sail post facilitate easy repositioning of the shade sail to cast shade dynamically? Yes, it can. But only if equipped with a track and trolley wheels!

We got the idea from Shade Sails Canada and its Traveller System, a high-end shade sail rig designed to lower and raise a sliding shade sail corner attached to a shade sail post.

Watch the video and then envision a 6” x 6” steel or wood post with a metal strut channel and trolley wheels attached to it.

  • How can you pull the trolley wheels up and down the track? Attach clam cleats above and below the strut channel and braided nylon rope. 
  • Give your shade sail an authentic nautical look by winding a sisal rope around the base of the shade sail posts.

Ingenious, even if we say so ourselves!

Now let’s look at the shade sail spec sheet.

Premium shade sail posts come from galvanized or stainless steel tubing or pressure-treated wood posts. A shade sail post’s rigidity in a solid foundation helps optimum shade sail tension. A shade sail post-lean angle of five to fifteen degrees compensates for post-deflection under extreme load.

  • Best Steel Tubing for Shade Sail Posts

Use 4-inch round or square schedule-40 steel tubing. Galvanized or stainless steel tubing is maintenance-free. 

  • Best Wood for Shade Sail Posts

Pressure-treated laminated 6” x 6” wood posts rated for ground contact are ideal for long-term shade sail installations.

How Deep Must I Dig a Shade Sail Post Hole?

Shade sail post holes should be at least 3 feet deep and 1 foot wide for shade sail areas under 150 square feet. Post holes for large shade sails should be 4-6 feet deep for optimum rigidity and durability. 

What’s the Best Way to Secure Shade Sail Posts In Concrete?

Screw four to six steel lags into the base of the shade sail post to give the concrete more surfaces to adhere to effectively. Rebar fed through holes drilled into the steel base and wood shade sail posts also ensures the posts remain in their concrete anchors.

How Long Must Shade Sail Post Foundation Concrete Cure?

The minimum curing period for concrete is 24 hours. For heavy-duty shade sails and posts, allow the concrete to cure for at least 72 hours before attaching the shade sail and tensioners.

How Much Tension Does a Shade Sail Need? 

Shade sails need to be tensioned to between 150-400 pounds to create a wind-deflecting surface that will ensure the sail’s longevity and the tensioning hardware. A slack shade sail will billow and deteriorate rapidly, while the tensioning hardware will make an unpleasant noise and suffer premature fatigue.

What is the Best Shade Sail Configuration?

Shade sail posts should enable a wind-deflecting ‘hypar’ shade sail configuration where two diagonally opposite corners of a square or rectangular sail-shade are mounted higher than the other two diagonally opposite corners, creating a pitched and triangulated 3D effect.

  • A hypar technique keeps the shade sail taught and allows for runoff (preventing water pooling in the sail).
  • A hypar fitment prevents the shade sail from billowing in windy conditions.
  • A hypar shade sail will last longer than a flat or sloped shade sail.
  • A hypar shade sail installation creates an aesthetically appealing dramatic effect.

We also have some shade sail FAQs to share with you!)

Solid DIY Shade Sail Posts – FAQs 

Building a shade sail post is trickier than most homesteaders think! But no worries. We amassed a lovely list of common shade sail post FAQs you may encounter in your quest to keep the sun out of your eyes!

We hope these shade post insights help you!

What Do You Use for Shade Sail Posts?

Shade sail posts generally use 4-inch tube steel or 6 x 6-inch wood posts. Steel posts should be galvanized or coated with enamel paint. Wood posts must be pressure-treated and rated for ground contact. Tensioning and anchoring hardware should be galvanized or stainless steel.

How Do I Attach a Shade Sail to a Post?

A shade sail should ideally be attached to a post using tensioning hardware such as a turnbuckle or clam cleat. Eyehooks, D shackles, carabiners (quick clips), lag screws, and braided nylon paracord to facilitate optimal tension in the shade sail. Ratchet straps help pull the shade sail into place before the turnbuckle or rope gets affixed to the post.

How Do I Make a Shade Sail Look Good?

The best way to improve the appearance of a shade sail is to keep it taut via the fitment of tensioning hardware and rigging. A hypar fitment of the sail, where two diagonally opposing corners of the shade sail are mounted higher than the opposite diagonal corners, creates a distinctive triangulated 3D look to the shade sail.

How Do I Attach a Shade Sail to a Patio?

A shade sail can be attached to a patio using the house’s Fascia boards as a connection anchor for one side of the shade sail, while posts mounted to the deck using steel brackets and backstays suspend the opposite corners of the shade sail. A pergola-style design also effectively lifts shade sails above a patio or backyard deck.

How Deep Do Posts Need to be for a Shade Sail?

The rule of thumb for sail shade post-hole depth is one-third of the desired height of the post above ground. If a shade sail height of 12 feet is required, the sail post should sit in a hole 4 feet deep. In this example, the shade sail post must be 16 feet long to satisfy the shade sail height requirement.

Why are Shade Sail Posts Angled?

Shade sail posts are angled away from the shade sail center to reinforce the support shade sail structure and prevent slackening of the shade sail. By presenting an additional resistive force to the load established on the sail and post by the tensioning hardware, the angled sail post maintains shade sail tautness. And it helps prevent premature wear or failure of the shade sail and hardware.

Should Shade Sail Posts Be Angled?

For optimum functionality and safety, the shade sail should get angled. The tensile forces created by the shade sail and its tensioning hardware, coupled with wind loads, cause the shade sail post to deflect (bend). A sail post angled at 5°-15° away from the shade sail center will compensate for deflection and minimize slackening of the shade sail.

Land Ahoy!

There you have it, folks! A veritable odyssey across the oceans of shade sail post selection and installation. Whatever your choice of shade sail or shade sails, follow these guidelines for the best possible DIY shade sail post-project – one that will last for a decade or more and always keep you cool!
