Triangle shade sail comparison 2026 for a UK patio
The best triangle shade sails, compared.
Top pick: MissYolo 3 x 3 x 4.3 m triangle Best value: MissYolo 3 x 3 x 4.3 m triangle – Best value at about £11.90, the lowest shelf price in the set, for a stated 3 × 3 × 4.3 m cloth. The 4.5 from 92 reviews is shared with the larger MissYolo. Updated 16.10.2026.
A triangle shade sail is a three-corner outdoor cloth with a ring at each corner, tensioned between walls, posts or a pergola. On amazon.co.uk these eleven ready-made listings are equilateral sails of 2.5 m or 3 m a side, or longer triangles such as 3 × 4 × 5 m and 3 × 3 × 4.3 m. Tell them apart by the cloth the listing names, whether the box includes pad eyes and tighteners or only short ropes, and whether a waterproof title matches the water line underneath. A seller UV percentage is not a test. The NHS still wants shade between 11am and 3pm from March to October, plus clothing and 30 sunscreen with at least 4-star protection. Size, the water limit and the box come first in the [triangle shade sail buying guide](/hub/sun-shades/triangle-shade-sail/sub/triangle-shade-sail-buying-guide). Measure three fixing points and subtract a tension gap. Several listings say leave about 1.5–2 ft, roughly 45–60 cm.

Question 1 of 2
What are the three fixing points?
The best triangle shade sails in detail
Our view
The smaller MissYolo is a dark grey 3 x 3 x 4.3 m sail at about £11.90, the lowest shelf price in this set. It shows the same 4.5 from 92 reviews and the same early review text as the 3 x 4 x 5 m ASIN, and the hero image URL matches too. The size line and the 750 g weight are what separate this file from the larger one. The attribute says HDPE and prints no gsm figure. Shared reviews say tension adjusters are not supplied. A waterproof and full-rain bullet is seller copy, and there is no slope figure. At this price you are buying the cloth and using your own fixings to pull it tight.
Pros
- Lowest price in the set, about £11.90
- 3 x 3 x 4.3 m stated size
- Listed weight 750 g, distinct from the 950 g larger MissYolo
- UV claim over 95% on the listing
Cons
- Star line and review text are shared with the larger size
- No parts list and no gsm figure
- Tensioners not supplied, according to the shared reviews
- No suggested slope
Best for: A low spend on a 3 x 3 x 4.3 m cloth when you already have tensioners and anchors
Less suitable: A review sample that is only about this ASIN, or hardware in the box

Common questions
Why does this share reviews with the larger MissYolo?
Both raw files show 4.5 from 92 and the same early UK review text. The bestseller rank is also the same line. Treat them as one pool.
What size is this ASIN?
The size line is 3 x 3 x 4.3 m and the weight attribute is 750 g. The 3 x 4 x 5 m ASIN is a different size at 950 g.
Is a tensioner in the box?
The shared reviews say tension adjusters are not supplied. The listing does not print a parts list.
Our view
The dark grey MissYolo 3 x 4 x 5 m sail is about £18.67 and shows 4.5 from 92 reviews, but that star line and the early review text match the smaller 3 x 3 x 4.3 m MissYolo. Do not add the two counts. The attribute says HDPE and gives no gsm figure. There is no parts list, and reviews say tension adjusters are not supplied and that the sail flaps if it is not pulled tight. A bullet claims waterproof cloth and full rain protection, which is seller wording rather than a lab result. At 950 g it is the heavier of the two MissYolo files. The suggested slope is not printed.
Pros
- 3 x 4 x 5 m dark grey sail at about £18.67
- Listed weight 950 g
- UV claim over 95% on the listing
- Lower price than the IOAOI 3 x 4 x 5 m sail
Cons
- The 4.5 from 92 reviews is shared with the smaller MissYolo
- No gsm figure and no parts list
- Tensioners not supplied, according to reviews
- No suggested slope in the file
Best for: A 3 x 4 x 5 m span if you already own tensioners and will treat the star line as one shared pool
Less suitable: A buyer who wants reviews that clearly belong to this size alone

Common questions
Are these 92 reviews only for the 3 x 4 x 5 m size?
The raw file shows 4.5 from 92 reviews and the same early review text as the 3 x 3 x 4.3 m MissYolo ASIN. Do not add the two counts.
Does the box include tensioners?
The listing has no parts list. Reviews say mechanical tension adjusters are not supplied and that the sail flaps if it is not pulled tight.
Can it go near a pool?
The bullets name a pool as a place to use the sail. They do not give a chemical or chlorine rating.
Our view
The pale yellow IOAOI sail is sold as a 3 x 4 x 5 m right-angle triangle at about £29.99, with three ropes and a 4.3-star line from 1,328 reviews. A straight 3-4-5 triangle is a right angle on paper, but a review says the sides curve and did not sit on a 90-degree wall. The cloth name clashes: one bullet says 190 gsm HDPE, the UV bullet says polyester with PU at 160 gsm, and the attribute says HDPE. Reviews say brackets were bought separately. The waterproof claim still depends on a slope so rain does not collect. The 20,000-hour line on the listing is seller copy, not a test in this comparison.
Pros
- 3 x 4 x 5 m size aimed at a right-angle corner
- 4.3 from 1,328 reviews
- Three ropes included
- More cloth than a 3 m equilateral sail
Cons
- Curved sides, so it may not match a square wall corner
- HDPE and polyester both printed
- Brackets are extra, according to reviews
- About £29.99, the highest price in this set
Best for: A patio corner whose spans are close to 3 m, 4 m and 5 m, if you can accept curved edges
Less suitable: A fussy 90-degree wall fit, or a job that needs wall brackets in the box

Common questions
Does this 3 x 4 x 5 m sail include wall fixings?
Included components are three ropes. Reviews say brackets were bought separately. One bullet describes a 1.5 m rope.
Is the cloth HDPE or polyester?
One bullet says 190 gsm HDPE. The UV bullet says polyester with a PU coating at 160 gsm. The material attribute says HDPE.
Will it sit in a square wall corner?
The listing calls it a right-angle sail and also says the large cloth is seamed. A review says the sides curve, so it did not match a 90-degree wall.
Our view
The grey MOXTOYU sail is cut 3 x 3 x 4.3 m in 160 gsm polyester with a PU coating, and the box is one of the fuller kits here. At about £28.99 it includes four 2.4 m ropes, three pad eyes, one carabiner, two tighteners and 16 screws with sleeves. The listing claims 2000 mm water pressure and also says it is not for heavy rain or extreme weather, with the same 20–40 degree tilt. Across 197 reviews it sits at 4.3 stars. The accessory line lists four ropes on a three-corner sail, and the file does not explain the spare. The screws do not name the wall, so brick, timber and a cavity are still your check before you drill.
Pros
- 3 x 3 x 4.3 m polyester sail with a PU coating
- Pad eyes, tighteners, a carabiner and screws in the box
- 4.3 from 197 reviews
- 2000 mm water-pressure claim, with a stated slope
Cons
- Not recommended for heavy rain or extreme weather
- About £28.99, near the top of this set
- Four ropes listed for a three-corner sail
- Screws do not name the wall type
Best for: A longer third span when you do not already own pad eyes or tighteners
Less suitable: Heavy rain, or a tight budget that only needs ropes

Common questions
What fixing hardware is in the box?
The listing lists four 2.4 m ropes, three pad eyes, one carabiner, two awning tighteners, and 16 screws with sleeves. It does not name the wall type.
Is it for heavy rain?
The listing claims 2000 mm water pressure and also says it is not recommended for heavy rain or extreme weather. The suggested slope is 20–40 degrees.
Why are there four ropes on a triangle?
The accessory line lists four ropes. The sail is a three-corner 3 x 3 x 4.3 m triangle. The file does not explain the extra rope.
Our view
Across 1,006 amazon.co.uk reviews, the cream KAHEIGN sail is a 3 x 3 x 3 m equilateral cloth at about £14.99, sold with four 2 m ropes and no hooks. Reviewers treat the D-ring span as larger than the shade you get once the curved edges are tensioned. The listing asks for a 20–40 degree slope so rain does not sit in the middle. One bullet names 180 g/m² HDPE and a 98% UV block, while the material attribute says polyester, so the cloth is not one clear story. The title says waterproof, and a review says it is not. At 4.2 stars this is the largest independent review sample in the set, and you still buy the wall fixings yourself.
Pros
- 3 x 3 x 3 m equilateral sail at about £14.99
- 4.2 from 1,006 reviews on this listing
- Four 2 m ropes in the box
- Listing states a 20–40 degree slope
Cons
- Hooks are not included
- HDPE and polyester both appear on the listing
- A review disputes the waterproof title
- Curved edges make the hung shade smaller than the 3 m span
Best for: A small patio with three similar fixing spans, if you already have hooks
Less suitable: A square wall corner that needs a 3 x 4 x 5 m sail, or a seat you want dry in heavy rain

Common questions
Does the 3 m KAHEIGN sail include hooks?
The box list is the sail and four 2 m ropes. Hooks are not included. The listing says to clip each D-ring to a hook and to tilt the sail 20–40 degrees.
Is the cloth HDPE or polyester?
One bullet says 180 g/m² high-density polyethylene. The material attribute says polyester. The title only says 180 gsm.
Will the hung sail cover a 3 m square?
The size line is 3 x 3 x 3 m with a curved edge. Reviews say the canopy is smaller than the D-ring to D-ring measurement.
Our view
The sandy RICHIE sail measures 3 x 3 x 4.25 m in 300D Oxford with a PU coating, at about £21.09 and 4.2 stars from 76 reviews. That sample is much smaller than the KAHEIGN or IOAOI lines. Ropes are in the box and hooks are not, and the listing asks you to leave 1.5–2 ft between the fixing point and the sail. A review says the point is extended and the edges are not straight, so this is not a clean right angle. The attribute says waterproof while a bullet says a water-resistant coating. At 550 g it is a light cloth for a span of this length.
Pros
- 3 x 3 x 4.25 m sandy 300D Oxford sail
- Ropes included at about £21.09
- 4.2 from 76 reviews
- Stated 1.5–2 ft gap for hardware
Cons
- Hooks sold separately
- Only 76 reviews
- Curved, extended edges rather than a straight right angle
- Waterproof and water-resistant both appear on the listing
Best for: A mid-size span with a longer third side, if you already have hooks
Less suitable: A large independent review sample, or a square wall corner

Common questions
Are the fixing hooks included?
The listing includes ropes and says hardware or hooks are purchased separately. Leave 1.5–2 ft between the fixing point and the sail.
Is it a right-angle sail?
The sides are 3 x 3 x 4.25 m with curved edges. A review says the point is extended and the edges are not straight.
How should it be cleaned?
The listing says mild detergent or water, no stiff brush, no washing machine and no tumble dryer.
Our view
The grey HEYOMART is a 2.5 x 2.5 x 2.5 m equilateral sail in 160 gsm polyester with PU, three 200 cm ropes and three pad eyes, at about £13.99. The title says waterproof. The bullet says water resistant at 400 mm hydrostatic head and that the cloth is not completely waterproof. The suggested slope is 20–40 degrees, and you are told to leave 1.5–2 ft for hardware. It shows 4.1 from 3,648 reviews, and the green ASIN carries the same text, so count that pool once. Shared reviews say the ropes are short. Curved sides can shrink the shade, with a stated tolerance of 4–6 inches a side.
Pros
- 2.5 m equilateral sail with three pad eyes and three 200 cm ropes
- About £13.99
- 160 gsm polyester with a PU coating
- A large shared review pool at 4.1 stars, if you count it once
Cons
- 400 mm head and a line that it is not completely waterproof
- Review text is shared with the green colourway
- Ropes described as short in reviews
- 2.5 m covers a small patch once the tension gap is subtracted
Best for: A small three-point span, such as a balcony or a short patio, where shade matters more than heavy rain
Less suitable: A 3 m patio, or a seat you want dry in a proper shower

Common questions
Is this grey sail waterproof?
The title says waterproof. The bullet says water resistant at 400 mm hydrostatic head and that it is not completely waterproof. The suggested slope is 20–40 degrees.
Do the 3,648 reviews belong only to the grey sail?
The green 2.5 m ASIN carries the same 4.1 from 3,648 and the same review text. Count them once.
How much gap do I leave?
The listing says leave 1.5–2 ft between the fixing point and the sail. Curved sides can shrink the shade, with a stated tolerance of 4–6 inches a side.
Our view
The green HEYOMART matches the grey 2.5 m sail on size, 160 gsm polyester, the 400 mm water line, three 200 cm ropes and three pad eyes, at the same about £13.99. The weight attribute is 520 g, against 510 g on the grey file. The 4.1 from 3,648 reviews is the same text, so this is not a second sample of 3,648 people. The title still says waterproof while the bullet says the cloth is not completely waterproof. Leave 1.5–2 ft between the fixing point and the sail, and expect curved sides to reduce cover by the stated 4–6 inches a side. Choose it for the green cloth, not for a different specification.
Pros
- Green 2.5 m equilateral colourway at about £13.99
- Same 160 gsm polyester and pad-eye kit as the grey listing
- Stated 20–40 degree slope
- A printed 400 mm water line, so the limit is on the page
Cons
- Not a separate review sample from the grey sail
- Not completely waterproof, despite the title
- 200 cm ropes called short in the shared reviews
- Too small for a 3 m fixing span
Best for: The same small span as the grey HEYOMART, when green is the colour you want
Less suitable: A count of 3,648 green-only reviews, or a patio that needs a 3 m sail

Common questions
How is the green sail different from the grey one?
The size, cloth, 400 mm line and rope list match. This ASIN is green and the weight attribute is 520 g, against 510 g on the grey file. The review text is the same.
Will the ropes reach?
The box includes three ropes of 200 cm. Shared reviews say the ropes are short. Leave 1.5–2 ft for hardware.
Is it completely waterproof?
No. The bullet says 400 mm hydrostatic head and that the cloth is not completely waterproof, even though the title says waterproof.
Our view
The grey Sowoxdme sail is listed as 3 x 3 x 4 m in 160 gsm polyester with PU, three 2.5 m ropes and a 20–40 degree slope, at about £25.99. It scores 4.0 from 178 reviews. One review says the centre stays baggy even when the edges are pulled hard, and another says a sail ripped within a week. Hooks are still extra. A 40 x 40 cm dimension attribute contradicts the 3 m size line, and a bullet also mentions 3 m, 4 m and 5 m as optional lengths, so check the size on the listing before you order. The waterproof claim has no millimetre figure in the file.
Pros
- 3 x 3 x 4 m polyester sail
- Three 2.5 m ropes
- 4.0 from 178 reviews
- Stated 20–40 degree slope
Cons
- Centre can stay baggy when the edges are tight
- A review reports a rip within a week
- Fixings are not in the box
- The 40 x 40 cm dimension line clashes with the size
Best for: A 3 m by 4 m third side when you already own wall fixings and will check the size option
Less suitable: A sail you need drum-tight in the middle, or a listing with a clean size attribute

Common questions
Which size is this ASIN?
The size line is 3 x 3 x 4 m. A bullet also mentions 3 m, 4 m and 5 m as optional lengths. The 40 x 40 cm dimension attribute contradicts the size line.
Are hooks in the box?
The box list is one canopy and three ropes of 2.5 m. A review says you still need fixings. The suggested slope is 20–40 degrees.
Does the middle pull tight?
One review says the centre stays baggy even when the edges are pulled hard. Another says a sail ripped within a week.
Our view
The grey DAJAVE sail is a 3 x 3 x 3 m 420D Oxford cloth with PU, at about £19.99, and the raw file has no Customer Reviews line. The kit is fuller than a ropes-only box: three 2 m ropes, two carabiners, two lag screws, four pad eyes, 16 metal screws and 16 expansion screws. The listing says light to moderate rain is the use, and that continuous heavy rain may leak slightly, with a 20–40 degree angle. It claims 95% UV block, which stays a seller figure. A 10 x 10 mm dimension attribute contradicts the 3 m size and is not the sail. At 1.33 kg it is one of the heavier cloths here, with no star rating to set beside the kit.
Pros
- 3 m equilateral 420D Oxford sail
- Fixing kit with pad eyes, screws and carabiners
- Light-to-moderate rain limit written on the listing
- Stated 20–40 degree slope
Cons
- No Customer Reviews line in the raw file
- Not for continuous heavy rain
- A 10 x 10 mm dimension line clashes with the 3 m size
- About £19.99 with no star sample to compare
Best for: A 3 m equilateral span when you want screws and pad eyes in the box and can accept an unrated listing

Common questions
Does DAJAVE include fixings?
Yes. The list is one 3 x 3 x 3 m sail, three 2 m ropes, two carabiners, two lag screws, four pad eyes, 16 metal screws and 16 expansion screws.
How waterproof is it?
The listing says it can take light to moderate rain and is not recommended in heavy rain. Continuous heavy rain may leak slightly. The suggested angle is 20–40 degrees.
Why is there no star rating?
The raw file has no Customer Reviews line and no review text. The 10 x 10 mm dimension line contradicts the 3 m size and is not the sail size.
Our view
The grey YOUNTHYE sail is another 3 x 3 x 3 m 420D Oxford with PU, at about £23.99, and it also has no Customer Reviews line. The kit lists four 2 m ropes, two tighteners, two carabiners, four pad eyes and 16 expansion tubes with screws. The wall or post those screws suit is not named. The title says waterproof without the heavy-rain limit that DAJAVE prints. The item-weight attribute says 10 g, which is not a credible mass for this sail, so do not use it. A 95% UV line is seller copy. You pay more than the DAJAVE kit for tighteners in the box and a thinner set of warnings, with no reviews to read.
Pros
- 3 m equilateral sail with tighteners in the box
- Four 2 m ropes, pad eyes, carabiners and expansion screws
- 95% UV claim printed on the listing
- The 3 x 3 m dimension attribute matches the size line
Cons
- No Customer Reviews line
- About £23.99, above the DAJAVE kit
- The 10 g item weight is not credible
- Waterproof claim with no heavy-rain sentence in the file
Best for: A 3 m span when you want tighteners included and will judge the cloth yourself
Less suitable: A decision based on review volume, or any use of the 10 g weight figure

Common questions
What is in the fixing kit?

How heavy is it?

How we compared
Scores compare the eleven amazon.co.uk listings kept in this set. Prices, stars and review counts are the figures in the saved listing files, not a live re-check. There is no laboratory test. A seller UV percentage is not a UPF result. Each score is out of 100. Shared review text, a missing Customer Reviews line, and a material or size clash reduce the score. The weights below sum to 100.

Triangle shade sail buying guide
Measure three fixing points before you read a waterproof title. Equal sides suit a simple span. A 3 × 4 × 5 m sail is sold for a corner. A UV percentage on the cloth is the seller’s claim, and what those lines do and do not mean is in [what UV claims on shade actually mean](/hub/sun-shades/blog/what-uv-claims-on-shade-actually-mean).
What is a triangle shade sail?
A triangle shade sail is a three-corner outdoor cloth with a ring at each corner, tensioned between walls, posts or a pergola. In this set the ready-made choice is an equilateral sail, 2.5 m or 3 m a side, or a longer triangle such as 3 × 4 × 5 m, 3 × 3 × 4.3 m, 3 × 3 × 4.25 m or 3 × 3 × 4 m. Made-to-measure sails sit outside these eleven amazon.co.uk listings. Measure three fixing points and subtract a tension gap. Several listings say leave about 1.5–2 ft, roughly 45–60 cm.
Best for
- Shade on a patio or pergola for the hot weeks, if you will take the sail down
- A corner span close to 3 m, 4 m and 5 m, if the curved edges still fit
Not ideal for
- A seat you need dry in heavy rain
- Concrete posts, a cavity wall, a listed building, a flat, or several sails over a walkway
Mistakes to avoid
- 1
Treating the side lengths as the shaded patch
Corner-to-corner size is not the shade you get. Curved edges shrink the cover, and several listings say leave about 1.5–2 ft, roughly 45–60 cm, between the fixing point and the sail.
- 2
Hanging the sail flat
Rain sits in the middle of a flat sail. Seller guides use 20–30 degrees, 20–40 degrees, or about 30 cm of fall per metre, with one corner lower.
- 3
Trusting waterproof after a 400 mm line
HEYOMART’s title says waterproof and the bullet says 400 mm head and not completely waterproof. DAJAVE and MOXTOYU both keep a heavy-rain limit on the page. A waterproof title is not a storm-proof roof.
What to weigh up
Geometry, gap and the shaded area
HighStart with three fixing points, then the shape. Equal sides suit a simple span: 3 m on KAHEIGN, DAJAVE and YOUNTHYE, and 2.5 m on both HEYOMART colourways. A 3 × 4 × 5 m sail is the corner shape, on IOAOI and the larger MissYolo. RICHIE, MOXTOYU, Sowoxdme and the smaller MissYolo use a longer third side between those two. An equilateral 3 m sail is about 3.9 square metres of cloth. A straight 3-4-5 triangle is 6 square metres.
Water line, box and UV claims
HighRead the sentence under the waterproof title. HEYOMART states 400 mm and says the cloth is not completely waterproof. DAJAVE limits use to light or moderate rain. MOXTOYU claims 2000 mm and still says it is not for heavy rain. Hang one corner lower: 20–30 degrees, 20–40 degrees, or about 30 cm of fall per metre. YOUNTHYE, DAJAVE and MOXTOYU put fixings in the box. KAHEIGN, RICHIE, IOAOI and Sowoxdme are sail and ropes. MissYolo reviews ask for tensioners that are not supplied.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
House-wall corner
You want a 3 × 4 × 5 m sail between a house wall and a side fixing. This is the right-angle listing with 4.3 from 1,328 reviews. Curved edges may not sit on a square corner, and brackets are extra.
Light rain, limit on the page
You need the heavy-rain sentence in writing. This 3 m kit says light to moderate rain, and that continuous heavy rain may leak slightly. There is no Customer Reviews line.
Common questions about triangle shade sails
Which triangle shade sail is the top pick in this set?
In this set the top pick is the KAHEIGN cream sail, 3 × 3 × 3 m, at about £14.99. It is 4.2 from 1,006 amazon.co.uk reviews on that listing, the largest sample here that is not shared with another ASIN, and the highest score at 80. The box is the sail and four 2 m ropes. Hooks are extra. The listing names both HDPE and polyester, and a review disputes the waterproof title. It suits three similar fixing spans if you already have hooks.
Which listing is the best value?
The best value is the MissYolo 3 × 3 × 4.3 m dark grey sail at about £11.90, the lowest shelf price in this set. The 750 g weight separates it from the 3 × 4 × 5 m MissYolo at 950 g. Both listings show 4.5 from 92 reviews and the same early review text, so that is one pool. The attribute says HDPE and prints no gsm figure. There is no parts list, and the shared reviews say tensioners are not supplied.
How much does a triangle shade sail cost on amazon.co.uk?
Loaded shelf prices for these eleven amazon.co.uk listings run from about £11.90 to £29.99. Entry, about £12–£15, is the smaller MissYolo, both HEYOMART 2.5 m colourways and the KAHEIGN 3 m sail. Mid, about £19–£24, is the larger MissYolo, DAJAVE, RICHIE and YOUNTHYE. The upper end of this ready-made set, about £26–£30, is Sowoxdme, MOXTOYU and IOAOI. Made-to-measure sails sit outside the set. These are the saved listing prices, not a live re-check.
Should I buy an equilateral sail or a longer triangle?
Equal sides suit a simple three-point span. A 3 m equilateral sail is about 3.9 square metres of cloth. A 3 × 4 × 5 m sail is a right-angled triangle sold for corners, and a straight 3-4-5 triangle is 6 square metres. Curved edges make the hung shade smaller than the corner-to-corner size, and several listings say leave about 1.5–2 ft, roughly 45–60 cm. A review of the IOAOI sail says the sides curve and did not sit on a 90-degree wall.
Does a waterproof title mean the sail sheds heavy rain?
A waterproof title is the seller’s claim, not a storm-proof roof. HEYOMART’s title says waterproof and the bullet says water resistant at 400 mm head and not completely waterproof. DAJAVE limits use to light or moderate rain and says continuous heavy rain may leak slightly. MOXTOYU claims 2000 mm and still says it is not for heavy rain. Hang one corner lower. Seller guides use 20–30 degrees, 20–40 degrees, or about 30 cm of fall per metre.
What does a UV percentage on a shade sail mean?
A percentage on the listing is the seller’s UV claim, not a UPF test from this desk. GOV.UK notes that BS EN 13758-2 allows a solar UV-protective clothing label only at UPF 40 or above. These sails do not show a UPF. The NHS still wants shade between 11am and 3pm from March to October, clothing, and SPF 30 sunscreen with at least 4-star UVA protection. Shade from a sail does not replace sunscreen.
When is a four-corner sail the better fit?
This page is three-corner sails only. A rectangle or square cloth with four fixing points is a different product. If the patio, pergola or balcony needs four anchors rather than three, compare sun sails. Take the sail down for the season if you only need shade in the hot weeks. Call a builder and the planning authority for concrete posts, a cavity wall, a listed building, a flat, or several sails over a walkway.
Our verdict
In this set the top pick is the KAHEIGN 3 × 3 × 3 m cream sail: about £14.99, 4.2 from 1,006 reviews on that listing, and the highest score at 80. Hooks are not in the box, the listing names both HDPE and polyester, and a review disputes the waterproof title. The best value is the MissYolo 3 × 3 × 4.3 m sail at about £11.90, the lowest shelf price here, for a stated longer third side. Its 4.5 from 92 reviews is the same text as the larger MissYolo, there is no parts list, and the shared reviews say tensioners are not supplied. IOAOI scores 76 at about £29.99 with 4.3 from 1,328 reviews and is not the best value: it is the top of this price band, and the cloth name clashes.
