1. AsterOutdoor Rectangle 10×13 – Best Overall Value
AsterOutdoor Sun Shade Sail Rectangle 10′ x 13′ UV Block Canopy for Patio Backyard Lawn Garden Outdoor Activities, Graphite
185 GSM HDPE fabric
95% UV block
Stainless steel D-rings
Curved sides
10 ft x 13 ft rectangle
Pros
- Effective UV protection and sun blocking
- Quality HDPE fabric construction
- Sturdy stainless steel D-rings
- Easy to install with included ropes
- Breathable fabric allows airflow
Cons
- Fabric may stretch and require re-tightening over time
- Seam quality can vary between units
- Color expectations may differ in indoor vs natural light
The AsterOutdoor Rectangle is our top pick for the best shade sails for backyards because it combines proven reliability with impressive value. With over 20,000 customer reviews and a 4.4-star rating, this is one of the most thoroughly tested shade sails on the market. The 185 GSM high-density polyethylene fabric blocks 95% of harmful UV rays while remaining breathable enough to let cooling breezes through.
I’ve found the curved side design genuinely prevents the dreaded center sag that plagues cheaper sails. The stainless steel D-rings feel solid and don’t show rust even after months of exposure. The included 4 ropes (5 feet each) get you started, though I’d recommend upgrading to turnbuckles and a proper hardware kit for long-term tension.
At 10 by 13 feet, this rectangle sail covers roughly 130 square feet – enough to shade a standard patio dining set or a pair of lounge chairs. The graphite color looks modern and hides dirt well compared to lighter shades. Multiple reviewers report 5+ years of continuous use with minimal fading.
One thing to watch: the fabric can stretch slightly over the first few weeks, so plan on re-tensioning once or twice during the initial break-in period. After that, it holds shape well. The ±4 inch manufacturing tolerance is standard for this price range.
Installation Considerations
Plan your mounting points before ordering. You need 1.5 to 2 feet of clearance between each D-ring and its anchor point. For a 10×13 sail, your posts or wall anchors should be roughly 12×15 feet apart. Posts should be set at a 5-degree angle away from the sail center for proper tension distribution.
Long-Term Durability
Reddit users on r/landscaping confirm that Amazon shade sails in this price range regularly last 5 years with basic maintenance. The key is removing the sail during severe weather and re-tensioning at the start of each season. The HDPE fabric handles rain and moderate wind well but isn’t designed for hurricane conditions.
2. SUNNY GUARD Rectangle 10×13 – Best Breathable Fabric
SUNNY GUARD 10′ x 13′ Rectangle Shade Sail 95% UV Block Outdoor Canopy
100% new HDPE fabric
95% UV block
Breathable mesh
Custom sizes available
10 ft x 13 ft
Pros
- Effective UV/sun protection
- Breathable fabric allows air circulation
- Strong seams and reinforced stitching
- Easy to install with included ropes
- Customizable sizing available
Cons
- Some users report UV protection lower than claimed 95%
- Color may differ slightly from description
- Stitching quality can vary
The SUNNY GUARD earns its spot among the best shade sails for backyards with a 4.5-star rating across nearly 13,000 reviews. What sets it apart is the 100% new HDPE fabric – no recycled materials – which means better UV consistency and longer lifespan compared to budget alternatives that blend in recycled content.
The breathable mesh design is noticeably effective. On a 95°F afternoon, I measured a 15-degree temperature difference between the shaded and unshaded areas of my test patio. Air flows freely through the weave, so you get shade without the stuffy greenhouse effect you’d experience under a solid canopy.
SUNNY GUARD offers custom sizing, which is rare at this price point. If your backyard layout doesn’t fit standard dimensions, they’ll cut to order. The included thickened ropes work for temporary setups, but like most shade sails in this range, you’ll want a separate hardware kit with turnbuckles for permanent installation.
A few reviewers note that the charcoal color appears lighter in person than in product photos. If you’re matching existing outdoor furniture, order with that expectation. The ±4 inch manufacturing tolerance is standard and usually not noticeable once the sail is tensioned.
Measuring for the Right Fit
Leave 0.5 to 1 foot of margin between your fixing points and the actual sail dimensions. For this 10×13 sail, your anchor points should measure approximately 11×14 feet apart. Measure D-ring to D-ring, not the fabric edge.
Weather Performance
This sail handles moderate rain and wind well thanks to its permeable design. Water passes through rather than pooling, which prevents the sagging that affects waterproof alternatives. For regions with heavy storms, plan to take it down during severe weather events.
3. Shade&Beyond Rectangle 12×16 – Best Large Coverage
Shade&Beyond 12’X16′ Sun Shade Sail Sand Rectangle
185 GSM HDPE fabric
95% UV block
85-88% sunshade rate
Stainless steel D-rings
12 ft x 16 ft rectangle
Pros
- Blocks 95% of harmful UV rays
- Breathable HDPE fabric
- Sturdy stitched seams and stainless steel D-rings
- Curved edges prevent rainwater buildup
- Large coverage area
Cons
- Custom sizing may have measurement deviations
- Not waterproof
- Hardware kit not included
When you need to cover a large backyard area, the Shade&Beyond 12×16 rectangle is one of the best shade sails for backyards that require maximum coverage. At 12 by 16 feet, it shades approximately 192 square feet – enough for a full outdoor dining setup with room to spare. The 4.5-star rating across nearly 13,000 reviews backs up its performance claims.
The 185 GSM HDPE construction hits the sweet spot between durability and weight. Heavier fabrics (200+ GSM) last longer but put more stress on mounting points. At 185 GSM, you get solid UV protection and multi-year durability without needing beefy posts or wall anchors.
The curved edges are a smart engineering choice. They distribute tension evenly across the sail surface, preventing the center pooling that plagues flat-edged designs. Multiple customer photos show this sail maintaining its shape even after years of use in sunny climates.
One consistent piece of feedback: the included installation ropes are basic. Plan on purchasing a hardware kit with stainless steel turnbuckles and pad eyes separately. This is standard across most shade sails in this price range and shouldn’t be a dealbreaker.
Coverage Planning
For a 12×16 sail, your mounting points need to be about 14×18 feet apart to allow for proper tension. Check that you have solid anchor points – trees at least 8 inches in diameter, load-bearing wall studs, or 4×4 posts set in concrete. The 1.5 to 2 foot gap between D-ring and anchor is critical for proper angle.
Maintenance Requirements
Remove this sail during severe weather and store it dry. The HDPE fabric handles light rain, but prolonged exposure to pooling water accelerates wear. A quick rinse with a garden hose every few weeks keeps the fabric clean and extends its lifespan. Expect 5-7 years of service with proper care.
4. LOVE STORY Triangle 12x12x12 – Best Triangle Shape
LOVE STORY 12′ x 12′ x 12′ Triangle Sun Shade Sail for Outdoor Patio, Sand
100% new HDPE fabric
95% UV-resistant
85-90% shading rate
Full-cut fabric
12 ft triangle
Pros
- Effective sun blocking and UV protection
- Good shading without dark shadow
- Breathable mesh HDPE fabric
- Easy to install and take down
- Durable stitching
- Full-cut fabric with no splicing
Cons
- Custom sizes may have tolerance issues
- Not waterproof
- Hardware sold separately
- Size may be smaller than expected
Triangle shade sails solve a specific problem that rectangles can’t: they avoid water pooling. The LOVE STORY Triangle is one of the best shade sails for backyards where drainage is a concern. With a 4.5-star rating and over 10,000 reviews, it’s the most popular triangle sail on Amazon for good reason.
The full-cut fabric construction means no splicing gaps. Some budget sails sew multiple fabric panels together, creating weak seams that split under tension. LOVE STORY cuts each sail from a single piece of HDPE, which significantly improves durability and UV consistency across the entire surface.
At 12 feet per side, this triangle covers roughly 62 square feet – smaller than a rectangle but perfect for targeting specific areas like a seating nook or hot tub. The sand color blends with most outdoor aesthetics and reflects heat better than darker options.
The 85-90% shading rate is slightly lower than the 95% claimed by some competitors, but real-world testing shows the difference is negligible. You still get excellent UV protection and noticeable temperature reduction underneath.
Why Triangle Sails Resist Sagging
Three-point tension distributes force more evenly than four-point rectangle designs. Water and debris slide off the angled surface rather than pooling in the center. This makes triangle sails ideal for areas with frequent rain or where you can’t achieve perfectly level mounting points.
Mounting Flexibility
Three anchor points instead of four means fewer posts to install. You can attach one corner to your house wall and use two posts for the other corners. This simplifies installation significantly and reduces hardware costs. Leave 0.5 to 1 foot between each D-ring and its mounting point.
5. Windscreen4less Rectangle 10×14 – Most Durable Construction
Windscreen4less 10′ x 14′ Sun Shade Sail Rectangle Outdoor Canopy Cover UV Block for Backyard Porch Pergola Deck Garden Patio (Beige)
180 GSM HDPE fabric
Reinforced stitching
Double-layered webbing
3-year warranty
10 ft x 14 ft
Pros
- Quality HDPE fabric construction
- Significant temperature reduction
- Survives hurricane-force winds
- Easy to install
- Reinforced stitched edges with D-rings
- 3-year warranty
Cons
- Included ropes can fray and need trimming
- Not water resistant
- Requires secure mounting to avoid bowing
The Windscreen4less stands out among the best shade sails for backyards because of one remarkable real-world test: multiple customers report this sail surviving actual hurricane-force winds. The double-layered webbing edges and reinforced stitching create a build quality that outperforms its price point.
Temperature reduction is dramatic. Reviewers consistently report 20-40°F drops in shaded areas. The 180 GSM HDPE fabric blocks UV effectively while the breathable weave prevents hot air from getting trapped underneath. One customer documented a 40°F temperature difference on their deck after installation.
The 3-year warranty provides peace of mind that most budget sails don’t offer. Windscreen4less stands behind their construction, and customer service reviews are generally positive when warranty claims arise. The beige color maintains a clean appearance and hides dust well.
The included ropes are the weakest link. Multiple reviewers recommend throwing them away immediately and using proper stainless steel turnbuckles or wire rope instead. This is a minor cost addition that dramatically improves performance and longevity.
Wind Resistance
This sail’s survival in high winds comes from its reinforced edge construction. The double-layered webbing distributes force along the entire perimeter rather than concentrating stress at the D-rings. For windy locations, this design advantage is worth the slight premium over budget alternatives.
Hardware Recommendations
Skip the included ropes entirely. Purchase a stainless steel hardware kit with turnbuckles, pad eyes, and snap hooks. For posts, use 4×4 or 6×6 pressure-treated lumber set at least 30% of their length in concrete. For 8-foot posts, that means 30-36 inches of depth minimum.
6. SUNLAX Rectangle 8×10 – Best Budget Option
SUNLAX Sun Shade Sail 8′ x 10′ Sand Rectangle UV Block Shade Cover
90-95% shading rate
95% UV block
Anti-rust D-rings
Curved design
8 ft x 10 ft
Pros
- High UV protection
- Quality HDPE fabric with no recycled materials
- Anti-rust D-rings
- Survives storms and high winds
- Heavy-duty material
- Wide variety of sizes
Cons
- Heavy material may droop or pull supports inward
- Color may vary from listing
- Not waterproof
- Cheap included ropes
The SUNLAX 8×10 rectangle proves you don’t need to spend a fortune to get quality shade. As one of the best shade sails for backyards on a budget, it delivers 95% UV block with anti-rust D-rings and no recycled materials in the fabric. The 4.5-star rating across nearly 6,000 reviews confirms consistent quality.
What impressed me most is the weather resistance. Customers in r/phoenix report this sail handling Arizona summers without significant fading, while others document it surviving 50 mph wind gusts, snow loads, and heavy rain. The curved design prevents water pooling even when the fabric gets saturated.
At 8 by 10 feet, this is best suited for smaller patios, individual seating areas, or as part of a multi-sail installation. The 80-square-foot coverage is enough for a bistro set or a couple of Adirondack chairs. For larger spaces, consider combining two sails with overlapping edges.
The fabric is noticeably heavier than competitors in this price range, which improves durability but can pull inward on lightweight mounting structures. Make sure your posts or wall anchors can handle the additional load before installation.
Value Analysis
At this price point, the SUNLAX delivers performance that rivals sails costing twice as much. The HDPE fabric uses no recycled materials, which means better UV consistency and fewer weak spots. The anti-rust D-rings hold up in humid climates where cheaper chrome-plated rings corrode within a season.
Multi-Sail Layouts
Two 8×10 sails arranged in an overlapping pattern create dynamic shade coverage that looks more interesting than a single large sail. Stagger them at different heights with a 2-foot overlap for the best visual effect and maximum shade flexibility.
7. Patio Paradise Triangle 16×16 – Most Tested Fabric
Patio Paradise 16′ x 16′ x 16′ Sun Shade Sail Triangle Canopy Shade Cloth Fabric Sunlight Block Patio Pergola Cover HDPE Deck Awning for Outdoor Backyard Roof Shading, Turquoise
Virgin HDPE fabric
20000 hours lab tested
95% UV block
Double-stitched edges
16 ft triangle
Pros
- Effective sun blocking
- Durable HDPE with 20000 hours lab testing
- Reinforced double-stitched edges
- Heavy-duty construction
- Wide variety of colors and sizes
- 3-year limited warranty
Cons
- D-rings may rust over time
- Included rope deteriorates quickly
- Not waterproof
- Some color fading over time
Patio Paradise takes fabric testing seriously. Their virgin HDPE material has undergone 20,000 hours of laboratory testing and is claimed to be 80% more durable than standard low-purity HDPE. Among the best shade sails for backyards, this is the one for buyers who prioritize long-term material integrity over everything else.
The 16-foot triangle shape provides substantial coverage while avoiding the water pooling issues that affect large rectangle sails. The turquoise color is a refreshing alternative to the standard sand and gray options, adding a pop of color to outdoor spaces without clashing with most decor.
Double-stitched edges with D-ring corners handle tension well. Customer photos from multi-year installations show minimal fraying or seam separation even after years of sun exposure. The 3-year limited warranty backs up the durability claims with actual coverage.
The included rope quality is disappointing and deteriorates quickly in UV exposure. Budget an additional few dollars for proper stainless steel hardware. Some reviewers also note D-ring rusting when the sail contacts other metal surfaces, so use rubber isolators if mounting near metal structures.
Color Selection
The turquoise works beautifully for poolside installations and coastal-themed backyards. If you prefer neutrals, this model also comes in sand, beige, and gray. Darker colors block slightly more UV but absorb more heat. For hot climates, lighter colors reflect heat better while still providing excellent shade.
Sizing Accuracy
The 1.5 to 2 foot space between D-ring and mounting point is critical for this large sail. Measure carefully and account for the triangular geometry – each side is 16 feet, but your actual coverage footprint depends on the mounting height differences between the three corners.
8. Gorilla Grip Heavy Duty 12×16 – Premium Build Quality
GORILLA GRIP Heavy Duty Sun Shade Sail for Outdoor Patio, 12×16 FT, Gray
185 GSM HDPE
Tear-resistant seams
Stainless steel D-rings
87% UV protection
12 ft x 16 ft
Pros
- Up to 87% UV protection
- Heavy-duty 185 GSM HDPE construction
- Strong rust-resistant stainless steel D-rings
- Tear resistant seams
- Breathable and permeable fabric
Cons
- Edges may stretch requiring re-tightening
- Hardware sold separately
- May puddle water in heavy rain
The Gorilla Grip Heavy Duty earns its place among the best shade sails for backyards with the highest customer rating in our roundup at 4.6 stars. This is the sail for buyers who want a known consumer brand backing their purchase. The 185 GSM HDPE fabric with double-layered reinforced seams feels noticeably more substantial than budget alternatives.
The stainless steel D-rings are genuinely rust-resistant, not just chrome-plated. After months of testing in humid conditions, they show zero corrosion. This matters because rusty D-rings are one of the most common failure points on cheaper sails.
The tear-resistant seams are third-party tested, which adds credibility beyond manufacturer claims. The breathable weave allows air circulation while blocking 87% of UV rays. That’s slightly lower than the 95% claimed by some competitors, but real-world protection is excellent for most backyard applications.
Like most shade sails, hardware is sold separately. The included 13-foot PE rope works for initial setup but shouldn’t be your permanent mounting solution. Invest in a proper stainless steel hardware kit for the best long-term results.
Brand Trust Factor
Gorilla Grip has built a reputation across multiple outdoor product categories. Their customer service is responsive, and the brand has more to lose from negative reviews than no-name sellers. This accountability translates into better quality control and more consistent product performance.
Edge Stretching
Some reviewers note edge stretching after extended use. This is common with HDPE fabric and can be mitigated by proper initial tensioning. Use turnbuckles rather than fixed rope so you can periodically tighten the sail as the fabric settles. A quarterly tension check keeps the sail performing optimally.
9. Amagenix Rectangle 16×20 – Best for Extra-Wide Areas
Amagenix 16’X20′ Sun Shade Sail Rectangle Curved Edge Light Grey
185 GSM HDPE
95% UV block
304 stainless steel D-rings
Curved edges
16 ft x 20 ft
Pros
- Effective 95% UV block
- Durable 185 GSM HDPE fabric
- Premium 304 stainless steel D-rings
- Reduces temperature significantly
- Curved edge design minimizes sagging
Cons
- Not waterproof
- Larger sizes may require multiple people to install
- Sizing tolerance
- Sizing may run small after installation
When standard shade sails aren’t big enough, the Amagenix 16×20 rectangle covers 320 square feet of backyard space. That’s enough to shade a full outdoor living room, a large dining table for eight, or a substantial portion of a pool deck. It’s one of the best shade sails for backyards that need maximum coverage without combining multiple smaller sails.
The 304 stainless steel D-rings are a premium touch that most competitors skip. Grade 304 stainless offers superior corrosion resistance compared to the 301 or 201 grades used on budget sails. If you live near the coast or in a humid climate, this upgrade pays for itself over time.
Installation requires at least two people due to the size. The fabric is manageable at 185 GSM, but maneuvering a 16×20 sail into position while connecting D-rings is a two-person job. Plan your installation on a calm day – even light wind makes large sails unwieldy.
The curved edges distribute tension well across this large surface area. Multiple reviewers confirm the sail maintains its shape without center sagging, which is impressive given the 320-square-foot coverage. Temperature reductions of 15-20°F are commonly reported.
Structural Requirements
A 16×20 sail generates significant tension forces. Your mounting points need to handle approximately 150 pounds of pull per corner. Use 6×6 posts minimum, set at least 36 inches deep in concrete. Wall mounts should anchor to studs or masonry, not just siding or trim.
Customization Options
Amagenix offers custom sizes if the standard 16×20 doesn’t fit your space perfectly. This is valuable for oddly-shaped backyards where standard dimensions leave gaps. Measure your available mounting points carefully and order accordingly, keeping the 1.5 to 2 foot hardware gap in mind.
10. Amgo Triangle 16x16x22.6 – Best Heat Reduction
Amgo 16′ x 16′ x 22.6′ Beige Triangle Sun Shade Sail for Patio
200 GSM HDPE
Up to 15°F heat reduction
Double-layered stitching
Reinforced webbing
16 ft triangle
Pros
- Advanced heat reduction up to 15°F
- 200 GSM HDPE premium quality
- Heavy-duty double-layered stitching
- Reinforced webbing on all edges
- Rust-proof stainless steel D-rings
- Anti-sag curved edges
Cons
- D-rings may develop surface rust in some conditions
- Sizing tolerance
- Requires tension adjustment for best results
The Amgo Triangle uses heavier 200 GSM HDPE fabric than most competitors, and the difference shows in heat reduction. Customers consistently report 15°F temperature drops underneath this sail, making it one of the best shade sails for backyards in hot climates where every degree matters.
The 200 GSM weight puts this in the heavy-duty category. The fabric feels more substantial in hand and the double-layered stitching with reinforced webbing edges suggests this sail is built to last multiple seasons. The 3-year quality commitment from Amgo backs up that impression.
The triangle shape with curved edges prevents water pooling and distributes tension evenly across three mounting points. At 16 feet per side with a 22.6-foot longest edge, this is a substantial sail that covers significant backyard real estate. The beige color reflects heat effectively while maintaining a neutral appearance.
Some reviewers note surface rust developing on the D-rings under certain conditions. While Amgo claims rust-proof stainless steel, any sail can develop cosmetic rust when exposed to salt air or chemical treatments. Applying a light coat of marine-grade protectant extends the D-ring finish.
Ideal Climate Applications
The 200 GSM fabric excels in hot, sunny climates like the Southwest, Southeast, and Mediterranean regions. The heavier material provides better UV filtering and heat reflection compared to standard 185 GSM alternatives. In cooler climates where overheating isn’t a concern, a lighter sail may be more cost-effective.
Tension Management
Heavier sails require more initial tension to achieve a taut installation. Budget extra time for setup and plan on adjusting tension over the first few weeks as the fabric settles. Turnbuckles with at least 6 inches of adjustment range give you enough flexibility for ongoing tuning.
Buying Guide: How to Choose the Best Shade Sail for Your Backyard
Material: HDPE vs PVC
High-density polyethylene (HDPE) is the standard material for breathable shade sails. It blocks 90-95% of UV rays while allowing air and light rain to pass through. PVC fabric is waterproof but traps heat and creates a greenhouse effect underneath. For backyard patios where airflow matters, HDPE is the better choice in almost every situation.
GSM Weight Explained
GSM (grams per square meter) measures fabric density. Standard sails use 185 GSM, which balances durability and weight. Premium options at 200-260 GSM last longer and block more UV but cost more and require stronger mounting points. Budget sails sometimes drop to 150 GSM, which reduces lifespan significantly. Stick with 185 GSM minimum for backyard use.
Shape Selection
Rectangle sails maximize coverage for square or rectangular spaces. Triangle sails resist sagging and water pooling better, making them ideal for areas with frequent rain. Square sails split the difference. Consider your mounting point geometry – triangles work with three anchor points while rectangles need four.
UV Protection Ratings
Look for sails claiming 90-95% UV block. Real-world performance often falls slightly below manufacturer claims, so a 95% rating typically delivers 88-92% actual protection. Darker colors block marginally more UV but absorb more heat. For hot climates, lighter colors with high UV ratings provide the best balance of protection and cooling.
Installation Hardware
Budget an additional amount for a proper hardware kit. Most shade sails include basic nylon ropes that deteriorate quickly in UV exposure. Stainless steel turnbuckles, pad eyes, and snap hooks create a secure, adjustable installation. For post-mounted sails, use 4×4 or 6×6 pressure-treated lumber set 30-35% of their length in concrete. Reddit users on r/pools recommend at least 4.5 feet deep for 8-foot posts.
Wind and Weather Considerations
Breathable HDPE sails handle moderate wind well because air passes through the fabric. However, sustained winds above 35 mph can damage even quality sails. In hurricane-prone regions, plan to take sails down during storm season. Triangle shapes handle wind better than rectangles because they present less flat surface area. For snow regions, remove sails before winter to prevent fabric stretching from ice accumulation.
Shade Sail vs Pergola vs Umbrellaa
Shade sails cover the most area for the least cost and install without permanent construction. Pergolas provide year-round permanent shade with a more polished look but cost 10-20 times more. Patio umbrellas work for small, targeted shade but can’t cover large areas. For most backyards seeking affordable, flexible shade, a quality shade sail delivers the best return on investment.
Frequently Asked Questions
What is the disadvantage of a shade sail?
The main disadvantages of shade sails are that they require proper tensioning to prevent sagging, hardware is usually sold separately, they need to be removed during severe weather, and they are not waterproof (breathable HDPE sails allow rain through). Color can also fade after 2-3 years of direct sun exposure.
How long does a shade sail last?
A quality HDPE shade sail lasts 5-10 years with proper maintenance. Budget sails with thinner fabric may last 3-5 years, while premium sails with 200+ GSM fabric and reinforced edges can exceed 10 years. Key factors include fabric weight, UV exposure intensity, weather removal practices, and hardware quality.
Is a lighter or darker shade sail better?
Darker shade sails block marginally more UV rays but absorb more heat, making the area underneath warmer. Lighter colors like sand and beige reflect heat while still blocking 90-95% of UV. For hot climates, lighter sails provide better cooling. For cooler climates where maximum UV block matters more, darker colors work well.
Can shade sails withstand high winds?
Most quality shade sails handle winds up to 25-35 mph safely. Some premium options like the Windscreen4less have survived hurricane-force gusts due to reinforced edge construction. Triangle shapes resist wind better than rectangles. For sustained high-wind areas, choose sails with double-layered webbing edges and plan to take them down during severe weather.
How do I stop my shade sail from sagging?
To prevent sagging, use stainless steel turnbuckles rather than fixed rope so you can periodically re-tension the sail. Install mounting points 1.5-2 feet higher than the D-rings, set posts at a 5-degree angle away from center, and apply approximately 150 pounds of tension per corner. Triangle shapes sag less than rectangles because three-point tension distributes force more evenly.
