Cool It, Then Cover It: Best Grill Covers for Gas Grills, Kettles and Griddles

As an Amazon Associate, we earn from qualifying purchases. This doesn’t change our recommendations or the price you pay.

The best grill cover is the one that actually fits your grill. A cover that’s too small won’t reach the legs and rides up in the wind; one that’s far too big flaps, pools rain and wears through where it rubs. So the tape measure comes before the fabric claims.

We compared seven covers sold by Amazon.com or by the brand itself: model-specific covers from Weber and Blackstone, Char-Broil’s sized-by-burner covers, and universal covers from Unicook and SunPatio. We quote each listing’s fabric, waterproof and UV wording as the brand states it, note which ones mention straps or vents, and flag listings with empty warranty fields or size and weight figures that don’t add up.

One rule comes before any of that: never put a cover on a hot grill. Let the grill and any coals cool completely first. We cover that, along with NFPA and U.S. Fire Administration grilling guidance, further down.

1. Charbroil Performance Grill Cover, 4 Burner Large: Best Overall

Charbroil’s Performance Grill Cover in the 4 Burner Large size is a universal cover sized by burner count rather than by model. The listing says it’s designed to fit three- and four-burner gas grills, large charcoal grills and smokers up to 62 inches wide, which covers a large share of the cart-style grills on American patios.

Charbroil describes the fabric as an 18mil polyester with a sun fade protective liner. The seams are sealed, which the listing says is for water resistance, and it claims UV protection for fade resistance. Note the word choice: Charbroil calls it water resistant, not waterproof, and the “mil” figure is a thickness rating, a different measure from the denier numbers other brands use.

Day to day, you drape it over a cooled grill and pull it down to the legs. The listing gives the cover’s measurements as 62 inches wide, 42 inches high and 24 inches deep, and the specs list it at 3.8 pounds. The listing doesn’t mention fastening straps, handles or vents, so in a windy yard you may want to tie the corners or check that the cover is snug.

It suits households with a standard mid-size gas grill, a larger charcoal grill or a smoker who want a straightforward cover from a grill maker. Measure your grill’s width with the side shelves in the position you’ll store it, and make sure that number comes in under 62 inches.

Why we like it

• Sized by burner count
• Sealed seams
• Sun fade protective liner

Watch out for

No straps or vents are mentioned on the listing, and the warranty field is empty.

2. Weber Premium Grill Cover for Spirit: Best for Weber Spirit Owners

Weber’s Premium Grill Cover for select Spirit gas grills is made to fit one family of grills rather than a range of widths. Weber says it fits Spirit two-burner and three-burner gas grills manufactured since 2025, plus Spirit and Spirit II two-burner grills manufactured from 2016 through 2024. One bullet also refers to the Spirit II 200 Series.

Weber says UV inhibitors in the fabric resist fading and that the material is both breathable and water resistant, which lets moisture escape rather than trapping it against the grill. Fastening straps keep it in place in strong wind, according to the listing, and Weber describes the cover as lightweight so it goes on and comes off without a struggle.

Care is simple but limited: Weber says to spot clean only, so you won’t be hosing it down or putting it in a washer. The listed measurements are 48 x 27 x 42 inches. The specs list the weight as 0.43 pounds, which seems light for a cover this size, so don’t rely on that number. The warranty field reads “3-year limited warranty. See owner’s manual for more details.”

It suits Weber Spirit owners who would rather buy a cover cut for their grill than measure for a universal one. Check your model and its manufacturing year against the listing before ordering, since fit is the whole point here.

Why we like it

• Cut for Weber Spirit grills
• Breathable fabric
• Three-year limited warranty field

Watch out for

It costs the most here and fits only the Spirit models and years the listing names, so confirm yours first.

3. Weber 22-Inch Charcoal Kettle Grill Cover: Best for 22-Inch Kettles

Weber’s 22-Inch Charcoal Kettle Grill Cover is a round, fitted cover for the classic kettle shape. The listing keeps it short: it fits 22-inch charcoal grills, it’s made from premium heavy duty polyester, and it’s UV and water resistant.

Weber describes the material as breathable and able to withstand the elements. Breathability matters with charcoal grills in particular, because ash and leftover moisture in the bowl can hold dampness, and a cover that lets air through helps the inside dry. Straps help fasten the cover to the grill if it’s windy, according to the listing.

Using it is about as easy as a cover gets: once the coals have cooled completely and you’ve emptied the ash, slip it over the lid and bowl and fasten the straps. The specs list it at 28.5 x 23.5 x 35 inches and 0.64 pounds, light enough to fold into a drawer in summer. The warranty field reads “2 year.”

It suits anyone with a standard 22-inch charcoal kettle, whether it lives on a patio, in a backyard or at a campsite. Owners of larger kettles, smokers or kettles with attached side tables should check sizing carefully, since this cover is made for the 22-inch size only.

Why we like it

• Fitted kettle shape
• Breathable fabric
• Two-year warranty field

Watch out for

It fits 22-inch charcoal grills only, and the listing gives no fabric thickness or denier.

4. Blackstone 5482 36-Inch Griddle Cover: Best Griddle Cover

Blackstone’s 5482 Griddle Cover is made for the brand’s 36-inch griddles with a hood, and the listing says it also fits other models with similar dimensions. Flat-top griddles have a different shape from a domed gas grill, so a griddle-specific cover sits closer to the cooktop and shelves than a universal grill cover would.

Blackstone says it’s made from heavy-duty 600D polyester and weather-resistant materials, with reinforced stitching that the brand says helps prevent leaks and tearing. It’s pitched to stand up to rain, snow, wind and thunderstorms. Cinch straps and plastic clips give a secure fit, according to the listing.

Day to day, wait until the griddle top has cooled, scrape and oil it as you normally would, then pull the cover over the hood and clip it. The specs list a size of 22 x 6.4 x 5.1 inches and a weight of 6 pounds; the size looks like the folded package rather than the fitted cover, and the weight seems high, so treat both with caution. The bullets say it includes a one-year warranty, though the warranty field itself is empty.

It suits Blackstone owners with a hooded 36-inch griddle who want a matching cover. Owners of a 36-inch griddle without a hood, or a 28-inch model, should look at Blackstone’s other cover sizes instead.

Why we like it

• Stated 600D fabric
• Clips and cinch straps
• Strong sales rank

Watch out for

It’s cut for hooded 36-inch griddles, and the listed size and weight look like package figures, not the cover itself.

5. Unicook 60-Inch Heavy Duty Grill Cover: Best Vented Universal Cover

Unicook’s 60-Inch Heavy Duty Grill Cover is a universal cover for bigger grills. The listing gives its size as 60 inches wide, 23 deep and 42 high, and says it fits most brands of three- to five-burner grills up to 58 inches wide, naming Weber Genesis, Char-Broil, Nexgrill, Kenmore, Brinkmann and Broil King.

Unicook describes the fabric as a fade-resistant material with a waterproof vinyl coating that resists UV, rain, tears and cold cracking. The feature that sets it apart is ventilation: wide covered mesh vents on two sides let moisture escape, and Unicook says the airflow also helps stop the cover from blowing away in high winds.

Fabric handles make it easier to pull on and off and double as hanging loops for storage, and straps keep it fastened. Cleaning is a hose-down followed by air drying in the sun. Unicook’s listing also includes the most important instruction of all: always allow the grill to cool completely before covering. The specs list it at 3.3 pounds.

It suits owners of large gas grills, especially in humid or rainy areas where trapped condensation is a concern. Measure your grill’s width first, since the 58-inch limit applies to the grill, not the cover.

Why we like it

• Covered air vents
• Waterproof vinyl coating
• Handles double as hanging loops

Watch out for

The warranty field is empty, and as a universal cover it depends on accurate measuring.

6. Char-Broil 5+ Burner Extra Large Rip-Stop Grill Cover: Best for Extra-Large and Combo Grills

Char-Broil’s 5+ Burner Extra Large Rip-Stop Grill Cover is for the biggest setups on the patio. The listing says it fits five-, six- and seven-burner gas grills, extra-large combo grills, charcoal grills and smokers up to 72 inches wide, and it measures 72 inches wide, 42 high and 24 deep.

Char-Broil calls the fabric an ultra-premium heavy duty 24mil polyester with an interior coating for protection from the elements. Like the brand’s smaller cover, it lists sealed seams for water resistance and UV protection for fade resistance. It adds adjustable-fit side straps for a more secure fit, which matters on a cover this large, since a wide panel of fabric catches a lot of wind.

Putting it on is a two-handed job given the width, but the specs list it at just 2.55 pounds. Wait until the grill and any charcoal or pellet firebox have cooled completely, then center the cover and tighten the straps. The listing doesn’t mention vents or a warranty term.

It suits owners of large gas grills with side burners, gas-and-charcoal combo units and wide smokers, including some pellet grills once you measure across the hopper. If your grill is under about 60 inches wide, a smaller cover will fit more snugly.

Why we like it

• Fits up to 72 inches wide
• 24mil coated polyester
• Adjustable side straps

Watch out for

Its sales rank is the weakest here and the warranty field is empty, so it’s best kept for grills too wide for standard covers.

7. SunPatio 32-Inch 2-Burner Grill Cover: Best Small Grill Cover

SunPatio’s 32-Inch 2-Burner Grill Cover is built for compact gas grills stored with their side shelves folded down. The listing gives its size as 32 inches wide, 24 deep and 43 high and says it fits most two-burner grills with folding side shelves, naming Weber, Charbroil, Nexgrill, KitchenAid and Monument, plus three-burner grills such as Kenmore up to 30 inches wide with shelves folded.

The exclusions are spelled out, which is useful: SunPatio says it does not fit the Weber Spirit II E-210, the Spirit E-210 (2025 new version), or grills with single-fold or non-folding side shelves. If your grill has fixed shelves, it will be too wide for this cover.

SunPatio describes the fabric as its FadeStop material with a waterproof vinyl coating that resists fading, tearing and cold cracking, and says it protects against UV, rain, snow, dust and debris. Two adjustable straps on the sides hold it in place on windy days, and two fabric handles at the top help you pull it on and hang it up. The specs list it at 2.5 pounds.

It suits small patios, townhouse decks and anyone with a two-burner grill that folds down for storage. SunPatio says it replies to questions within 24 hours if you’re unsure about fit.

Why we like it

• Clear fit exclusions
• Waterproof vinyl coating
• Handles and straps

Watch out for

Fold your grill’s shelves and measure before ordering; fixed-shelf grills and some Weber Spirit E-210 models won’t fit.

How We Chose the Best Grill Covers

Every pick was in stock and sold by Amazon.com or the brand’s own store when we checked. From there, we compared what each listing actually says:

• Fit: model-specific covers versus universal covers sized by width or burner count, and any models the listing says it does not fit.
• Fabric claims: denier or mil figures, waterproof versus water-resistant wording and UV claims, attributed to the brand.
• Wind and moisture: straps, clips, handles and vents where the listing mentions them.
• Care: hose-down versus spot clean only.
• Warranty and popularity: the warranty field (flagged where empty) and Amazon sales rank.

Grill Cover Buying Guide

Measure Before You Buy: Sizing by Grill Width

Measure your grill’s width, depth and height in the position you’ll store it, with side shelves folded if they fold. Universal covers list a maximum grill width that’s usually a little smaller than the cover itself: Unicook’s 60-inch cover fits grills up to 58 inches wide, and SunPatio’s 32-inch cover fits grills up to 30 inches with shelves folded. Char-Broil sizes by burner count, from three or four burners (up to 62 inches) to five-plus (up to 72 inches). A good fit reaches close to the bottom of the legs without pooling on the ground.

Best Grill Cover Material: Denier, Mil and Coatings

Fabric numbers aren’t standardized across brands. Denier (written “600D”) describes the weight of the fibers in the weave; Blackstone lists 600D polyester. Char-Broil instead lists thickness in “mil,” 18mil for its large cover and 24mil for its extra-large one. The two units can’t be compared directly, and higher figures from other brands are their own claims. Coatings matter as much as the base fabric: Unicook and SunPatio both list a waterproof vinyl coating, and Char-Broil lists an interior coating on its 24mil cover.

Best Outdoor Grill Cover for Rain, Sun and Wind

Read the water wording closely. Unicook and SunPatio say “waterproof”; Weber and Char-Broil say “water resistant”; Blackstone says “weather-resistant.” For sun, Weber cites UV inhibitors, Char-Broil cites UV protection for fade resistance, and SunPatio calls its fabric FadeStop. In wind, straps or clips matter more than fabric: every pick except the Char-Broil 4 Burner Large lists straps, clips or both.

Vents and Breathability

A fully sealed cover can trap condensation against a grill, which can encourage rust. Unicook is the only pick here that lists covered mesh vents, and Weber describes both of its covers as breathable. If you live somewhere humid, take the cover off to air the grill out after a long wet spell.

Covers for Griddles, Kettles and Pellet Grills

Flat-top griddles and round kettles have shapes that universal grill covers don’t fit well, which is why Blackstone and Weber make dedicated covers for them. If you’re still choosing a flat-top, our gas griddle guide compares sizes and hood options. Pellet grills are wider than they look because of the side-mounted hopper, so measure across the hopper and any shelf; our pellet grill guide covers the main designs. None of our picks names a pellet grill model, so use the widest measurement and pick a universal cover that clears it.

Gas Grill Covers by Brand Fit

A model-specific cover, like Weber’s for the Spirit, should fit closely with no guesswork, but only for the models and years the listing names. Universal covers cost less and fit many brands; they just depend on your measurements. If you’re still shopping for the grill itself, our best gas grill guide compares burners, grates and warranties, and you can buy a cover sized to the grill you choose.

Cool Before You Cover: Grill Fire Safety

A cover goes on a cold grill, never a warm one. Unicook’s listing says to “always allow the grill to cool completely before covering,” and the same logic applies to every cover here: fabric and vinyl don’t belong on hot metal or smoldering coals. The NFPA’s grilling safety page and the U.S. Fire Administration’s outdoor fire page add the habits that prevent most grill fires:

• Let coals cool completely. NFPA says to let coals cool completely before disposing of them in a metal container, and USFA says to put cooled coals in a metal can with a lid.
• Clean the grease. NFPA says to remove grease or fat buildup from the grill and the trays below it, and reports that the grill had not been cleaned in roughly one-fifth of grill fires.
• Keep it away from the house. NFPA says to place the grill well away from the home and deck railings and out from under eaves and overhanging branches. USFA adds: don’t store or use a grill on a porch or balcony.
• Outdoors only. USFA says to use propane, charcoal and wood pellet grills only outside, because indoor use can cause a fire or carbon monoxide poisoning.
• Never walk away. NFPA says never to leave a grill unattended when in use, and to keep children and pets at least three feet from the grilling area.

NFPA also reports that gas grills were involved in an average of 9,235 home fires per year, and that July was the peak month for grill fires.

Grill Fires and Your Home Insurance

A grill fire that spreads to siding, a deck or a fence is a property claim, and storing a grill against the house raises that risk. Homeowners policies generally cover fire damage from a covered loss, but limits, deductibles and exclusions vary, and renters should check whether their lease allows grills on patios or balconies at all. Our Ohio homeowners insurance guide and renters insurance costs in Ohio explain what to look for before grilling season.

Frequently Asked Questions

What is the best grill cover for most gas grills?

The Charbroil Performance 4 Burner Large is our overall pick. It’s sold by Amazon.com, ranks #39 in Grill Covers, and its listing says it fits three- and four-burner gas grills, large charcoal grills and smokers up to 62 inches wide.

What is the best grill cover material?

Polyester with a coating is the norm. Blackstone lists 600D polyester, Char-Broil lists 18mil and 24mil polyester, and Unicook and SunPatio list a waterproof vinyl coating. Brands use different units, so compare fit, seams, straps and coating rather than one number.

Should a grill cover be waterproof or breathable?

Ideally both. A waterproof coating keeps rain out, but trapped moisture can condense underneath. Unicook adds covered mesh vents, and Weber describes its covers as breathable and water resistant.

Can I put a cover on a hot grill?

No. Let the grill cool completely first; Unicook’s listing says to always allow the grill to cool completely before covering. With charcoal, NFPA says to let coals cool completely before disposing of them in a metal container.

How do I measure for a grill cover?

Measure width, depth and height with any folding shelves in their storage position. For universal covers, check the maximum grill width the listing gives, such as up to 58 inches for the Unicook 60-inch or up to 72 inches for the Char-Broil 5+ Burner.

The Bottom Line

For most mid-size gas grills, the Charbroil Performance 4 Burner Large is the best grill cover to start with: sized by burner count, sealed seams and sold by Amazon.com. Weber Spirit owners get an exact fit and a three-year limited warranty field from the Weber Premium cover, 22-inch kettles have Weber’s fitted kettle cover, and hooded 36-inch Blackstone griddles have the Blackstone 5482. The Unicook 60-inch adds vents for damp climates, the Char-Broil 5+ Burner stretches to 72 inches, and the SunPatio 32-inch suits small grills with folding shelves. Measure first, and only cover a cold grill.
