Best Grill Covers (2026)

A grill cover is the cheapest insurance you'll ever buy for an expensive grill. Sun, rain, and grime are what actually kill grills — rusting grates, fading finishes, and corroding burners — and a $30 cover prevents most of it. The catch is fit and fabric: a cover that's too loose blows off, and a thin one tears in a season. We picked three that get it right. Weber's tailored cover is the best match for Weber grills, the Unicook universal is the value pick that fits almost anything, and the ULTCOVER is the heavy-duty choice that feels a tier above its price.

How We Picked These

For this grill cover guide, we applied the framework laid out in our Editorial Policy: we evaluate materials and construction first, then weight long-term durability heavily — six-month and one-year owner-review patterns matter more than first-week impressions. We screened out products with documented reliability complaints, missing or hard-to-claim warranty support, and no-name brands without long-term service infrastructure. The picks below are the ones we'd recommend to a friend.

1. Best Overall: Weber Premium Outdoor Grill Cover

2. Best Value: Unicook 55-Inch Heavy Duty Waterproof Grill Cover

3. Best Premium: ULTCOVER 52-Inch Waterproof Heavy Duty Grill Cover

What to Look For

Measure your grill, then match the size. The single most common mistake is buying the wrong dimensions. Measure width, depth, and height with the lid closed and any side tables out, then pick a cover that's slightly larger so it slips on easily and breathes. A too-tight cover is a daily fight; a too-loose one catches the wind.

Fabric weight and waterproofing matter most. Look for heavy denier polyester (600D is a good benchmark) with a waterproof backing or coating and sealed seams. 'Water-resistant' sheds a drizzle; 'waterproof' survives a storm. UV resistance keeps the fabric from going brittle and fading after a summer in the sun.

Straps and vents are what keep it on and dry. Fastening straps or a drawstring hem stop the cover from blowing off in wind — the leading cause of a 'lost' cover. Air vents let heat and moisture escape so condensation doesn't pool inside and cause the very rust you're trying to prevent.

Tailored vs. universal fit. A brand-tailored cover (like Weber's) hugs the grill's exact shape for the best look and wind resistance, but only fits specific models. A universal cover sized by width fits a huge range of grills and costs less — just confirm your grill falls within its dimensions before buying.

Buyer Scenario Decision Matrix

Stop comparing specs. Start with what you're actually doing, then the right product is obvious:

Frequently Asked Questions

Do grill covers prevent rust?

They dramatically reduce it. A waterproof cover keeps rain and snow off the grates, burners, and firebox, which is what causes most rust. The key is venting — a cover with air vents lets trapped moisture escape, while a sealed-up cover over a damp grill can actually hold humidity against the metal. Cover a dry, cool grill, not a hot or wet one.

What size grill cover do I need?

Measure your grill's width, depth, and height with the lid down and side shelves in their normal position, then choose a cover slightly larger than those numbers. Covers are usually sold by width (for example, 55 inches). A little extra room makes it easy to put on and lets air circulate; too snug and it's a struggle.

Should I cover my grill when it's hot?

No — always let a grill cool completely before covering it. A hot grill can melt or scorch the cover and traps steam and heat that promote rust and mildew. Wait until the grill is cool to the touch, ideally also dry, then put the cover on.

Are expensive grill covers worth it over cheap ones?

Up to a point. A mid-priced, heavy-denier waterproof cover with straps and vents will outlast a flimsy bargain cover several times over, so it's worth spending a bit. Beyond that, a brand-tailored cover mainly buys you a better fit and look — nice on a premium grill, but a quality universal cover protects just as well.

What is the top-rated grill cover for 2026?

Our top-rated pick is the Weber Premium Outdoor Grill Cover. Weber's own water-resistant cover — a tailored fit, fastening straps, and UV-resistant fabric made to match Spirit and Genesis grills.

Which grill cover is best for beginners or a tighter budget?

The best-rated value pick is the Unicook 55-Inch Heavy Duty Waterproof Grill Cover — The best-selling universal cover — heavy-duty and waterproof, it fits most 2-3 burner gas grills for a fraction of a branded cover.

Best heavy-duty grill cover?

Classic Accessories Ravenna Series and Weber Premium Covers — both 600D fabric with reinforced seams that survive wind, rain, and UV for 3-5 years. Cheap covers tear or fade in a single season.

What size universal grill cover should I get?

Measure your grill (width × depth × height with lid closed and side tables out) — universal covers are sized 55, 65, or 72 inches wide. Get one 2-3 inches longer than your measurement so it slides on and off easily.
