How to Choose the Right Custom Standard Grill Cover for Your BBQ

Standard grill covers protect the workhorse of the American backyard — the freestanding grill. Wheels, side shelves, propane tank hanging off the back, a lid handle that's been closed and opened a thousand times. It moves with the sun, gets rolled off the patio for lawn cleanups, and comes back into the same spot next weekend for the next cookout.

None of that motion is a problem when the grill is being used. It becomes a problem when it's not — because the cover that protects the grill between cooks has to account for every one of those moving parts. Off-the-shelf standard grill covers are cut to a nominal length and hope for the best. The wheels catch under the hem. The side shelves poke against the fabric at the corners. The propane tank throws off the depth measurement by six inches.

Custom standard grill covers are what solve every one of those fit problems, and the ordering conversation is straightforward: three measurements taken correctly, a fabric weight that holds up outdoors, and a few securing details chosen for how much wind your patio actually sees. This guide walks through each part, plus how a freestanding grill cover differs from a built-in one and why that difference matters.

What Standard Grill Actually Means (and How It Differs from Built-in)

In ZIPCovers terminology, standard grill covers protect any freestanding grill unit — the kind you can roll from one spot to another. Weber Spirit and Genesis lines. Traeger pellet grills. Char-Broil, Nexgrill, Napoleon, Kamado Joe standalones. Anything with wheels and a base.

Built-in grill covers work differently — they protect the grill heads that sit permanently into an outdoor kitchen island: no legs, no wheels, no propane tank attached. Built-in grill covers drop down over the head only and stop at the countertop line.

Standard grill covers, by contrast, go the full way down. From the top of the hood, over the side shelves, past the control panel, down to just above the patio surface — clearing the wheels but not dragging on the ground. That envelope is why standard grill covers are almost always more complex to fit than built-in covers, even though the grill itself might look simpler.

The Three Measurements That Fit a Standard Grill

1. Width — from outer edge of one side shelf to the other

This is the most-often-mismeasured dimension on a freestanding grill. The grill body itself is usually 32 to 46 inches wide. But the side shelves — the flat surfaces where you'd set a plate of raw chicken or a set of tongs — add anywhere from 6 to 14 inches on each side.

Measure with the side shelves in whatever position you'll store the grill. If you leave them folded up against the sides for storage, measure with them folded up. If you leave them extended, measure extended. If your grill sometimes has them up and sometimes down, take the larger measurement and let the drawstring take up the slack when they're folded.

For grills with side burners built into one of the shelves (common on higher-end Weber Genesis and Napoleon Prestige lines), the burner side is usually 1 to 2 inches wider than the plain shelf side. The cover needs to clear the widest span, so measure across the widest point of the whole unit — burner side included.

2. Depth — front control panel to back of hood

Depth on a standard grill runs from the front — where the control knobs sit — to the back of the hood. Most grills are 24 to 28 inches deep at the body, but the actual cover depth needs to be larger because of two things: the front handle and the propane tank.

The lid handle sticks forward by 2 to 4 inches on most grills. That handle is what makes the front of the cover pull tight and eventually rub through if the cover is cut to the grill body alone. Include the handle in the depth measurement.

The propane tank is trickier. It hangs off the back of the grill on most freestanding units, adding another 8 to 12 inches to the effective depth. If you cover the grill with the tank attached, measure to the back of the tank. If you disconnect and store the tank separately, measure to the back of the grill body itself. Either way, the number you enter has to match what the cover is actually going over.

3. Height — ground to top of hood

Straight vertical measurement from the patio surface to the highest point of the closed hood. For most standard grills this is 42 to 52 inches. Weber Genesis runs about 47 inches. Traeger pellet grills run taller, often 48 to 52 inches. Kamado-style grills are shorter but rounder, usually 40 to 44 inches.

Add 1 inch of ground clearance to the height number before entering it. That gap keeps the hem from dragging on the patio, lets airflow underneath so humidity doesn't get trapped against the grill body, and prevents the cover from wicking moisture up when the patio surface is wet after a rain.

Don't include the propane tank height if the tank hangs off the back rather than sitting under the grill. On most freestanding units, the tank is behind and below the grill body — the cover doesn't need to clear its height, only its depth.

The Wheel Problem (and How Custom Fixes It)

Every freestanding grill has wheels — usually two locking casters at the front and two fixed wheels at the back. Off-the-shelf covers ignore this and just extend down to the patio surface. The result: the wheels catch under the hem every time the cover goes on. Two or three tugs to work it into position. A frayed section at each wheel point after a season.

Custom fixes it by cutting the cover to your actual grill's height, with the 1-inch ground clearance built in. The hem sits just above the wheel line — clear of the casters but low enough to seal against wind and rain. For grills with taller-than-standard wheels (some heavy-duty Traeger and Kamado carts have 6-inch wheels), the ground clearance can be bumped up to 1.5 or 2 inches in the order notes. Customer-care will adjust the cut.

Why 18 oz PVC Is the Right Fabric for a Freestanding Grill

Grill covers face more direct temperature swings than any other outdoor cover. The grill body itself can hold residual heat for hours after use. The cover goes on over that residual warmth. Then it sits through overnight temperature drops of 30 to 40 degrees. Cheap polyester covers can't handle that thermal cycling for long — they get brittle at the fold lines within a couple summers.

18 oz 1000 Denier PVC-coated polyester — the Zip Armor line — handles it. The PVC coating stays flexible across the whole temperature range, and the seams are heat-welded rather than stitched so there are no needle holes for water to find. For grills that live under a covered patio roof and only see indirect weather, the lighter Zip Shield line works. For open-yard installations, Zip Armor is the choice.

Ventilation grommets are the other detail that separates grill covers from other cover types. Sealed covers trap humidity from the residual heat, and trapped humidity is what creates the slow rust line most freestanding grills develop after a few seasons of use. The grommets sit on the side panels at hood level — high enough that rain doesn't track in, low enough that hot vapor escapes as the grill cools.

Cover Habits That Extend a Freestanding Grill Cover's Life

The single most important habit for any grill cover: let the grill cool fully before covering. Not just cool to the touch on the hood — cool through the body and internal parts. On a hot summer day, that means waiting 45 minutes to an hour after the last burner is off.

Covering a warm grill chalks the interior of the PVC over time. The plasticizer in the coating breaks down against heat, and the cover develops a dull, powdery interior that's the tell-tale sign of a cover-too-warm habit. Wait it out. Cover it once, cover it right, and the cover lasts a decade.

Once a season, lift the cover off, hose both sides down with a garden hose, and let it air-dry in the sun. For grease spots on the underside — usually splatter from cook nights that got trapped when the cover went on — a paste of baking soda and warm water lifts most of it. Skip degreasers and dish detergents on the outside; both strip the UV coating and shorten the cover's working life.

Check the ventilation grommets once a season too. Leaves and bugs sometimes block them, and clogged vents mean the humidity that should be escaping stays trapped inside. A blast of compressed air clears them in seconds.

Placing the Order and What to Expect

Enter your three numbers on the Custom Standard Grill Cover product page — width across the widest span (side shelves included), depth from the front handle to the back of the hood (or the propane tank if you store it attached), and height with the 1-inch ground clearance added.

Choose the fabric weight — Zip Armor for open-yard year-round use, Zip Shield for covered-patio installations. Pick your securing option: bottom drawstring is standard on every cover, leg-buckle straps are the no-cost upgrade for any patio that sees real wind. If your grill lives near a coast, a hilltop, or anywhere summer storms roll through with intent, order the buckles.

Customer-care reviews the numbers before the vinyl is cut. If your dimensions look unusual for a standard grill — a width that's much smaller than typical, a depth that reads more like a griddle than a full grill — they'll email or chat you back to confirm before anything is touched.

Once the cover ships, tracking arrives by email. The 10-year warranty on the Zip Armor line covers manufacturer defects — seam separation, coating failure, cover-fit issues. If anything doesn't read right when the cover arrives, customer-care will work it out at sales@zipcovers.com or +1 720-882-0756.

Frequently Asked Questions

Should I measure my grill with the side shelves folded or extended?

Measure with the side shelves in the position you'll store the grill in. If you leave them folded up against the sides for storage, measure with them folded. If you leave them extended (say, because your grill sits under a patio roof with room to spare), measure extended.

If it varies — sometimes up, sometimes down — take the larger measurement and let the drawstring take up the slack when the shelves are in the smaller position. A cover cut to the narrower dimension will pull tight and eventually tear at the shelf corners when the shelves are extended.

Do I include the propane tank in the depth measurement?

Depends on whether you cover the grill with the tank attached. On most freestanding grills, the propane tank hangs off the back of the unit and adds 8 to 12 inches to the effective depth. If you leave the tank connected and covered under the grill cover, include it in the depth measurement.

If you disconnect and store the tank separately (a common habit for anyone who worries about propane exposure to the sun), measure to the back of the grill body itself. The number you enter has to match what the cover is actually going over — get it wrong and either the cover doesn't clear the tank, or it drapes loosely at the back.

How do I prevent rust under a grill cover?

Three habits handle most of it. First, let the grill cool fully before covering — hot metal condenses trapped humidity into the cover interior, and that humidity is what starts rust lines on any exposed steel. Second, check the ventilation grommets on the sides of the cover once a season and clear any leaves or bugs blocking them. Clogged vents defeat the whole point of the grommets.

Third, once a season, lift the cover off and let both the grill and the cover interior fully air out in the sun for an afternoon. That single habit resets any trapped humidity that's built up over months.

Can you make a cover for an unusual grill shape?

Yes — custom covers ship in any size and shape, including L-shaped outdoor kitchens with a grill on one leg, Kamado-style dome grills, pellet grills with attached hoppers, and grills paired with side burners on separate carts. For anything that doesn't match a standard rectangular grill footprint, use the Custom Shape product page and upload a sketch with dimensions marked on each edge.

For very unusual shapes (like a pellet grill with an extended side hopper), send a photo along with the measurements. Customer-care can confirm the intent before the vinyl is cut. Reach the team at sales@zipcovers.com or +1 720-882-0756.

What is the warranty period on a Zip Armor grill cover?

The ZIP Armor line — 18 oz 1000 Denier PVC-coated polyester — carries a 10-year warranty. The lighter ZIP Shield line carries a 7-year warranty. Both warranties cover manufacturer defects (seam separation, coating failure, cover-fit issues). They don't cover damage from mishandling (a grease fire that scorches the cover, a garden shear cut, a sharp object dropped on top). To make a claim, email sales@zipcovers.com with photos of the issue and your order number.

Build Your Standard Grill Cover

A freestanding grill cover that fits right doesn't look like a cover struggling to hold its shape. It looks like the grill is wearing the profile of the grill underneath, slightly softened at the edges. The wheels sit clear. The side shelves have room. The propane tank fits under. When it's on, it looks intentional.

Take the three numbers with the side shelves in the position you'll store the grill in. Add the 1-inch ground clearance. Pick the buckle upgrade if you're anywhere real wind reaches. Place the order and the cover will work on day one. Still working on day 1,000.
