| Fuel | Charcoal plus wood chunks. |

| Why people buy it | The 22 buys much more horizontal room, which matters for full briskets and untrimmed rib racks that feel cramped on smaller round grates. |
What actually fits — and when the advertised area matters
Weber says the 22-inch model fits six racks of ribs. The more useful question is whether you normally cook one large centerpiece cut, several racks of ribs, or a mixed party load. Horizontal grate width matters for brisket and ribs; vertical rack count matters more for chicken pieces, jerky and sausage. Do not buy unused steel just because the total square-inch number looks impressive.
For a normal family cook, leave some empty space around the meat. Air and smoke still need to move, and crowding every advertised inch often produces a worse cook than using 70–80% of the available area. The larger model earns its keep when you repeatedly run out of room, not when you merely like the idea of having more room.
Cooking experience
The 22-inch diameter changes brisket life
Square inches are not the important part here; diameter is. Full packer briskets and long rib racks sit more naturally on a 22-inch circle, which means less folding, trimming and edge exposure.
Two grates are useful, not equally convenient
The lower grate adds real capacity but requires more work to access mid-cook. Plan the slowest/least-touched meat down low and the food you expect to wrap, spritz or probe on top.
Temperature control is mechanical and learnable
Bottom vents meter oxygen; the top vent normally stays open. Once charcoal is lit and the water pan/diffuser system stabilizes, a WSM can cruise for hours with surprisingly little intervention.
The larger body burns more fuel
You are heating a larger steel cylinder and more air. In cold or windy weather, the 22's appetite becomes more obvious. A windbreak often improves performance more than throwing extra charcoal at the problem.
Reliability is the anti-electronics argument
There is no controller, fan, auger or app required. A thermometer can fail without ending the cook. That mechanical simplicity is a major reason WSMs remain relevant.
Cleanup is mostly ash and grease
The cooker is simple, but the water pan can become the annoying piece. Foiling it or using a dry-pan strategy can make post-cook cleanup significantly easier.
Ownership: fuel, cleanup, weather and the stuff spec sheets skip
Fuel is part of the purchase price
A smoker is not a one-time expense. Pellets, lump charcoal, briquettes, wood splits and proprietary smoke media have very different costs and storage needs. More important than the exact dollars per cook is whether the fuel is easy to buy near you and whether you are willing to keep it dry. A bargain smoker that needs specialty fuel you hate sourcing is not a bargain for long.
Capacity claims need translation
Square inches are useful, but grate shape matters. A round 18-inch kamado can have enough square inches on paper yet feel cramped around a full packer brisket. A vertical electric cabinet can advertise huge total rack area but force you to cut rib racks. We therefore translate area into the foods people actually cook: briskets, racks of ribs, pork shoulders and chickens.
Weather exposes weak insulation
A smoker that behaves beautifully at 75°F can become annoying in wind or near-freezing weather. Ceramic kamados and thick steel shrug off cold better than thin cabinets. Pellet and electric units compensate with thermostatic control but may burn more fuel or electricity. If you cook year-round, insulation belongs high on the buying list.
Automation changes the hobby
A thermostat, fan controller or pellet auger does more than hold temperature: it changes how you spend the cook. Some people want to tend a fire because fire management is the point. Others want to sleep during an overnight brisket. Neither is more authentic; buy the machine that matches the experience you actually want.
What works
- 726 sq in and a genuinely useful 22-inch grate
- Six-rack-of-ribs capacity per Weber
- Simple, durable charcoal design
- No electricity required
- Excellent smoke flavor with charcoal and wood chunks
What to know first
- Uses more charcoal than the 18
- Large body is harder to move/store
- Lower grate access can be awkward
- No automation unless you add a fan controller
- Water-pan cleanup can be messy
Who should buy the Weber Smokey Mountain 22?
You cook packer briskets often
The 22's grate diameter is the practical reason to upgrade.
You feed groups with ribs or pork shoulder
Weber's six-rack capacity gives real party usefulness.
You want a smoker that can last decades
Porcelain-enamel construction and the absence of electronics make the WSM a long-horizon purchase.
Skip it if you mainly cook for two
The 18 is easier on fuel and still handles serious barbecue.

Use the exact model name when shopping. Smoker families often include older revisions, bundles and similarly named sizes with different controllers or accessories.
Before you click Buy: the five-minute smoker check
Measure the patio. Use lid-open dimensions, not just the footprint with everything folded. Leave manufacturer-required clearance from siding, railings and combustible structures.
Price the fuel. Look at what pellets, lump charcoal, briquettes or hardwood splits actually cost near you. Shipping a specialty fuel every month changes the ownership economics.
Check the outlet question. Pellet grills, gravity-fed digital charcoal cookers and electric smokers require power. Make sure the outdoor circuit and weather protection make sense where the cooker will live.
Read the return policy for freight-sized items. A 150–250 lb smoker is not like returning headphones. Damaged boxes, assembly defects and freight returns can become expensive. Inspect the package and major components before throwing away shipping material.
Buy a thermometer before accessories. A good instant-read thermometer and one or more leave-in probes improve cooking more than decorative shelves, branded tools or a mountain of rubs. The smoker makes heat and smoke; the thermometer tells you when the food is actually ready.
Frequently asked questions
How many ribs fit?
Weber lists six racks of ribs.
Do I need the water pan full?
Not always. Owners use water, sand, foil or a dry pan depending on temperature strategy; follow safe setup practices.
Can I automate a WSM?
Yes. Aftermarket fan controllers can regulate airflow while preserving the charcoal cooking system.
Is the 22 better for brisket?
Its larger diameter makes full packer briskets easier to position without folding or aggressive trimming.
