For the Weber Smokey Mountain 18 vs 22, choose the 18-inch cooker for a lighter, smaller setup or the 22-inch model for more room for large items. Both use charcoal, have 2 cooking grates and adjustable dampers for airflow control.

The 18-inch measures 19 x 21 x 41 inches and weighs 39.1 lb. The 22-inch measures 24 x 23 x 48.5 inches and weighs 68 lb, so plan for the larger cooker’s space and weight before ordering.

The 18-inch can accommodate a whole turkey and an entire ham at the same time, according to Weber. The 22-inch is a stronger fit when you want more room to arrange large items across its grates.

Weber Smokey Mountain 18 vs 22: which size should you choose?

Choose the 18-inch model for a lighter cooker and the 22-inch model for extra room during large cooks. The right size depends on what you cook most, how much patio or storage space you have, and whether you need to move the smoker often.

The 18-inch is a practical match for regular backyard cooks who want two levels without the larger body. Its two 18.5-inch-wide nickel-plated grates give you room to cook on both levels, and Weber says the cooker can fit a whole turkey and a whole ham at once.

The 22-inch suits cooks who often prepare larger items or want more room to arrange food. Its removable aluminum fuel door also makes it easier to add charcoal or wood while smoking.

Is the Weber Smokey Mountain 18 big enough?

The 18-inch model can suit substantial cooks, including a whole turkey and an entire ham at once. It has two grates, and the smaller body makes it easier to place than the 22-inch version.

A grate’s nominal width doesn’t describe how every cut will fit. Consider the length and shape of your usual brisket, ribs, poultry or cookware, and how you like to arrange food across two levels.

Choose the 18-inch if you mostly cook for a household or a modest group and want a charcoal smoker that’s easier to place and move. Skip it if your routine regularly calls for multiple bulky cuts and you want extra working room for arranging them.

When does the 22-inch model make sense?

The 22-inch model makes sense when your cooks regularly need extra room for large items. Weber describes its two grates as providing space to smoke two large items at once.

That extra room comes with a larger, heavier body. The 22-inch is 68 lb and almost 49 inches high, so it’s best for a stable cooking spot with enough room around it.

Pick it if you plan to smoke for larger groups, often cook bulky food, or prefer more space for arranging items. Skip it if you need to carry the smoker through tight routes or store it in a cramped area.

How much space do the 18-inch and 22-inch smokers need?

The 18-inch model has the smaller dimensions, but both need working room around the body. Measure the spot where the smoker will sit and leave space to reach the lid, vents and fuel access.

The 18-inch measures 19 inches deep, 21 inches wide and 41 inches high. The 22-inch measures 24 inches deep, 23 inches wide and 48.5 inches high.

Use tape or cardboard to mark each footprint before choosing. Check nearby walls, outdoor furniture, plants and overhangs, then follow Weber’s manual for safe placement and clearance instructions.

The delivery route matters too. Measure gates, steps and storage doors, especially if you can’t leave the smoker in its cooking area.

What does the weight difference mean?

The 22-inch is 28.9 lb heavier than the 18-inch, so it suits a more permanent cooking spot. The 18-inch weighs 39.1 lb, while the 22-inch weighs 68 lb.

Think about who will move the smoker, how often it will be moved, and whether the path has steps or narrow turns. Set the location before assembly if you expect to keep it in one place.

Weight isn’t the only factor in handling: the body dimensions and your route also matter. If frequent repositioning is part of your routine, the 18-inch is the more manageable choice between these two.

What features matter when comparing the two sizes?

Both cookers use charcoal, have two grates and rely on adjustable dampers, but their included features differ. Choose based on which details help with your cooking routine.

The 18-inch includes a water pan, thermometer and individual vents on the bowl and lid. Its grates are nickel-plated, each 18.5 inches wide, and its body is porcelain-enameled steel.

The 22-inch has a silicone temperature grommet to monitor the smoker’s internal temperature. Its large aluminum fuel door comes off to make adding charcoal or wood easier during a cook.

A water pan, temperature access and fuel door each affect setup in a different way. Read the instructions for your exact size before the first cook so you know how the parts fit together and where to monitor temperature.

What do dampers and a water pan do?

Dampers control airflow, which is one of the main ways to manage heat in a charcoal smoker. The 18-inch has vents on both the bowl and lid, while the 22-inch also has adjustable dampers.

Start with the manual’s recommended setup, then make small vent changes and allow time for the smoker to respond. Large, frequent adjustments make it harder to see what each change does.

The 18-inch water pan is part of its included setup. Follow Weber’s instructions for its use and placement, and keep a reliable temperature reading in view during a cook.

For a first charcoal cook, follow our guide to using a charcoal smoker. Weber’s Smokey Mountain product information can help you confirm the details for the size you’re considering.

Which size is easier to fuel and manage?

The 22-inch makes mid-cook fuel access simpler with its removable door, while both sizes require attention to charcoal and airflow. Choose the fuel access and controls that best fit how long and how often you cook.

The door on the 22-inch comes off to make adding charcoal or wood easier while smoking. On the 18-inch, individual vents at the bowl and lid give you airflow controls at both ends of the cooker.

Before lighting, arrange charcoal and smoking wood, check that the vents are clear, and keep a safe place ready for ash once it has fully cooled. Our guide to lump charcoal vs briquettes for smoking explains the two common fuel choices.

The charcoal and smoker care guide covers fuel handling and routine maintenance. Don’t add fuel or adjust vents in a rush; make one change at a time and give the cooker time to respond.

How should you set up your Weber Smokey Mountain?

Set up the smoker on a stable, suitable outdoor surface with room to work, then follow the manual for assembly and clearance. Check that the cooking grates, water pan if included, vents and fuel access are correctly placed before lighting.

Start with the fuel amount and lighting method in the manual for your model. Keep the lid and vents accessible, and place the smoker where you can monitor it without moving it during the cook.

Allow time for temperature to settle before adding food. Adjust airflow gradually, watch the temperature through the cook, and make notes about your charcoal load and vent positions so you can repeat a setup that works for your conditions.

What common mistakes should you avoid?

Most avoidable problems come from poor placement, rushed vent changes or choosing a size without measuring. A little planning makes the cook easier to manage.

Don’t pick the 22-inch only because it is larger. If you cook smaller batches and need to carry or store the cooker often, the added size and weight can become a daily inconvenience.

Don’t assume the 18-inch will fit every cut simply because Weber says it can hold a whole turkey and ham at once. Compare the shape of your food with the usable grate area and leave room for airflow.

Avoid making several vent changes in quick succession. Make one small adjustment, wait for the temperature to respond, then decide whether another change is needed.

Don’t place either model where you can’t reach the lid, vents or fuel door. Measure the work area and access path, and follow the manual’s placement guidance.

Is the Weber Smokey Mountain 14 a better fit?

The 14-inch Weber Smokey Mountain is the compact alternative when both larger models feel too bulky. It weighs 23 lb and measures 14.7 x 14.7 x 31.4 inches.

It still has two cooking grates and adjustable dampers. The smaller body suits tighter patios or storage areas, but its grate space may be limiting if you often cook for a group or smoke large cuts.

Compare all three sizes with other charcoal smokers for backyard cooks. If you’re considering a different charcoal design, our Weber Smokey Mountain vs Oklahoma Joe’s Bronco comparison explains how the two designs differ.

How should you choose between the Weber Smokey Mountain 18 and 22?

Choose by your largest regular cook, the space available and how often you’ll move the smoker. The 18-inch is lighter and smaller; the 22-inch offers more room for large items and easier mid-cook fuel access.

Pick the 18-inch if you want two grates, a water pan and thermometer, and a lighter cooker that’s easier to place. It’s the better fit for smaller cooking areas and cooks who don’t need extra room for bulky batches.

Pick the 22-inch if you often smoke large items or want more space to arrange food across the grates. Make sure its 68 lb weight, height and footprint work for your route, storage and cooking spot.

Which Weber Smokey Mountain size fits your cooking plans?

For the Weber Smokey Mountain 18 vs 22, buy the 18-inch for a lighter, smaller setup and the 22-inch when extra room for large cooks matters more. If space is especially tight, the 14-inch is the compact alternative.

Start with the biggest food you regularly cook, then measure the smoker’s intended location and the route to get it there. If the 22-inch fits and you want room for large items, choose it; if not, the 18-inch is the more manageable everyday size.
