Key Takeaway: For most home smokers, the 18-inch Weber Smokey Mountain Cooker is the sweet spot. It holds enough food for a family or small party, uses less charcoal than the 22-inch, and is easier to control temperature-wise. Go 22-inch only if you regularly cook for 12+ people.

Weber Smokey Mountain Buying Guide

Size Matters: 18 vs 22 vs 14

The 18-inch is the most popular because it handles everything from a single brisket to a couple of pork shoulders. The 22-inch is for serious volume (up to 6 racks of ribs) but uses about 50% more charcoal and can be harder to stabilize temperature, especially in wind. The 14-inch is compact and portable but limited to small cooks like a single chicken or a few sausages.

Key Features to Look For

All WSMs have a similar design: charcoal ring, water pan, and two cooking grates. The porcelain-enameled steel body resists rust if cared for. The door is a common weak point; some owners add a gasket to seal it. The lid thermometer is often inaccurate, so many users replace it with a digital probe. Built-in vents on the bottom and lid allow airflow control.

Accessories and Mods

To improve performance, consider adding a gasket kit for the door, a better thermometer, and a charcoal basket (instead of the standard ring) for easier ash removal. A cover is essential to protect from weather. For the 22-inch, a hinge kit makes the heavy lid easier to lift.

Safety Notes

  • Place smoker on a stable, non-combustible surface away from structures.
  • Use charcoal and wood chunks only; never use lighter fluid after lighting (use a chimney starter).
  • Keep children and pets away from hot surfaces; the exterior gets very hot.
  • Allow all coals to fully extinguish before disposing of ash in a metal container.

What to Avoid

  • Cheap offset smokers that require constant attention and leak heat.
  • Electric smokers if you want authentic smoky flavor (they produce less smoke).
  • Pellet grills if you prefer hands-on control over smoke and temperature.
  • Used WSMs with rust holes or heavily warped doors; these are hard to seal.

FAQ

How long does charcoal last in a Weber Smokey Mountain?

Depending on temperature and wind, a full load of charcoal in the 18-inch can last 10-14 hours at 225°F. The 22-inch burns through fuel faster, typically 8-10 hours.

Can I use the WSM as a grill?

Yes, you can remove the water pan and place the charcoal ring directly on the bottom grate for high-heat grilling. However, it’s not as versatile as a dedicated kettle grill.

What size brisket fits in the 18-inch?

A 12-14 pound full brisket fits on the top grate with some trimming. For larger briskets, the 22-inch is better.

Final Verdict

The Weber Smokey Mountain Cooker 18-inch is the best choice for most home smokers, offering excellent temperature control and efficiency. For larger crowds, the 22-inch provides extra space at the cost of more charcoal. Both are built to last.
