What size propane tank should I use for my grill?
Quick answer
Standard 20 lb propane tanks fit most cart grills and portable setups — they are the default at exchange cabinets and refill stations. Larger 30–40 lb tanks suit high-BTU built-ins or long sessions but need stable mounting and may require longer hoses; never use oversized tanks without verifying cart weight limits and code.
Common sizes
- 20 lb: everyday backyard grilling
- 30–40 lb: extended cooks, some built-ins
- 1 lb disposable: portable camp grills only
