What size propane cylinders are typically used for residential purposes?

The commonly used propane cylinders for residential purposes are the 20-pound and 30-pound cylinders. These sizes are ideal for home applications such as grilling, heating, and other recreational needs. A 20-pound cylinder is often used for typical barbecue grills, while a 30-pound cylinder can provide a longer duration of use for larger appliances or extended grilling sessions.

Choosing these sizes makes practical sense for homeowners, as they strike a balance between capacity and portability. The smaller and more manageable size allows for easier handling when transporting or replacing the cylinders, making them suitable for regular use in household settings. Other cylinder sizes, such as 10-pound or 15-pound options, may be less common, while larger sizes like 40-pound, 50-pound, or 100-pound cylinders tend to be reserved for commercial applications or situations requiring larger propane capacity, such as heating large spaces or powering multiple appliances simultaneously.
