What Size Propane Tank Do You Need?

You have probably heard propane referred to in pounds: 20 lb tank, 33 lb tank, 100lb and so on. That refers to the weight of the tank when it’s full of propane. But understanding how much propane that is can be confusing. This also makes it difficult to know how big a tank you will need. After all, we typically measure liquids in gallons, not by weight.

To help you better understand what size tank you need, here is a breakdown of common propane tank weights/sizes, how many gallons are in each, and common uses of each.

Common Propane Tank Sizes and Their Uses

Important: propane tanks are often only filled to 80% capacity to allow the propane to safely expand. Even when it is full, a propane gauge will only read 80%.

20 lb, 30 lb, 40 lb Tanks

  • Typically used for grilling and patio heaters
  • Holds 5 gallons of propane
  • Very portable, easy to pick up
  • Refill by stopping by our office conveniently located in Old West Durham 2907 Hillsborough rd

33 lb Tank

  • Used to power forklifts
  • 2’ tall, 1’ in diameter
  • Holds 8 gallons of propane
  • Can be picked up and moved by one person

100 lb Tank

Two 100 lb Tank Setup

  • Two 100 lb tanks are connected with a switchover valve
