If you want to install a 1000-gallon propane tank, you need to know **how big is a 1000-gallon propane tank**. That includes *length*, *diameter* (width), *total height* (with different domes on top of the tank), *empty weight*, and so on. We are going to list all these horizontal 1000-gallon propane tank dimensions in order for you to adequately reserve space for a propane tank of this size.

Here is the deal:

Even before you install a propane tank, you need to know what size it is. That will give you an idea of how much area (1000-gallon propane tank footprint) is needed to place the propane tank next to your house, and if you actually have enough lawn area to place it there. You can choose between **aboveground** and **underground** 1000-gallon propane tanks; the dimensions are *the same*.

Luckily, the size of a 1000-gallon propane tank is **standardized**. That means that all 1000-gallon propane tanks have the same dimensions. The standardized dimensions are found in ASME *(The American Society Of Mechanical Engineers)* propane tank specification sheets.

These spec sheets are usually hard to find if you are not an engineer working in the area. That’s why we will list all the 1000-gallon propane tank specifications from the ASME specs sheet here:

## Dimensions Of 1000-Gallon Propane Tank

1000-gallon is one of the biggest standardized propane tanks (only 2,000-gallon is bigger). Here is the full list of relevant specifications as per the ASME specs sheet:

**Length:**(or 16 Feet). A standardized 1000-gallon propane tank is 16 feet long.*192 Inches***Diameter:**(or 3 Feet and 5 Inches). All 1000-gallon propane tanks are shaped like a torpedo (round). That’s why we also call them to torpedo propane tanks. The diameter of a 1000-gallon propane tank is 41 inches; that is very relevant for width but less relevant for total height (we will look at how domes add to the total height).*41 Inches***Width:**(or 3 Feet and 5 Inches). A 1000-gallon propane tank is 41 inches wide. This comes from the diameter.*41 Inches***Empty Weight:**An empty 1000-gallon propane tank weighs 1760 pounds.*1760 lbs.***Full Weight:**1000-gallon propane tank can hold 800 gallons of propane (not 1000-gallon; due to the 80% max. capacity safety rule). At a 77°F temperature, 1 gallon of propane weighs 4.11 lbs. That means we are adding 800 × 4.11 = 3288 lbs of propane when we are filling the tank to the empty weight of 1760 lbs. The full 1000-gallon propane tank thus weighs 5048 lbs.*5048 lbs.*- Shell Thickness: 0.238 Inches. The shell of a 1000-gallon propane tank is 0.236″ thick.
- Head Thickness: 0.202 Inches.
- Leg Width: 4 Inches.
- Leg Distance From Shell Edge: 15 Inches.
- Leg Distance From Center Of Leg: 121 Inches.
- Shell Width: 151 Inches.
**Height With AG Dome:**All propane tanks will have a dome on top of them; this adds to the total height. A 1000-gallon propane tank with an AG dome has a height of 50 inches. This is the minimum height of a 1000-gallon propane tank.*50 Inches.***Height With AD/UG Dome:***51 Inches.***Height With 18 Inch UG Dome:**We are adding this 18-inch UG dome to the diameter and legs; resulting in a 1000-gallon propane tank total height of 60 inches.*60 Inches.***Height With 24 Inch UG Dome:**Same reasoning as with 18-inch UG Dome.*66 Inches.*

This is the full list of standardized specifications for a 1000-gallon propane tank. Now you know what is the size of a 1000-gallon propane tank, as well as some additional information such as shell thickness, and total height with different domes. Hope this helps.
