500 Gallon Propane Tank dimensions
Maximum fill 80% (~400 gal propane).
| Spec | Value |
|---|---|
| Diameter | 37.5 in |
| Shell (cylinder) length | 97 in |
| Overall length incl. heads | ~108 in (9.0 ft) |
| Geometric capacity | 500 gal |
| Nominal rating | 500 gal water capacity |
| Liquid weight (at the 80% legal fill) | 1,696 lb of liquid propane |
| Empty tank weight | ~950–1,000 lb (typical published) |
Clearance rules (NFPA 58)
Above-ground propane vessels of 125–500 gallons water capacity must sit at least 10 feet from buildings and property lines; 1,000–2,000 gallon vessels need 25 feet (reducible to 10 ft only in a specific single-tank case). Containers under 125 gallons may sit adjacent to a building, but still need 5 feet from building openings and 10 feet from ignition sources. Underground tanks up to 2,000 gallons need 10 feet from buildings and property lines. These are the NFPA 58 national baselines per the Propane Education & Research Council — many states and municipalities are stricter, so confirm locally before siting a tank.
