How Tall Is a Typical Semi Truck?

Semi-trucks, also known as semi-trailers, are large trucks designed to transport goods across long distances. They are an essential part of the global economy, transporting goods from factories to stores and businesses. Semi-trucks come in many different sizes and configurations, so it can be difficult to determine a “typical” height for them. However, there are some general guidelines that can be used to measure the average height of a semi-truck.

The average height of a semi-truck is between 13 and 15 feet tall. This includes the cab, which is typically two or three feet tall, as well as the trailer, which can range from 10 to 12 feet tall depending on its size and design. The overall length of a typical semi-truck is around 53 feet long.

In addition to their overall height, semi-trucks also have specific clearance heights that must be considered when traveling through low tunnels or bridges.

The Federal Highway Administration (FHWA) regulates these clearance heights in order to ensure that all semi-trucks comply with safety standards. The FHWA requires that all trucks have at least 13 feet 6 inches of clearance when traveling through tunnels or bridges.

Semi-trucks come in many different sizes and designs depending on their purpose and intended use. Some may be shorter or taller than the average 13 – 15 foot range depending on their specifications. For example, dump trucks usually have higher trailers than other types of semi-trucks in order to accommodate their cargo capacity.


So how tall is a typical semi truck? On average, a semi truck stands between 13 – 15 feet tall including the cab and trailer. However, this measurement is dependent on the type and design of the truck so some may be taller or shorter than this range depending on their specifications.
