What Size Is a Semi Truck Door?

Semi-trucks, also known as semi-trailer trucks, tractor trailers, big rigs, and 18-wheelers, are a common sight on major highways and interstates throughout the United States. Semi-trucks move goods over long distances, as well as provide services to local businesses.

Like other vehicles, semi-trucks have doors that provide access to the cab. But what size are these doors?

The size of a semi-truck door can vary depending on the make and model of the truck. Generally speaking, the standard door size for semi-trucks is 48 inches wide by 80 inches tall. This is slightly larger than a standard residential doorway or a commercial building entry door.

Some semi-trucks may have doors that are slightly larger or smaller than the standard size. For example, some newer models from specific manufacturers may have wider and taller doors than the traditional sizes. Additionally, some older models may have smaller or shorter doors.

The width of semi-truck doors also depends on whether they open outward or inward. Doors that open outward need more space in order to open all the way without hitting anything around them. Therefore, outward opening doors are typically wider than inward opening doors.

In conclusion, semi-truck doors come in different sizes depending on the make and model of the truck and whether they open outward or inward. Generally speaking, though, most semi-truck doors measure 48 inches wide by 80 inches tall.
