How Long Is a Pickup Truck?
The length of a pickup truck varies by style and manufacturer, but a typical traditional pickup is about 17 feet long, according to GMC. Both cabs and boxes come in longer and shorter sizes.
A GMC truck with a standard cab but a long bed is more than 18 1/2 feet in total length. A truck with a double cab and a regular bed is slightly more than 19 feet long. If a pickup has a larger crew cab with a standard box, the vehicle is about 20 feet long. However, if the truck has a crew cab with a short box, the entire length is a little more than 19 feet.
