The average weight of a passenger bus can vary depending on its size and capacity, but weight typically ranges from 25,000 to 40,000 pounds. For example, a standard Greyhound bus weighs about 35,100 pounds, but when passengers and luggage are added, that number jumps to 44,000 to 48,000 pounds. A Greyhound bus measures about 45 feet in length and carries 60 or more people.
