The average size of a suitcase is 28 inches by 32 inches. Airlines restrict the size of a suitcase that can be carried on the airplane and the size that can be in the cargo hold. Usually, a bag that is 16 inches by 20 inches is the largest carry-on bag. The cargo hold cannot hold a suitcase that is larger than 63 inches long.
