Heinz managers were confident that the plastic bottle delivered significant consumer benefits, but they were not sure which size(s) was right. Should they start with an existing size or create a new size for plastic? The ketchup brand group planned a consumer-testing program of various package sizes, primarily 64 oz. and 28 oz. Johnson and her group started with the 64 oz. size (5 3/6 " wide x 4" deep x 10 3/4 " tall) because plastic's shatterproof and lightweight attributes would be most beneficial in a large size. The plastic 64 oz. container offered 20 ounces more ketchup than the 44 oz. glass bottle but, when full, both packages weighed the same. In addition, the category trend was toward larger sizes, as evidenced by the success of Heinz 44 oz. ketchup.
