The weight of a phone book varies depending on its size, location, and age. An average traditional hardcopy telephone directory weighs around 1.2 to 1.6 kilograms ( 2.65 to 3.5 pounds). Phone books from larger cities will be heavier due to the increased number of listings.
With the widespread adoption of digital communication and online phone directories, the traditional hardcopy phone book has become less prevalent. Some communities or regions may still publish phone books, but their circulation has significantly decreased.
