In 2019 Packt claimed it had published 6,500 books over its 16 years of operation. Packt offers printed version of their books shipped to Europe, North America and selected Asian countries.

Packt Enterprise focuses on technologies produced by businesses for use in other corporations, while Packt Open Source focuses on technologies built around open source licences.
