iMovie and garageBand are larger apps and also have a large library of additional helper files (Sound Loops, etc.). If you remove them from this list, because they are only downloaded if you need them, and can be deleted after setup on a new Mac, the remaining iWork apps take up very little space. It still confuses me how people will complain about the cost of a Mac, which lasts longer than a Windows PC, gives you free OS upgrades for years, and free apps and upgrades that provide all the functionality of Business Office (Word Processor, Page Layout, Spreadsheet, Presentation, Mail, AddressBook, Calendar, Notes, To Do lists (Reminders), etc., then think nothing of spending money on Microsoft, even though there is no need, its features change, and you either have to keep buying it or subscribe annually. 17 years I have gone without buying a copy of office (even though one was given to me I never used), and have had no problems with compatibility or features needed.
