The ultra-portable typewriter was intended for travelers. Particularly air, train travel.
These were never intended to write “the Great American Novel” on them. They were for letter writing while traveling, for traveling salesmen to fill out their order cards and reports, journalists on the go, and government types who needed to file reports while traveling.
Like any machine they can be pressed into writing longer works but they are not optimal.
Seems like most have basket carriage which is not optimal for lots of quotation marks and caps shifting like one would have with dialog.
Size Smallest to Larger:
