Each typewriter has its own design. The 2 most popular categories of typewriters are:
♦ STANDARD (large office models) and
♦ PORTABLE (small models, usually with suitcase).
There are also older models of non-standard typewriters, such as index ones. If you look at typewriters, you will discover the inventive design of each brand. Over time, you will be able to find out what type of typewriter suits your personal needs.
