Brief ideas about typeface

Sans Serif
Univers, Helvetica, Futura...
 They have sound readability.

Script
I find it difficult to use as they have a relatively lower readability. It will probably be used as in the headline or on the background. Also, it is fit when the content is about youth, artists or activity (anything positive).

Serif
I find it hard to use traditional serif typeface actually. It can be used it as in the reference of a booklet or as in the body text in the most of the times. Slab is better as it has a higher readibility.

Inline&Stencil
It is a kind of text that have a decent readability but still remain interesting. It is useful as on the headline.

Pixel font
Depending on the case.

Black letter
According to the case.
