The headline of a page must be distinctive and clearly recognizable as such. It should be dominant, and no other element on the same page should compete against it too strongly.

The headline can express very diverse statements., but there should never be two statements in one headline, because the reader might get confused.

Moreover, the main title should be legible, because it is a page's dominating typographic element. If it isn't, it misses its purpose to spark the reader's interest.

 

How many lines should / may a headline consist of?:

Generally, a headline should be as short and meaningful as possible. It may be up to 2 lines long; headlines that take up 3 or 4 lines often seem overloaded.

If a title is relatively long, it may be helpful to use a font with narrow tracking (character spacing).

 

Separations:

In a headline, word separations are frowned upon. They are unaesthetic and make a title less ascertainable.

 

In narrow columns, if it is unavoidable, you may need to separate words, but you should always pay attention to make sensible separations.

Bei schmalen Spalen, wenn es gar nicht anders geht, kann getrennt werden, man sollte dabei aber auf sinnige Trennungen achten.
