I'd like to find similar fonts to Bebas (below):
What do you call these types of fonts? Thick, tall, and usually all in uppercase?
If you're searching for fonts like that, look for condensed fonts. Traditionally used for cramming words into small spaces, they're more often used now for crisp bold blocky titles. Here's an article about using them well.
Tall font = narrow font, set at a large size.
Most font browsers will let you search on 'condensed' as a search term, and narrow by sans and weight using facets - some, like Typekit, will even let you put in 'Width', including narrow fonts that don't identify as condensed - https://typekit.com/fonts?classification=sans-serif&weight=heavy&width=condensed.
I don't think they have a particular name.
I would probably call them Black, Heavy or Extra Bold fonts.
Typekit has a nice search tool that lets you browse by style (in this case sans-serif) and weight, among other properties.
Bebas is a "condensed" "sans serif" font. Some font families have condensed versions, meaning that the width of the letters is narrower in the condensed version than in the block or book versions. Serifs are the little flourishes coming out of the character where it sits on the baseline like Times New Roman or Garamond. Sans is french for without, so sans serif simply means without serifs.
As you can see in this example, Helvetica narrow bold closely resembles Bebas:
Helvetica is a sans serif font. So by selecting a condensed and bold version, you adequately replicate BEBAS.
