Why is graffiti usually done with bubbly letters?
Most graffiti is done in bubbly letters because this is the easiest lettering to draw and translate into painting [1]. The initial aim of the game was to become infamous from painting your name in as many places as possible visible to as much of the wider city as possible [1]. The first transition of this is what we commonly call a throw up [1]. Throw ups are the graffiti Bubble letters or abbreviations of a graffiti writer's tag [1]. These letters are usually bubble letters that are filled in with another color [2]. The reason why they are popular has to do with how long this method has been around [1]. It is instantly recognizable as graffiti, and it is the easiest to draw and translate into painting [1, 2].
The reason for the popularity of "bubble letters" in graffiti comes from the fact that they are easy to read and do not have too many stylistic flourishes [1, 2]. Additionally, because the letters are fat with a differently-colored outline, they take on a rounded shape, which allows for quick formation [3]. This is known as a "throwup" style of graffiti [2, 3]. A more complex style of graffiti is "wildstyle," which is a form of graffiti involving interlocking letters, arrows, and connecting points [4]. This form of graffiti is very hard to read by people who are not familiar with it due to the complexity and numerous layers and shapes involved [4]. It is an original style in graffiti that is seen as one of the greatest artistic challenges to a graffiti writer [4].
