TYPEFACE: A family of fonts, usually with different weights and styles (bold, italic, thin, etc.).We are referring to the use of letters created by type designers, and the arrangements of those letters that have been established by them. TYPOGRAPHY: The art of using pre-designed letters.We sketch, erase, correct, add, repeatedly until we are happy with the letterform and the connections between them. In this case, we build the letters using as many strokes as necessary. LETTERING: The art of drawing letters.No matter the tools we use dip pen, flat pen, brush marker, regular brush, etc., we make a stroke for every essential part of the letter, sometimes a whole letter or word. CALLIGRAPHY: The art or writing letters.
I already went into detail on each difference in this post: The difference between lettering, Calligraphy, and Typography. As we go into the details of this post, is important to differentiate the terms that many times beginners use interchangeably, but that are VERY different.
