Well observed. There are a myriad of influences in Inter, some from existing fonts, some from graphic design and shapes I’ve seen in my surroundings and some ideas that grew out of thoughts. For instance, the bend of the “t”, “f” et al just felt right and was not influenced by anything else but their own shapes. In contrast, the “a” was inspired by many existing typefaces like Akzidenz Grotesk, Helvetica, etc. The shapes of the glyphs, spacing and angles of Inter have gone through a long evolution during the past three years. For instance, “e”, “1”, “s”, “g”, “n”, “m”, “d” (and several others) changed a lot early on.
