The most prominent feature of Septimus is its elegant, flowing serifs, which are the small decorative strokes at the ends of a letter's main stems. Unlike the blocky, geometric serifs found on a font like Rockwell, Septimus's serifs are curved and organic, giving the text a sense of sophistication and fluidity. Complementing these serifs is a noticeable contrast in stroke thickness. This means the vertical strokes of letters like "H" are thick and robust, while the horizontal strokes are notably thinner. This high-contrast stroke variation is a hallmark of classic, elegant serif designs and is a key factor in its legibility. As one review noted, "With satisfyingly thick verticals it offers good, clean legibility," making it an excellent choice for refined typography.

Because of its unique personality, the Septimus font is best suited for applications where text needs to be more than just read—it needs to be seen.
