Serif vs. Sans-Serif — Anatomy and Use
A serif is a small decorative stroke at the end of a letterform's main strokes. Times New Roman, Georgia, and Garamond are classic serifs — their foot-like terminals guide the eye along a line of text, making long-form reading in print more comfortable. Research consistently shows serif fonts aid reading speed in printed body text of 10–14 pt. Sans-serif typefaces (Helvetica, Arial, Inter, Futura) lack these terminals, producing clean, geometric letterforms that render crisply on low-resolution screens. This is why virtually all mobile apps, websites, and user interfaces use sans-serif fonts for body text. Beyond serifs and sans-serifs, other categories include slab serifs (Rockwell, Clarendon — chunky terminals for impactful headlines), script fonts (mimicking handwriting — use sparingly and never in all caps), and display fonts (highly stylized, for headlines only). Learning to identify type anatomy — baseline, cap height, x-height, ascender, descender, counter, bowl — gives you precise vocabulary to discuss and evaluate type choices.
