On Type / Bold sans-serifs
Bold sans-serifs: Not just loud, but expressive
Bold sans-serif fonts aren’t just sans-serifs at heavy weight. The shift from light to bold reveals design choices that aren’t visible at smaller sizes: how the crossbar of an A sits, how the bowls of o, b, and d relate to the vertical stems, whether terminals soften or sharpen. The bold weight is where the typeface’s character lives.
This list covers the bold sans-serif fonts we use and recommend, from confident geometric forms to softer rounded shapes. Each entry includes a note on what makes the bold weight distinctive.
