Bold text where there is no bold button
Instagram, Facebook posts, LinkedIn and YouTube comments do not have a bold button. These styles replace each letter with a bold character from the Unicode Mathematical Alphanumeric Symbols block, so the weight comes with the text. Bold sans looks like most app fonts and blends in best; bold serif looks more classic.
Our honest take: bold sans almost always beats bold serif on social media, because it matches the app's own font and stops looking like a gimmick.
Use bold sparingly
Bold works best for a word or a short line you want people to notice, like a headline at the top of a post. Screen readers may read each bold letter by its math name, so keep key details such as dates and links in normal text. For slanted text, see italic text.
How it looks in your apps
Same text, three apps.
