Definition
A Twitter/X Bio is a brief self-description that appears on your profile, limited to 160 characters. It's your opportunity to tell others about yourself, your interests, expertise, occupation, or whatever you choose to share. Many users include relevant hashtags, their location, professional titles, or affiliations in their bio. A well-crafted bio helps others understand who you are and can influence whether people choose to follow you. For brands and public figures, the bio is an important piece of branding that should clearly communicate their purpose or value proposition.
