How to Write a Threads Bio That Turns Visitors Into Followers

Most people reach your profile from somewhere else: a reply of yours under a popular post, a repost, a recommendation. They already liked one thing you wrote. The bio answers the next question: will there be more of that?

A useful bio therefore answers three things, in this order of importance: what you post about, who it is for, and why a stranger should believe you. You rarely fit all three; two is enough.

Take an invented physiotherapist, Lena, who posts about running injuries.

Draft 1: "Physio | Runner | Helping people move better" (44 characters). It describes a job and a hobby. Every physiotherapist could use it, so it tells a visitor nothing about this account.

Draft 2: "Physio for runners | Helping you avoid injuries" (47 characters). Better: the audience is named. But "helping you avoid injuries" is still a slogan, not a promise anyone can check.

Draft 3: "Physio for recreational runners | one injury explained per week: what it is, what helps, what doesn't" (101 characters). Now there is a content promise. A runner can scroll down and see whether the weekly post exists.

Draft 4: "Sports physio, 12 yrs | for recreational runners | one injury a week: what it is, what helps, what's a myth" (107 characters). The credential is short and real, the audience is clear, and "what's a myth" hints at the angle that sets her apart. This is the version she keeps.

If you created your Threads profile with your Instagram account, your username is shared, but your Threads bio, profile picture and link are your own. Meta's Help Center says changing them on Threads does not change them on Instagram. That is useful: your Instagram bio may be written for a visual portfolio, while your Threads bio can describe what you write about.

Meta does not state a character limit for Threads bios in its Help Center; Instagram's is 150 characters. Writing to roughly that length is a sensible target anyway, because a bio someone reads in a few seconds should not be longer.

The bio works together with a few other elements. Each of them is worth a few minutes.

Listing everything you are ("Founder | Mom | Runner | Coffee addict | Dreamer") leaves a visitor with no idea what you post. Using adjectives instead of facts ("passionate", "results-driven") costs space and proves nothing. And writing a bio for the account you hope to have, rather than the one a visitor sees today, creates a gap the first few posts will expose.
