How to use these bio templates
- Pick the platform you're writing for. Each template shows its limit and current length.
- Copy a template and replace every {placeholder} with your own details — product, topic, audience, link.
- Read it out loud. If it sounds like a list of buzzwords, cut until it sounds like something you'd say.
- Paste it into your profile and check the platform's own counter before saving.

How do you write a good bio?
A bio has one job: help a stranger decide in a couple of seconds whether to follow or click. The templates above follow the same pattern — who you are, what you share, and where to go next.
- Lead with the topic, not the title."Easy weeknight vegetarian recipes" tells people what they'll get. "Food lover and dreamer" doesn't.
- Be specific about the audience."For first-time founders" filters in the right people and makes the bio feel written for them.
- Add proof if you have it.A number, a notable client, or a result ("Helped 200 cafés fill Tuesdays") does more than an adjective.
- End with one call to action. Point to your link, your newsletter, or your latest video. One clear next step beats three.
- Use keywords where search looks.Instagram and TikTok search your name and username fields, so a keyword there ("Sam | Bookkeeper") helps people find you.
Bio examples by platform
Instagram and Threads
150 characters and one clickable link area. Line breaks help: topic on the first line, proof on the second, call to action last.
TikTok
80 characters is roughly one short sentence. State your topic and posting rhythm, then rely on your link and pinned videos.
X and Bluesky
More room, and personality reads well here. Mention what you post about so people know what they're signing up for.
The headline shows next to every comment you leave, so treat it as your one-line pitch: role, who you help, and the outcome. Save the story for the About section.
Writing captions too? Try the caption templates or check post length with the character counter.
