What makes a good X bio
A bio has one job: help the right stranger decide to follow you after a single glance. The strongest bios answer four questions in that order.
- Who you help. Name the people you serve or the problem you work on. "Helping bookshops manage stock" beats a list of job titles.
- Proof. One concrete fact that earns trust: customers served, years in the field, something you shipped.
- What you post. Tell people what they get by following, so the follow feels like a fair trade.
- A next step. A link, a product, a newsletter or "DMs open for [topic]". Give the curious reader somewhere to go.
You rarely fit all four in 160 characters. Pick the two or three that matter most for your goal, and let your pinned post and header image carry the rest.
A universal bio formula
[What you do] for [who]. [One proof point]. Posting about [topic 1] and [topic 2]. [Next step]
Filled in: "Stock software for independent bookshops. Used in 400 stores. Posting about retail and running a small team. Try it free below." That is 129 characters, leaving room for a small personal touch.
Browse by niche
Each niche page explains what a strong bio does for that audience, then gives 10 examples in different styles: proof-led, mission, humour, metrics, lists and more. Start with the founder bio examples, the developer bio examples or the creator bio examples, or pick your niche from the cards below.
Frequently asked questions
How long can an X bio be?
An X bio holds up to 160 characters. Your display name, location and website have their own limits, listed on the X profile limits page.
Should I use emoji in my X bio?
One or two emoji can add colour and break up a list, but they take space and can read as clutter. Use them where they replace words, such as a flag for location.
How often should I change my bio?
Update it when your work changes or you have a stronger proof point, such as a launch or a milestone. Many people review it every few months.
Can I copy one of these bios?
Yes, they are original examples written to be adapted. Swap in your own product, audience and proof so the bio sounds like you.
