How to Write an X Bio That Works

Your bio has one job: help a stranger decide in a couple of seconds whether to follow you. They usually arrive from a reply or a repost, glance at your name, read the bio, and decide. X gives you 160 characters for that, about the length of two short sentences.

That limit is generous if you know what to cut. Most weak bios are weak because they try to say everything. Below is the method we used to write the 320 templates in our bio library, and it works whether you start from a template or from scratch.

Start with what people will get

Lead with what you post about or what you do, in the words your future followers would use. "ER nurse in Cleveland" tells a reader more than "Healer. Dreamer. Coffee addict." The first one also turns up when someone searches X for nurses in Cleveland. The second turns up for nobody.

A useful test is to read your first five words on their own. If those five words give someone a reason to follow, the rest of the bio is a bonus. If they could describe ten million other people, rewrite them.

Some first lines that pass the test:

"Middle school science teacher."
"Speedrunning Hollow Knight on PC."
"Recipe developer, mostly Korean home cooking."
"Backend engineer working on payments."

None of them is clever. All of them are specific.

Add one detail that is yours

After the opening, add one thing that makes you a person and not a job title. It can be a hobby, an opinion, a running joke or a small fact. "Night shift, strong coffee, stronger opinions about hand hygiene" does more work than a list of five hobbies because it has a voice.

One detail is usually enough. Two can work if the bio is short. By the third, people stop reading. If you find yourself writing "lover of X, Y and Z", pick the one you would most like to talk about and drop the others.

Leave the other fields to do their jobs

X gives you separate fields for location and a website, and neither of them uses bio characters. Your display name sits above the bio. That means a lot of what people cram into bios is already covered:

Your city can go in the location field, which holds up to 30 characters.
Your main link belongs in the website field. A link pasted into the bio uses every one of its characters.
Your name is already at the top of the profile. Repeating it in the bio wastes space.

The exception is when a detail matters enough to say twice. A local reporter might put the city in both places because it is the core of the account. That is a choice, though, and most people should not default to it.

Write for search, not for keywords

People do search X for accounts, and the bio is one of the things search looks at. That doesn't mean stuffing it with terms. It means using the plain nouns people would type. "Photographer" beats "visual storyteller". "Python" beats "code wizard".

Hashtags are rarely worth it in a bio. One hashtag for a real community (#NursesOfX, #WritingCommunity) can help people in that community find you. Three or more starts to look like spam, and the writer on our home page flags it for that reason.

Use emoji with a light hand

Emoji can add color, and a single one can stand in for a whole phrase: a microphone for a podcaster, a plant for a gardener. They have two costs you should know about.

The first is accessibility. Screen readers read each emoji by its name, so "🎮🎧☕🐶" becomes "video game, headphone, hot beverage, dog face" for anyone listening to your profile.

The second is the character count. A simple emoji usually counts as one character, but many emoji are built from several pieces joined together. Flags, skin-tone variants and family emoji can count as several characters each, even though they look like one. If your bio is close to 160, that matters. Our writer shows both numbers when they differ.

Two or three emoji in a bio is plenty. In a display name, one is usually the most that still leaves your actual name readable in replies.

Pronouns, credentials and disclaimers

X doesn't currently offer a separate pronouns field, so people who want to share pronouns put them in the display name, in parentheses, or at the start or end of the bio. Write them with a slash and no spaces (she/her, they/them), because that is the format most readers expect. Choose one place and don't repeat them.

Credentials work the same way. "RN", "MD", "PE" or "PhD candidate" are short and carry weight. Put the ones that matter for what you post and skip the rest.

Some professions need a disclaimer. Doctors, nurses, lawyers and therapists often add "not medical advice" or "not legal advice", and many employers ask staff to say that their views are their own. Those lines cost 15 to 25 characters, so plan for them from the start.

Cut, then cut again

Write a first draft without counting. Then cut it to 160, and then try to cut 20 more. Bios almost always read better shorter. Things that can usually go:

Filler words like "just", "passionate about" and "lover of all things".
Lists longer than two items.
Anything already in another field.
Stacked labels separated by pipes, if there are more than three.

A before and after shows how much the cutting helps. Before: "Passionate educator and lifelong learner who loves all things science, coffee, hiking and spending time with my family and dogs! Views are my own." After: "Middle school science teacher. Sharing labs that work on a $50 budget. Hiking on weekends, coffee always."

The second version is shorter, more specific, and gives a reason to follow: cheap labs.

Check it on a phone

Most people will see your bio on a phone, where it wraps differently than on a desktop. Line breaks, long words and runs of emoji can look odd in a narrow column. A long display name gets cut off in replies, so the first 20 or so characters of your name are what most people will actually see.

Our writer shows a phone-width preview and a reply view so you can catch those problems before you save. It is an approximation, since X's own layout varies by app and screen size, but it catches the common issues.

Revisit it when things change

A bio is easy to forget. The most common problem we see is a bio that was accurate two years ago: a student who graduated, a job that ended, a book that came out and was never mentioned. Read your bio whenever something big changes, and at least once a year even if nothing has.

When you do rewrite it, look at your pinned post at the same time. The two are read together, and they work best when they tell the same story.

Questions

What should I put in my X bio?

Start with what you do or what you post about, add one detail that is specific to you, and stop. Your location and website have their own fields, so they don't need to be in the bio.

Should I use hashtags in my bio?

One or two at most, and only for communities people actually browse. Plain words work for search, and a bio full of hashtags tends to look like spam.

How often should I update my bio?

Whenever something in it stops being true: a new job, a finished degree, a launched book. Many people also refresh it once or twice a year so it matches what they post now.
