# How to write an Instagram bio in 150 characters

Updated 2026-11-09

To write an Instagram bio, state who you are or what the brand does in under 150 characters. The Instagram Bio Generator on ToolSugar writes up to 10 ideas from your description and shows a count on each. A small model runs in your browser, so your text is not uploaded, and each run counts toward 5 free AI runs per rolling 24 hours.

## Write a bio in four steps

Give the tool facts about the profile and let it handle the wording.

1. Describe the person or brand in the Who or what is the profile for box.
2. Choose a Tone and set How many bios, from 1 to 10.
3. Press Write bios and wait for the on-device model.
4. Check the count under each bio, shorten any marked over 150, then press Copy.

## What fits in 150 characters

That is about one line of what you do, a short phrase for visitors to act on, and maybe one emoji. A full résumé or a mission statement will not fit. Put the most useful words first, since people skim a profile in a second.

## How the character count works

The tool counts symbols you can see, so an emoji counts as one. Instagram may count some characters differently, so paste the final bio into the app and check that it saves.

The model is asked to stay within 150 but can miss. A bio over the limit is flagged in red so you can trim it first.

## Pick a tone for your audience

A personal brand can run playful, while a clinic or a law firm usually reads better in a plain, professional voice. Generate a few of each and compare them side by side.

Read the bio aloud once. If a line sounds like an advert, cut it.

## Keep private details out

Nothing is uploaded, but leave out an address or phone number if you plan to paste the bio publicly. The small model can invent facts. Read each result and delete any claim you cannot back up.

## Questions

### Can I put a link in the bio text?

Add links in the profile's link field in the app. The bio ideas here are text only.

### Why does one bio show in red?

It is longer than 150 characters. Shorten it by hand, then check the count again by pasting it back into the Word Counter.

### Will it make up details about me?

It is told to use only what you wrote. Still, read each bio before you post it.
