Facebook Bio and About Length Guide 2026

Facebook does not use one single "bio" field the way Instagram or X does. A personal profile's Intro line runs about 101 characters, while a Facebook Page's short description field allows up to 255 characters, and Pages also have a separate, longer About section for more detail. Which limit applies to you depends on whether you are editing a personal profile or a business Page.

Personal profile: the Intro line

On a personal profile, the short line that appears under your name and photo (your "Intro") is capped at roughly 101 characters. That is tight, closer to a tagline than a bio, so most people use it for a single clear detail: a job title, a location, or one sentence about who they are. There is no long freeform "about me" bio field on a personal profile the way there is on Instagram or Threads.

Facebook Page: short description vs. About section

Pages get more room, split across two fields:

• Short description: up to 255 characters, shown in Page previews and search results. This is the field that functions closest to a "bio."
• About / Story section: a longer freeform field for your full business description, history, and details, with far more room than the short description.

For businesses, the short description is what most people see first, so treat it like the 255 character version of an elevator pitch, then use the longer About section for detail that will not fit anywhere else.

How long can a facebook bio be, in one line

• Personal profile Intro: ~101 characters
• Page short description: 255 characters
• Page About / Story section: long form, no tight practical cap

Where the confusion usually comes from

Most "Facebook bio character limit" questions actually come from people managing a Page who assume it works like a personal profile's Intro, or vice versa. If you are setting up a new Page, go to Page Settings, then Page Info, to find the short description field separately from the longer About section, rather than looking for a single "bio" field the way Instagram's edit profile screen presents it. Personal profiles do not have an equivalent longer field at all, so anyone wanting more space for a detailed bio needs to either switch to a Page or lean on the About section of their personal profile, which allows longer entries for work history, education, and other structured details, just not a single freeform paragraph field.

Writing to the limit

Since the personal Intro and Page short description both cut off quickly, lead with the most important word or phrase rather than a greeting or filler ("Freelance photographer, Austin" beats "Hi! I'm a photographer based out of Austin, Texas"). Check your exact character count with the Facebook character counter before you save changes, since Facebook's editor does not always show a live count as you type.
