Every Facebook limit, with its source
Facebook’s help center covers its name rules, the 60-day name change and group post formatting. Post, comment, Intro and Page name lengths are third-party figures and are labeled that way.
| Field | Limit | Details | Styled text | Source |
|---|---|---|---|---|
| Profile name | No symbols or mixed scripts | Facebook does not allow symbols, numbers, unusual capitalization, repeating characters, punctuation, or characters from multiple languages in names. Styled letters are Unicode symbols, so expect them to be rejected. | No | Official |
| Name changes | Once every 60 days | Only change your name when it is final. | — | Official |
| Post | 63,206 characters | Long posts collapse behind “See more” long before this. | Yes (Unicode) | Third-party |
| Comment | 8,000 characters | Per comment. | Yes (Unicode) | Third-party |
| Intro (profile bio) | 101 characters | The short line shown under your name on your profile. | Yes (Unicode) | Third-party |
| Page name | 75 characters | Keep business Page names in plain letters so people can search for them. | — | Third-party |
| Group post formatting | Bold, italics, headers, quotes, lists | Facebook has real formatting buttons in group posts, on a computer only. Ordinary posts and comments have no formatting buttons, which is why people paste Unicode bold there. | — | Official |
| Hashtags | No number published | Meta says accounts posting long, distracting captions “often with an inordinate amount of hashtags” are shown only to followers and lose monetization. | — | Official |
Last checked: 9 October 2026. “Official” means the platform’s own help center or newsroom; “Third-party” figures come from reference sites and are not published by the platform; “Reports” are user and practitioner observations.
The Intro is short: about 101 characters
The Intro, the bio line under your name, holds about 101 characters by third-party counts. That is room for one sentence, so pick what you most want a stranger to know and leave the rest to your posts.
Styled letters work in the Intro. One bold or italic phrase reads better than a fully styled line; the Facebook font generator counts against 101 as you type.
Names have rules, not a character count
Facebook’s help center lists what names cannot contain: symbols, numbers, unusual capitalization, repeating characters or punctuation, characters from multiple languages, titles, and words or phrases instead of a name. Bold or script letters are Unicode symbols, so they fall under the first rule.
You can change your name every 60 days, so a rejected or regretted name can take two months to fix.
Group posts have real formatting
In a Facebook group, on a computer, you can highlight text in a post and apply bold, italics, headers, quotations and lists. Facebook’s help center says this built-in formatting is available on computer only. Everywhere else, including the app, bold comes from pasted Unicode characters.
