Facebook Character Limit 2026 (63,206)

Facebook's post character limit is 63,206 characters, an oddly specific number that has stayed the same for years and still surprises people who assume it is closer to a tweet-length cap. In practice almost nobody writes a post anywhere near that long, but the number matters if you are pasting in a long update, a detailed announcement, or a repurposed blog excerpt.

How Many Characters Can a Facebook Post Be, Really

The honest answer to how many characters can a facebook post be depends on what you mean by "be." The hard technical ceiling is 63,206. The number that actually matters for most posts is the truncation point, since anything past roughly 477 characters on desktop, or around 125 on mobile, gets folded behind a "See More" link. Past that point, you are relying on the reader to tap through, which a meaningful share of scrollers simply will not do.

Why the Limit Barely Matters Day to Day

Facebook post character limit only becomes relevant in a few specific situations:

• Long-form announcements, like a company update or a detailed policy change, where you genuinely need the space.
• Pasted content, when you are copying in text from an email, article, or press release without editing it down first.
• Event descriptions or notes-style posts, which lean into Facebook's longer-form roots more than a typical feed post does.

For a normal feed post trying to drive engagement, writing well under the "See More" truncation point is the more useful target than the 63,206 ceiling. Posts under roughly 80 characters have shown notably higher engagement in recent benchmark data, so short and punchy still tends to outperform long on Facebook's feed specifically.

Writing to the Truncation Point on Purpose

If you do want to write longer, structure it so the value is front-loaded. Put the point, the offer, or the hook in the first two sentences, before the truncation point hits, and treat everything after "See More" as detail for people who are already interested rather than the main pitch.

A character counter makes this easy to check before you post, so you know exactly how much of your caption shows before the fold without guessing.

Keeping Facebook Posts Consistent

Whatever length you land on, posting it at a consistent time matters more for reach than shaving a few characters off a caption. Posted Once schedules your Facebook posts alongside every other platform you run, so length and timing both stay intentional instead of an afterthought. Start free →

63,206 is the number worth knowing, but 477 is the number worth writing to.
