Count your Facebook post — the limit is huge, but the feed cutoff is small.
Facebook is generous with length: a post can run up to 63,206 characters. The catch is the feed, which collapses anything past roughly the first few lines behind a “See more” link. Short, punchy posts almost always outperform long ones. Paste your text to track its length.
Below are Facebook's character limits across posts, comments and profile fields, with an example of tightening a post to fit the visible preview and answers to common questions.
| Field | Limit | Notes |
|---|---|---|
| Post | 63,206 characters | — |
| Feed preview | ~477 characters | Longer posts collapse behind a “See more” link. |
| Comment | 8,000 characters | — |
| Username (vanity URL) | 50 characters | — |
| Bio / intro | 101 characters | — |

Trimming a long update so the key message lands inside the visible preview.
Hi everyone, I just wanted to take a quick moment out of my day today to share some genuinely exciting news with all of you, because over the past several months we have been working incredibly hard behind the scenes on something that we truly believe is going to make a real and meaningful difference, and after a lot of late nights and a lot of coffee, I am finally and absolutely delighted to be able to tell you that we are officially opening the doors to our second location next month, and we would love nothing more than to see you all there for the big celebration.
Big news: we're opening our second location next month! 🎉 Months of hard work (and a lot of coffee) made it happen. Join us for the grand-opening celebration — details below. We'd love to see you there!
A Facebook post can be up to 63,206 characters — effectively unlimited for normal use. The practical limit is the feed, which collapses long posts behind a “See more” link.
Facebook typically shows around the first 477 characters (a few lines) before adding a “See more” link. Put your key message and any link before that point.
Short posts perform best. Organic business posts of roughly 100 to 250 characters tend to get the most engagement, even though the hard limit is far higher.
Comments can be up to 8,000 characters, which is far more than almost any comment needs.
The short bio / intro on a profile is limited to about 101 characters, so keep it concise.
