Facebook Character Counter — 63,206

Our free Facebook Character Counter covers every character limit across the entire Facebook ecosystem — from organic posts and comments to paid ad copy — all updating in real time as you type. Facebook posts technically support up to 63,206 characters, making it the most generous text limit of any major social platform. But research consistently shows that posts between 40 and 80 characters receive the highest engagement rates — our counter helps you hit that sweet spot every time.

For Facebook advertisers, our counter is essential. Ad headlines are hard-capped at 40 characters — the length Facebook displays without truncation in News Feed placements. Primary ad text shows only 125 characters before a "See more" prompt appears. Going over these limits doesn't prevent your ad from running, but it does reduce the impact of your copy. Our counter tracks the headline (40 chars), primary text (125 chars), ad description (30 chars), and all organic fields — post (63,206), comment (8,000), page name (75), group name (75), and event title (64) — in a single view.

Whether you're a social media manager crafting organic posts, a performance marketer writing ad copy, or a small business owner managing your own page, our Facebook Character Counter removes the guesswork from every character decision. Paste your text above, watch the live count, and write Facebook content that fits perfectly — before you ever open the platform.
