Social Media Character Counter

Character limits on every major platform

Every platform counts a little differently, and most of them cut your post off long before the hard limit. The numbers below are the maximums; the practical limits in the next section matter more for how your post actually reads in the feed.

The limit that actually matters is the truncation point

Hitting the maximum is rarely your problem. Getting cut off mid-sentence is. Whatever comes after the cut is only read by people who already decided to tap:

• Instagram: hides everything after roughly 125 characters behind “more”.
• LinkedIn: truncates at about 210 characters on desktop, closer to 140 on mobile.
• Facebook: clips at around 480 characters.

Treat the first line as the whole pitch

Put the hook, the number, or the question up front. Let the detail live below the fold.

A 3,000-character LinkedIn post is fine, as long as the first 210 characters earn the click.

What counts as a character

• Spaces and line breaks count on every platform.
• Emoji usually count as two characters, not one, because of how they're encoded.
• Hashtags and @mentions count toward the limit like any other text.
• On Twitter/X, links are always counted as 23 characters no matter how long the URL is.

How to use the character counter

1. Paste or type your post into the box.
2. Pick the platform you're writing for.
3. Watch the counter against both the hard limit and the truncation point.
4. Trim until your hook lands before the cut-off, not just under the maximum.
