Platform limits at a glance
Every channel has its own character ceiling, and many have a shorter effective ceiling before truncation kicks in. The six platforms covered here are the ones social media managers and SEOs bump into most.
- Twitter / X — 280 characters. X Premium subscribers can post up to 25,000, but replies and quote-tweets from non-Premium accounts still max at 280, so writing past 280 makes your post inaccessible to most of your audience.
- LinkedIn post — 3,000 character hard cap, but the feed cuts off at ~210 characters with a “…see more” fold. If your hook is not in the first line, fewer people expand.
- LinkedIn headline — 220 characters for the headline under your name. Every character is searchable, so loading keywords here meaningfully affects profile discoverability.
- Meta title — 60 characters is the safe ceiling; Google truncates above roughly 55–60 on desktop and around 50 on mobile. Titles also pull in your brand suffix from the layout.
- Meta description — 160 characters. Google truncates SERP snippets at about 155–160 characters depending on the query. Descriptions do not directly influence ranking but do influence click-through.
- SMS — 160 characters fit in one GSM-7 message. Past that, messages split into 153-character concatenated segments — you pay per segment, and not every carrier reassembles cleanly.
Counts are raw character length (UTF-16 code units), which matches what every platform on this list actually enforces. Emojis, accented characters, and CJK characters all count as the platforms count them.
Frequently asked questions
What is the character limit on Twitter / X?
A standard tweet is capped at 280 characters. X Premium subscribers can post up to 25,000 characters, but anything over 280 is hidden behind a “Show more” fold, so 280 remains the effective display limit for most audiences.
How long can a LinkedIn post be?
The hard limit is 3,000 characters, but LinkedIn collapses posts around 210 characters in the feed with a “…see more” fold. For maximum engagement, put your hook in the first line and the rest after the break.
What is the ideal meta description length?
Keep meta descriptions under 155–160 characters. Google truncates longer descriptions in search results with an ellipsis. The exact cutoff varies slightly by device and query, but 155 is a safe target.
Do emojis count as one character?
This tool counts JavaScript string length, which matches what Twitter, LinkedIn, and most platforms display. Most emojis register as 2 code units; composite emojis (skin-tone modifiers, family emojis) count for 4–7. The counter here matches what platforms actually enforce.
