Social Media Character Limits (2026)
Updated 2026-07-04 · By the MakeToolz team
Quick answer: The main 2026 character limits are X posts 280, Instagram captions 2,200 (bio 150), TikTok captions 2,200, YouTube titles 100, and LinkedIn posts 3,000. Check any caption against all of them at once with a social media character counter.
Each platform sets its own cap, and going over it means your text gets cut off or the post is blocked. The bigger trap is the "visible" limit, the shorter window a feed actually shows before hiding the rest behind a "more" link. Both matter, and they are not the same number.
The full limits at a glance
- X / Twitter post: 280 characters for standard accounts. Paid Premium accounts can post much longer.
- Instagram caption: 2,200 characters. Bio: 150. Comment: 2,200.
- TikTok caption: 2,200 characters. Bio: 80.
- Threads post: 500 characters.
- YouTube title: 100 characters. Description: 5,000.
- YouTube Community post: up to about 3,000 characters.
- LinkedIn post: 3,000 characters. Headline: 220. About section: 2,600.
- Facebook post: 63,206 characters, though almost no one comes close.
- Pinterest description: 500 characters. Pin title: 100.
- Bluesky post: 300 characters.
These caps hold across the web and the mobile apps. Where a platform charges for a longer limit, like X Premium, the free tier is the number most people should write to.
Why the limits matter
Go over a limit and the platform either trims your text or refuses to publish. That is the obvious problem. The quieter problem is that hitting the cap is rarely the goal. A 2,200 character Instagram caption is legal, but almost no one reads to the end. Most feeds reward a tight, front-loaded message far more than a long one.
Search and discovery also lean on the opening characters. A YouTube title that puts the keyword first ranks and reads better than one that buries it at character 90. So think of the limit as a fence, not a target. Say the important thing early and stop when the point is made.
The hidden "visible" limits
The hard cap is only half the story. Each platform shows a shorter preview in the feed before it hides the rest:
- Instagram shows roughly the first 125 characters of a caption before the "more" link. Put your hook there.
- X shows the whole 280, but the first line is what stops the scroll, so lead with it.
- YouTube titles get truncated in search results around 60 characters even though the cap is 100. Keep the key words up front.
- LinkedIn collapses a post after about 3 lines, near 210 characters on desktop, before the "see more" link.
- TikTok shows only a line or two over the video, so the first few words carry the caption.
Write the hook first, then the detail. If your message lands in that opening window, the full cap almost never matters.
How emoji, links, and mentions count
Not every character weighs the same. A plain letter is one character, but other elements behave differently depending on the platform:
- Emoji often count as one or two characters, and some complex emoji (like flags or skin-tone variants) count as more behind the scenes because they are built from several code points.
- Links on X are shortened to a fixed length by the platform, so a long URL does not eat your whole budget. Other platforms count the full link.
- @mentions and #hashtags count every character including the symbol.
- Line breaks count as characters too, which can quietly push a tight caption over the edge.
Because the counting rules differ, eyeballing the length is a guess. A counter that mirrors each platform's rules gives you the real number.
Check before you post
Guessing wastes time and risks a cut-off caption. Paste your text into the free Social Media Character Counter and it shows, live, whether your caption fits every platform at once, with the exact characters you have left for each. You can trim a tweet to 280 or confirm a LinkedIn post clears 3,000 without switching between apps.
People Also Ask
What is the character limit for a tweet in 2026?
A standard X post is still 280 characters. Paid X Premium accounts can write far longer posts, up to tens of thousands of characters, but 280 is the safe target for regular accounts and for anything meant to be quotable.
What is the Instagram caption character limit?
2,200 characters for a caption and 150 for your bio. Only about the first 125 characters appear in the feed before the "more" link, so lead with the part you most want people to read.
Do emoji count as one character on social media?
Usually one or two, but some complex emoji count as more because they are made of several underlying code points. A skin-tone or flag emoji can quietly use several characters. A character counter shows the true total so a caption does not surprise you at the cap.
Why does my caption get cut off even when it fits the limit?
Because the visible preview is shorter than the hard cap. Instagram hides text after about 125 characters, LinkedIn after a few lines, and TikTok after a line or two. Your caption fits, but the feed only previews the opening. Move the key message to the front to fix it.
What is the LinkedIn post character limit?
3,000 characters for a feed post. Your headline caps at 220 characters and the About section at 2,600. The feed collapses a post after roughly three lines, so the first sentence has to earn the click on "see more".
Is the character limit the same on mobile and desktop?
Yes. The hard caps are set by the platform and do not change between the app and the website. What can differ is the visible preview length, since a narrow phone screen shows fewer characters before truncating than a wide desktop feed.
How long can a YouTube title and description be?
A YouTube title caps at 100 characters and the description at 5,000. Search results usually cut the title around 60 characters, so put your main keyword and hook in the first 60 to keep them visible.
What happens if I go over a platform's character limit?
The platform either blocks the post until you trim it or silently cuts the extra text. On X you cannot publish past 280 on a free account. On caption fields, overflow is often just chopped off, which can leave your message ending mid-sentence.
Before you hit post, run your text through the free Social Media Character Counter to see it measured against every platform live, so your caption fits and your hook lands before the cutoff.
