Character Limits for Every Social Platform (2026)

The maximum length of a post or caption on each platform:

• X (Twitter): 280 characters for free accounts. X Premium subscribers can write long posts of up to 25,000 characters. Every link counts as 23 characters.
• Instagram: 2,200 characters per caption, with about 125 visible before the more link.
• TikTok: up to 4,000 characters when posting in the app, or 2,200 through most scheduling tools. Only about the first 100 show in the feed.
• LinkedIn: 3,000 characters per post, with roughly the first 210 shown before see more.
• Facebook: over 60,000 characters, but only about the first 470 show before see more.
• Threads: 500 characters.
• Bluesky: 300 characters.
• Mastodon: 500 characters on most servers, though some servers allow more.

Shorter fields that are easy to overrun:

• Instagram bio: 150 characters.
• X bio: 160 characters.
• LinkedIn headline: 220 characters.
• YouTube video title: 100 characters, and 5,000 for the description.
• Pinterest Pin title: 100 characters, and 500 for the description.

Two limits that matter outside social media:

• Google page titles: about 60 characters before they are cut off in search results. The real limit is a pixel width, so wide letters run out sooner.
• Meta descriptions: about 150 to 160 characters.
• SMS text messages: 160 characters per message, or 70 when the message contains an emoji or other special characters. Longer texts are split into several messages.

The hard limit rarely matters. What decides whether people engage is the first line before the feed cuts it off: about 100 characters on TikTok, 125 on Instagram and 210 on LinkedIn. Put the point of the post, the hook or the question, in that space, and keep hashtags and links for later in the caption.

3. 3

   Check words too

   For limits set in words rather than characters, Word Counter gives the word count, reading time and most repeated words. The words per page guide converts word counts into pages.

Emojis and some accented or non-Latin characters can count as two characters on X and in text messages, because of how they are encoded. Line breaks count as characters on most platforms. If a post is right at the limit, leave a few characters spare.
