What Is a Social Media Character Counter?
A social media character counter shows how many characters your post, caption or bio uses, and how many you have left before you hit the character limit. Every platform has its own limits and counts emojis, links and line breaks in its own way. This free tool counts your text exactly like X (Twitter), Instagram, LinkedIn, TikTok, Facebook, YouTube, Threads, Bluesky and Pinterest do, and shows what gets cut off before "more".
Why use a character counter for social mediaAvoid cut-off posts
Posts that are too long get cut off or blocked. See the exact character count before you hit publish.
Keep your hook visible
Most platforms hide text behind "more". The preview shows what people see before they tap.

Frequently Asked Questions
Everything you need to know about social media character limitsWhat is a social media character counter?
A social media character counter counts the characters in your post and compares them to each platform's character limit. This one counts links, emojis and line breaks the way each platform does, and shows what gets cut off before "more".
What are the character limits for each social media platform?
In 2026 the main post limits are: X (Twitter) 280 (25,000 with Premium), Instagram 2,200, LinkedIn 3,000, TikTok 4,000, Facebook 63,206, Threads 500, Bluesky 300 and Pinterest 500 for a pin description. YouTube allows 100 characters for a title and 5,000 for a description.
What is the Twitter character limit?
A post on X (Twitter) can be up to 280 characters on a free account. With X Premium you can write up to 25,000 characters, but only about the first 280 show in the timeline before "Show more". Your X bio can be up to 160 characters.
Do links and emojis count on X (Twitter)?
Yes. Every link counts as exactly 23 characters, no matter how long it is, because X shortens links with t.co. Most emojis count as 2 characters, and so do Chinese, Japanese and Korean characters. The counter handles this automatically.
What is the Instagram caption length limit?
An Instagram caption can be up to 2,200 characters, but only roughly the first 125 show in the feed before "more". Instagram comments can also be up to 2,200 characters, and your bio up to 150.
How many hashtags can I use on Instagram?
Instagram has rolled out a limit of up to 5 hashtags per post and reel, replacing the old limit of 30. The counter warns you if you use more than 5.
What is the LinkedIn character limit?
A LinkedIn post can be up to 3,000 characters. The feed shows roughly the first 210 characters on desktop, and often fewer on mobile, before "…see more". Your headline can be up to 220 characters and your About section up to 2,600.
What is the TikTok caption limit?
TikTok captions can be up to 4,000 characters when you post in the app. The limit used to be 2,200, and some third-party scheduling tools still use the old limit. Your TikTok bio can be up to 80 characters.
What is the Facebook character limit?
A Facebook post can be up to 63,206 characters. On desktop, posts collapse after about 477 characters with "See more", and sooner on mobile.

A YouTube title can be up to 100 characters, but only around the first 70 usually show in search. Descriptions can be up to 5,000 characters, and all tags combined up to 500. Try our free YouTube Tag Generator for tags that fit.
What is the Threads character limit?
A Threads post can be up to 500 characters, plus an optional text attachment of up to 10,000 characters. Threads uses one topic tag per post, and your bio can be up to 150 characters.
Which social media platform has the shortest character limit?
X (Twitter) has the shortest post limit at 280 characters for free accounts, followed by Bluesky at 300 and Threads at 500.
How many words is 280 characters?
Around 40 to 55 words, depending on how long your words are. An average English word is about 5 letters plus a space, so 280 characters is roughly one short paragraph.
How many words is 2,200 characters?
Around 300 to 450 words. That's the full Instagram caption limit, but remember that only the first ~125 characters (about 20 words) show before "more".
Why is my character count different on each platform?
Platforms count characters differently. X counts every link as 23 characters and most emojis as 2. Instagram, LinkedIn and TikTok count most emojis as 2, while Threads and Bluesky count each emoji as 1.
Does this character counter count emojis correctly?
Yes. Combined emojis like 👨👩👧 or flags are counted the way each platform counts them, so the number you see matches what the app will accept.
Do spaces and line breaks count as characters?
Yes. On every major platform, spaces, line breaks, punctuation, hashtags and @mentions all count toward the character limit. The counter also shows your character count without spaces.
Can I use it as a regular character counter?
Yes. Besides the platform limits, the tool shows your total characters, characters without spaces, words, lines, hashtags, mentions, emojis and links, so it works as a general character and word counter too.
Can I check one post for all platforms at once?
Yes. The All platforms list shows instantly whether your text fits X, Instagram, LinkedIn, TikTok, Facebook, YouTube, Threads, Bluesky and Pinterest. Click a platform to see its full preview.
How do I post the same text on several platforms?
Check that your text fits every platform here, then use SoMePoster to schedule it to 25+ platforms in one go, without copy-pasting between apps.
Is this character counter free?
Yes. The character counter is completely free, with no sign-up, no limits and no login. Just start typing.
Is my text stored anywhere?
No. Everything runs locally in your browser. Your text is never uploaded or saved, and nothing is kept when you close the page.
