What is Social Media Character Counter
This character counter tallies your characters, words, sentences and lines as you type, then shows at a glance whether the text fits each social network. Every platform caps posts, captions and bios at a different length, so instead of guessing you get a live bar for X, Instagram, TikTok, LinkedIn, YouTube, Threads, Bluesky and more. When you go over a limit, that bar turns red and tells you how many characters to cut.
How to use
- Type or paste your caption, bio or post into the box.
- Read the live character, word, sentence and line counts.
- Check the platform bars to see where your text still fits.
- Trim your text until the red bars turn back to normal.
When to use it
Writing a tweet and not sure it fits? Watch the X bar: at 281 characters it turns red and shows how many to cut, while your Instagram caption still has room to 2,200. The same view tells you if a headline fits LinkedIn (220), a YouTube title (100) or a tight Instagram bio (150) before you paste it anywhere.
Frequently asked questions
How are characters counted?
By Unicode code points, which is what you think of as characters, including most emoji counting as one. This matches how the networks report length to you far better than raw byte counts.
Which platform limits are included?
X posts and bios, Instagram captions and bios, TikTok captions and bios, Threads, Bluesky, LinkedIn posts and headlines, YouTube titles and descriptions, Facebook posts and Pinterest descriptions. Limits are public values and can change.
Does it count spaces and line breaks?
Yes. The main character count includes spaces and line breaks because platforms count them too. A separate stat shows the count without spaces if you need it.
Can I share this tool with my text pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Copy link button, and anyone who opens the link will see your exact text ready to go.
