How It Works
Step 1: Choose your platform
Select the platform you are posting to from the dropdown — Twitter/X, Instagram, LinkedIn, Facebook, TikTok, SMS, or a Google meta description. The tool automatically loads the exact character limit for your selection so you always compare against the right number.
Step 2: Paste or type your text
Enter your copy in the text box. The character count updates live with every keystroke, and the progress bar fills as your text grows, so you can see at a glance how close you are to the edge.
Step 3: Read the status bar
A green label shows how many characters you have left, while a red label warns you clearly when you have gone over the limit. The color coding removes any guesswork about whether your post will publish correctly.
Step 4: Trim and repost
Shorten your text until the status is green and comfortably within range, then copy the final version and publish with confidence that it will not be truncated.
Real-World Examples
Twitter/X Post (Social Media Manager): Your draft runs 312 characters but Twitter allows 280. The counter shows you are 32 characters over and flags the post in red. You tighten the wording, hit 278 characters, and your post publishes cleanly without being cut off mid-sentence.
Google Meta Description (SEO): Google truncates meta descriptions around 155–160 characters. You paste your draft and see it is 198 characters, so the ending would be hidden. You rewrite it to 152 characters and the full, compelling description now displays in search results.
SMS Campaign (Marketer): You are sending a promotional text that allows 160 characters per message. The counter flags your 173-character draft, so you cut a few words and fit the entire message into a single, complete text that delivers the full offer to your audience.

Use Cases
Social Media Managers
Fit posts, captions, and bios to each platform's exact limits so your message is never cut off or rejected by the network. Keep a library of correctly sized copy for recurring campaigns.
SEO Specialists
Write meta descriptions that display fully in search engine results to maximize click-through rates. A description that ends mid-sentence loses credibility and clicks.

Frequently Asked Questions
Q: What is a character limit?
A: A character limit is the maximum number of characters — letters, spaces, and punctuation — that a platform allows for a single post, bio, or text field.
Q: Does a space count as a character?
A: Yes. Spaces count toward the character total on nearly every platform, including Twitter and Instagram, so you must account for them in your copy.
Q: What is Twitter's character limit?
A: Twitter/X allows 280 characters per post for standard accounts. This tool checks your text against that exact limit automatically.
Q: Why is my post getting cut off?
A: Your text likely exceeds the platform's limit. The counter shows exactly how many characters you are over so you can trim it down to fit.
Q: Is this tool free to use?
A: Yes, it is completely free, requires no signup, and runs entirely in your browser with no data leaving your device.
Q: Can I check multiple platforms at once?
A: Yes. Paste your text once, then switch platforms in the dropdown to instantly see how it measures against each platform's limit.
