Social Media Character Counter - Free Online SEO Tool

The Social Media Character Counter is a free online tool that counts characters in real-time and checks your text against the specific limits of major social platforms. Whether you're crafting a tweet, LinkedIn headline, Instagram caption, or Google Ads copy, this tool helps you stay within platform restrictions so your content displays correctly without unwanted truncation.

Key Features

• Real-time character counting as you type or paste your content
• Built-in limit checks for Twitter/X, LinkedIn Post, LinkedIn Headline, Facebook Post, Instagram Caption, Instagram Bio, and TikTok Caption
• Additional support for YouTube Title, YouTube Description, Pinterest Description, Google Ads Headline, and Google Ads Description
• Clear display of platform limits so you instantly know how much room you have left

How to Use the Tool

Type or paste your post into the text box, and the tool will automatically calculate your character count while comparing it against the limits of each supported platform. Simply review the platform limits section to see whether your content fits within each network's requirements before publishing.

Best Practices

• Check character limits before finalizing captions to avoid awkward cutoffs in feeds or search results
• Optimize headlines and ad copy separately, since limits vary significantly between platforms like Google Ads and LinkedIn
• Keep your most important message within the first visible characters, especially for platforms that truncate longer posts
• Recheck your text after edits, since even small changes can push you over a platform's limit

This character limit checker is essential for social media managers, marketers, and content creators who publish across multiple platforms and need a fast, reliable way to ensure their posts, captions, and ads always fit within each network's specific character requirements.
