Character Limit Checker
Every social media platform enforces different character limits, and exceeding them means your post gets cut off, your message loses impact, or your content simply fails to publish. This tool checks your text against the character limits for all major platforms simultaneously — Twitter/X (280 characters), LinkedIn posts (3,000), LinkedIn headlines (120), Instagram captions (2,200), YouTube titles (100), TikTok captions (2,200), and meta descriptions (160). As you type or paste your text, color-coded indicators show you exactly where you stand for each platform: green when you are well within limits, yellow when you are approaching the boundary, and red when you have exceeded it. No more guessing, no more truncated posts, no more wasted time rewriting content that does not fit.
When should you use it?
- check_circle Drafting a Twitter/X post and trimming it to fit exactly within the 280-character limit before publishing
- check_circle Writing a LinkedIn headline for a job profile and ensuring it stays under the 120-character cutoff
- check_circle Crafting an SEO meta description that maximizes the 160-character limit without exceeding it
- check_circle Repurposing a blog post excerpt across multiple social platforms and checking which ones need editing
- check_circle Writing YouTube video titles that are compelling but stay under the 100-character display limit
How it works
The character counting engine runs entirely in your browser, providing instant feedback as you type with zero server delay. Each keystroke triggers a recalculation of your text's total character count, which is then compared against each platform's known character limit.
The tool uses standard JavaScript string length measurement, which counts each Unicode character as one unit. This matches how most platforms count characters for their limits. The results are displayed as both a raw count (e.g., '142 / 280') and a visual progress bar that fills and changes color as you approach the limit. The color thresholds are set at 80% (green to yellow transition) and 100% (yellow to red transition).
All seven platform limits are checked simultaneously, so you can write once and immediately see which platforms your text fits. This is particularly useful when repurposing content across multiple channels — you can see at a glance that your text works for LinkedIn and Instagram but needs trimming for Twitter, without having to check each platform separately.
