How It Works
Select your platforms
Toggle which platforms to check. You can monitor one platform or all six at the same time.
Write or paste your content
Type your caption, post, or script into the text field. Character counts update in real time as you type.
Review limits per platform
Each platform shows a progress bar, characters remaining, and where the visible-text cutoff occurs before "see more".
Popular Use Cases
Cross-Platform Posting
Verify a single piece of content fits every platform before scheduling it across your channels.
Twitter / X Threads
Stay within the 280-character limit for single posts and measure each thread segment individually.
LinkedIn Long-Form Posts
Check that your post exceeds 210 characters so LinkedIn shows the "see more" hook and drives dwell time.
Content Repurposing
Adapt a long-form LinkedIn post to a tight Twitter thread by monitoring character limits side by side.
Pro Tips
Twitter: front-load the hook
On X/Twitter, the first 140 characters appear in the feed preview before 'Show more'. Make the opening count — lead with the most compelling line.
Instagram: use the 125-char rule
Only the first 125 characters are visible before the 'more' tap. Your hook should stand alone in those 125 characters to stop the scroll.
LinkedIn: aim for 210+ characters
Posts under 210 characters do not trigger LinkedIn's 'see more' link, which may reduce engagement. Longer posts signal more substantive content.
Hashtags count toward limits
Every character in a hashtag (including the #) counts toward the platform limit. On Twitter, hashtags in the visible area consume the character budget; put them at the end when possible.
Twitter URL shortening
Twitter automatically wraps all URLs in a t.co short link, which always counts as 23 characters regardless of the original URL length. Factor this into your character budget.
Write once, adapt per platform
Write the core message at the most restrictive limit (280 for Twitter) then expand naturally for platforms with higher limits. Expanding is easier than cutting.
Next step
From one draft to every platform
Counting characters is the first step toward publishing once and reaching everywhere. A real cross-platform strategy shows how to plan that, and our guide on adapting content per platform keeps each version native. Built for content creators who post across many feeds at once.
