Check every headline, description and primary text against the real limits for Meta, Google, TikTok, LinkedIn, Reddit and X/Twitter, and see where each platform cuts your copy off before you launch.
Red means the platform won't accept the text; it's over a hard limit. Orange means the ad will run, but the text gets cut off or collapsed behind "See more" in some placements.
Meta publishes recommended lengths per placement, not hard caps. Longer text still runs, but it gets truncated, so this tool only warns in orange.
Each link counts as 23 characters no matter how long it is. Most emoji and Chinese, Japanese and Korean characters count as 2.
Most characters count as 1. Double-width characters, such as Chinese, Japanese and Korean, count as 2.
