Introducing the Facebook Ad Text Counter

Facebook truncates ad copy that runs too long, hiding your call-to-action behind a “See more” link. The new Facebook Ad Text Counter shows each field’s character count against Meta’s limits — and previews how your ad looks in the feed — before you ever upload to Ads Manager.

What it does

• Three live counters: primary text, headline, and description, each against its limit.
• Recommended-length warnings: turns amber past 125 characters so your message stays visible on mobile.
• Feed preview: see your copy laid out as a real Facebook ad as you type.
• Total characters: a running total across all three fields.
• Client-side: nothing is uploaded — your campaign copy stays private.

Why it matters

Hitting the hard limit isn’t the same as displaying well. Facebook clips primary text around 125 characters, so a counter that warns before the cut — paired with a live preview — protects the part of your ad that actually drives clicks.
