Why it Matters

Facebook truncates ad copy that runs too long, hiding your call-to-action behind a 'See more' link or cutting a headline mid-word. Knowing each field's character count before you publish keeps your message intact across the feed, Stories, and the right column. A live preview turns guesswork about how copy will display into something you can see.

What this tool does

The Facebook Ad Text Counter counts the characters in your ad’s primary text, headline, and description, compares each against Meta’s limits, and shows a live Facebook feed preview so you can see exactly how your copy will display before you publish.

How it works

Each field is measured by Unicode code points and checked against two thresholds: Meta’s hard limit and the recommended length for clean display. Fields turn amber when they pass the recommended length and red when they exceed the limit, while the preview re-renders as you type. The counting is a pure function, so the same copy always produces the same counts.

Privacy

Everything runs locally in your browser. Your ad copy is never uploaded, logged, or stored.

Frequently Asked Questions

What are Facebook's ad character limits?

In Meta Ads Manager the practical field maximums are about 500 characters for primary text, 100 for the headline, and 30 for the link description. Facebook recommends keeping primary text near 125 characters and headlines near 40 so nothing gets truncated on mobile.

Why does the counter warn me before I reach the limit?

Hitting the hard limit isn't the same as displaying well. Facebook often truncates primary text after roughly 125 characters with a 'See more' link, so the counter turns amber once you pass the recommended length — even though you're still under the maximum — to protect your call-to-action.

Do emojis count as one character?

The counter measures Unicode code points, so most emojis count as a single character. Note that some platforms count complex emoji (like skin-tone or flag combinations) differently, and emojis can also take up more visual space, so use them deliberately in short fields.

Is the description field required?

No. The link description is optional and only appears in some placements. When it does show, it's limited to about 30 characters, so the counter tracks it separately and marks it optional.

Is my ad copy sent anywhere?

No. The counter runs entirely in your browser. Nothing you type is uploaded, logged, or stored — refreshing the page clears all fields, so your campaign copy stays private.
