Facebook Ad Preview
See how your Facebook ad reads before you spend on it: your image in the 4:5 feed shape, with your page name, primary text, headline, description and button in a generic feed mockup. The primary text folds at 150 characters, the top of Meta's recommended range, and the tool warns you when the headline runs past Meta's recommended 27. Switch to Instagram, Stories or TikTok in one click. An approximate preview, drawn in your browser: nothing is uploaded.

Frequently asked questions
How long should Facebook ad text be?
Meta's ads guide recommends 50 to 150 characters of primary text and 27 for the headline in the Facebook feed (checked on 3 November 2026). Those are recommendations, not limits: longer text runs, but the app may cut it with See more.
Is this exactly how Facebook will show my ad?
No. It's a generic mockup drawn with neutral shapes, not Facebook's interface, and the real layout depends on the phone. Use the preview in Ads Manager for the final check.
What image size works for the Facebook feed?
4:5, with 1440 × 1800 px recommended by Meta's ads guide, as a JPG or PNG of up to 30 MB.
Which buttons can I preview?
Shop now, Learn more, Sign up, Order now, Get offer and Contact us, all in Meta's list of call-to-action buttons. Which ones your ad can use depends on your objective and your industry.
