Meta recommends 125 characters of primary text for most placements, a headline of 27 characters in the Facebook feed and 40 on Instagram, and a 25 character description. The exact cut-off depends on the device and placement, so read the preview as a guide. Nothing you type leaves your browser.
Meta's recommended lengths
Meta does not publish the exact number of characters shown before See more, and it changes by device and placement. About 125 characters on mobile is the common working figure, so treat the preview as a guide.
Primary text: 125 characters for most placements. Meta says it should span one to three lines at most. Instagram Reels suggests 44 characters and Facebook Reels 40.
Headline: 27 characters in the Facebook feed, 40 in the Instagram feed and Facebook Stories.
Description: 25 characters.
Writing copy that survives the cut
Put the hook and the offer in the first line, because many people never tap See more. Longer copy can still work below the fold, but the first 125 characters have to earn the tap. The guide at /guides/facebook-ad-copy covers structure, and the hook generator at /tools/ad-hook-generator gives you openers to test.
Frequently asked questions
- What is the character limit for Facebook ad primary text?
- There is no hard limit that stops you publishing, but Meta recommends about 125 characters for most placements, and longer text may be cut off behind See more.
- How long should a Facebook ad headline be?
- Meta recommends 27 characters in the Facebook feed and 40 on Instagram. Short headlines are less likely to be cut and easier to read at a glance.
- Does the description show on every placement?
- No. Some placements hide it, and for some video ad types the mobile feed hides the headline and description entirely, so never put essential information only in the description.
