Meta Ad Copy Character Limits by Placement

Most "Facebook ad character limit" cheat sheets quote one number and get the category wrong. There are two, and they behave nothing alike. The hard cap is what Meta's systems will physically accept. Meta's Marketing API documentation for the asset feed spec states that body text has a maximum length of 1,024 characters, and that title and description text have a maximum length of 255 characters. Those are the walls. Paste 900 characters of primary text into Ads Manager and it will save, publish, and deliver. The second number is the one Meta actually publishes for copywriters, and it is not a limit at all. In the Meta Ads Guide, the per-placement figures sit under a heading called "Text Recommendations", alongside "Design Recommendations" and a separate block called "Technical Requirements". Meta puts file size and minimum pixel width in Technical Requirements. It puts character counts in Recommendations. That wording is deliberate: nothing rejects your ad for a 200-character headline, you simply will not see most of it. The practical reading is that the API cap protects the system and the recommendation protects your message. The same asset feed spec also lets you supply up to 5 bodies, 5 titles, and 5 descriptions on a single creative, which is the mechanism behind placement-aware and automatically optimised text. So the real constraint on your writing is never "will this fit in the field", it is "will this be read before it gets cut".

These are the figures Meta published in its Ads Guide for single-image ads, checked in July 2026. They move, so treat this as a snapshot and open the spec page for your own placement and objective before you brief a writer. Facebook Feed: primary text 50-150 characters, headline 27 characters. Instagram Feed: primary text 125 characters, headline 40 characters, maximum 30 hashtags. Facebook Stories: primary text 125 characters, headline 40 characters. Instagram Stories: primary text 125 characters, no headline figure published. Facebook Reels: primary text 40 characters, headline 55 characters. Instagram Reels: primary text 44 characters, no headline figure published. Two things in that list surprise people. First, Facebook Reels is the only common placement where Meta recommends a longer headline (55) than primary text (40), because the Reels overlay treats the headline as the readable line and the primary text as an accessory. Second, Facebook Feed gets a 27-character headline recommendation while Stories and Instagram Feed get 40, so a headline built for Instagram is roughly half again too long for the Feed placement it will also run in. Format changes everything again. On a Facebook Feed carousel under the Traffic objective, Meta recommends primary text of 80 characters, a headline of 20 characters, and a description of 18 characters, which is far tighter than the single-image figures for the same placement. And the description field is the quiet one: Meta's Ads Guide publishes no description recommendation at all for single-image ads on Feed, Stories, or Reels. If a field has no published figure for your placement, that is a strong hint not to put anything load-bearing in it.

Meta does not publish a "See more" character number, and that absence is honest rather than an oversight. Truncation in the feed is a line count, not a character count. The renderer shows a set number of lines and clips the rest, so how much text survives depends on the width of the device, the user's font size settings, the language, whether your copy contains emoji or manual line breaks, and whether the placement renders text above or below the media. The same 130 characters can fit on a wide desktop browser and collapse on a narrow phone held by someone with large system text. That is why the widely quoted "125 characters before See more" is a useful rule of thumb rather than a specification. It roughly matches what Meta recommends for several placements, which is probably where it came from, but it is not a threshold Meta commits to and it will not hold across every device. Anyone quoting it as a hard truncation point is describing an average, not a rule. The defensible way to plan is to assume less visible text than you hope for, and to check the real thing. Ads Manager's ad preview lets you switch placements and see where your copy actually breaks, which takes a minute and settles the argument better than any table, including this one. Preview the placements that will carry most of your delivery, not just the one you built the ad in.

If you run automatic placements, one ad has to work at 150 characters and at 40. The only text you can count on being visible everywhere is roughly the first 40 characters of primary text, because that is the tightest primary-text recommendation Meta publishes across common placements. So write the opening line as if it is the entire ad: the offer, the tension, or the specific claim goes first, and the qualifiers, proof, and links go after the break where only motivated readers will find them. Front-loading is not a stylistic preference on Meta, it is a rendering requirement. A few habits follow from that. Put the number or the noun in the first six words rather than a wind-up clause. Keep the headline under 27 characters if the ad will touch Facebook Feed, since that is the lowest common denominator on the field that stays visible when the primary text collapses. Avoid opening with a manual line break or an emoji row, both of which eat visible lines. And never put the price, the discount code, or the deadline in the description, which may not render at all. The cleaner alternative is to stop making one piece of copy do every job. Because the asset feed spec accepts up to five bodies, titles, and descriptions per creative, you can supply a short variant for Reels and Stories and a longer one for Feed and let Meta serve the fit. Writing that many placement-aware variants by hand is the tedious part, which is where AI copy generation grounded in your brand kit, such as AdPlay.ai's, earns its place. Whatever you use to draft them, re-check the figures on Meta's spec page for your placement before you ship: these numbers have changed repeatedly, and the version in your head is probably a year old.
