LinkedIn Ad Character Limits: The Reference for Every Format

LinkedIn ad character limits matter less for the hard maximum and more for where your text gets cut off. Intro text truncates at roughly 150 characters with a “see more” link, and a headline over about 70 characters is cut permanently with no way to expand it, so anything that matters, your hook, your value, your call to action, has to sit before those cuts. This guide gives the character limits for every ad format and field, including lead gen forms and the desktop-only formats, shows where LinkedIn truncates each one, and explains why the cut-off point, not the field maximum, is what you write to. It is the copy-length companion to the image and video ad specs; this one is about words.

Key takeaways

• The number that matters is the truncation point, not the field maximum: intro text cuts at about 150 characters, and headlines over about 70 are cut permanently.
• Single image and video intro text allows up to 600 characters, but only the first 150 or so show before “see more.”
• Carousel intro text maxes out lower, at 255 characters, and card headlines run 45 (with a link) or 30 (with a lead gen form).
• Text ads and dynamic ads are desktop-only and tiny: a 25-character text-ad headline, and a 50-character dynamic headline.
• Lead gen forms have their own limits: a 60-character headline, a description that truncates near 70, and up to 2,500 characters of privacy disclaimer.

What are the LinkedIn ad character limits?

Here is the reference, field by field, for the main formats. Recommended means the point before truncation where your text still shows in full; maximum is the hard field limit.

Field maximums shift over time and occasionally by placement, so treat these as a working reference and confirm anything critical in Campaign Manager as you build the ad.

Where does LinkedIn truncate your ad?

Two cut-off points decide what people actually read. The first is the intro text “see more” cut, which falls around 150 characters in the feed. Up to that point your text shows in full; past it, the reader sees a truncated line and a “see more” link they have to click to read the rest. The second is the headline cut, and this one is harsher: a headline beyond about 70 characters is simply cut off, with no “see more” and no way for the reader to expand it, so any words past 70 are lost. There is no separate, friendlier mobile limit to rely on; LinkedIn applies a single truncation point per field, and since most of your audience is on mobile, the feed cut is what you write to. Carousel intro text has a lower hard ceiling than single image, 255 characters rather than 600, and each card headline is short at around 45 characters. The practical rule is to treat 150 for intro text and 70 for headlines as your real limits, not the larger field maximums.

The front-load rule

The single habit that makes LinkedIn copy work within these limits is what we call the front-load rule: put the hook and the offer before the cut. Because the first 150 characters of intro text and the first 70 of the headline are all that reliably show, your most important words, the problem you solve, the specific value, and the reason to click, must live in that opening. Treat everything after “see more” as a bonus that most people will never read, not as where your argument builds. In practice that means leading with the payoff rather than a windup, naming your audience or their problem in the first line, and making sure your call to action is visible without a click. If your value proposition only appears in character 300, most of your audience never sees it.

Why character limits affect cost, not just copy

On most formats, truncation only costs you attention. On some video objectives, it can cost you money: you are charged when a user clicks “see more” to expand the intro text, so long intro copy that forces the click can quietly add to your spend without adding value. That turns writing to the limit into a budget decision as well as a creative one. Keeping intro text within the visible window means more of your audience reads the whole message without a click, and on those video objectives it avoids paying for expansions that do not move anyone closer to converting. Short, complete-in-view copy is cheaper and clearer at the same time.

What about lead gen forms and desktop-only formats?

Two format groups have their own rules worth calling out. Lead gen forms give you a 60-character headline, a description that shows about 70 characters before truncating (200 maximum), and up to 2,500 characters of custom privacy disclaimer, so the offer has to be clear and short while the legal text has room. Text ads and dynamic ads, meanwhile, run only on desktop and are the most constrained formats on the platform: a text ad gets a 25-character headline and 75-character description, and a dynamic ad gets a 50-character headline, 70-character description, and an 18-character call-to-action button. If you are writing for those, there is no room for anything but the single clearest benefit and a direct action.

How do you write to the limits?

Write the ad to the cut, not the field. Draft your intro text so the hook and offer land in the first 150 characters, then add detail after only if it genuinely helps. Keep the headline under 70 characters and make it a clear, specific statement of value rather than a clever phrase that gets chopped. Use one call to action, not three, so the single action you want is unmistakable. For carousels, remember the intro ceiling is lower and each card headline is short, so write tight. For message and conversation ads, shorter consistently outperforms the maximum, because these land in an inbox and a wall of text gets ignored. And always preview the ad in Campaign Manager on both desktop and mobile before launching, since the feed cut is where your copy meets reality.

Common character-limit mistakes

The usual mistakes come from writing to the field maximum instead of the visible window. Burying the value proposition after the “see more” cut, where most readers never go, is the most common and the most costly. Writing a headline over 70 characters and losing the end of it is close behind. Treating the 600-character intro maximum as a target and producing a wall of text is another. Stuffing multiple calls to action into one ad splits the reader’s attention. Forgetting that carousel intro text caps lower, at 255, or that text and dynamic ads are desktop-only, leads to copy that will not fit or will not show where you expect. And never previewing on mobile, where most of your audience is, means you find the truncation after you have paid for the impressions.

Write for the cut, not the field

Here is the thread. LinkedIn’s character limits are not really about the maximum you are allowed; they are about the much smaller window that actually shows, around 150 characters of intro text and 70 of headline. Write your hook, your value, and your call to action inside that window, keep one clear action, and preview on mobile, and your ad communicates fully before anyone has to click “see more.” That protects both your message and, on some video objectives, your budget, which keeps the ad working toward engagement and relevance that actually convert. If you want your LinkedIn ad copy and creative built to perform within the limits and toward pipeline, you can book a demo.

Frequently Asked Questions

Q1. What is the character limit for LinkedIn ad intro text?

The intro text field allows up to 600 characters for single image, video, and document ads, but only about the first 150 characters show in the feed before a “see more” link. Carousel intro text maxes out lower, at 255 characters. The practical limit is roughly 150 characters, because that is what most people read without clicking to expand.

Q2. What is the LinkedIn ad headline character limit?

For single image and video ads, the headline field holds up to 200 characters, but only about the first 70 display, and anything beyond 70 is cut off permanently with no “see more” option. So keep headlines under about 70 characters. Document ad headlines run 60 to 70, dynamic ad headlines 50, and text ad headlines just 25 characters.

Q3. Where does a LinkedIn ad get cut off?

At two points. Intro text is truncated around 150 characters in the feed, after which readers see a “see more” link. Headlines are cut at about 70 characters with no way to expand. LinkedIn applies a single truncation point per field rather than a looser mobile one, so write to the feed cut, and put your hook, value, and call to action before it.

Q4. What are the character limits for LinkedIn message and conversation ads?

Message ads allow a subject line up to 60 characters, a message body up to 1,500, and a call-to-action button up to 20, though much shorter performs better in an inbox. Conversation ads use shorter message bubbles, around 500 characters each, with call-to-action buttons up to 25 characters and up to five buttons. For both, brevity wins, because these formats land as messages.

Q5. What are the LinkedIn lead gen form character limits?

A lead gen form allows a 60-character headline, a description that shows about 70 characters before truncating with a 200-character maximum, and up to 2,500 characters of custom privacy disclaimer. The internal form name can be up to 256 characters but is not shown to users. Keep the headline and description short and clear, since the offer has to land fast.

Q6. Are LinkedIn text ads and dynamic ads limited to desktop?

Yes. Text ads and dynamic ads (such as spotlight and follower ads) appear only on desktop, not in the mobile feed, and they are the most character-constrained formats. A text ad gets a 25-character headline and 75-character description; a dynamic ad gets a 50-character headline, a 70-character description, and an 18-character call-to-action button.

Q7. Do longer LinkedIn ads perform worse?

Not because of length itself, but because length past the cut is wasted. Copy after the “see more” line is read by a small fraction of your audience, so if your argument lives there, it is effectively invisible. Shorter copy that lands the hook and offer in the visible window usually performs better, and on some video objectives it also avoids the charge for “see more” expansions.

Q8. What is the difference between character limits and ad specs?

Character limits govern your copy, how many characters each text field allows and where it truncates, while ad specs govern the creative file, such as image dimensions, aspect ratios, video length, and file size. You need both right: copy that fits the visible window and a creative that meets the format’s technical requirements. This guide covers the copy side.
