LinkedIn Ad Copy Generator: Character Limits, Specs, and Examples
LinkedIn publishes two character limits for every copy field: the one that avoids truncation and the one that gets your ad rejected. Adscreator writes intro text and headlines that land inside the first number, not the second.

Direct answer
A LinkedIn ad copy generator is a tool that writes the text of a LinkedIn ad, the introductory text, the headline, and the description, inside LinkedIn character limits. For a single image ad that means 150 characters of intro text and a 70 character headline before the feed truncates them, against hard ceilings of 3,000 and 200. Adscreator drafts copy that fits the display limit rather than the hard limit, generates the on-brand image to go with it, and hands you variants to test by audience or value proposition. You paste the copy into LinkedIn Campaign Manager yourself, nothing connects to your ad account.
The problem
LinkedIn clicks are among the most expensive in digital advertising, commonly five to ten dollars, so copy that gets cut off mid-sentence is not a cosmetic problem, it is wasted budget on every impression. The trap is that LinkedIn accepts far more text than it displays. You can paste 3,000 characters of intro text into a single image ad and Campaign Manager will take it without complaint, then the feed collapses everything past roughly 150 characters behind a see more link that most members never tap.
How Adscreator handles it
Adscreator writes LinkedIn copy to the limit that matters. Describe your product or paste its URL and it drafts introductory text that lands inside the 150 character display window, headlines that fit the 70 character cap, and descriptions inside 100, in a register that reads as credible to a professional buyer rather than as consumer hype. Carousel card copy is written to the tighter ceiling that format enforces. Every draft arrives with the on-brand single image or carousel creative already sized for the feed, plus variants so an expensive channel is not riding on one untested line. Pricing is flat monthly with no credits, and you export the copy and images and launch them from your own Campaign Manager. Adscreator never touches your ad account.
specs
LinkedIn ad copy limits: the display limit and the hard maximum.
LinkedIn publishes two numbers for most copy fields, and almost every spec sheet on the web reports only one of them. The first is the length that avoids truncation in the feed. The second is the hard ceiling Campaign Manager enforces. Writing to the second number is the most common way to waste a five dollar click. These figures are taken from LinkedIn Marketing Solutions Help and verified in August 2026. Adscreator writes to the display limit in every field below.
| Copy field | Write to this | Hard maximum | Where it appears |
|---|---|---|---|
| Single image ad, introductory text | 150 characters | 3,000 characters | Above the image; the rest collapses behind see more |
| Single image ad, headline | 70 characters | 200 characters | The bold line directly under the image |
| Single image ad, description | 100 characters | 300 characters | Audience Network only, when the image renders under 200 pixels wide |
| Carousel, introductory text | 150 characters | 255 characters | Above the cards; the ceiling is far lower than a single image ad |
| Carousel, card headline | Two lines | Two lines before truncation | On each card, over a 312 x 312 pixel render |
| Carousel, number of cards | 3 to 5 in practice | 10 cards (minimum 2) | One story told across the swipe |
| Call to action label | 45 characters | 45 characters | Carousel cards pointing at a destination URL |
| Ad name | Anything readable | 255 characters | Campaign Manager only, never shown to members |
| Destination URL | Keep it clean | 2,000 characters | Must carry the http:// or https:// prefix |
The gap between the two columns is the whole point. LinkedIn will accept 3,000 characters of intro text on a single image ad and 200 characters of headline, and it will run the ad, but the feed shows roughly 150 and 70 of them. Treat the middle column as the real specification and the hard maximum as a rejection threshold you should never approach.
The see more fold is the only line that matters
Every LinkedIn copy decision comes back to one question: what survives above the see more link. Intro text runs above the image, and LinkedIn collapses it at a point that moves depending on the device, which is why the published guidance is 150 characters rather than a precise figure. On a narrow mobile viewport the fold arrives earlier than that, closer to 70 characters in practice, so the safest structure puts the entire proposition in the first sentence and treats everything after it as a bonus for the small share of readers who expand. That is the opposite of how most B2B copy gets written, where the first line sets context, the second line builds tension, and the offer lands in the third. On LinkedIn the third line frequently does not exist. The practical fix is to write the ad backwards: draft the payoff line first, put it at position one, and only then decide whether any setup earns its place in front of it. The headline underneath the image is a separate 70 character opportunity and it should not repeat the intro text, because a member reading both is reading the same claim twice instead of getting a second reason to click.
Carousel copy is a different specification, not a longer one
Advertisers reasonably assume a carousel is a single image ad with more pictures, and the copy rules quietly disagree. The introductory text ceiling on a carousel is 255 characters against 3,000 on a single image ad, a difference of more than a factor of ten, so copy that pastes fine into one format is truncated by the platform in the other. The file rules invert in the same way: a single image ad accepts up to 5 MB and allows animated GIFs of up to 250 frames, while a carousel accepts up to 10 MB per card but rejects animation entirely. Then there is the render size. Carousel cards display at 312 x 312 pixels, which is small enough that any text baked into the card image needs to be short and set large, and card headlines truncate after two lines regardless of how many characters those lines hold. The upshot is that a carousel is a sequence of very short statements rather than a long story, and the teams that do well with the format write each card as a standalone point that still makes sense if a member never swipes past it.
LinkedIn ad copy examples, before and after the limits
Here is what writing to the fold actually changes. A typical first draft opens "In today's competitive market, finance teams are under more pressure than ever to close the books faster, and manual reconciliation is often the bottleneck holding them back. Our platform helps." That is 213 characters before the offer arrives, so the feed shows a complaint and hides the product. Rewritten to the display limit it becomes "Close the books in 3 days instead of 11. Reconciliation runs automatically for finance teams at 200 to 2,000 employee companies." That is 128 characters, the number leads, the audience is named, and nothing important sits behind see more. The headline underneath then earns its own 70 characters instead of repeating the intro: "See the 3 day close on your own ledger" rather than "Automated reconciliation software." A second example, in recruiting: the weak version is "We help companies hire better engineers faster with our AI screening tool," which is 74 characters of unsupported claim. The stronger version names the mechanism and the proof: "First-round screening for 40 engineering candidates, done by Friday. No recruiter hours." Across every one of these, the pattern is the same: put the concrete outcome and the number in the first sentence, name the reader, and let the headline add a new reason to click. Adscreator drafts several angles at once in this shape, which matters because the only reliable way to find the line that works on a five dollar click is to test more than one.

questions
LinkedIn ad copy generator: the questions people ask.
What is the character limit for LinkedIn ad copy?
A single image ad allows 150 characters of introductory text and a 70 character headline before the feed truncates them, with hard maximums of 3,000 and 200. The description field takes 100 characters before truncation against a 300 character ceiling. Carousel ads are tighter: introductory text caps at 255 characters. Adscreator writes to the display limits, not the ceilings.
How long should LinkedIn ad copy be?
Keep introductory text under 150 characters so it does not collapse behind the see more link, and put your entire proposition in the first sentence, since mobile folds the text earlier than desktop does. Headlines should use most of the 70 characters available without repeating the intro text. Shorter copy is not automatically better, but truncated copy is always worse.
What are the LinkedIn ad copy specs?
For single image ads: 150 characters of intro text, a 70 character headline, and a 100 character description before truncation, on images of 1200 x 628, 1200 x 1200, or 720 x 900 pixels under 5 MB. Carousels allow 2 to 10 cards at 1080 x 1080, up to 10 MB each, with 255 characters of intro text. Destination URLs take up to 2,000 characters.
How do I write a good ad copy on LinkedIn?
Lead with the outcome in the first sentence, because that is often all a member sees before the fold. Name the role or industry you are talking to so the right reader self-selects, use a concrete number instead of an adjective, and make the headline add a second reason to click rather than restate the intro. Then test at least three angles, since LinkedIn clicks are too expensive to guess with.
Is there an AI tool for LinkedIn ad copy?
Yes. Adscreator writes LinkedIn introductory text, headlines, descriptions, and carousel card copy inside LinkedIn character limits from a product description or URL, and generates the matching on-brand image in the right crop. You get several variants to test by audience or value proposition, then paste the copy into Campaign Manager and upload the files yourself. It produces copy and static creative, not video.
How much does a LinkedIn ad copy generator cost?
Adscreator is not open for purchase yet; planned pricing is flat monthly: $39 on Starter, or $29 a month billed yearly, with no credits, so you can draft copy for as many audiences and angles as you want to test. There is no free plan. Your LinkedIn media spend is separate, since LinkedIn bills you directly and enforces its own $10 minimum daily budget per campaign.
