LinkedIn Ad Preview

Mock up a sponsored post and see where the intro text folds and the headline clips, before Campaign Manager and before spend.

0 / 600 characters
Try a sample ad:

0 / 70 before it clips

The sponsored-post preview appears here as you type. It shows where the intro folds behind “…see more” and where the headline clips.

The two cuts that decide whether your ad reads

A single-image ad has two truncation points, and most wasted spend hides behind them.

The introductory text folds behind “…see more” after roughly 150 characters on desktop, sooner on mobile. The headline under the image clips at about 70 characters. Everything past those points is only read by people the visible part already won.

LinkedIn single-image ad limits

The hard limits are what Campaign Manager will accept. The visible limits are what people actually see, and they are the ones worth writing to:

ElementHard limitVisible before truncation
Introductory text600 charactersAbout 150 on desktop, about 100 on mobile
Headline200 charactersAbout 70

How to use the ad preview

  1. Write or paste your introductory text and headline, or start from a sample ad.
  2. Check the mobile view first. It folds soonest, and most feed impressions are mobile.
  3. Make the visible part carry the offer. If the value proposition sits after the fold, move it up.
  4. Match the button to the landing page's ask. A Download button on a demo form costs trust and quality score.

Writing intro text that survives the fold

  • Lead with the problem or the number, not your company name. The header already names you.
  • One idea before the fold. If two clauses compete, the reader takes neither.
  • Skip “We're excited to announce”. It spends the fold on your feelings.
  • Say who it is for early. Qualified readers lean in, and unqualified clicks cost money.

Frequently asked questions

Can you preview a LinkedIn ad before it runs?
Yes, twice. This tool shows the copy cuts while you are still drafting, with nothing set up. Then Campaign Manager shows an exact render of the final ad once you build the campaign. Checking the copy here first means fewer rebuild loops there.
What are the character limits for LinkedIn ads?
For single-image ads: introductory text allows 600 characters but folds behind “…see more” at roughly 150 on desktop and about 100 on mobile. The headline allows 200 characters but clips around 70. The truncation points matter more than the hard limits, because most viewers never expand the ad.
What image size do LinkedIn ads use?
1200 by 627 pixels, a 1.91:1 ratio, for single-image ads in the feed. Square 1080 by 1080 is also accepted and takes more vertical space on mobile. Keep files under 5 MB as JPG or PNG.
Why does my ad headline get cut off?
The headline field accepts 200 characters, but the feed placement only shows about 70 before clipping, less when the CTA button is long. Front-load the offer so the clipped version still makes sense, or keep the whole headline under 70.
Does the description field show anywhere?
Rarely. The description on a single-image ad appears mainly on some placements outside the feed, like the LinkedIn Audience Network. Write it, but never put anything there that the intro and headline don't already carry.
Is this an exact render of my ad?
No, deliberately. It is a labelled mockup in this site's styling that gets the load-bearing details right: the intro fold, the headline clip, and the layout order. Campaign Manager gives the pixel-exact render once the campaign exists; this tool exists so your copy is ready before that.
