Here are the recommended specs.

  • Ratio: 1:1
  • Recommended resolution: Minimum 1080 x 1080 pixels, maximum 4320 x 4320 pixels (all images will be scaled to 312 x 312 pixels)

• Text:
  • Ad name (optional): 255 characters
  • Individual headlines: 45 characters
  • Introductory text: Maximum 255 characters. However, LinkedIn recommends using 150 characters to avoid truncation on devices
  • Headline text: Maximum of two lines for each card before being truncated

• Slides:
  • Number of carousel slides: Between 2-10
  • Maximum file size: 10 MB

• URL:
  • Landing page URL: Required

Once a LinkedIn carousel ad is published, it can’t be edited, so make sure you double check every slide and design.

Along with these technical specifics, every ad carousel must also follow LinkedIn advertising guidelines, otherwise it will be rejected.

How to create a LinkedIn carousel ads campaign

Creating a LinkedIn carousel ad campaign takes a little more behind-the-scenes work before you hit Post.

Here is how to create a successful campaign:

1. Choose your campaign objective

LinkedIn carousel ads can cover every step of a marketing funnel, from brand awareness to conversions.

First, open your LinkedIn Campaign Manager Account. Keep in mind, this account must be linked to your Company Page to run a carousel ad campaign.

Next, click Create Campaign at the top of the screen and select Advanced. Give the campaign a name and pick an overarching goal for your carousel ad from these options:

• Brand awareness. To tell your brand’s story and get on a target audience’s radar
• Website visits. To increase traffic to your website
• Engagement. To boost likes, comments and shares on your content
• Lead generation. To gather information about a potential lead with a pre-filled form using their LinkedIn profile data
• Website conversions. To drive more leads to your website

At this point, you should see something like this:

2. Set a budget based on your objective

Similar to other social media platforms like Facebook or X, LinkedIn carousel ads have budget settings to control how much you spend.

Your LinkedIn carousel ad should tie directly to your campaign. LinkedIn recommends using the following bid strategy:

• For website visits. Select bid by cost per 1,000 impressions (CPM)
• For lead generation. Choose the bid by cost per click (CPC) option
• For increased clicks. Let LinkedIn take over the bids with automated bidding

If you are just starting with LinkedIn ad carousels, don’t worry—LinkedIn will automatically select the best bid type for your campaign based on the selected goal.

To ensure the campaign doesn’t go over budget, turn the budget optimization setting to on. Then, set a daily or lifetime budget and choose a timeframe for how long the campaign should run.

3. Build carousel ads based on campaign objectives

Start to input the content for your LinkedIn carousel ad campaign.

Under Ad format, select Carousel image ad:

• Save

Next, upload the files for the campaign, either in JPEG, PNG or MP4 formats. Add a headline for each slide and a destination URL for where the audience will land if they click on it. Once the files are uploaded, arrange the order of the carousel so it flows and engages your audience.

Don’t forget to click ALT to add alt text to each image in your carousel.

4. Narrow down your target audience

One of the best features of LinkedIn carousel ads is its audience targeting.

At this stage of the campaign build, set specific parameters around who you want to market your carousel to. Select attributes based on where your target audience’s industry, demographics and interests are to optimize the campaign’s reach. Or, create an audience using LinkedIn’s lookalike audiences feature to show it to people with similar characteristics to your current and past customers.

• Save

Once you’re done, click Save audience at the bottom of your screen.

5. Launch, test and optimize

Your carousel will appear in your Campaign Manager dashboard. Simply set it to active to get it up and running.

Remember, your content and campaign goals will impact how well your carousel performs. It can also vary depending on the selected target audience or even the LinkedIn algorithm. To maximize your ad spend, it’s crucial to monitor it and test different strategies with your audience:

• A/B test the number of cards. A fewer number of cards can get your point across quickly, while longer carousels allow you to tell more of a story. Test out different carousel lengths to see which format your audience likes to engage with.
• Test the sequence order. The first slide in your sequence is the first thing a person will see, but the second slide will also be slightly visible. If you swap the two, will you get more impressions? Try it out.
• Tweak your audiences. A/B test carousels with different demographics, messaging and targeting to optimize impressions and results.

Sprout Social keeps track of campaign performance inside the LinkedIn Analytics Dashboard. It will monitor LinkedIn audience demographics to help you understand who your followers are and keep tabs on paid campaign performance metrics.
