With an active user base of over 2 billion a day, Facebook dominates the social media advertising space as the leading platform for lead generation and conversion. Meta offers a wealth of advertising formats and tools, cementing its significance as a crucial sales channel for ecommerce and service-based businesses.
As you set up a campaign, it’s important to scrutinize the Facebook ad size and select Facebook ad specs tailored to your advertising objectives and target audience. In 2024, social media is a highly saturated and competitive space, and advertisers must experiment with Meta ad specs to capture and retain audience engagement.
An effective and evocative ad campaign is a combination of a persuasive ad copy with immersive visuals and an interactive format. Incorporating images and videos increases engagement and organic reach considerably, compelling users to explore further by visiting the website. However, if you don’t pay attention to elements like Facebook ad size and Facebook video ad specs, your creative efforts will be wasted.
This detailed guide will help you develop a keen understanding of Facebook ad specs and using the right Facebook ad size to ensure your ads offer an engaging user experience.
Facebook Ad Specs: Why Does Facebook Ad Size Matter?
Meta offers advertisers a plethora of formats, placements and tools to tailor the advertising experience to user preferences, especially the devices they’re using to access Facebook. Understanding Facebook ad specs is crucial to take advantage of Meta’s cutting-edge toolkit and drive conversion rates. Facebook ad size and dimensions matter significantly as ads must integrate seamlessly into the news feed without disrupting the user experience.
Familiarizing oneself with Meta ad specs is crucial to avoid technical issues that discourage users from engaging with your ads. Advertisers can explore a variety of formats and placements, including articles, messenger ads, carousel ads, video ads and stories. Let’s examine the benefits of using the right Facebook ad size and dimensions.
An Immersive User Experience
Facebook ad dimensions and size matter significantly as these elements define the user experience. Publishing a campaign with an inaccurate Facebook ad image size will render that campaign worthless as the image will not support the dimensions and resolution required to ensure effective engagement. Users will undoubtedly scroll past the faulty ad, paying it no attention as they explore the never-ending supply of content and reels.
Advertisers must strictly adhere to the Facebook ad sizes and dimensions, particularly Facebook video ad specs to eliminate technical errors that disrupt audience engagement. Selecting the right Facebook ad size is the first and foremost step in curating a professional brand image and making advertisements visually aesthetic.
Maintaining Consistency
In digital advertising, brand image refers to the overall social footprint of the brand, curated with consistent branding efforts to curate a visually appealing aura for a business. Branding demands consistency to ensure all advertisements that are closely aligned with the color scheme, logo, language and other marketing elements that symbolize the brand’s ethos.
Facebook ad specs are instrumental in ensuring consistency and curating a brand image that aligns seamlessly with the brand’s core identity and marketing vision. Ensuring all Facebook video ad specs and Facebook ad dimensions are uniform across all campaigns and platforms allows advertisers to earn consumer trust and recognition.
Higher Conversion Potential
Campaigns with optimal Facebook ad sizes and dimensions drive higher conversions as they ensure a positive user experience. Setting up a campaign with the right Facebook video ad specs will make the video more compelling and highly likely to nurture and convert leads. In contrast, an ineffective campaign with inadequate Facebook carousel ad specs will offer little or no returns.
Greater ROAS
Return on ad spending (ROAS) is a vital metric that allows advertisers to monitor ad performance and adopt a calculative spending approach. Facebook ad sizes and dimensions are closely tied to ad performance and ROAS because the Meta ad specs determine the click-through-rates and conversion rates. in fact, selecting the right Facebook ad sizes is essential for maximizing your ad’s effectiveness, while understanding how to calculate Facebook CPA helps in measuring and optimizing your campaign’s cost efficiency.
For instance, inadequately formatted Facebook ad image size will not load quickly, resulting in a higher bounce rate as users are unable to interact with the image. In contrast, well-formatted Facebook carousel ad specs will drive website traffic and decrease bounce rates by enticing users with high-quality images or videos.
Compliance with Meta Ad Specs
Meta requires advertisers to comply with its community guidelines and policies, particularly while optimizing Facebook ad specs and publishing content. Understanding metrics like the appropriate Facebook ad size, image size and Facebook video ad specs eliminates issues like community violations and rejected ad campaigns.
Ensuring compliance with the Meta ad specs and community guidelines reduces the chance of temporary restrictions and permanent bans from the platform. We strongly urge brands and advertisers to familiarize themselves with Facebook ad specs and other guidelines to maintain a positive relationship with Meta and their target audience. Understanding ad specs is crucial for optimizing Facebook interest targeting and ensuring your ads reach the right audience effectively.
Facebook, like other social media platforms, is constantly upgrading its advertising toolkits with innovative display formats and placements. In order to make these changes effective, Meta routinely improves and updates its algorithms, requiring advertisers to learn new Facebook ad specs to maintain audience engagement.
Staying breast with algorithm and display format changes is important to embrace the right Facebook ad size and ensure your campaigns are well-optimized for higher conversions in today’s rapidly evolving social media landscape.
Understanding Facebook Ad Specs
Once you create your Facebook ad account, and you explore the Meta ad specs, you will notice that images, videos and feed ads have varying sizing and dimension requirements. Let’s examine the Facebook ad sizes and dimensions for the most popular ad types.
1. Facebook Ads Sizes for the User’s Feed

Facebook feed ads are the most popular and effective advertising placement, which also makes it the most heavily saturated and contested. It’s common for brands to compete against innumerable competitors vying for the same ad placement, and this competition further accentuates the need for selecting the right Facebook ad size.
For feed ads, advertisers can choose between a video ad, image ad and even a carousel ad. Based on the Meta ad specs, advertisers must ensure that the image or video used is relevant to the ad copy.
Facebook Feed Image Ads
Image ads are much easier to design than video ads, and while video marketing is considered trendier, Facebook ads with a single image are still considered effective for driving website traffic.
According to Facebook ad specs, images containing more than 20% text are considered ineffective, and Meta issues a “reduced delivery” notification. Advertisers can use the Meta tool to ensure their images have the right amount of text to capture attention.
Here are the specifications for Facebook ad image size:
Facebook ad image size: Min 1080 x 1080 pixels
Image file: JPG or PNG
Image ratio: 1.91:1 to 1:1
Image Text: Less than 20%
Text: 125 characters (without link)
Facebook Feed Video Ads
Video marketing has taken social media by the storm, and using appropriate Facebook video ad specs is of the utmost significance to capture and retain user engagement. Social media platforms are highly saturated with interactive, high-definition video content, creating an intensely competitive environment where advertisers cannot afford to make even the smallest of mistakes.
It’s pertinent to note that Facebook feed video ads are different from in-stream video ads that come with a 10-second duration limit. These ads can be longer, and we strongly recommend advertisers to use the highest-resolution clips that don’t contain any black bars, pillar boxing or letters. We also recommend adding captions and sounds to make the ads interactive with compelling calls-to-action.
In addition to optimizing video ads, incorporating Facebook GIF ads can further enhance your advertising strategy. GIF ads are short, looping animations that capture attention quickly, making them ideal for engaging users with brief, impactful messages.
Here are the Facebook video ad specs for feed ad campaigns:
Video resolution: Min 1080 x 1080 pixels
Video formats: GIF, MP4 or MOV
Video size: 4GB
Video ratio: 4:5 for mobile users and 1:1 for desktop users
Clip length: Max 241 minutes
2. Facebook Carousel Ad Specs

Facebook carousel ads are among the most popular and trendy formats, widely considered a conversion magnet for ecommerce brands eager to drive website traffic. Carousel ads are a gallery of two to ten images, much like a product catalog to showcase best-selling options or even share user-generated content to foster brand loyalty. When setting up a carousel ad, selecting the right Facebook ad size is crucial to ensure campaign performance and success.
Advertisers can design their carousel ads with images, videos or both but each image or video must lead the user to a specific web page relevant to the visuals. For instance, if you’re showcasing products with images, the image should be linked to the product’s URL. These conversion-focused ads are incredibly versatile, and when curated strategically, they can supercharge user interaction and website traffic.
When optimizing the Facebook carousel ad specs, it’s important to focus on narrating a visually captivating brand story. You can use this ad format to highlight the specifications of a single product or service, or showcase multiple offerings with an enticing blend of images and videos.
At GCG Media, we strongly believe in striking a balance as you plan your carousel with a sequence of 10 cards. Be sure to complete the narrative without overwhelming your target audience with excessive images or videos that lack a clear CTA. Since the space offered within the carousel ad placement is quite confined, it’s crucial to pay close attention to the specific Facebook ad size.
These ads can be placed at multiple placements, including Feed, Stories, Marketplace, Reels, Search results, Audience Network and even Business Explore.
If you’re setting up a carousel ad in Facebook Reels, you’ll have to choose between two types: catalog product carousel and overlay carousel.
Catalog Product Carousel
A catalog product carousel features up to 10 images with a specific URL to lead users toward a web page. These ads appear at the bottom of the screen, highly recommended for ecommerce brands seeking to convert users who enjoy watching reels.
Overlay Carousel Ads
Brands can manually insert these ads into their own Facebook reels, or use the Advantage+ placements to automate the distribution process through the Meta advertising space. These carousels allow up to 10 images or videos that appear at the bottom of the screen.
Now that we’ve covered the basics, let’s take a look the Facebook carousel ad specs:
Number of Cards: 2 to 10
File size: Max 4 MB for videos; 30 MB for images
Image size: 600 x 600 pixels Max
Image ratio: 1:9:1 to 1:1
Image file: JPG and PNG
Video size: 120 x 120 pixels Max
Resolution: Min 1080 x 1080 pixels
Video file: GIF, MP4 and MOV
Clip duration: 1 second to 240 minutes
Once you’ve covered the Facebook carousel ad specs and chosen the right Facebook ad size, it’s crucial to dedicate your attention toward text and headline. Don’t exceed the character limit for Facebook ad headlines and text for each card in order to create a compelling narrative with a seamless flow. Complying with the Meta ad specs will ensure cohesion across all your ads, maintaining brand consistency in the messaging.
3. Facebook Ad sizes for the Right Column

Another popular ad placement to know before running Facebook ads, Its important to note that Facebook right column ads are designed for desktop users who access the platform through laptops or PCs. The Facebook ad dimensions for right column ads are mostly similar to those of feed and carousel ads.
Here are the Facebook ad sizes for right column placement:
Image file size: Max 30 MB
Image ratio: 1:1
Image size: 600 x 600 pixels Max
Image file type: JPG or PNG
Video file size: 4 MB Max
Video file type: GIF, MP4 and MOV
Video size: 120 x 120 pixels Max
Video resolution: Min 1080 x 1080 pixels
As you optimize the Facebook ad dimensions for right column ads, be sure to pay attention to the character limits. These ads don’t offer any space for additional copy. It’s wise to keep the messaging crisp and clear and within 40 characters. For this ad placement, headline and ad copy demands strategic planning, given the word count restrictions.
We suggest A/B testing your headlines to find the best-performing headline that grabs attention.
4. Facebook Ad Dimensions for In-Stream Videos

Advertisers often neglect Facebook video ad specs while setting up in-stream video ads – a mistake that disrupts the user experience, resulting in annoyance and frustration for the audience. These ads have the same format as carousel video ads but they appear when the user is watching a Facebook Live stream.
These ads are designed specifically for smartphone users, and advertisers can select up to 10 videos with a maximum duration of 10 minutes.
Here are the Facebook video ad specs for in-stream ads:
File size: 4 GB Max
Resolution: Min 1080 x 1080 pixels
Ratio: 1:1
File type: MP4 or MOV
Clip duration: 5 seconds to 10 minutes
Fixed frame rate: 30fps
In order to make the ad interactive and compelling, it’s wise to ensure the clips are no longer than 15 seconds. Keep the 125-character ad copy short and straightforward, while the 40-character headline should be attention-grabbing.
5. Facebook Ad Specs for the Marketplace

Brands that neglect Facebook Marketplace ads aren’t taking advantage of Meta’s specialized version of Craigslist where buyers and sellers come to advertise and explore products for sale. Facebook Marketplace is a cutting-edge innovation that offers free listings for brands, creators, advertisers and users looking to sell products.
Advertisers and brands have much to gain by allocating a specific portion of their advertising budget to Facebook Marketplace ads. These ads share the same Facebook ad size requirements as in-stream video ads, and the guidelines for the ad copy are also similar. Advertisers can create a combination of videos and images or stick to one format, depending on their campaign design and objectives.
Here are the Facebook ad specs for Marketplace ads:
Display size: Min 1080 x 1080 pixels
File type: JPG or PNG
File size: 30 MB Max
Ratio: 1:1
When designing a Marketplace ad, it’s important to ensure the ad revolves around the best-selling products, highlighting special features and driving attention towards a compelling CTA. Since the character requirement is limited, it’s wise to avoid adding too much text as the goal is to make sure your product grabs attention.
Instead of focusing on the ad copy, dedicate more attention to ensure the image stands out and captures user attention. Create an enticing combination of colors to accentuate visual appeal, and design the product photo with evocative hues to ensure your ad looks strikingly different from the organic listings.
