Facebook Ad Image Best Practices: A Go-To Guide

Why Does Facebook Ad Size Matter For Your Clients?

Picture this: your agency’s graphic design department spent hours creating the perfect ad image for a client’s upcoming social media campaign. It’s so brilliant and aesthetically pleasing that you even look forward to hitting that “Like” button when those sponsored ads pop up on your feed.

To your shock and horror, you realize that the ad size wasn’t optimized and a cropped Instagram story with black bars shows up instead. To top it off, the “Learn More” call-to-action button has completely covered the most amazing part of the ad image that took your designer many hours and cups of coffee to complete.

What a marketing nightmare! Don’t let it happen to you (and, most importantly, to your clients). 

People have extremely short attention spans on social media. You have a fraction of a second to grab their attention so they even read your ad.

- Guy Hudson, Vice President of Digital Marketing at We Are Marketable

So, if you’re a marketing agency looking for a quick cheat sheet of Facebook ad sizes, you’ve come to the right place *bookmarks for later*. 

It’s time-consuming to constantly search for multiple Facebook ad sizes, especially when you’re tasked with repurposing social media content and a million other things. It can get a bit sticky managing your agency’s output and resources while also optimizing your clients’ Facebook ads – we get it.

But, as Alex Kutschukian, Managing Director and Co-Founder of Red Herring Digital, points out, “Media placement plays an important role in how consumers engage and interact with Facebook Ads. Ask yourself, where is this ad being seen? Feed, story, display, video, and the list goes on. From an advertising perspective, you want to ensure your creative takes up as much screen as possible to increase the likeliness of your ad being noticed.”

Depending on your client's goal, you’ll also find variations in social media strategies or even the appropriate use of specific ad types. While a carousel ad may work well for one client, a video ad may do the trick for another.

Equipping your agency with the necessary knowledge of best practices can create Facebook ad images that make your clients jump for ROI joy! 

Design Tips To Optimize Facebook Ads

First impressions are lasting ones, especially when it comes to the design of Facebook image ads. It isn't only about sourcing the best stock or product photo. 

“The audience is being bombarded with advertising both on and off Facebook,” says Ramsey Sweis, President and Founder of Aqaba Technologies. “So it is important to capture your audience's attention within 3 seconds. Not being able to connect with your target audience instantly will not deliver any results worth discussing.”

As an advertiser, it means you’ve got a very short window to capture your audience’s attention and really drive your message home.

Here are a few quick design tips to optimize your client’s Facebook ads:  

1. Simple, Effective, and Streamlined Messaging

It may be tempting to pack as much information as possible within your client’s Facebook ad, but you may end up losing your audience in the process. Integrating visually aesthetic text that’s to the point will increase the chances of your audience favorably responding to your client’s Facebook ad. 

Alex Kutschukian says that it is imperative for advertisers to use and test a variety of content because “audiences for different types of businesses respond differently to different types of content.”

He advises experimenting with mixed media like images with graphics or a series of images turned into a video. “Long story short, images are KEY to killer ads!” he adds. 

While Facebook’s 20% text rule is no longer mandatory, it’s still recommended and is generally a good rule of thumb to ensure Facebook ad images aren’t too text-heavy or visually unappealing.

2. Use Colors Effectively

It’s ideal to mirror your client’s brand collateral and aesthetics when designing their Facebook ads. Whether you choose to go with a monochromatic, complementary, or triple color scheme, an effective color palette can work to optimize your client’s Facebook ads and social media presence. 

3. Make Ads Relevant to the User 

As an agency, you know the importance of having demographic profiles as your first research tactic before ad creative is even developed.

Facebook ads are no different, and it’s important to use imagery that appeals to your audience. After all, an ad that appeals to your client’s audience increases the likelihood of a positive return on ad spend, which will keep them coming back for your agency’s services.

"Images are the first impression a client or customer receives for your business," notes Stephanie Henshaw, Social Media Manager at Marwick Marketing. "One strong, captivating image can mean the difference between customers reading the rest of your ad or not."

This can include images of people that fall within your demographic profiles with distinct characteristics related to occupation, lifestyle, or any other appropriate references for your client’s Facebook ad. 

4. Use Full-Sized High-Resolution Images

There’s nothing more basic than a blurry Facebook ad image or something so small you can’t tell what it is.

It’s no surprise that Facebook’s minimum resolution for image ads is 1080x1080 pixels- and for good reason. The last thing you want is to compromise your client’s brand reputation or quality because of low-resolution imagery.

“If this image is too small, it doesn't get enough attention. If it's larger, we can typically fit more picture/message on it at once,” suggests Nathan Hawkes, President and Founder of Arcane Marketing. “The more the image can show, the better of a story it tells, and the more engagement we get.”

High-quality imagery:

• Represents your client’s business

• Builds your client’s brand credibility

• Gives a compelling brand narrative

• Creates the visual messaging for a client’s brand

Whether it’s a static image, carousel ad, or video ad, high-resolution files are the way to go.

“Square and portrait images take up more screen real estate, particularly on mobile devices, than a landscape image,” adds Tyron Zeelie, Head of Social at Sprocket Digital. “This slight advantage increases the chances of a prospect seeing and clicking your ad.”

5. Optimize Designs for Mobile Placements

An astounding 81.8% of users access Facebook only through a mobile device, so your client’s Facebook ads should always be designed to fit this placement. 

“Images are displayed differently across different devices,” says Tyson Downs, Owner of Titan Web Agency. “For your ad to render correctly on mobile and desktop devices, it is necessary to stick to the specific size requirements for your visuals. Sizing that doesn't fit could cut off important messaging on your marketing material, affecting campaign performance.”

There’s nothing worse than setting up a Facebook campaign and realizing that the incorrect ad sizes were used. Resizing images may require some extra effort, but it’s always worth it, especially when it comes to having impactful Facebook ads for your clients. 

6. The Best Marketing Is Emotional

You know all too well that marketing is heavily based on understanding your consumer's emotions and their pain points. Creating effective Facebook ad images is no different. By intricately understanding your clients’ customer base and what they’re searching for, you develop ads that address their concerns and generate interest in your client’s brand.

After all, it won’t make much sense to have an aesthetically-designed ad that’s mostly fluff and doesn’t actually accomplish what it’s supposed to do.

This can involve using emotive words or imagery that tap into their aspirations or goals.

“Images grab attention and have as much to do with conveying the message of the ads as text,” adds Drew Hanson, Digital Advertising Manager at PaperStreet. 

By putting yourself in your audience’s shoes, you will better understand their pain points and market to them meaningfully.

7. A/B Test To Find the Best Images

As an agency, you’re likely overflowing with creative concepts and strategies, especially when developing ad images. A/B testing is an excellent way to compare the performance of two ad images with one variable element to see what resonates with your client’s audience.

If you do A/B testing across multiple client ads, you may even be able to observe general trends for the best types of ad images and elements. As Ramsey Sweis puts it, “We perform variant testing on all of our campaigns. The best performing ads we have found had exaggerated taglines and legible graphics.”

Implementing this step will show your clients that you’ve done your due diligence and help you make a data-informed decision on your creative output. 

“Testing is crucial. If you ever were unsure about which image size will work best for your audience, run the different-sized images, with the same ad campaign and to the same audience on a low budget for a few days. This will give you the data you need on which image size is most engaging for that audience.”

- Guy Hudson

While A/B testing provides valuable insights on a design element related to your ad image, it also has drawbacks. For example, you may not necessarily have insight into why users prefer one design over the next. Also, Facebook's data restrictions make it very difficult to see the variation in performance at the image level unless you create dedicated ad sets just to test an image.

And when A/B testing is done with only one variant between ad images, it can become challenging and time-consuming to test the impact of other design elements.

To work around this, implement other methods of data collection that directly get user feedback, such as engaging polls or surveys. Facebook’s robust algorithm can also help you to decide on the best ad image, but it’s always best to get more insight into user perception.

Facebook Ad Sizes That Every Agency Should Know

Choosing an appropriate Facebook ad type, aspect ratio, and image size may seem daunting, but it doesn’t have to be. 

After deciding on your client’s social media strategy, it’s important to evaluate what images are available to use. You may have an abundance of social media collateral at your fingertips (such as stock photography or an extensive bank of unique images from your client). 

“Compelling images catch the eye of someone who's scrolling through their feed, grabbing their attention long enough to read the ad headline.”

- David Sanchez, CEO & Founder,  Digitalis Medical

On the other hand, you may be presented with a situation where ad images are limited (such as a modest number of photos from your client or even a small number of available stock images for a niche product).

Regardless of the scenario, there are many options to choose from when showcasing your clients’ services or products through Facebook ads.

Image Ad Specs

As the name suggests, image ads are static visuals shown across various parts of Facebook, such as the feed or even on the sidebar when the platform is accessed via a desktop computer. 

Depending on your goal or the settings you choose, these static image ads can appear in various places within the platform. Facebook recommends JPG or PNG file types for all image ad placements with a resolution of at least 1080x1080 pixels and a maximum file size of 30MB. There’s one exception for audience network image ads which should have a minimum resolution of 398 x 208 pixels. 

Here are the most popular ad placements and specifications that you should know for Facebook image ads, along with some examples courtesy of Facebook:

1. Facebook Feed

• Primary Text Length: Up to 125 characters

• Description: Up to 27 characters

• Headline: Up to 27 characters

• Height: At least 600 pixels

As the name suggests, these Facebook ads pop up when a user scrolls through their feed (and yes - we also had a hard time not saying “News Feed” since Facebook rebranded this term back in February). 

It’s usually coupled with a call to action, such as clicking a website link or filling out a lead generation form (depending on what goal this Facebook ad is optimized for).

Another neat option is utilizing a panoramic 360-degree image ad which is an excellent option for showcasing a client’s physical store or event.

2. Facebook and Instagram Stories

• Aspect Ratio: 9:16

• Primary Text Length: Up to 125 characters

• Width: At least 254 pixels

Keep in mind that once this option is utilized, Facebook turns off all other ad placements.
