For organic posts, 1080 x 1350 pixels (4:5) is the best-performing feed
size in 2026. It takes up more of the mobile screen without cropping on
desktop. Square format (1:1, 1080 x 1080 pixels) still works everywhere and is the foolproof choice.

For Meta ads, the same two sizes apply: 1080 x 1350 for feed placements,
1080 x 1080 when one file has to work across every placement.

Facebook Stories and Reels — organic or paid — are 1080 x 1920 (9:16). 1080 x 1080 pixels. The size of a Facebook Story ad is 1080 x 1920 pixels.

However, there is more to know about Facebook ad specs and size. For example, how to design your Facebook ads to get more clicks? Or what Meta ad sizes to create for maximum success?

Also, when advertising on Facebook, you’ll have the option to use more than one ad type.

In fact, there are currently ten different Facebook ad formats (not counting Instagram ads), each perfect for some kind of Facebook ad campaign structure. It is super helpful to know about all the seven ad layouts and when to use them.

In this guide, we’ll touch upon the following questions:

• What’s the right Facebook ad size?
• What’s the best Facebook feed post size?
• What are all the different Facebook ad types?
• What are all the Facebook ad specs?
• What are some of the best examples of Facebook ads?
• How and when to use particular ad types?

Let’s begin with the basics: the dimensions for Facebook feed posts and news feed ads. And then move on to more advanced Facebook banner sizes.

But first, a question that 90% of the articles listing the ad sizes do not cover: How to select the right ad types and sizes when creating your Facebook campaigns?

Facebook post sizes in 2026 (organic posts)

Facebook has quietly shifted toward vertical. 4:5 (1080 x 1350) is now the best-performing feed size because it takes up more of the mobile screen without getting cropped on desktop.

Square format still works, however, and is the safest single export if you only make one.

How to select the right Facebook size for each ad type?

If you’re just getting started with Facebook advertising, you’re likely to need some help with picking the correct ad dimensions.

After all, there are MANY possible placements…

After seeing such a wide variety of options, it is easy to get confused…

Also, back in 2018, the go-to Facebook ad size used to be 1200 x 628 pixels. Now, you can publish Facebook posts that 1080 x 1080 pixels wide or portrait: 1080 x 1350 pixels. This means a lot more real estate in the news feed.

For example, compare these two ads:

❗ 2025 UPDATE! All Facebook feed ad placements are now eligible for the 1:1 format ad sizes, so you don’t need to upload a landscape ad format anymore.

When creating a new Facebook ad campaign, we recommend using Automatic Placements for maximum reach.

This means that you will need to create ads in at least 2 formats:

• 1080 x 1080 pixels for Facebook and Instagram news feeds
• 1080 x 1920 pixels for Facebook and Instagram Stories

You can upload images with different dimensions under a single ad by selecting “Select a placement to customize” when editing your Meta ads.

Below is an example of the static image ad types we use in a MeetFrank ad campaign. We used the three banner sizes listed above.

What happens if you do not upload some of the special Meta ad sizes?

If you don’t have time or resources to create custom image sizes for Instagram ads, you can also use the 1:1 format ads and Facebook will automatically adjust your creative for the Story placements.

Not adding a custom ad image for the Story placement can result in slightly less good-looking ads. But you can still run them and get ok results.

Here’s the difference:

To sum this up, you can follow these three best practices:

• Use as many Facebook ad placements as possible for maximum reach.
• Upload custom image and video sizes for all the placements you’d like to use.
• If you don’t have time to create all image sizes, just go with the 1080 xs 1080px ad size.

When publishing Facebook posts, you can also use images 1080 xs 1080 pixels wide.

Alright… Let’s now take a look at the Facebook ad specs for all the available ad types, so that you can create high-performance ad creatives.

Facebook ad sizes and formats in 2026

When creating Meta ads for my own managed ad accounts, I always export static image ads at PNG files. JPGs are ok as well, but may deliver slightly lower quality in the final result seen by your audience.

Design at 1080 x 1080 and 1080 x 1920 and you’re covered for roughly 90% of Meta ad delivery.

Here’s the full spec sheet, with the ones that matter marked.

Facebook Audience Network ad specs

The Facebook Audience Network allows you to extend your Facebook and Instagram campaigns across the internet – and to have your ads shown on thousands of high-quality websites and apps.

In a Facebook ad campaign study, the conversion rates and results were 8x higher among people who saw ads across Facebook, Instagram and Audience Network than people who only saw the ads on Facebook.

So it usually makes sense to include the Audience Network placement in your ad campaigns. If possible, also add video creatives into your ad campaigns as many Audience Network placements only show video ads.

Facebook Marketplace ad creatives

Facebook Marketplace is a place on Facebook’s platform where users can buy and sell items. As they browse around, they will also spot some ads in the feed.

We wouldn’t recommend using Marketplace as the only placement in your ad campaign as the potential reach would be fairly low.

However, if you already have ad images in 1:1 format for other placements (e..g for the Audience Network), you can also add the Marketplace placements for additional reach.

When advertising on Instagram, you’ll have an option to use more than one ad type.

In fact, there are currently seven different Instagram ad types, each perfect for a slightly different marketing campaign. (That’s still a lot less than Facebook ad types though.)

It is highly important that you’re aware of all the seven ad layouts and know how to use them. You do want to get the highest possible ROI out of Instagram advertising, right?

In this chapter of the Instagram Advertising Guide, we’ll touch upon the following questions:

• What are all the different Instagram ad types?
• How to set up each ad type?
• What’s the right Instagram ad size?
• What are all the Instagram ad specs?
• What are some of the best examples of Instagram ads?
• How and when to use particular ad types?

We’ll start with the most popular Instagram ad sizes and move on to the more specific ones used by advanced marketers.

Instagram Ad Specs & Sizes 2026: Feed, Story, Reels

Three files cover every Instagram placement that matters: 1080 x 1350 for feed,
1080 x 1920 for Stories and Reels, and 1080 x 1080 for carousel cards.

The Instagram Feed has moved from 1:1 to 4:5 as the default, it claims more of the screen than a square ad.

Master table:

File limits:

Images: JPG or PNG, up to 30 MB. Video: MP4 or MOV, H.264 codec with AAC audio, up to 4 GB. Carousels: 2 cards minimum, 10 maximum — and every card must be the same size.

1. Single Image Ads

The most widely used ad type for both Instagram and Facebook advertising is the Single Image Ad.

This ad type consists of an image, ad copy, and a call-to-action button. The Instagram image size can vary depending on the size of your uploaded photo.

Check out this article with 84 Instagram ad examples for additional inspiration.

This popular ad type can be applied to all kinds of advertising offers as you can use many different types of images and offers inside the Single Image Ad format. Moreover, as you promote a blog article or other types of content on Instagram, you’ll be using the Single Image Ad layout as well.

Different Instagram ad sizes

Single Image Instagram Ad specs:

• Caption: up to 125 characters
• Media type: image
• Recommended image size: 1080 x 1080 pixels
• Image format: .jpg or .png

2. Instagram Carousel Ads

Carousel ads allow you to showcase up to 10 images or videos (named cards) inside a single ad.

You can recognize a Carousel Ad by the small dots under the image, indicating that there is more than one image to be seen.

Instagram Carousel Ads are a bit trickier to compile than Single Image Ads. But these ads provide an excellent opportunity to:

• To create a step-by-step illustration of how to use your product
• Tell a story about your brand in several images or videos
• Give a good sense of the essence of your promoted offer
• Lower your Instagram ads cost

Tip: When setting up Carousel Ads for Instagram, you don’t need to fill in the Description, See More URL and See More Display URL fields. These are only required for Facebook Carousel Ads.

Instagram Carousel Ad specs:

Video Ads let you introduce your offer with a video or GIF.

The video ads are a great way to explain how your product works or simply share a fun and engaging message about your brand.

Moreover, video ads’ moving nature helps to better catch people’s attention as they scroll their Instagram feeds.

In 2017, Facebook also added an update that allows advertisers to use GIF-format videos in their ads.

Example of an Instagram video ad

Now, brands also have a chance to appear in people’s Instagram Stories feed. You can create Image Stories Ads that contain up to six images to tell your brand’s story in a fun and engaging way.

To collect inspiration from the best Instagram advertisers in 2021, see this showcase of 40 Instagram Story Ad Examples.

It’s an amazingly engaging way of showcasing your product, building your brand’s personality, and engaging your audiences by reminding them of your offers.

• Recommended Video Codecs: h.264, VP8
• Recommended Audio Codecs: AAC, Vorbis

Remember that you can set up your Instagram ads in the Facebook Ads Manager. There is no Instagram-only tool for creating your ad campaigns.

I recommend that you test multiple Instagram ad types and sizes to uncover which ones are most liked by your Instagram target audience and bring the best results.

Safe zones: where not to put your text

Instagram Story and Reels ad placements overlay your creative with interface elements, and anything you place underneath them disappears.

Keep text, logos, and anything you need read out of roughly the top 250px
(profile bar) and bottom 340px (CTA and caption area). That leaves you about
1,330px of usable height on a 1920px canvas.

Design for the safe area, not to the full frame.

For feed carousels, the caption crops after roughly two lines on mobile, so
whatever matters goes in the first sentence.

Now, head on to the next chapter to learn about the top Instagram ad design and copywriting hacks.
