Facebook Ads Image Size Specifications: Mastering Feed, Carousel, and Story

Facebook Ads image size specifications are a crucial part of creating high-performing ad campaigns. In this article, I’ll walk you through the three most-used ad formats: Feed Ads, Carousel Ads, and Story Ads. If you're running Facebook campaigns, you need to know how image sizes impact ad delivery and results. Keep reading and make sure your ads show up sharp, clean, and on point.

Facebook Feed Ads: Sizes and Best Practices

What’s the recommended size for Facebook Feed Ads?

The ideal image size is 1080 x 1350 pixels. You can use aspect ratios from 1.91:1 to 1:1, but 1:1 is the most balanced for mobile and desktop.

Facebook Feed Ads appear in users' scrolling timelines. If your image is too wide or too tall, Facebook will crop it. That means part of your message might disappear. Worse, it could look unprofessional.

You should also:

• Use JPG or PNG

• Keep file size under 30MB

• Use minimal text (no more than 20% of the image)

To get better results, focus on high contrast visuals. Choose bright colors that catch the eye. And always test square images vs. vertical to see what works for your audience.

Pro tip:

Avoid putting key info (like text or logos) near the edges. Facebook might trim them in previews.

Carousel Ads: How to Design for Swipes

Carousel Ads let you showcase up to 10 images or videos in one ad, each with its own link.

Recommended size:

• 1080 x 1080 pixels

• Aspect Ratio: 1:1

Each carousel card must tell its own story but still feel like part of the whole. Keep fonts, colors, and layout consistent across all cards.

Why is image size important here?

Because Facebook shows all your carousel images in a horizontal swipe. If one image is blurry or cropped wrong, it breaks the flow and confuses viewers.

Best practices:

• Use high-resolution images (300dpi if possible)

• Keep text short and readable on mobile

• Use visual sequencing (like a step-by-step or before-and-after)

Pro tip:

Start your first card with the most engaging image to grab attention. It sets the tone for the rest.

Story Ads: Fullscreen Impact

Facebook Story Ads take up the whole screen on mobile, so the image format needs to be precise.

Ideal size:

• 1080 x 1920 pixels

• Aspect Ratio: 9:16

If you use square or landscape images, they’ll appear smaller or have black bars around them. That’s wasted space and lost impact.

When you design for stories:

• Place text and logos within the “safe zone” (center 1080 x 1420 px)

• Use bold, readable fonts

• Add motion (GIFs or subtle animation) for attention

Story Ads disappear in 24 hours. That gives them urgency, but also a short window to work. Make sure every pixel counts.

Pro tip:

Use video thumbnails or animated images to boost click rates.
