If your static Facebook or Instagram ads are not getting the reach you expected, the problem may not be your creative or targeting. It could simply be your Meta Ad Size.
Meta has started recommending a 4:5 aspect ratio for most static image ads because it takes up more space in the mobile feed. Since most people scroll Facebook and Instagram on their phones, this small change can make your ad more noticeable and help improve performance.
Many beginners still create square (1:1) images because that has been the standard for years. While square images still work, Meta now recommends using 4:5 for many feed placements. A larger image can catch attention faster and encourage people to stop scrolling.
In this guide, you’ll learn what the new Ad Size recommendation means, why it matters, how to create better ads, and how to update your existing campaigns without starting from scratch.
What Is this?
It means the dimensions and aspect ratio of the images or videos you upload for Facebook and Instagram ads.
Choosing the right Meta Ad Size helps your creative look clean, professional, and easy to read. If your image is too small or uses the wrong ratio, important parts may be cropped or hidden in different placements.
Meta supports several image sizes, but each placement works best with a specific format. That is why using the recommended Meta Ad Size can improve how your ad appears across Facebook, Instagram, and other Meta platforms.
Why Did Meta Change the Recommended Meta Ad Size?
Most people now use Facebook and Instagram on mobile devices. Mobile screens are taller than they are wide, so taller images naturally take up more screen space.
The new Meta Ad Size recommendation of 4:5 allows advertisers to show a larger image without forcing users to rotate their phones.
When your ad covers more of the screen, people notice it more easily while scrolling. Even though Meta has not guaranteed higher conversions, better visibility often gives your creative a better chance to earn clicks, engagement, and sales.
Instead of focusing only on making beautiful designs, Meta wants advertisers to create ads that fit naturally into today’s mobile experience.
What Is the New 4:5 Meta Ad Size?
The recommended Size for static feed images is now 4:5.
The most common dimensions are:
- 1080 × 1350 pixels
- Aspect Ratio: 4:5
This format is taller than the traditional square image.
A taller Ad Size fills more of the mobile screen, making it easier for users to notice your message before they continue scrolling.
If you’re creating new static image ads, starting with the 4:5 format is one of the easiest improvements you can make.
Benefits of Using the New Ad Size
Changing your Meta Ad Size may seem like a small update, but it can bring several benefits.
1. More Screen Space
The biggest advantage is that your image becomes larger in the mobile feed.
Instead of competing with many posts around it, your ad gets more room to stand out.
2. Better Attention
People scroll social media very quickly.
A taller Meta Ad Size naturally catches the eye because it occupies more space than a square image.
More attention gives your headline and product a better chance to be noticed.
3. Better User Experience
The 4:5 format fits naturally inside Facebook and Instagram feeds.
Users don’t need to zoom in or struggle to read your message.
Everything appears cleaner and easier to understand.
4. More Room for Your Design
With the new Meta Ad Size, you have extra vertical space.
This allows you to include:
- Product images
- Short headlines
- Brand logo
- Call-to-action
- Simple background graphics
Without making the design feel crowded.
5. Works Well for Beginners
Many new advertisers think they need advanced editing skills.
The truth is that simply choosing the correct Meta Ad Size already improves how your ad looks.
Even a simple design can perform well when it follows Meta’s recommended format.
4:5 vs 1:1 Ad Size
Let’s compare the two formats.
| Feature | 1:1 Square | 4:5 Vertical |
|---|---|---|
| Feed Space | Smaller | Larger |
| Mobile Visibility | Good | Better |
| Product Display | Limited | More Space |
| Text Placement | Limited | Flexible |
| Recommended by Meta | Still Supported | Recommended for Static Feed Ads |
The square format is not outdated.
However, the newer Meta Ad Size gives advertisers a better opportunity to grab attention on mobile devices.
If your campaign mainly targets mobile users, using 4:5 is usually the smarter choice.
Best Image Dimensions
Here are some common image sizes you should know.
| Placement | Recommended Meta Ad Size |
|---|---|
| Facebook Feed | 1080 × 1350 px |
| Instagram Feed | 1080 × 1350 px |
| Square Feed | 1080 × 1080 px |
| Stories | 1080 × 1920 px |
| Reels | 1080 × 1920 px |
Creating your images in these recommended Ad Size dimensions helps your ads display correctly across different placements.
Which Placements Support the New Meta Ad Size?
The new Ad Size works especially well for:
- Facebook Feed
- Instagram Feed
- Facebook Video Feed
- Instagram Explore Feed
These placements are where most users spend their time scrolling.
Using the correct Ad Size allows your creative to appear larger without reducing image quality.
How to Change Your Existing Ads to the New Ad Size
If you already have ads running, you do not need to build everything again. You can update your images to the new Meta Ad Size in just a few simple steps.
Step 1: Open Ads Manager
Go to your Meta Ads Manager and choose the campaign you want to improve.
Step 2: Check Your Current Image
See whether your image is using the old square format (1:1) or another aspect ratio.
If your image is already 4:5, you are ready to move on.
Step 3: Create a New 4:5 Image
Use a design tool like Canva, Photoshop, or any image editor.
Set your canvas to:
- 1080 × 1350 pixels
- 4:5 aspect ratio
This is the recommended Meta Ad Size for static feed ads.
Step 4: Keep Important Content in the Center
Leave some space around your text, logo, and product.
Different placements may crop your image slightly, so avoid placing important details too close to the edges.
Step 5: Upload the New Image
Replace the old image with your new 4:5 version.
Preview your ad before publishing to make sure everything looks good across different placements.
Design Tips for the Best Meta Ad Size
Choosing the correct Meta Ad Size is only one part of creating a successful ad. Your design also needs to be simple and easy to understand.
Use One Main Message
Do not try to explain everything in one image.
Focus on one product, one offer, or one benefit.
Keep Text Short
People scroll quickly.
Use short headlines that are easy to read in just a few seconds.
Use High-Quality Images
Blurry or low-quality images make your business look less professional.
Always upload clear images with good lighting.
Add Your Brand Logo
Including your logo helps people remember your business.
Place it where it is visible but does not cover the main image.
Use Strong Contrast
Choose text colors that are easy to read against the background.
For example, white text on a dark background or dark text on a light background usually works well.
Common Mistakes to Avoid
Many beginners make simple mistakes when creating ads.
Avoid these problems to get the most from the new Meta Ad Size.
Using Low-Resolution Images
A stretched image can look blurry and reduce trust.
Always design your images in the correct dimensions.
Adding Too Much Text
Your image should support your message, not become a long article.
Keep your design clean and simple.
Ignoring Mobile Users
Most people see your ads on smartphones.
Always preview your Meta Ad Size on mobile before publishing.
Copying One Design Everywhere
Different placements have different layouts.
Although the 4:5 Meta Ad Size works well in feeds, Stories and Reels use a 9:16 format.
Always check how your creative appears in each placement.
Forgetting to Test
Never assume your first design is the best.
Create two or three versions using the same Meta Ad Size and compare their results.
Even small changes to colors, headlines, or images can improve performance.
Does the New Meta Ad Size Guarantee Better Results?
No.
Using the recommended Meta Ad Size does not automatically increase sales or conversions.
Your results still depend on several factors, including:
- Your audience targeting
- The quality of your offer
- Your ad copy
- Your creative design
- Your landing page
- Your campaign objective
However, the correct Meta Ad Size gives your ad a better chance to grab attention because it takes up more space in the mobile feed.
Think of it as giving your ad a stronger first impression.
Is It Worth Updating Old Ads?
Yes, especially if your ads mainly appear in Facebook and Instagram feeds.
Updating your creative to the latest Meta Ad Size is a small change that can improve how your ads look on mobile devices.
You do not need to redesign your entire campaign.
Often, resizing your image and adjusting the layout is enough to match Meta’s latest recommendation.
This makes your ads feel more modern while giving users a better viewing experience.
