Meta Ad Image Sizes & Specs 2026

By Corey Frankosky · Last Updated August 6, 2026

Getting the Meta ad image sizes right is one of the easiest ways to make your Facebook and Instagram ads look professional instead of blurry or cropped. Meta scales your creative to fit each placement, so when you upload the wrong dimensions, the platform crops your subject, squeezes your headline, or renders your image soft on modern phone screens. This guide gives you the exact resolutions, aspect ratios, and file requirements for every major placement in 2026, along with the safe zones and character limits that keep your message visible. Use it as a checklist before you export a single file.

1Meta ad image sizes at a glance

Every Meta placement pulls from the same creative, but each one displays it differently. The table below lists the resolution you should upload, the aspect ratio the placement uses, the minimum size Meta accepts, and the file rules. Upload the highest resolution version you have inside the correct aspect ratio. That gives Meta room to render your ad sharply on high-density phone screens instead of forcing it to stretch a small file.

One detail worth knowing: Meta allows a small amount of aspect ratio variance before it crops or rejects a file. Facebook placements permit roughly a 3% variance, while the Instagram Feed is stricter and holds closer to 1%. Export to the exact ratio so you are never at the mercy of that tolerance.

Question to Answer:

Do you know which single placement drives the most impressions on your account, and are you exporting your creative to match its exact aspect ratio?

2Feed image ads (1:1 and 4:5)

The Feed is where most of your budget gets spent, so start here. You have two strong options: the 1:1 square at 1440 x 1440 pixels and the 4:5 vertical at 1440 x 1800 pixels. The 4:5 vertical is usually the better choice on mobile because it takes up more vertical space in the scroll, which keeps your ad on screen longer. If a large share of your traffic is on desktop, the 1:1 square holds up well there and looks consistent across both platforms.

Watch your copy length so nothing gets cut off. Keep your primary text in the range of 50 to 150 characters and hold your headline to about 27 characters before it truncates on mobile. Export as JPG or PNG under 30 MB. Meta accepts a minimum of 600 x 600 pixels, but that is a floor, not a target. Uploading at 1440 pixels on the long edge keeps the image crisp on retina displays.

Question to Answer:

Are your current Feed ads running at 1440 pixels on the long edge, or are you still uploading the old 1080 x 1080 files?

3Stories and Reels ads (9:16)

Stories and Reels are full-screen placements, so you want a 9:16 vertical asset at 1440 x 2560 pixels. Anything smaller than the full canvas leaves black bars or forces Meta to scale your image up, and both look cheap in a format built for edge-to-edge video and photos.

The bigger issue in these placements is the interface. Meta layers its own elements over your creative: your profile name and handle near the top, and comment icons, audio controls, and the call-to-action near the bottom. If you place your logo, text, or offer in those zones, the platform covers them.

Design the creative full-bleed for the background, but treat that central area as the only place your message is guaranteed to show.

Question to Answer:

When you preview your Stories ad in Ads Manager, is any part of your headline or logo hidden behind Meta's interface?

4Carousel ads

Carousel ads let you show 2 to 10 swipeable cards in a single ad, which works well for multiple products, a step-by-step story, or one wide image split across several cards. Build every card at 1080 x 1080 pixels in a 1:1 square. Uniformity matters here. If one card is a different size or ratio, the set looks broken as the user swipes.

• Resolution: 1080 x 1080 pixels, 1:1 square, for every card.
• Card count: a minimum of 2 and a maximum of 10.
• Copy limits: keep each headline to about 45 characters and the primary text to about 80 characters per card.
• File size: each card must stay under 30 MB.

Question to Answer:

Is every card in your carousel the same 1:1 size, or is one odd file breaking the swipe?

5Collection ads

Collection ads pair a hero cover image with a grid of product thumbnails and open into an Instant Experience, a fast-loading mobile landing page inside the Meta app. Build both the hero cover and the supporting product images at 1080 x 1080 pixels in a 1:1 ratio so the cover and the catalog thumbnails feel like one set.

Keep your headline to around 40 characters and your primary text to around 125 characters. Because this format is built for mobile shopping, use clean product photography that reads well at thumbnail size.

Question to Answer:

Does your collection cover image visually connect with the products shown in the grid below it?

6Right column, Marketplace, and Messenger ads

These placements share the same square requirement but reach people in different contexts.

• Right column: a 1:1 square at 1200 x 1200 pixels. This placement only shows on desktop web browsers, so the image is smaller on screen and simple, high-contrast creative works best.
• Marketplace: a 1:1 square at 1200 x 1200 pixels. These ads appear on Facebook Marketplace next to listings, in front of people who are already in a shopping mindset on both mobile and desktop.
• Messenger inbox: a 1:1 square at 1200 x 1200 pixels, shown between conversations in the Messenger app.

You do not have to design these separately in most cases. A single well-built 1:1 square at 1200 pixels or larger covers all three.

Question to Answer:

Are you letting Meta place your ads in the right column and Marketplace, and does your square creative still read clearly at a small size?

7Audience Network ads

The Audience Network extends your Meta ads to third-party apps and websites outside of Facebook and Instagram. It uses two formats depending on where the ad shows. For native banner placements, use a 1.91:1 ratio at 1200 x 628 pixels. For interstitial, full-screen placements, use the 9:16 vertical you already built for Stories and Reels.

Because you do not control the exact apps your ad appears in, keep the creative simple and make sure your branding and offer are legible even when the image is scaled down.

Question to Answer:

If you run Audience Network placements, do you have both a 1.91:1 banner and a 9:16 vertical ready?

8Choosing the right file format

Meta compresses images after you upload them, so the format you choose affects how much quality survives. Match the format to the content of the creative.

• Use JPG for photography: lifestyle shots, gradients, and detailed backgrounds hold up best as JPG exported at 90 to 100% quality. That gives Meta a clean, high-quality file to compress from.
• Use PNG for text and logos: creative built around text overlays, vector logos, or sharp graphic edges stays crisp as a PNG. JPG compression tends to blur those hard edges.

Whichever format you pick, stay under the 30 MB limit and export at full resolution. Meta's own Business Help Center recommends using the highest resolution images available and treats the listed pixel dimensions as minimums, not targets.

Question to Answer:

Are you exporting text-heavy ads as PNG and photography as high-quality JPG, or using one format for everything?

9Testing aspect ratios and avoiding quality problems

Two habits keep your Meta creative sharp and improve results over time. First, do not upload the minimum. A 600 x 600 pixel square meets Meta's requirement, but it looks soft on a modern phone. Render square Feed assets at 1440 x 1440 pixels so they stay clean on retina screens, and remember the central 1080 x 1420 safe zone for anything you run in Stories.

Second, test the 1:1 square against the 4:5 vertical in the mobile Feed. The 4:5 format takes up more of the screen and often earns a higher click-through rate because it keeps your ad in view longer, but the only way to know what works for your audience is to run both and compare cost per result. Let the data decide instead of committing to one ratio out of habit.

Question to Answer:

Have you run a clean 1:1 versus 4:5 test in the Feed, or are you assuming one format wins?
