Meta Ad Aspect Ratios & Sizes by Placement

The short answer: four ratios, two masters

Meta serves your creative across a handful of surfaces, and each one wants a different shape. Rather than memorise a dozen pixel dimensions, hold onto four ratios and a production shortcut.

The four ratios that matter are 1:1 square, 4:5 vertical, 9:16 full-screen, and 1.91:1 landscape. Meta's 2026 Facebook Ads Guide now defaults the Feed image ad to 4:5 at a recommended 1440 x 1800 px. Stories and Reels default to 9:16 at 1440 x 2560 px. The square 1:1 is the natural shape for carousels and Marketplace, and the 1.91:1 landscape at 1200 x 628 px covers the classic right-column and link placements.

The shortcut is to build two masters. A 4:5 asset handles the Feed, and a 9:16 asset handles Stories and Reels. Those two shapes cover the majority of where your budget actually delivers. Add a 1:1 square when you run carousels, and a 1.91:1 landscape only if you deliberately buy right-column or link inventory. If you want the full breakdown by dimension, the companion guide on Facebook and Instagram ad sizes lists them placement by placement.

The placement-to-ratio cheat sheet

This table maps each common surface to the ratio Meta recommends or supports, with the recommended resolution to export at. Treat it as your starting point, then verify against Meta's ads guide before a big launch, because the recommended pixel values have crept upward over time.

The pattern is clear once you see it laid out. Vertical shapes win on mobile Feeds and full-screen surfaces, square is the carousel and Marketplace default, and landscape survives only in the older desktop and link slots. If you understand why Meta groups placements the way it does, the guide on Facebook ad placements explains how the delivery system chooses surfaces for you.

Feed: why 4:5 wins, and where 1:1 still fits

The Facebook and Instagram Feed is where most single-image and single-video budget lands, so getting this ratio right matters more than any other decision on this page. Meta's 2026 spec page for the Feed image ad recommends 4:5 at 1440 x 1800 px, with a minimum of 600 x 750 px and an aspect ratio tolerance of about 3%.

The reason 4:5 is now the default is simple screen real estate. A 4:5 vertical fills more of the phone as the reader thumbs past, which buys you a beat longer to land the message before the next post arrives. A 1:1 square is shorter and gives up some of that vertical space. Square is not wrong, and Meta still fully supports it, at a recommended 1440 x 1440 px (some sources still cite 1080 x 1080 px) with a 600 x 600 px minimum. It remains the right choice for carousel cards, where every card must be the same shape, and for Marketplace. But for a standalone Feed image, 4:5 is the shape to reach for.

There is a quiet production reason to master the taller shape rather than the square. A 4:5 crops down to 1:1 cleanly by trimming a little off the top and bottom, but a 1:1 cannot be stretched back up to 4:5 without adding empty bands or upscaling the pixels. That asymmetry means the 4:5 master gives you the square derivative for free, while a square master leaves you rebuilding if you later want the taller Feed shape. So if you will only invest your best photography and copy in one Feed file, invest it in the 4:5, then trim the square out of it when a carousel needs one.

Whatever ratio you choose, remember the Feed wraps your image in chrome: a header with your page name at the top and primary text plus a call-to-action below. Do not push critical words to the extreme top or bottom edge of a Feed asset, because the surrounding interface competes for that space. If you are weighing which format to run in the Feed at all, the choice between a carousel and a single image is a useful next question.

Stories and Reels: the 9:16 canvas

Stories and Reels share one canvas: full-screen vertical 9:16. Meta's 2026 ads guide recommends 1440 x 2560 px for image ads on both Instagram Reels and Facebook Stories, with a minimum width of 500 px and a tighter aspect ratio tolerance of about 1%. Shopify's 2026 guide corroborates the same 9:16 at 1440 x 2560 px, so this is a well-established target.

The tight 1% tolerance is worth internalising. On the Feed you have a little slack around the 4:5 shape, but full-screen placements want you very close to an exact 9:16. If you export a 9:16.5-ish frame, Meta will either reject the ratio or crop it, so set your canvas to a true 9:16 before you design. Whether you should build for Stories, for Reels, or both depends on how the two surfaces behave, since they differ in audience behaviour and in the pacing viewers expect.

The taller frame also carries a composition consequence that is easy to underestimate. A 9:16 canvas is far taller than a 4:5, so a layout that felt balanced in the Feed leaves awkward dead space if you simply drop it onto the full-screen canvas and centre it. Native 9:16 creative uses that height on purpose: a subject that fills the vertical, a background that runs edge to edge, and the message set into the band the interface leaves clear. Reusing a Feed layout unchanged is the single most common reason a full-screen ad looks like a repurposed square floating in a sea of empty pixels.

The full-screen canvas is the highest-impact surface you can design for, because nothing else on the screen competes with your creative. That is exactly why it is also the surface where a careless crop does the most damage, which brings us to the rule that decides whether your offer survives.

Safe zones: the rule that actually loses you sales

If you take one thing from this guide, take this. Meta's 2026 spec pages for both Instagram Reels and Facebook Stories say to keep text, logos and key elements clear of roughly the top 14%, the bottom 35%, and 6% of each side of the 9:16 frame. Two independent Meta spec pages state the same figures, so this is as authoritative as it gets.

Those regions are not arbitrary. The top 14% is where the profile name and timestamp sit. The bottom 35% is the busy zone: the caption, the call-to-action button, and the like, comment and share icons all stack up there. The 6% side margins account for the rounded edges and gesture areas of the interface. Put your price, your headline or your logo inside any of those bands and the platform's own UI will overlap it.

The bottom 35% is the one that catches almost everyone. Designers instinctively anchor a headline or a price to the lower third of the frame, which is precisely where Meta's overlay lands. Move your key message into the central band, roughly the middle half of the vertical frame, and it will read cleanly on every phone. The dedicated walkthrough on Meta ad safe zones shows this visually if you want a template to design against.

Here is a quick countdown to check any 9:16 asset before you upload it:

1. Is the logo out of the top 14%?
2. Is the price or headline out of the bottom 35%?
3. Is the call-to-action out of the bottom 35%, where Meta's own button sits?
4. Is anything critical within 6% of either side edge?
5. Does the middle band carry the message on its own if the rest is covered?

If all five pass, the creative will survive the crop and the overlay on any surface.

The 1.91:1 landscape and the right column

The 1.91:1 landscape ratio at 1200 x 628 px is the oldest shape in the Meta toolkit. It is the horizontal card you see in the desktop right column and in classic link ads. For advertisers running modern Advantage+ placements, it is a minor consideration, because so little budget flows to landscape-only inventory now. But if you specifically buy right-column or link placements, you need a landscape asset, and a 4:5 or 9:16 master will crop badly into that slot.

There is genuine ambiguity about the current right-column recommendation. One dated neutral source lists the right column as 1.91:1, while Shopify's 2026 guide lists it as 1:1 square. Because the two disagree, do not treat either as settled. Treat 1.91:1 as the dependable landscape and link ratio, and if right-column delivery matters to your plan, confirm the current recommendation directly in Ads Manager's placement selector or on Meta's ads guide before you export. This is a good example of why the ads guide, not any single third-party chart, is the source of truth.

File specs and tolerances that get ads cropped or rejected

Ratios decide the shape; file specs decide whether the upload is accepted. Across the image placements in Meta's 2026 ads guide, the rules are consistent: accepted file types are JPG and PNG, and the maximum file size is 30 MB. If a file exceeds 30 MB, compress it or drop the export quality slightly rather than shrinking the pixel dimensions below Meta's recommendations, because resolution is harder to recover than a few megabytes of compression.

The aspect ratio tolerance is the spec people miss. Feed allows roughly 3% deviation from the target ratio, while Stories and Reels allow only about 1%. That difference is why a frame that passes on the Feed can be flagged on a full-screen placement. Build your canvas to the exact target ratio and you never hit this wall.

One file-level choice quietly affects whether you stay under the 30 MB ceiling: JPG versus PNG. Both are accepted on every image placement, but PNG carries more weight for the same picture, so for photographic creative a JPG almost always keeps you below the limit at Meta's recommended resolutions. Reserve PNG for flat graphics, logos and hard-edged text where the crispness is worth the extra file size. If a PNG export pushes past 30 MB, switching it to a high-quality JPG usually fixes it without touching the pixel dimensions.

None of this touches ad policy, which is a separate gate. A perfectly sized asset can still be rejected on content grounds, so it is worth knowing Meta's content rules before you scale spend behind a creative.

Minimum resolution: what Meta actually requires

There is a persistent myth that Meta requires a 1080 px minimum on the short side. Meta's own per-placement spec pages tell a different story. The Feed page states a minimum width of 600 px, with a 600 x 750 px minimum at the 4:5 ratio. The Stories and Reels pages state a minimum width of 500 px. Those are the numbers Meta actually publishes in the 2026 ads guide.

The 1080 px figure appears in practitioner guidance, not on the loaded official spec pages, and it is a reasonable working floor rather than a hard requirement. Exporting near Meta's true minimums of 500 to 600 px will pass validation but can look soft on modern high-density phone screens, so most experienced advertisers export well above the floor. Meta's dedicated cross-placement minimum-size help page did not expose a single blanket number we could confirm, which is exactly why you should lean on the per-placement minimums above rather than a remembered rule of thumb.

The practical takeaway: do not design to the minimum. Design to Meta's recommended resolutions, 1440 x 1800 px for Feed and 1440 x 2560 px for full-screen, and you will never worry about a soft render or a rejected ratio.

Auto-crop versus per-placement assets

You do not have to make a separate file for every surface. Ads Manager will automatically crop or adjust a single uploaded asset to fit each placement's ratio, so one master can technically run everywhere. The catch is that auto-crop has no idea which part of your image is load-bearing. It can slice off a product edge, clip a line of text, or centre-crop away the exact detail you needed the reader to see.

You have two ways to keep control. The first is to design your single asset inside the safe zones so that whatever gets cropped, the message survives. The second is to upload customized per-placement assets in Ads Manager: a 4:5 for Feed, a 9:16 for Stories and Reels, a 1:1 for carousels, and a 1.91:1 for landscape. Per-placement assets give you exact control over what shows on each surface; safe-zone design gives you the widest reach for the least production effort.

When you run Advantage+ placements, which is the default for most modern campaigns, Meta takes your uploaded creative and adjusts it to fit whichever surface an impression lands on. In practice that can mean cropping a 4:5 into a square for a carousel slot, or repositioning a single asset toward the 9:16 shape for a full-screen placement. Meta does not publish the exact per-surface behaviour in a form we could quote verbatim, so treat auto-adjust as a convenience that fills gaps rather than a promise that your composition survives intact. The safe move is the same either way: if a surface genuinely matters to your plan, upload a purpose-built asset for it in the placement customisation panel, and let auto-adjust cover only the long tail of surfaces you did not design for. That keeps your most important placements pixel-controlled while still reaching everywhere Meta can deliver.

Which approach you choose interacts with how you set placements in the first place. If you let Meta optimise across all surfaces, safe-zone design matters more, because you cannot predict where each impression lands. The trade-offs are covered in automatic versus manual placements, and it is worth reading alongside this page, because the ratio decision and the placement decision are really one decision.

A build workflow: from two masters to a full set

Here is a workflow that keeps production light without leaving delivery on the table.

Start with the 4:5 Feed master at 1440 x 1800 px. This is your hero. Design the whole message to live comfortably inside it, with nothing critical jammed against the top or bottom edge.

Next, rebuild the same idea as a 9:16 master at 1440 x 2560 px for Stories and Reels. Do not just stretch the 4:5, because the extra vertical height changes the composition. Place your key message in the central band and respect the top 14% and bottom 35% safe zones. This is the asset most likely to be undermined by a lazy export, so give it real attention.

Then derive the extras only as needed. Crop or recompose a 1:1 square at 1440 x 1440 px when you run carousels or want Marketplace coverage. Build a 1.91:1 landscape at 1200 x 628 px only if you buy right-column or link placements. Most advertisers never need more than these four shapes.

One habit keeps this set from drifting out of date: version your files by ratio, not by campaign. Treat the 4:5, the 9:16, the 1:1 and the 1.91:1 as reusable base masters, so when Meta nudges a recommended resolution upward you re-export from the master rather than rebuilding the idea from scratch. Because all four shapes carry the same message and the same safe-zone discipline, absorbing a new recommended dimension becomes a quick re-render instead of a redesign.

Finally, decide whether to upload each master as a customized per-placement asset or to lean on auto-crop with safe-zone-safe design. A modern platform like AdPlay.ai keeps research, creative generation and launch in one place, which shortens the loop between spotting a winning shape and shipping the full set, but the ratios above hold regardless of the tools you use. If you are new to the whole sequence, the pillar guide on how to run a Facebook ad walks through where creative sizing fits in the larger launch.

Check Meta's specs, because they change

The single most useful habit is to treat Meta's ads guide as the source of truth and everything else, including this page, as a fast reference. Meta has revised its recommended pixel values upward over time. The short-side recommendation moved from 1080 px to 1440 px, and the Feed default shifted to 4:5. Those changes did not announce themselves loudly; they simply appeared on the spec pages.

The neutral and third-party sources are helpful for context and corroboration, but they lag, and they sometimes disagree, as the right-column ratio question shows. Before any launch where the creative budget is meaningful, open the relevant page in Meta's ads guide and confirm the current recommended ratio and resolution for the exact placement you are buying. It takes a minute and saves you from shipping a shape that was correct last year.

The ratios themselves, 1:1, 4:5, 9:16 and 1.91:1, have been stable for years and are unlikely to change. What drifts is the recommended pixel count and the default. Anchor your production to the two-master workflow and the safe zones, verify the numbers at launch, and your creative will render cleanly across every surface Meta serves it to. For a wider view of how these shapes map onto the different creative types, Meta ad formats explained closes the loop between size, shape and format.
