Ad Creative Ratios: The Right Size for Every Placement

Use 9:16 for Reels, Stories, TikTok and Shorts, and 4:5 or 1:1 for feeds. Keep 16:9 for YouTube and LinkedIn placements that still play horizontally. Most other choices are variations on those four ratios. If you shoot once and plan the framing before you hit record, one piece of footage can serve nearly every placement you pay for.

This guide covers what a ratio actually is, which ones each platform wants, the video ad sizes behind them, where to keep text, and how to export so nothing gets cropped.

TL;DR

• 9:16 (1080x1920) is the default for Reels, Stories, TikTok and YouTube Shorts ads.
• 4:5 (1080x1350) is the strongest feed shape on Facebook and Instagram when your video is already vertical. 1:1 (1080x1080) is the safe fallback.
• 16:9 (1920x1080) still belongs on YouTube and LinkedIn, but rarely on mobile social feeds.
• Frame the important content in the center of the asset, because placements crop and interface buttons cover the edges.
• Check every placement preview before you publish.

What an ad creative ratio actually is

An aspect ratio is the relationship between width and height. A 1:1 ratio means width and height are equal, so a square. A 9:16 ratio is nine units wide for every sixteen tall: a phone held upright.

Pixel dimensions are a separate thing. The same ratio can come in many sizes. 1080x1920 and 540x960 are both 9:16, one simply carries more detail and a bigger file.

That is why platforms care about ratio first. The industry has been moving the same way: the IAB replaced fixed pixel sizes with flexible ad units built on aspect ratios, so an ad can scale across screens and keep its shape. In practice, pick the ratio to win placement eligibility, then pick a resolution that stays sharp without breaking file size limits.

The four ratios you will use

Vertical 9:16

Vertical fills the whole phone screen, which leaves no competing content around your ad. It is the native shape for short-form video, so it feels like content rather than an interruption. Google recommends vertical 9:16 for YouTube Shorts, and the same file will run on Reels, Stories and TikTok.

Portrait 4:5

In a feed, 4:5 takes up more vertical space than a square, so your ad pushes neighboring posts further off the screen. It is the best feed choice when your footage is already vertical, such as a portrait-style product photo or a clip shot upright. It is also the one ratio that is not full screen, so you can still read it as a post rather than a takeover.

Square 1:1

Square is the compromise. It works almost everywhere and looks acceptable on desktop and mobile alike, which makes it useful when you need one safe asset. It rarely wins on its own, because it fills less of the screen than 4:5 or 9:16.

Landscape 16:9

Horizontal video still earns its place where people watch on a laptop, TV or a phone turned sideways. YouTube is the clearest case. On mobile social feeds, though, a landscape clip uses a small strip of the screen, so test it before committing budget.

Video ad sizes by platform

Facebook and Instagram (Meta)

The common numbers for Meta are 1080x1920 (9:16) for Stories and Reels, and 1080x1080 (1:1) or 1080x1350 (4:5) for feed.

There is a higher-resolution recommendation too. For Stories and Reels ads, Sprout Social lists 9:16 at 1440x2560, and Facebook feed video at 4:5 and 1440x1800. If you shoot in 4K, export at those sizes. If you export at 1080 pixels wide, you still clear the minimums, so there is no need to re-edit finished work just to hit the bigger figure.

YouTube

Google’s ad help page states that YouTube recommends 1920x1080 (16:9) for horizontal and 1080x1920 (9:16) for vertical video. It adjusts the video to the viewer’s device without stretching or cutting content. For Video and App campaigns, Google recommends horizontal 16:9, vertical 9:16 and square 1:1 assets, so supplying all three gives the system room to match each screen.

TikTok

TikTok in-feed ads are built for 9:16. The published minimum resolution is 540x960, though in practice you should upload 1080x1920 so the video does not look soft on newer phones. Confirm the current figures in TikTok’s own ads help center before you build a template, because platforms revise specs.

LinkedIn

LinkedIn video ads accept several shapes, including 16:9, 1:1, 4:5 and 9:16. If your audience sits mostly on desktop, 16:9 or 1:1 is a sensible start. If you are targeting people on phones, test 4:5 and 9:16 against it.

Quick reference

Safe zones: where text and logos survive

Every vertical placement lays buttons, captions, profile names and reaction icons on top of your video. If your headline sits in the wrong spot, the platform covers it.

For Meta vertical ads, one guide advises keeping text and logos out of the top 14%, the bottom 35% and 6% on each side. On a 1080x1920 canvas, that leaves roughly the middle half of the frame for your most important words. Treat these numbers as a working rule and confirm with Meta’s own placement previews, because overlays change.

A few habits make this easy:

1. Put a guide layer in your editing template with the top, bottom and side margins marked.
2. Place your hook text in the upper-middle, below the top margin.
3. Put your call to action well above the bottom band, never on the very lowest strip.
4. Keep faces centered. A face cut off at the chin looks like a mistake.

It also helps to think about the story the frame tells. If you want ideas on composing for vertical, visual storytelling tips can help you decide what earns the center of the frame.

One creative for every placement, or separate versions?

Short answer: shoot once, but cut more than one version.

Meta’s Advantage+ placements can auto-crop your asset to fit where it lands. That is why putting essential elements in the center of the asset is critical. If your key action happens at the edge of a 16:9 frame, the vertical crop will lose it.

A workable plan:

• Shoot wide, frame tight. Record in a way that keeps the subject in the middle third, so 9:16, 4:5 and 1:1 can all be pulled from the same take.
• Make two or three cuts. A 9:16 for Reels and Stories, a 4:5 for feed, and a 1:1 as the catch-all.
• Rewrite on-screen text per cut. A line that sat comfortably in 9:16 may collide with the edge of a square.
• Leave the placements open at first. Let delivery show you where the ad works, then build custom versions for the placements that spend.

The IAB makes the broader point that media consumption across mobile, desktop, smart TVs and AR/VR calls for responsive, ratio-driven design rather than fixed pixel sizes. A creative built with flexible margins ages better than one built for one exact canvas.

Which ratio should win your first test

Don’t guess from a blog, including this one. Run a small structured test.

1. Take one winning hook and cut it in 9:16, 4:5 and 1:1.
2. Run them in the same ad set with the same audience and budget.
3. Judge them on cost per result and, for video, how many people watch past the first few seconds.
4. Keep the winner, then iterate on the hook, not the ratio.

Expect the answer to vary by audience. A fitness coach selling to people who scroll Reels all day will often see 9:16 win. A B2B offer on LinkedIn may do better in square. The point of testing is that your numbers replace the average.

Perspective: what we see when creators launch

We work with creators in the Balkans and the diaspora who sell their first paid program, and ratio mistakes are among the most common reasons a good offer looks weak in an ad. The footage was shot for a YouTube-style horizontal frame, then squeezed into Reels. The coach’s face is small, the text is under the caption bar, and the first second shows nothing.

Our rule is to plan the ad before the shoot. We decide which placements will carry the budget, shoot vertical with the subject centered, and keep a clean margin for text. Ad creative is only one link in a launch, though. The ad earns the click, and the page behind it has to close the sale on the same phone. If your creative is vertical and your page is not, you lose people at the handoff, which is why we also care about mobile-first sales pages.

Our experience is in Southeast European audiences, where engagement is high and creators often have never run a paid ad. For them, getting the format right on day one is a cheap way to avoid wasting early budget.

Export and preview checklist

The last mile is where most format errors appear. Before you upload:

• Decide the placement before you edit. It is far easier to frame for 9:16 than to rescue a landscape clip later.
• Use MP4 with H.264 and a constant frame rate that matches how you recorded, as Sprout Social advises.
• Export at the recommended dimensions in high quality, then check the previews in the ad platform before publishing so you catch cropping.
• Balance quality and weight. Higher resolution improves sharpness but raises file size and load times, and heavy compression can blur small type. Small text is the first thing to suffer.
• Watch it on a real phone. Send the file to your own device and view it with the screen brightness and caption bar your audience will see.

One more point from Meta-focused guides: 1080-pixel-wide files still clear every minimum, even where the recommendation is 1440 wide. Do not delay a launch to re-render.

Common mistakes to avoid

• Uploading a landscape video to a vertical placement. The platform adds bars or crops, and either looks cheap.
• Text in the bottom band. The caption and call-to-action button will sit on it.
• Square everything. It is safe, but you give up the screen space that vertical formats claim.
• Ignoring sound-off viewing. Use captions inside the safe zone.
• Changing the ratio and the hook in one test. You will not know which one caused the result.

FAQ

What is the best ratio for video ads?

For most mobile placements it is 9:16, because it fills the screen on Reels, Stories, TikTok and Shorts. For Facebook and Instagram feeds, 4:5 is usually stronger than 1:1 if your video is vertical. Test both against your own audience.

Can I use the same video on every platform?

Yes, if you frame it with the subject centered and keep text inside the safe zone. A single 9:16 master can run on Reels, Stories, TikTok and Shorts. For feeds and YouTube standard placements, cut a 4:5 or 16:9 version for better fit.

What size should a vertical video ad be?

Export at 1080x1920 pixels, which is 9:16. Meta recommends going higher, up to 1440x2560, for Stories and Reels, but 1080 wide still meets the minimums. The ratio matters more than the exact pixel count.

Do aspect ratio and resolution mean the same thing?

No. Aspect ratio is the shape, width compared to height. Resolution is the number of pixels inside that shape. Two files can share one ratio and differ in sharpness.

Where should I put text in a vertical ad?

Keep it in the central area, away from the top and bottom bands and the side edges, where interface elements sit. A common guide is to avoid roughly the top 14% and bottom 35% on Meta. Always check the placement preview before you publish.
