If you're exporting a vertical ad right now, here's the short version: build and export at 1080×1920 pixels, in a 9:16 aspect ratio, at 30 frames per second. That single resolution covers TikTok, Instagram Reels, Facebook Reels, YouTube Shorts and Meta's placement network without any extra work. The rest of this guide explains why that number is the sensible default, when you might go higher, and how resolution interacts with aspect ratio, safe zones and bitrate so your ad actually looks sharp instead of just technically passing a spec sheet.
The recommended resolution for vertical video ads, in one sentence
For TikTok, Instagram, Facebook and YouTube vertical ad placements, the recommended resolution for vertical video ads is 1080 pixels wide by 1920 pixels tall, delivered as a 9:16 aspect ratio file. This is often described as "Full HD vertical" and it's the resolution every major ad platform's upload tool is built around. Export at this size, keep your frame rate at a standard 24, 25 or 30 fps, and you've cleared the single biggest technical hurdle in making a vertical ad.
You don't need 4K. You don't need a custom size per platform. 1080×1920 is the one resolution that works as a universal export, which matters a lot if you're producing ads for multiple networks from the same source file — see our guide on creating vertical video ads for multiple platforms if that's your situation.
Why 1080×1920 became the standard
Three things lined up to make 1080×1920 the default rather than an arbitrary choice:
- Most phone screens display content in roughly that pixel range or scale cleanly from it, so footage looks crisp without the file being unnecessarily large.
- Every major vertical ad placement — TikTok in-feed, Reels, Shorts, Stories — is designed around a 9:16 frame, and 1080×1920 is the resolution that maps to that ratio at a widely supported pixel count.
- It balances visual sharpness against file size and upload/processing time, which matters when ad accounts are reviewing and re-encoding thousands of uploads.
In practice, this means 1080×1920 isn't a minimum you're scraping by with — it's the sweet spot. Anything meaningfully below it (say, 720×1280) will look noticeably softer, especially on text and product detail. For a deeper look at the lower bound and what happens if you go under it, see our minimum resolution for vertical video ads guide.
Do you ever need higher than 1080×1920?
Occasionally. If you're shooting footage that you plan to crop in tightly during editing — zooming into a product detail shot, for example — recording at a higher source resolution (like 4K vertical) gives you room to crop without losing sharpness. But the final exported ad file you upload to the ad platform should still come down to 1080×1920. Submitting a 4K vertical file doesn't make the ad look sharper in-feed; it mostly just adds file size and upload time. Treat higher resolution as a production buffer, not a delivery spec.
Resolution, aspect ratio and safe zone are three different things
A lot of confusion around vertical ad specs comes from treating resolution as the whole story. It isn't. Three separate settings need to be right together:
- Resolution — the pixel dimensions of the file (1080×1920). This determines sharpness and detail.
- Aspect ratio — the shape of the frame (9:16 for full vertical). This determines how much of the screen your ad fills and whether it gets cropped or letterboxed.
- Safe zone — the area of the frame that stays visible once platform UI elements (captions, like/share buttons, profile info) are overlaid on top. This determines where you can safely put text and logos.
You can hit the correct resolution and still have an ad that fails, because your call-to-action text sits where the comment box or follow button will cover it. Resolution gets your pixels right; safe zone gets your layout right. If you haven't mapped out where platform UI typically sits, our safe zone guidelines for vertical video ads article walks through it placement by placement.
Resolution by platform: what actually changes
The good news is that for vertical ad placements specifically, the differences between platforms are small. The table below shows what to use as your default per platform.
| Platform / placement | Recommended resolution | Aspect ratio | Notes |
|---|---|---|---|
| TikTok in-feed ads | 1080×1920 | 9:16 | Full-screen vertical is the native format; avoid letterboxing. |
| Instagram Reels ads | 1080×1920 | 9:16 | Same file works for Stories placements too. |
| Facebook Reels / Stories ads | 1080×1920 | 9:16 | Meta's ad tools also accept 4:5 and 1:1 as secondary crops. |
| YouTube Shorts ads | 1080×1920 | 9:16 | Keep key content centered; Shorts UI sits along both edges. |
| Snapchat vertical ads | 1080×1920 | 9:16 | Check platform-specific length and safe zone rules separately. |
If TikTok is your primary channel, it's worth reading the fuller video resolution requirements for TikTok ads guide, since TikTok's upload tool has a few quirks around file format and compression that go beyond just pixel dimensions.
Resolution alone won't make your ad look sharp
This is the part creators miss most often: a file can be exactly 1080×1920 and still look blurry, blocky or soft in-feed. That's almost never a resolution problem — it's a bitrate problem. Resolution tells you how many pixels exist; bitrate tells you how much data is used to describe those pixels frame to frame. Export a 1080×1920 video at too low a bitrate and the platform's own re-compression will make it look worse than a lower-resolution file exported cleanly.
If your ads come back from the platform looking muddier than what you uploaded, check your bitrate before you assume resolution is the issue. Our recommended bitrate for vertical video ads guide covers starting points to test, and the companion piece on recommended bitrate for social media video ads covers the broader picture if you're exporting for feed posts as well as ads.
Common mistakes when getting resolution right
- Stretching a horizontal video to fill a vertical frame. This distorts faces, text and product shapes. Reframe the shot or recreate the ad for 9:16 instead of stretching 16:9 footage.
- Center-cropping a horizontal video without checking what's lost. A straight crop can cut off a product, a face, or on-screen text that was positioned for a wide frame.
- Exporting at an odd resolution close to but not exactly 1080×1920. Some editing tools default to slightly different pixel counts; always double-check the export settings before upload.
- Re-exporting an already-compressed file multiple times. Every export pass can degrade quality further, even if the resolution stays the same. Work from your original source file whenever you need to make a change.
- Assuming higher resolution fixes a shaky or poorly lit shot. Resolution describes pixel count, not image quality. A crisp 1080×1920 export of a dim, shaky clip will still look dim and shaky — just with more pixels doing it.
Getting the resolution right without owning a video team
If you're a small e-commerce brand or a one-person marketing team, the honest challenge usually isn't knowing the number 1080×1920 — it's producing a vertical ad from scratch, hitting that resolution, keeping text inside the safe zone, and doing it fast enough to test more than one hook a week.
This is the gap FrameNotion is built to close. You paste a product or website link, FrameNotion AI writes a 30-second vertical ad for that product — hook, problem, benefit, proof, offer, call to action — and renders it as a 1080×1920, 9:16, 30 fps MP4, which is exactly the resolution and ratio covered in this guide. It checks its own rendered frames before handing you the file, and a finished ad takes about 10 to 20 minutes. If you'd rather start from a poster or flyer instead of a link, FrameNotion can also turn that into a motion poster — animating the title, artwork and badges to music and ending on the original design, still exported at the same vertical specs.
Every ad also comes with a matching 4:5, 1:1 and 16:9 version, so the same resolution logic covered above is already handled if you also need a square or landscape cut for other placements. You can see finished examples on the examples page, read how the process works on features, or check plans on pricing — the first ad is free, no card required.
A quick resolution checklist before you upload
- Export at 1080×1920 pixels, 9:16 aspect ratio.
- Confirm frame rate is a standard value (24, 25 or 30 fps) and consistent throughout the file.
- Check bitrate is high enough that the exported file doesn't already look soft before you even upload it.
- Preview with platform UI overlays on to confirm text and logos sit inside the safe zone.
- Avoid uploading a stretched or heavily cropped horizontal video — recreate it natively for vertical instead.
Get through that checklist and you've covered the part of ad quality that's purely technical — leaving you free to focus on the hook, the offer and the call to action, which is where the actual performance differences usually show up.
Frequently asked questions
Is 1080×1920 the same as 9:16?+
Yes, for practical purposes. 9:16 is the aspect ratio (the shape of the frame), and 1080×1920 is the specific pixel resolution that produces that ratio. You'll sometimes see other pixel counts at the same 9:16 ratio, like 720×1280, but 1080×1920 is the recommended default because it looks sharper without being unnecessarily large.
Can I upload a square or horizontal video and have the platform make it vertical?+
Most platforms will technically accept it, often by adding blank bars (letterboxing) or auto-cropping the sides. Both usually hurt performance because the ad doesn't fill the screen or loses important content. It's better to export a native 1080×1920 vertical file from the start.
Does higher resolution mean a bigger file size?+
Yes, generally. Going above 1080×1920 increases file size for upload and storage without a real quality improvement in most ad placements, since the platform will typically compress it down anyway. Keep source footage high-res if you plan to crop, but export the final ad at 1080×1920.
Why does my 1080×1920 video still look blurry after uploading?+
This is usually a bitrate or compression issue, not a resolution issue. The platform re-encodes uploaded video, and if your original export had a low bitrate, that soft or blocky look gets amplified. Check your export's bitrate settings before assuming the resolution is wrong.
Do I need a different resolution for YouTube Shorts versus TikTok?+
No. Both use 1080×1920 at a 9:16 aspect ratio as the recommended vertical ad resolution. The differences between platforms are more about safe zones, UI overlays and length limits than resolution itself.
