Video Aspect Ratios in 2026: 16:9, 9:16, 4:5 and 1:1
Use 16:9 for YouTube and websites, 9:16 for Shorts, Reels, Stories and TikTok, and 4:5 for Facebook and Instagram feed placements. 1:1 still works almost everywhere, but it rarely fills the screen, so it is a compromise rather than a first choice.
The hard part is not knowing the numbers. It is planning one video so that each version looks like it was made for its platform instead of cropped to fit it. That planning is what this post is about.
What aspect ratio should a YouTube video be?
16:9. YouTube's own help page says the standard aspect ratio for YouTube on a computer is 16:9, and that the player adjusts itself to other shapes.
Two details matter in practice. First, YouTube asks creators not to add their own black bars or padding, because the player already handles vertical and square videos: on a computer, a 9:16 video gets padding added around it automatically. Burned-in bars just make the picture smaller on every device. Second, a horizontal video is still the right master for a landing page, a pitch deck or a TV screen, which is why most projects start in 16:9 even when most views will come from phones.
What aspect ratio should Shorts, Reels and TikTok videos be?
9:16, full vertical. All three are built around a phone held upright, and 9:16 is the only shape that fills that screen edge to edge.
- YouTube Shorts: vertical or square, and YouTube's help center describes Shorts as short-form videos of up to 3 minutes.
- TikTok In-Feed ads: TikTok's ad specs list vertical 9:16 as the recommended ratio, at 540x960 pixels or more, and also accept 16:9 and 1:1. Non-Spark in-feed ads can run up to 10 minutes.
- Instagram and Facebook Reels: 9:16, with room left for the interface (more on that below).
A 16:9 video posted into these feeds shows up as a thin strip in the middle of a tall screen. It is not broken, but it tells the viewer immediately that it was made for somewhere else.
Why 4:5 for Facebook and Instagram feeds?
Because it is the tallest shape the feed shows without going full screen. Meta's ads guide lists 4:5 as the recommended ratio for feed video ads.
A 4:5 frame takes more vertical space in the scroll than a square, and far more than 16:9, while still sitting inside the feed rather than taking it over. If a campaign runs in both feed and Reels, the practical setup is two exports: 4:5 for feed, 9:16 for Reels and Stories.
What is the safe zone, and why does it change the design?
The safe zone is the part of a vertical frame that the app's interface will not cover. Meta's Reels ad specs suggest leaving roughly 14% at the top, 35% at the bottom and 6% on each side free of text, logos and key elements, so the profile icon and the call-to-action button do not hide them.
Thirty-five percent at the bottom is a lot. It means the natural place for a caption on a horizontal video, the lower third, is exactly where a vertical version will be covered. Titles, product names and the one line of text that carries the message have to live in the middle band of a vertical frame. This is why a vertical version cannot just be a center crop of the horizontal master with the same text burned in.
Is 1:1 still worth making?
Sometimes. Square video is accepted almost everywhere, including TikTok ads and Shorts, so it is a safe single export when budget or time only allows one file. But it is the right shape almost nowhere: smaller than 4:5 in feeds, and far from full screen in vertical apps. Treat 1:1 as a fallback, not a plan.
How do you plan one video for every ratio?
Decide the shapes before anything is designed, not after the edit. A few rules make the difference:
- Pick the master by where the money is. If the video mainly runs as a paid social ad, the vertical version deserves to be designed first, not derived last.
- Keep the subject in the center column. A subject framed in the middle third of a 16:9 frame survives a 9:16 crop. One framed on the left edge disappears.
- Put text on its own layer. Text should be placed separately for each ratio so it stays inside each platform's safe zone, instead of being burned into the picture once.
- Plan the hook per format. The first seconds in a vertical feed need the subject large and centered immediately. We wrote about why in the first three seconds.
- Design for sound off. Many feed viewers never turn sound on, so the vertical cut should make sense silently.
How we handle it at FromDemo
Every package starts with a script and storyboard that are approved before production, which is the point where framing for each shape gets decided. Our Standard package includes 3 vertical social cuts alongside the main video, and the social cutdowns page shows a real vertical cut from a finished project. For a format that lives mostly on phones, like a launch teaser, the video can simply be made vertical from the start: our ORRA studio demo was produced natively in 9:16 rather than cropped.
If you want to see how your brand would look in motion before deciding on formats or budgets, the free 15-second sample is the quickest way to find out, and the packages list exactly what each one includes.
Frequently asked questions
What is the best aspect ratio for Instagram Reels?
9:16, full vertical. Keep text and logos out of the top 14%, the bottom 35% and about 6% on each side, which is the area Meta suggests leaving clear so the interface does not cover it.
Can I post a 16:9 video to TikTok or Shorts?
You can. TikTok ads accept 16:9, and YouTube adds padding around videos that do not fill the player. But a horizontal video shows as a small strip on a vertical screen, so a dedicated 9:16 version almost always looks and performs more like native content.
Should I add black bars to make a video fit?
No. YouTube specifically asks creators not to add their own padding or black bars, because its player adjusts to different shapes automatically. Burned-in bars make the picture smaller on every screen.
Is 4:5 or 1:1 better for Facebook and Instagram feed ads?
4:5. Meta's ads guide lists 4:5 as the recommended ratio for feed video, and it takes more space in the scroll than a square. Keep 1:1 as a fallback when only one file can be made.
