What should my aspect ratio settings be for an Instagram ad? I am trying to design a video for my ad in Instagram, but when I upload the video, it says:


Story media aspect ratio has to be smaller than or equal to 9:16
Aspect ratios of videos need to be 1:1.


What should be the settings?
It means that the ratio between the width and the height of the content (in pixels) should be the specified one.

Specifically, for a video you need to have an aspect ratio (technically, a DAR - display aspect ratio) of exactly 1:1, so the width of the video should be the same as the height of the video. In other words, the video should be square. As an example, 1000 pixels x 1000 pixels is fine, because (1000 / 1000) == 1.0, while 1280 x 720 is not, because the division is not 1.

For what they call "story media", the aspect ratio should not exceed 9:16 (which is 16:9 in vertical). In numbers, that's 0,5625. So in this case the "media" you're uploading shouldn't be exceeding that 0,5625 value, when calculating the ratio between the width and the height of the content.
