[Publish] Image and video aspect ratios for Instagram posts
IN THIS ARTICLE
Due to the limitations with Instagram's new API, we're only able to publish posts automatically if the image or video aspect ratio is within Instagram's accepted range, as detailed below.
|Media type||Aspect ratio range||Aspect ratio range as numerical values|
|Image||Between 4:5 and 1.91:1||Between 0.8 and 1.91|
|Video|| Between 4:5 and 16:9
||Between 0.8 and 1.78|
An image or video’s aspect ratio describes the ratio between its width and its height. Aspect ratios are often represented as two numbers separated by a colon, e.g. 4:5. This can be a convenient way of displaying an aspect ratio and can be converted into a numerical value by dividing the first by the second. So, for example, an aspect ratio written as 4:5 has a value of 4/5 = 0.8.
Provided your image or video is within the accepted aspect ratio range, your post can be published automatically. If the aspect ratio of your image or video falls outside of the range, your post will be scheduled as a reminder instead. If you like, you can adjust the aspect ratio and then re-upload your image or video.
How are aspect ratios calculated?
To calculate the aspect ratio of an image or video, you can take the resolution and divide the width by the height. Here are some examples:
- 1200 x 1200 pixels: Aspect ratio of 1200/1200 = 1
- 1200 x 1500 pixels: Aspect ratio of 1200/1500 = 0.8
- 1200 x 629 pixels: Aspect ratio of 1200/629 = 1.907
Remember to watch out for rounding the results of your calculation digits. For example, 1200 x 628 pixels would correspond to an aspect ratio of 1.910828, therefore falling just outside of the acceptable range for an image. Similarly 799 x 1000 pixels would correspond to an aspect ratio of 0.799, again falling just outside of the acceptable range.
What sizes do my images and videos need to be?
Your image or video doesn’t need to be a specific pixel size, as long as the aspect ratio is within the acceptable range. Here are some example sizes that would work nicely:
- Any size square image or video (same width and height), e.g. 600 x 600 pixels, 800 x 800 pixels, 1200 x 1200 pixels
For portrait images and videos, the aspect ratio must be 0.8 or less
- 600 x 900 pixels (aspect ratio 0.67)
- 800 x 1000 pixels (aspect ratio 0.8)
- 1200 x 1500 pixels (aspect ratio 0.8)
For landscape images, the aspect ratio must be 1.91 or less, and for landscape videos, the aspect ratio must be 1.78 or less
- 800 x 600 pixels (aspect ratio 1.33)
- 1200 x 800 pixels (aspect ratio 1.5)
- 1500 x 1200 pixels (aspect ratio 1.25)
- Your images and videos do not need to be any of the one sizes mentioned above, these are just examples. As long as they are within the accepted aspect ratio ranges, they will be published automatically.
- Instagram accepts a minimum resolution of 150 x 150 pixels and a maximum of 1920 x 1080 pixels for images. Lower resolutions will be scaled up to the minimum and higher resolutions will be scaled down to the maximum.
