Instagram has a maximum aspect ratio of 4:5 on portrait posts (four pixels wide for every five pixels tall). Instagram’s restriction reduces the number of very tall images that take up a lot of vertical space in the feed. Although it’s nice that Instagram keeps users from publishing massive, obtrusive posts, the 4:5 limit makes it difficult to post a whole vertical picture or video that you shot on your phone.

If you want to fit your whole picture on Instagram but it is taller than the 4:5 aspect ratio, you need to modify your image before posting. Otherwise, Instagram will automatically crop your image to a maximum of 4:5. I recommend the Kapwing resizer as it allows you to add white space on either side to bring your image to the required aspect ratio. In this article, I’ll explain how to fit the whole picture on Instagram in three simple steps:

  1. Upload picture
  2. Resize to 4:5
  3. Download and Post to Instagram

Step 1: Upload Picture

Start by opening the Kapwing’s Resizer tool on your phone or computer. Upload your image file from camera roll or import it from a URL. Kapwing supports images, videos, and GIFs, so you can use it to resize for any kind of media.

Once your picture loads into the editor, you’ll be taken into the Kapwing Studio Editor where you'll see a preview of your image in the center of the screen.

Step 2: Resize to 4:5

In the Output Size section, select the 4:5 option. This allows your photo to take up maximum vertical space in the Instagram feed without getting sized down. There is a resizing option for Instagram, 1:1, but this shrinks your image to fit in the default square shape.

Once you have selected the size option, Kapwing adds white padding to either side of your image to make it fit the 4:5 aspect ratio. You can change this white background to any color you want so that it stands out in the Instagram feed.

Step 3: Download and Post

Click the red “Export Image” button at the top of the screen. After a few moments of processing, Kapwing makes your resized 4:5 picture or video available for download. Whether you're using a desktop computer, iPhone, Android, or tablet you'll be able to instantly download the image to your photo gallery once published.  Now it's ready for you to share anywhere!

Open the Instagram app and upload your picture. You’ll notice that Instagram crops the picture to square by default, but you can click the expand arrows or pinch the image in the lower left to fit the whole picture on Instagram. When you publish it, Instagram will resize to image width to fit the screen, the white image background will blend in with Instagram’s white background, and your whole picture will appear on Instagram with no cropping.

Note: You can also choose a black background, if you and your followers use Instagram in Dark Mode.

Conclusion

This tutorial shows you a workaround for posting full portrait pictures and videos on Instagram. You can use Kapwing’s Resizer to post multiple images with different sizes on Instagram, add a thin white border around your media, and publish TikTok and Snap videos. I hope that it helps speed up your social media workflow and enables you to post your beautiful and fun candid moments to Instagram.
