Why is it important to post in the right size on Instagram?

When viewing posts in theInstagram feed , stories, or reels, people have the option to quickly scroll down. Everyone who owns a cell phone and regularly looks at social media posts knows how this works. But what does this have to do with the right Instagram post size? Well, it's simple! It's increasingly difficult to hold people's attention; it's very easy for users to move on to the next post, story, or reel. And if your post is the wrong size, the viewing of the entire image content may be compromised. A good post has the power to generate more engagement, strengthen the brand image, and create a greater impact on the audience. On the other hand, a poorly planned post, with a size not accepted by Instagram, will appear cropped to users, significantly reducing the chances of generating good engagement and harming the user experience when viewing this content.

What is the recommended Instagram post size in 2025?

For 2025, the Instagram feed underwent an update . Previously, the standard Instagram post size was square, with a 1080 x 1080 px ratio. However, if you use Instagram regularly, you may have noticed a large volume of posts in a new rectangular format. The new format for Instagram images is 1080 x 1350 px . According to Adam Mosseri, CEO of the company, the new size aims to improve the viewing experience of images published on Instagram. This is because, with the adopted rectangular ratio, images fill the screen of users' cell phones, which can increase interactions with the post. After all, the experience becomes much more immersive, a differentiating factor with great potential to be leveraged in strategies to gain thousands of likes on Instagram .

Meta had already been evaluating changes for some time.

The update that changed the format of images in the Instagram feed had been under evaluation by Meta for some time. According to CEO Adam Mosseri, the verticalization of the feed had been under study. The company concluded that the vertical format is better suited to content production, whether photo or video, in current times. This makes sense when we consider that the cell phone is the main and most accessible means of recording images and videos today, and that its format is rectangular, recording in that same proportion. Before, it was necessary to crop images taken with the cell phone to fit the social network's format; now this is no longer necessary. Despite this, there were those who did not like the change and continue to prefer the old format.

So, I can't use square images anymore?

Instagram users who prefer the old square post size format can still use this option. When configuring the post, there's an option to add borders to the image, preventing it from being cropped during publication. The tool that allows this adjustment to square images came with the same update that changed the size and aspect ratio of images published in the feed.

Instagram post size landscape

It's also possible to post in landscape size on your Instagram feed. In this case, the images are displayed in Instagram post size 1080 x 566 px . That is, the image width is greater than its height, resulting in a better viewing experience for landscape images. This way, the user only needs to open the image in full screen and turn their phone horizontally (with the auto-rotate option enabled). Then, the image will adjust to the device's screen, filling the smartphone screen for an immersive and complete viewing experience.

Instagram Story post size

Stories are posts that remain visible for only 23 hours. After that, they disappear and can only be retrieved by the profile owner through the archive option, accessible in Instagram settings. However, the account owner can also select their favorite stories to appear as highlights below their profile. For Instagram Stories, the format remains at a 9:16 aspect ratio, or 1080 x 1920 px. This format fills smartphone screens and provides an equally immersive viewing experience. Want to take a quick peek at someone's story? Check out how to view stories anonymously on Instagram .

Reels are short videos that users can view in infinite scrolling, similar to TikTok and Kwai videos. It's important to publish content of the appropriate size if you use reels in your strategies to increase engagement on Instagram , as users tend to interact a lot with videos, and short videos are one of the most successful publication formats on Instagram. Therefore, know that the Instagram reels post size is the same as the stories size (1080 x 1920). After all, the goal is precisely for reels videos to fill smartphone screens, with the 9:16 aspect ratio being the best choice for this.

What is the difference between photo size and aspect ratio on Instagram?

The difference between size and aspect ratio is that the former refers to the maximum width and height an image can have on the social network. Aspect ratio, on the other hand, indicates the format. For example, for square images, the maximum size is 1080 x 1080 px, and the aspect ratio is 1:1, indicating that both sides of the image are the same size. In Instagram's format, the maximum size is 1080 x 1350 px, and the aspect ratio is 4:5, indicating that the image width is slightly smaller than its height. Keep this in mind when considering the Instagram post size for your publication. Remember that the dimensions for posting to the Instagram feed on mobile are the same as for posting on Instagram Web .

Can I post images to my Instagram feed that are the same size as Instagram Stories?

Yes, you can use the Instagram Stories post size for posts on your feed. In fact, this is possible with any image format. However, your image will be cropped, preventing users from fully viewing your content when the post appears, even in full screen. The same will happen if you post to your Stories at your feed size.
