Instagram aspect ratio and image size for 2026 now center on a taller 4:5 format, which means 1080 x 1350 pixels is the safest default if you want your posts to display correctly on the feed and profile grid. Square posts and landscape images still work, but they often get cropped in the grid view, which can affect how your content looks to new Instagram users.
Instagram has been around since 2010, but this shift away from the classic square format is one of the most visible changes inside the app. The platform is clearly prioritizing portrait orientation images, vertical video posts, and content that fits how people naturally scroll on mobile screens.
In this guide, we’ll break down the recommended Instagram sizes for feed posts, Stories, Reels, and video posts, along with how different aspect ratio values affect display, resolution, and visibility across the platform.

Short summary
- The Instagram aspect ratio has shifted to 4:5 for feed posts, which means 1080 x 1350 px is now the safest size to avoid cropped images on your profile grid.
- Feed and profile display are different, your images and videos may look fine in the feed but get cropped in the grid preview, especially square and landscape posts.
- Aspect ratio defines how your content fits on screen, with formats like 1:1 (square), 4:5 (portrait), and 16:9 (landscape) affecting visibility and layout.
- Use consistent dimensions across images and videos, especially in carousels, to prevent resizing issues and maintain a clean grid.
- Design with safe zones in mind, keeping text and key elements centered so they remain visible across all placements in the Instagram app in a supported ratio.
- Match the format to your goal, use portrait photos and videos for most feed posts, square for symmetry, landscape for width, and Stories or Reels (9:16) for full-screen impact.
How will the new 4:5 Instagram grid aspect ratio affect profiles?
The switch from the 1:1 square format to a 4:5 ratio changes how your Instagram grid looks. Your images will be cropped on the sides and appear as rectangles instead of squares in the new Instagram grid. Your square videos may show black borders at the top and bottom to fit the new, more vertical format.
It’s important to understand that there’s now a difference between how posts appear in the feed and how they display on your profile grid. In-feed, your images and videos are shown in their original aspect ratio. But on your profile page, the grid preview applies a 4:5 crop, which can cut off parts of your visual to create vertical images.
If you’ve spent time designing square images or keeping important elements near the edges, this change can affect how your content is seen. Text, logos, or key details placed too close to the sides may no longer be fully visible in the grid.
For example, a quote graphic that looks balanced as a square post might lose part of the text when it’s cropped into the new grid view. The same applies to branded layouts or puzzle-style grids, where alignment across multiple posts depends on consistent Instagram post dimensions.
Because of this, safe zones matter more than before. Keeping your main content centered helps ensure it stays visible across both feed and grid displays, regardless of the format you upload.
Once you understand how the grid crops content, the next step is choosing the right image dimensions for each format.
Instagram aspect ratio and image sizes explained
If you want your content to display correctly on Instagram, you need to understand how the correct aspect ratio and image and video sizes work together. The platform now favors a 4:5 aspect ratio for feed posts, which means 1080 x 1350 px is the safest size for most images and videos.
If you only remember one size, make it 1080 x 1350 px. It ensures your posts look right in both the feed and the profile grid without getting cropped. That’s why the right image size and aspect ratio are so important and why so many social media creators use an image manipulation service to edit their visual content and resize images.
What is an aspect ratio?
An aspect ratio is the proportional relationship between the width and height of an image or video. It’s expressed as two numbers separated by a colon, like 1:1, 4:5, or 16:9.
- The first number represents the width
- The second number represents the height
For example:
- 1:1 creates a perfect square
- 4:5 creates a vertical (portrait) image
- 16:9 creates a wide (landscape) format
Aspect ratio determines how your content fits on the screen, how it’s displayed in the Instagram app, and whether parts of your image or video get cropped.
Instagram feed images
Until recently, Instagram was known for its iconic square grid, which was made of square photos with a 1:1 aspect ratio.
Going down memory lane, there was a time when every image had to be cropped into a square, often cutting off important details and lowering image quality. Now, Instagram displays multiple formats, but the grid preview still favors vertical content and shows the same size across all posts.
That means square photos and landscape images may display correctly in the feed but appear cropped on your profile, so they’re not the ideal Instagram image size.
Recommended Instagram image sizes:
- Portrait images: 1080 x 1350 px (4:5)
- Vertical portrait: 1080 x 1440 px (3:4)
- Landscape images: 1080 x 566 px (1.91:1)
- Square images: 1080 x 1080 px (1:1)
Instagram feed videos
The same aspect ratio rules apply to video posts. Using the same Instagram dimensions for images and videos (and their custom cover photo) helps maintain consistency across your grid.
You can upload portrait, square, or landscape videos from your camera roll, but not all formats perform equally well visually, so you need to be careful to the minimum and maximum file size.
Recommended Instagram video sizes:
- Portrait videos: 1080 x 1350 px (4:5)
Minimum resolution: 600 x 750 px
Maximum resolution: 1080 x 1350 px - Square videos: 1080 x 1080 px (1:1)
Minimum resolution: 600 x 600 px
Maximum resolution: 1080 x 1080 px - Landscape videos: 1080 x 608 px (16:9)
Minimum resolution: 600 x 315 px
Maximum resolution: 1080 x 608 px
Landscape videos can still use a 16:9 ratio, but they take up less vertical space on screen, which can reduce visibility when users scroll.
Instagram stories
Instagram Stories are designed for a full-screen vertical format.
Recommended Instagram Stories size:
- Stories (images and videos): 1080 x 1920 px (9:16)
If you upload images that are smaller or use the wrong ratio when you create Instagram Stories, your content may appear with black borders or reduced visual quality, so you have to pay attention to the correct Instagram Story size.
Instagram reels
Reels use the same vertical aspect ratio as Stories but appear across multiple placements, including the feed and Reels tab, usually with a custom cover image.
Recommended Instagram Reels size:
- Reels (videos): 1080 x 1920 px (9:16)
Reels are also becoming a bigger priority for brands. Posting volume has shifted toward this format, with brands increasing how often they publish Reels by about 33% year over year. That makes getting the right size and exact dimensions even more important if you want your videos to display well and stay competitive in the feed.
This is what Instagram CEO Adam Mosseri has said about Reels:
“Generally speaking, reels are more engaging than photos. We’ve tried to make photos more engaging by…carousels, allowing you to add music to them. These things can help, but on average, people like and comment and interact with reels more than they interact with photos and videos. And so if there is a video strategy to be had, I recommend trying.”
Common Instagram aspect ratio mistakes to avoid
Even if you use the recommended sizes for Instagram photos and videos, small mistakes in how you design and upload your content can still affect how it displays. These are the issues I see most often when reviewing social media posts.
Designing square-first visuals for a vertical grid
A lot of creators still design everything as square images. The problem is that the Instagram grid now prioritizes a 4:5 aspect ratio.
Square posts may look fine in the feed, but they appear cropped on your profile page. Over time, this creates an inconsistent grid and makes your content look less intentional.
If profile appearance matters, start with portrait images instead of adapting square designs after the fact.
Placing text too close to the edges
Text and key elements placed near the edges of an image are at risk of being cut off in the grid preview.
This happens because Instagram automatically crops content differently depending on where it’s displayed. What looks centered in the feed may not be fully visible on your profile.
A simple fix is to design with a safe zone. Keep important text, logos, and focal points closer to the center so they remain visible across all placements.
Mixing carousel sizes
Carousel posts follow the dimensions of the first image or video you upload.
If you mix portrait, landscape and square photos in the same carousel, Instagram will resize or crop the rest to match the first one. This often leads to awkward framing or smaller images.
To avoid this, use the same dimensions and aspect ratio for every slide in the carousel.
This matters even more when you consider performance. Carousels are one of the most effective post formats, with engagement rates at around 0.55% year over year. If you’re using them to reach new audiences, inconsistent sizing across multiple images can quietly hurt both how your content looks and how it performs.
Confusing feed video size with Reels size
Feed videos and Reels use different dimensions, even though both are vertical formats.
- Feed video posts: typically 1080 x 1350 px (4:5)
- Reels: 1080 x 1920 px (9:16)
Using the wrong size can affect how your video is displayed, especially in the feed or Reels tab. In some cases, your video may appear cropped or not fill the screen properly.
Using landscape when profile appearance matters more than feed
Landscape images and videos still have their place, especially for certain types of content.
However, they take up less vertical space on screen and are more likely to look smaller or less prominent when users scroll. On your profile grid, they can also disrupt the visual consistency of your layout.
If your goal is to create a clean, cohesive Instagram account, portrait posts usually perform better visually.
Use SocialBee’s Instagram grid preview to check how your posts will look before they go live. When you upload videos and images, SocialBee shows them in a grid layout that mirrors your profile display, including the 4:5 crop applied to each post.
This means you can quickly spot if text gets cut off, if elements aren’t centered, or if your layout looks inconsistent. You can then edit or replace the content before scheduling, so everything looks aligned and intentional once it’s published.
How to choose the right Instagram post size
Knowing the correct Instagram aspect ratio is useful, but choosing the right format depends on what you want your content to do.
- Use portrait (4:5) for most feed posts. It takes up more space on screen and looks best on the profile grid.
- Use square (1:1) when visual balance or symmetry matters, like product shots or centered designs.
- Use landscape (1.91:1 or 16:9) when width is essential, such as wide scenes or detailed visuals.
- Use Stories and Reels (9:16) when you want full-screen vertical impact and better visibility on mobile.
In most cases, portrait is the safest choice for both display and consistency.
Frequently asked questions
1. What is the best Instagram post size in 2026?
The best IG post size for feed posts is 1080 x 1350 px with a 4:5 aspect ratio. This format ensures your images and videos display correctly in both the feed and the profile grid without getting cropped.
2. Does Instagram still support square posts?
Yes, Instagram still supports square posts (1:1 aspect ratio). However, square images may appear cropped on your profile grid, since the platform now uses a 4:5 layout for previews.
3. Why do my Instagram posts look cropped on my profile?
Instagram applies a 4:5 crop to your profile grid, even if your original image uses a different aspect ratio. This means square and landscape posts can lose content on the sides when displayed on your profile page.
4. What aspect ratio is best for Instagram Reels and Stories?
The best aspect ratio for Instagram Reels and Stories is 9:16, with a recommended size of 1080 x 1920 pixels. This format fills the entire mobile screen and improves how the cover image appears, avoiding black borders.
5. Can I use the same dimensions for images and videos?
Yes, for feed video and image posts, you can use the same dimensions for both images and videos. A size of 1080 x 1350 px (4:5) works well for both and keeps your content consistent across your Instagram grid.
6. What is the recommended Instagram profile picture size?
The recommended size for an Instagram profile photo is 320 x 320 pixels with a 1:1 aspect ratio. Although it uploads as a square image, it’s displayed as a circle, so you should keep important elements centered to avoid them being cut off.
7. What are the recommended Instagram ad sizes?
Instagram ad sizes depend on the format you choose, but most follow the same dimensions as regular posts.
- Feed ads: 1080 x 1350 px (4:5) for portrait, 1080 x 1080 px (1:1) for square
- Story ads: 1080 x 1920 px (9:16)
- Reels ads: 1080 x 1920 px (9:16)
For best results, use high-resolution images and videos, keep key elements centered, and design for vertical viewing when possible.
Perfect your Instagram posts with the right sizes
Instagram’s move to a 4:5 grid changes how your content is seen at a glance. Posts that aren’t designed for this format can look cropped, misaligned, or less polished on your profile.
The fix is simple: design with how the images display in mind. Start with portrait dimensions, keep key elements centered, and stay consistent across your images and videos.
Once you do that, your grid starts to feel intentional instead of pieced together.
If you want to make this easier, SocialBee helps you plan content, preview, and schedule your Instagram posts in one place. You can create your content calendar, adjust it for the right formats, and publish everything automatically without jumping between tools.
