This update makes content sharing on the platform more natural and practical for both professional content creators and individual users.
Why Is the 3:4 Format Important?
Instagram has introduced a significant change in photo sharing by starting to support images with a 3:4 aspect ratio. This change is especially important because many smartphones use the 3:4 format as the default camera setting. Previously, Instagram only accepted portrait photos with a maximum ratio of 4:5, which meant that 3:4 images were either cropped or shared with blank space added at the top and bottom.
With this new update, Instagram users can now share their photos directly without the need for resizing or editing. This is a great convenience for professional photographers, content creators, and mobile photography enthusiasts. Users can now preserve the original composition of their photos and share them exactly as they were taken.
Instagram Adds 3:4 Support to Carousels and Profile Grids
The update doesn’t only apply to single image posts, but also includes multi-photo (carousel) posts. This means users can share multiple photos while keeping each image in its original form. Additionally, this update affects the profile grid: 3:4 portrait images will now be displayed without being squeezed into a square format or cropped at the edges.
Instagram’s decision is seen as part of its gradual shift away from the traditional square format towards a more flexible and user-friendly sharing experience. Especially for users who shoot with their phone cameras, this change makes content creation more practical and visually satisfying.
In conclusion, Instagram’s support for 3:4 aspect ratio photos is a major step forward in improving the user experience. This update eliminates the time-consuming need for photo editing, allowing content to be shared more naturally, with higher quality and authenticity.

Why Are Instagram Post Dimensions Important?
On Instagram, post dimensions are a key factor in the visual impact of your content. With the rise of mobile device usage, vertical formats have become more prominent in social media visuals. As of 2025, the platform’s supported dimensions have evolved, allowing users to present their content in a more attention-grabbing way.
Vertical posts take up more screen space, making them more likely to capture viewers’ attention. For this reason, content creators and brands aim to prepare their visuals according to these new dimensions to boost engagement rates. Portrait format, especially in reels, stories, and photo posts, enhances the visual user experience.
Being aware of current dimensions and ratios ensures higher-quality visuals and eliminates the need for additional editing. With Instagram now supporting more flexible formats like 3:4, the rigid constraints of the square format have been removed, offering a more creative and liberated content production process.
In summary, using the right post dimensions on Instagram is essential for brands, content creators, and individual users. Taking advantage of the vertical format offers both aesthetic and engagement benefits, making it a strategic choice for success on social media.
