Size Matters: Instagram’s New Dimensions
Instagram continues to evolve, and staying on top of the platform’s new dimensions is crucial for creators and businesses alike. Keeping your content looking its best means understanding the optimum sizes for various post types. While the standard square post remains a cornerstone, Instagram also supports landscape and portrait orientations. For single image and video posts, the ideal aspect ratios are typically 1:1 (square), 4:5 (portrait), and 1.91:1 (landscape). Recently, Instagram has been testing and rolling out subtle adjustments to how content is displayed, emphasizing taller aspect ratios in the main feed to better fill the screen on mobile devices. This shift encourages the use of portrait-oriented content to maximize visual impact and user engagement.
Yes, photo size matters on Instagram or any other social network. This is a key factor to:
- Attract your followers’ attention
- Create a brand and build a community
- Make striking ads to attract more clicks
Good quality images, not pixelated and properly cropped, will help you gain more followers and keep the existing ones.
2025 Instagram Grid Changes
You may have noticed recent Instagram grid changes affecting how your profile page appears. While the traditional three-column grid has been a long-standing feature, Instagram is experimenting with different layouts and the way previews are cropped. These changes often aim to provide a more immersive and visually cohesive profile experience. Here is a list of grid changes that were made in 2025:
- Taller grid images for better mobile compatibility: You can now customize thumbnails to show the part of the photo you want to be displayed in the grid.
- Highlights moved to the grid: You can now find highlights in a separate grid tab, rather than above, which caused the grid to be pushed further down the page.
Instagram Grid Changes Coming Soon
The changes don’t stop there! Instagram’s CEO @mosseri also announced the following changes that the platform hopes to roll out this year:
- Edit your grid: You’ll soon be able to drag your photos around to reorder your grid however you like.
- Post directly to grid: You will be able to choose to post photos to your grid without adding them to the feed.
Understanding these grid dynamics is important for planning your overall profile aesthetic and ensuring that key visual elements of your posts are still visible in the thumbnail previews. Keeping abreast of these platform updates ensures your content not only looks fantastic when viewed individually but also contributes effectively to your overall Instagram presence.
