Recently, Instagram rolled out significant modifications to its grid layout and overall design, aiming to enhance user engagement and content visibility. The new Instagram grid format supports dynamic sizing and offers greater flexibility for displaying various types of media. These changes are designed to keep the visual flow fresh and engaging, adapting to both mobile and desktop views. 

Key Takeaways:

• Instagram's 2025 dimension update includes significant changes to the grid layout and image dimensions for various types of Instagram posts, such as carousels, reels, and stories.

• High-resolution Instagram photos and videos ensure content looks professional and engaging across all devices.

• The new dimensions present an opportunity to try the different types of Instagram content to determine what resonates most with audiences.

Detailed Guide to Instagram Image Dimensions for 2025

Here’s a detailed breakdown of the new dimensions your content is required to be:

1. Carousel Posts

• Image Size: 1080 x 1350 pixels

• Grid View: 1012 x 1350 pixels

• Important Note: The center area of the image remains visible in the grid view, so it's crucial to place key elements within this space to ensure they are displayed when users browse the grid. This is best when you need to share multiple photos at the same size.

2. Reels

• Image Size: 1080 x 1920 pixels (This is a vertical format suitable for mobile viewing.)

• Grid View: 1080 x 1440 pixels

• Important Note: Text should be avoided at the top and bottom of the image in this format to prevent it from being cut off in the grid view.

3. Stories

• Image Size: 1080 x 1920 pixels (Again, optimized for vertical display.)

• Grid View: 1080 x 1610 pixels

• Important Note: Similar to Instagram Reels, avoid placing text at the top and bottom areas of the story image to ensure visibility in all viewing formats.

To keep up with these changes, follow Instagram’s official communications. Instagram suggests embracing these new dimensions of Instagram post sizes and Instagram story sizes by experimenting with different content forms. 

How to Optimize Your Instagram Posts for the New Dimensions

Several tools can help you adapt your content to meet the new Instagram image size requirements. Digital Stack offers updated templates and tools designed explicitly for Instagram's new dimensions. These resources create high-quality images and Instagram videos that adhere to the platform's latest standards. 

To maximize engagement with the new dimensions, consider the following tips:

1. Focus on Quality Over Quantity

With the improving screens on smartphones and other devices, higher-resolution images and videos are crucial. They ensure that your content and feed post look sharp and professional, regardless of the device used for viewing. Higher-resolution content also stands out more in the crowded 

Quality visuals are more likely to get a reaction, whether it's a like, comment, or share. Investing time in creating high-quality content rather than posting frequently but with lower quality builds a more engaged and loyal audience. For your Instagram profile picture size, while not technically a post, it's worth noting that there is a recommended size for your Instagram profile picture, too.

2. Use the Full Aspect Ratio for Instagram Stories

Utilising the full vertical aspect ratio (1080 x 1920 pixels) for Instagram Stories maximises screen space on mobile devices, making the content more immersive and engaging. When the entire screen is filled with visually compelling content, it grabs attention and can hold it longer, increasing the likelihood of viewer interaction.

This larger space allows for more creativity in storytelling on your Instagram feed. You can incorporate various elements like text, stickers, and links more effectively without cluttering the view. An immersive story experience can transport viewers, making them feel closer to the action or the narrative being presented. 

3. Test Different Types of Content

With new dimensions and format rules, it's a good opportunity to experiment with different types of content to see what performs best. This might include testing different social media image sizes, video sizes and lengths, square photos, or interactive elements like polls or swipe-up links in Instagram Stories. When you upload a Reel, you can choose a cover image, which acts as the thumbnail.

Use Instagram’s built-in analytics tools to track which types of content yield the best engagement rates, reach, and overall performance. Feedback from your audience in the comment section or direct messages provides insights into their preferences and reactions to different formats.
