The Complete Guide to Instagram Image Sizes and Dimensions for 2025

Getting Instagram image dimensions right is crucial for maximizing engagement and ensuring your content looks professional. Whether you're sharing personal stories or running ads for your brand, using the correct sizes prevents cropping issues and helps your content perform better in Instagram's algorithm.

This guide covers the essential Instagram dimensions you need to know, plus how Vibemyad can help you create perfectly sized content.

Instagram Post Image Sizes

Instagram posts can be square, landscape, or portrait format, and you can upload them in PNG, JPG, and BMP file formats. While all images appear square on your profile grid, clicking on photos displays them at their full aspect ratio.

Instagram Post Sizes

Square Posts

Dimensions: 1080 x 1080 pixels (1:1 aspect ratio)

Square images are Instagram's classic format and work best for:

• Product showcases
• Brand announcements
• Quote graphics
• Symmetrical designs

Square posts appear consistently across all parts of Instagram, making them ideal for maintaining brand consistency.

Vertical Posts

Dimensions: 1080 x 1350 pixels (4:5 aspect ratio)

Vertical posts take up more screen space and are perfect for:

• Fashion and lifestyle content
• Detailed product shots
• Portrait photography

These posts command more attention by requiring users to scroll longer, increasing engagement time.

Landscape Posts

Dimensions: 1080 x 566 pixels (1.91:1 aspect ratio)

Landscape format works well for:

• Wide scenic shots
• Product layouts
• Team photos
• Infographics

Instagram Carousels

You can upload up to 20 photos or videos in a carousel using any of the above dimensions. Remember: Instagram automatically crops all images to match the aspect ratio of your first photo.

Instagram Story Sizes

Dimensions: 1080 x 1920 pixels (9:16 aspect ratio)

Instagram Stories are viewed by over 500 million users daily. Sticking to the 9:16 ratio is crucial because Instagram will crop or zoom into content that doesn't fit, leading to quality loss and cut-off messaging.

Instagram Story Size

Stories work best for:

• Time-sensitive promotions
• Behind-the-scenes content
• Quick announcements
• User-generated content reposts

Pro tip: Keep important text and visual elements away from the edges to avoid cropping issues.

Instagram Reel Sizes

Dimensions: 1080 x 1920 pixels (9:16 aspect ratio)

Reels are Instagram's fastest-growing content format and follow the same dimensions as Stories. Reels can be 15 seconds to 15 minutes long and should be uploaded in MP4 or MOV format.

Instagram Reel Dimension

Key considerations for Reels:

• Use the full 9:16 vertical format for maximum impact
• Remember that Reels covers appear as 1:1 squares on your profile grid
• Keep important elements centered to avoid cropping in the profile view
• Choose an engaging cover photo at 1080 x 1920 pixels or select a frame from your video

Instagram Ad Sizes

Properly sized ads perform significantly better, with studies showing up to 23% higher engagement rates for optimally dimensioned content.

Instagram Ad Dimensions

Feed Ads
