Instagram Image Size Guide 2025 - Complete Dimensions for All Post Types

Published: January 20, 2025 | Updated: January 20, 2025

Instagram is one of the most popular social media platforms, with over 2 billion active users. To maximize engagement and ensure your content looks professional, it's essential to use the correct image dimensions for each post type. This comprehensive guide covers all Instagram image sizes for 2025.

Instagram Feed Post Dimensions

Instagram feed posts are the main content type on your profile. Here are the optimal dimensions:

  • Square Posts: 1080×1080 pixels (1:1 aspect ratio) - Best for most feed posts
  • Portrait Posts: 1080×1350 pixels (4:5 aspect ratio) - Takes up more screen space
  • Landscape Posts: 1080×566 pixels (1.91:1 aspect ratio) - Less common, but acceptable
  • Maximum file size: 30MB
  • Supported formats: JPG, PNG

Square posts (1080×1080) are the most versatile and work well in the Instagram grid. Portrait posts (1080×1350) take up more vertical space in the feed, making them more engaging but they may be cropped on some devices.

Instagram Story Dimensions

Instagram Stories are full-screen vertical content that disappears after 24 hours:

  • Recommended size: 1080×1920 pixels (9:16 aspect ratio)
  • Minimum size: 600×1067 pixels
  • Maximum file size: 30MB for photos, 4GB for videos
  • Safe zone: Keep important content in the center 80% to avoid UI elements

Stories are viewed on mobile devices in portrait orientation. Use our Instagram Story Cropper to ensure your images fit perfectly.

Instagram Reels Dimensions

Reels are short-form vertical videos, but cover images are important:

  • Cover image: 1080×1920 pixels (9:16 aspect ratio)
  • Video dimensions: 1080×1920 pixels (9:16 aspect ratio)
  • Maximum video length: 90 seconds
  • File size: Up to 4GB for videos

Reels cover images appear in your profile grid and in the Reels tab. Make sure they're eye-catching and represent your content well.

Instagram Profile Picture Size

Your profile picture appears as a circle on Instagram:

  • Recommended size: 320×320 pixels (minimum)
  • Optimal size: 1080×1080 pixels (square, 1:1 ratio)
  • Display size: 110×110 pixels on mobile, 180×180 pixels on desktop
  • Format: JPG or PNG

Since profile pictures are displayed as circles, use our Circle Crop Avatar Tool to ensure your image looks perfect when cropped.

Instagram Carousel Posts

Carousel posts allow multiple images in a single post:

  • All images must be the same aspect ratio - Mixing ratios causes cropping
  • Square (1:1): 1080×1080 pixels - Most common
  • Portrait (4:5): 1080×1350 pixels - Good for detailed content
  • Maximum images: 10 images per carousel
  • File size: Up to 30MB per image

Best Practices for Instagram Images

Follow these best practices to maximize engagement:

  1. Use high-resolution images: Always use at least 1080px width for feed posts to ensure sharp quality
  2. Maintain aspect ratios: Don't upload images that don't match recommended ratios - Instagram will crop them
  3. Optimize file size: While Instagram accepts up to 30MB, keep files under 2MB for faster uploads
  4. Consider your grid: Plan your feed layout. Square posts create a clean, uniform grid
  5. Test on mobile: Most users view Instagram on mobile - preview your images on a phone before posting
  6. Use safe zones: Keep important content away from edges, especially for Stories and Reels

Common Mistakes to Avoid

Avoid these common Instagram image mistakes:

  • Using incorrect aspect ratios: Images that don't match Instagram's ratios get cropped, potentially cutting off important content
  • Low-resolution images: Images under 1080px width appear pixelated and unprofessional
  • Mixing aspect ratios in carousels: All images in a carousel must have the same aspect ratio
  • Ignoring safe zones: Text or important elements near edges may be cut off on different devices
  • File size too large: Large files take longer to upload and may fail
