Instagram Post Size in Pixels: Complete Guide 2026

The Ultimate Guide to Instagram Post Sizes in Pixels (2026 Edition)

Whether you are a seasoned content creator, a social media manager, or a business owner looking to elevate your brand, nailing your visual dimensions is everything. Nothing kills the impact of a stunning photo or a creative graphic faster than Instagram automatically cropping out crucial details or reducing your crisp image to a blurry, pixelated mess.

Instagram supports a variety of formats—from traditional squares to immersive vertical reels. To make sure your content always looks sharp and professional, here is your complete, up-to-date guide to Instagram post sizes in pixels.

1. Instagram Feed Posts

The grid is your digital storefront. While Instagram traditionally forced every photo into a 1:1 square, you now have plenty of flexibility.

• Square Posts (1:1 Aspect Ratio):
  • Recommended Size: $1080 times 1080$ pixels
  • Best for: Classic product shots, symmetrical photography, and clean graphic design.
• Portrait / Vertical Posts (4:5 Aspect Ratio):
  • Recommended Size: $1080 times 1350$ pixels
  • Best for: Maximizing screen real estate in the feed. Portrait posts take up more visual space as users scroll, making them the gold standard for engagement.
• Landscape / Horizontal Posts (1.91:1 Aspect Ratio):
  • Recommended Size: $1080 times 566$ pixels
  • Best for: Cinematic landscape photography. (Note: Instagram will crop square or vertical images to fit this ratio if you choose landscape, so it’s best to upload them pre-formatted).

💡 Pro Tip for the Grid: While you can post landscape images, portrait (4:5) and square (1:1) formats dominate the mobile screen experience and generally yield higher engagement rates.

2. Instagram Stories and Reels

Vertical, full-screen content is where the vast majority of daily engagement happens. Both Stories and Reels share the exact same canvas dimensions.

• Dimensions: $1080 times 1920$ pixels
• Aspect Ratio: 9:16
• Best for: Immersive video content, behind-the-scenes clips, tutorials, and announcements.

Safe Zones Matter:
When designing Stories or Reels, remember that Instagram overlays interactive elements like your profile name, caption text, like/comment buttons, and music stickers. Keep your essential text and core visuals centered and avoid placing critical information within the top 250 pixels and bottom 250 pixels of the frame so they don’t get blocked by UI elements.

3. Instagram Carousels

Carousels allow you to share up to 10 images or videos in a single swipeable post.

• Recommended Size: Keep every slide the exact same dimension—either $1080 times 1080$ pixels (square) or $1080 times 1350$ pixels (portrait).
• Best for: Step-by-step tutorials, before-and-after transformations, photo dumps, and multi-slide infographics.

🛠️ Pro Tip for Seamless Carousels: If you want to create a panoramic image that stretches continuously across multiple slides, calculate your width by multiplying 1080 by the number of slides you want (
