Instagram Carousel Dimensions: Your Ultimate Guide for 2024

In the visually driven world of Instagram, carousels have become a powerful tool for storytelling, product showcases, and engaging content series. But to make your carousels truly shine, you need to nail the dimensions. Let's explore the perfect sizes for Instagram carousels and how to leverage them for maximum impact.

The Golden Ratio: Instagram's Preferred Dimensions

Instagram recommends the following dimensions for carousel posts:

  • Aspect Ratio: 1:1 (square), 4:5 (portrait), or 16:9 (landscape)
  • Recommended Resolution: 1080 x 1080 pixels (1:1), 1080 x 1350 pixels (4:5)
💡 Pro Tip: While Instagram supports various aspect ratios, the 1:1 square Format ensures consistency across all slides and looks excellent in feed and profile grid views.

Breaking Down the Options

Square Format (1:1)

  • Dimensions: 1080 x 1080 pixels
  • Pros:
    • Consistent look in feed and profile
    • Easy to create and repurpose content
  • Cons:
    • There is less vertical space for content

Portrait Format (4:5)

  • Dimensions: 1080 x 1350 pixels
  • Pros:
    • More vertical space for content
    • Takes up more screen real estate in the feed
  • Cons:
    • It may be cropped in the profile grid view

Landscape Format (16:9)

  • Dimensions: 1080 x 608 pixels
  • Pros:
    • Ideal for cinematic visuals or comprehensive infographics
  • Cons:
    • It takes up less space in the feed
    • It may not be as engaging on mobile devices

Best Practices for Instagram Carousel Dimensions

  1. Consistency is Key: Use the same aspect ratio for all slides in your carousel.
  2. Mind the Margins: Leave a safe zone of 250 pixels from the edges to ensure no critical content is cut off.
  3. Text Readability: Keep text size at least 40 pixels for headlines and 24 pixels for body text.
  4. File Size Matters: Each image should be under 30MB to ensure quick loading.
  5. Number of Slides: Instagram allows up to 10 slides per carousel. Use them wisely!

Designing for Impact: Beyond Dimensions

While dimensions are crucial, here are some additional tips to make your carousels pop:

Use a Cohesive Color Scheme

Create a visual thread that ties all slides together. This could be:

  • A consistent background color
  • A recurring design element
  • A color palette that aligns with your brand

Leverage White Space

Make sure never to overcrowd your slides. Embrace white space to:

  • Improve readability
  • Draw attention to critical elements
  • Create a clean, professional look

Create a Visual Flow

Guide your audience's eye from one slide to the next:

  • Use arrows or other directional elements
  • Number your slides
  • Create a story that naturally progresses

Optimize for Mobile

Remember, most users will view your carousel on mobile:

  • Use large, readable fonts
  • Keep text concise
  • Ensure images are clear and high-quality, even on small screens
