Design Best Practices for Instagram Carousels
1. Consistent Aspect Ratios
Why it matters: Mixed aspect ratios in one carousel create awkward cropping and poor user experience.
Do:
- Use the same aspect ratio for all slides in one carousel
- Choose 1:1 (square) for maximum compatibility
Don't:
- Mix square and landscape images in one carousel
- Use aspect ratios not supported by Instagram
2. Image Quality & Resolution
Technical Requirements:
- Minimum resolution: 320 x 320 pixels
- Recommended resolution: 1080 x 1080 pixels
- Maximum file size: 30MB per image
- Supported formats: JPEG, PNG, GIF (non-animated), BMP, TIFF
- Color space: sRGB recommended for best display
3. Content Flow & Storytelling
Slide 1: Hook Grab attention immediately. Use bold visuals, intriguing text, or compelling imagery.
Slides 2-8: Value Deliver on your promise. Provide tips, showcase products, or tell your story progressively.
Final Slide: Call-to-Action End with a clear CTA. Ask for engagement, direct to your bio, or prompt specific actions.
Platform-Specific Considerations
Feed Display
Your carousel's first slide is crucial as it appears in the Instagram feed. Make sure it:
- Works as a standalone image
- Clearly indicates it's part of a series
- Includes engaging visual elements
- Has readable text (if using text overlays)
Stories & Reels Integration
- Carousel posts can be shared to Stories (individual slides)
- Consider how each slide looks when shared separately
- Include your handle/branding on important slides
- Design slides to work both in carousel and standalone contexts

Common Instagram Carousel Size Mistakes
❌ Mistake #1: Mixed Aspect Ratios
Using different aspect ratios within one carousel causes Instagram to crop images awkwardly, cutting off important content.
❌ Mistake #2: Low Resolution Images
Uploading images smaller than 1080px results in pixelated, unprofessional-looking carousels that hurt engagement.
❌ Mistake #3: Ignoring Safe Zones
Not accounting for Instagram's interface elements (like the slide indicator dots) can obscure important content.
❌ Mistake #4: Too Many Slides
Using all 10 slides without strategic purpose leads to viewer fatigue and lower completion rates.
