What Are Instagram Carousel Posts?

Carousel posts are Instagram posts containing multiple images or videos that users swipe through horizontally. They appear in feeds with small dots at the bottom indicating how many slides are available.

Key Features (2026):

• Up to 20 photos or videos per post (increased from the previous 10-slide limit)
• Mix photos and videos in a single carousel
• All slides use the same aspect ratio (set by the first image)
• Users swipe left to view the next slide
• Built-in analytics track impressions and engagement per slide
• Carousels can include product tags for Instagram Shopping
• Reels clips can be added as carousel slides

Why Use Carousel Posts?

Increased Engagement

Carousel posts typically receive higher engagement than single-image posts. Multiple slides give users more reasons to interact.

Better Storytelling

Tell complete stories across multiple slides. Show before/after, step-by-step processes, or multiple product angles.

More Content Value

Pack more information into one post. Share multiple tips, showcase product features, or display event highlights.

How to Create an Instagram Carousel (Step-by-Step)

1. Open Instagram and tap the + icon to create a new post
2. Select multiple images by tapping the "Select Multiple" icon (stacked squares)
3. Choose up to 20 photos/videos in the order you want them displayed
4. Apply filters (optional) - you can apply the same filter to all or edit individually
5. Write your caption with relevant hashtags and a call-to-action
6. Tag products (if using Instagram Shopping)
7. Tap Share to publish your carousel

Mixed Media Tips

• All slides in a carousel share the same aspect ratio (determined by the first image)
• Test your carousel flow before publishing by previewing
• Videos auto-play on mute - add captions for accessibility
• Balance video and image content for variety
• Consider using the first slide as a "cover" and the last as a CTA

Common Carousel Mistakes

1. Weak First Slide

Your opening slide must grab attention immediately. Avoid boring or unclear first impressions.

2. Inconsistent Design

Jarring visual changes between slides distract users and break engagement flow.

3. Too Much Text

Instagram users scroll quickly. Keep text minimal and scannable.

4. No Clear Purpose

Each slide should add value. Remove filler content that doesn't support your main message.

5. Missing Call-to-Action

Tell users what to do next. Include clear next steps in your caption or final slide.

6. Ignoring Analytics

Use performance data to improve future carousels. Track what works and optimize accordingly.

Frequently Asked Questions

How many photos can you put in an Instagram carousel?

Instagram now allows up to 20 photos or videos in a single carousel post. This was increased from the original 10-slide limit. You can mix photos and videos within the same carousel.

What is the best size for Instagram carousel posts?

The recommended size for Instagram carousel posts is 1080 x 1080 pixels for square format or 1080 x 1350 pixels for portrait format. Portrait format (4:5 aspect ratio) is often preferred as it takes up more screen space in the feed.

Do Instagram carousels get more engagement?

Yes, carousel posts consistently outperform single-image posts for engagement. Studies show carousels deliver higher engagement rates, and Instagram has confirmed carousels can receive up to 1.4x more reach than single-image posts.

Can you edit an Instagram carousel after posting?

You can edit the caption and alt text of a carousel after posting, but you cannot add, remove, or reorder slides after the carousel is published. You also cannot change the images or videos themselves after posting.

What aspect ratio should I use for Instagram carousels?

Instagram carousels support three aspect ratios: square (1:1), portrait (4:5), and landscape (1.91:1). All slides in a carousel must use the same aspect ratio, which is determined by the first image you select.

How do I add music to an Instagram carousel?

You can add music to Instagram carousel posts by including video slides that contain audio. For photo-only carousels, you cannot add background music directly - this feature is only available for Reels.
