How to post multiple photos on Instagram
Posting multiple photos on Instagram creates a carousel post — the highest-engagement format on the platform. Here's how to do it in 2026.
Step-by-step instructions
- Open Instagram and tap the + button at the bottom
- Tap Post (not Story or Reel)
- Tap the multiple photos icon (overlapping squares) in the bottom-right of the photo picker
- Select up to 20 photos or videos in the order you want them
- Tap Next, apply filters or edits to each photo
- Write your caption, add hashtags, and tap Share
That's it — your followers can now swipe through all your photos.
How many photos can you post in one Instagram carousel?
Instagram allows up to 20 photos or videos in a single carousel post. This was increased from the original limit of 10 slides in 2024.
For best engagement, data shows that 5-10 slides is the sweet spot. Enough content to provide value without losing your audience's attention.
Best photo sizes for Instagram carousels
| Format | Size | When to use |
|---|---|---|
| Portrait (recommended) | 1080 x 1350px | Takes up most screen space |
| Square | 1080 x 1080px | Classic look |
| Landscape | 1080 x 566px | Panoramic shots |
Pro tip: Use portrait (4:5) ratio — it takes up 25% more screen space than square, which means more attention on your post.
Tips to get more engagement on multi-photo posts
1. Make the first photo count
Your first slide is what appears in the feed. Use a bold headline, striking image, or curiosity-driven hook to get people to swipe.
2. Tell a story across slides
Don't just dump random photos. Create a narrative: before/after, step-by-step, or a progression that rewards swiping.
3. Mix photos and text slides
Combine images with text-based slides to make your carousel educational. Educational carousels get more saves — the strongest algorithm signal.
4. Add a CTA on the last slide
End with a clear call to action: "Save this for later", "Share with someone who needs this", or "Follow for more tips".
5. Add audio for extra reach
When you post a carousel with a trending audio track, it also appears in the Reels tab, giving you exposure in two places at once.
The faster way: Use AI to create carousel posts
Instead of designing each slide manually, you can use InstaCarousel to generate professional carousel posts from any text in seconds.
- Paste your content (blog post, tips, thread)
- AI creates beautiful slides automatically
- Download and post to Instagram
You can also use our Text to Carousel tool or Image Splitter to create grid-style carousel posts.
Common questions
Can you add photos to an existing carousel?
No. Once a carousel is posted, you cannot add more photos. You'd need to delete and repost.
Can you rearrange photos after posting?
No. The order is set when you post. Plan your order before sharing — our Grid Maker can help you preview layouts.
Do carousels show up in Reels?
Carousels with audio can appear in the Reels tab, which significantly increases reach. Add a trending audio track when posting.
