The great news is that, as of late 2024 and fully rolling out into December 2025, the platform has officially doubled the capacity of its carousel feature, fundamentally changing how you can share your content.

This comprehensive guide will walk you through the new, expanded limit, show you the exact steps to create a 20-slide post, and reveal advanced strategies for those who need to share even more content or are still stuck on the old system. The days of splitting your story into multiple, confusing posts are over—it's time to leverage the power of the 20-photo Instagram carousel.

Key Facts: The New Instagram Carousel Limit in 2025

The most crucial piece of information for any content creator in 2025 is the official increase in the Instagram carousel post limit. This update is a game-changer for digital storytelling and content depth. Here is a breakdown of the current limits and technical specifications you need to know.

• Maximum Slides (Photos/Videos): The official limit has been doubled from 10 to 20 items (photos or videos) per single carousel post.
• Content Types: The 20-slide limit applies to a combination of both static images (photos) and short-form videos.
• Rollout Status: The feature began rolling out in 2024 and is now widely available globally in December 2025. However, some users or older app versions may still be on the 10-slide limit, requiring an app update.
• Aspect Ratios: All photos and videos within a single carousel must maintain the same aspect ratio (e.g., all 1:1 square, all 4:5 vertical, or all 16:9 horizontal). The first item you select sets the ratio for the entire post.
• Video Length: Each video slide in the carousel can be up to 60 seconds long.

This expansion to 20 slides offers enhanced storytelling capabilities, allowing for more detailed tutorials, comprehensive event coverage, and deeper product showcases. It's the official answer to "how to add more than 10 pictures to an Instagram post."

How to Post Up to 20 Photos on Instagram: A Step-by-Step Guide

The process for creating a 20-slide carousel post is nearly identical to the old 10-slide method, but with one critical difference: the selection limit is now higher. If you are still seeing a limit of 10, make sure your Instagram app is updated to the latest version on both iOS and Android.

Step 1: Start a New Post

Open your Instagram app and tap the plus icon (+) at the bottom or top right of your screen to create a new post. Select "Post" from the options.

Step 2: Activate the Multi-Select Feature

On the photo selection screen, you must tap the multi-select icon. This icon typically looks like two overlapping squares or a numbered square, depending on your device and the current app version. Tapping this icon allows you to choose multiple media files.

Step 3: Select Your Content (Up to 20)

Navigate to your photo gallery. Begin tapping the photos and videos you wish to include. As you select them, a small number will appear on each file, indicating its order in the carousel. You can now select up to 20 items. If you still see the counter stop at 10, immediately check for an app update in the App Store or Google Play Store.

Step 4: Edit, Filter, and Reorder

Once you have selected all your media, tap "Next." You will be taken to the editing screen. Here, you can:

• Apply Filters: You can apply a single filter to all 20 slides or edit each slide individually.
• Reorder Slides: Press and hold a slide at the bottom of the screen to drag and drop it into a new position.
• Crop/Adjust: Ensure all slides maintain the same aspect ratio (set by the first slide).

Step 5: Finalize and Share

Tap "Next," write your caption, add relevant hashtags (LSI keywords like instagram carousel tips, multi-slide post strategy, and content batching are great here), tag people, and add a location. Finally, tap "Share" to publish your extended 20-slide masterpiece.

Advanced Strategies: Going Beyond the 20-Photo Limit

While 20 slides is a significant increase, some creators—such as those documenting massive events, intricate DIY projects, or detailed travel logs—may still find this limit restrictive. The key to posting more than 20 pictures on Instagram requires a shift in content format from a static post to a dynamic video format or a creative grid layout. This is where your topical authority truly shines.

1. The Reel Compilation Technique (Unlimited Content)

The most effective way to share a massive collection of photos is by converting them into an Instagram Reel. Reels have a maximum length of 90 seconds, which allows for a rapid-fire slideshow of many more than 20 images.

• How to Execute: Use a video editing app (like CapCut, InShot, or even the native Instagram Reels editor) to compile 30, 50, or even 100 images into a fast-paced video. Allocate about 0.5 to 1 second per photo.
• Key Entities: Use trending audio, add engaging text overlays, and use a strong call-to-action in the caption to maximize engagement. This is perfect for photo dump videos and travel recaps.

2. The Multi-Post Grid Strategy (Cohesive Gallery)

For a permanent, high-impact presentation on your profile, you can use the multi-post grid strategy. This involves breaking your content into multiple, sequential carousel posts, but linking them visually or thematically.

• How to Execute: Create three separate 20-slide carousel posts (totaling 60 photos). Post them one after the other. In the caption of Post 1, direct users to "Swipe to Post 2 on my profile!" In Post 2, direct them to Post 3.
• Key Entities: Ensure the first slide of each post has a strong visual connection or numbering (e.g., "Part 1 of 3," "Post 2/3"). This strategy builds topical authority around a large subject.

3. The Photo Collage Slide (Maximizing Single Slides)

If you absolutely must keep everything in a single 20-slide carousel, you can maximize the content of each slide by using photo collage apps.

• How to Execute: Before uploading to Instagram, use an app like Layout or Canva to combine 2 to 4 related photos into a single, high-resolution image. This effectively turns your 20-slide carousel into a 40- to 80-picture presentation.
• Key Entities: This technique is highly effective for before-and-after comparisons, product feature showcases, and mood boards, as it keeps related images grouped together.

By understanding the new 20-slide limit and employing these creative workarounds, you can master the art of sharing extensive visual narratives on Instagram, keeping your audience engaged and your profile content-rich.
