The Secret Trick: How To Post More Than 10 Pictures On Instagram (The 20-Photo Carousel Update)

Are you a content creator, photographer, or travel enthusiast who constantly hits the frustrating 10-photo limit on Instagram's carousel posts? For years, this restriction has forced users to choose their favorite moments or split compelling stories into multiple, less-engaging posts. The good news, as of late December 2025, is that a significant update has quietly begun rolling out, doubling the maximum capacity for your visual storytelling.

The days of being restricted to a mere 10 slides are over for many users. Instagram has been updating its platform to allow up to 20 photos or videos in a single, swipeable carousel post. While the rollout may not yet be universal, there are now two primary, powerful methods—one official and one creative workaround—to bypass the old limit and share your entire photo album in one go. We will explore both the new official feature and the best third-party app tricks.

The Official Way: Posting Up to 20 Photos in a Single Instagram Carousel

The most important and up-to-date information for 2025 is that the Instagram carousel limit has been officially doubled for a growing number of accounts. If you are still seeing the 10-slide restriction, ensure your app is fully updated, as this feature is part of a phased rollout. This change allows for far more detailed photo dumps, comprehensive tutorials, and richer event coverage, significantly boosting potential engagement on your multi-slide posts.

Step-by-Step Guide to the 20-Photo Post

The process is nearly identical to posting a standard carousel, but you will notice the selection counter now extends to 20:

• Open the Instagram App: Tap the plus (+) icon at the bottom of your screen to start a new post.
• Select the Carousel Icon: Tap the stacked squares icon (the multiple-photo icon) in the bottom right corner of the image preview.
• Choose Your Media: Navigate to your gallery. You can now select any combination of up to 20 photos and videos. As you select them, the counter in the corner will display the number, e.g., "15" or "20".
• Edit and Post: Tap "Next." You can apply filters to individual slides or the entire set, and you can rearrange the order of the images by long-pressing and dragging them.
• Write Your Caption: Craft a compelling caption and use relevant hashtags. Remember to use a strong Call-to-Action (CTA) like "Swipe to see the full transformation!" to encourage completion.

This feature is a game-changer for Instagram SEO and content strategy.

The Creative Workaround: Using Third-Party Apps for a Seamless Carousel (The "Hack")

If the official 20-photo limit has not rolled out to your account yet, or if you need to post even more than 20 images, the most effective "hack" is to use a third-party app to combine your photos into a single, long image or a video. This creates a visually stunning seamless carousel effect where the image flows perfectly from one slide to the next, a popular technique among professional creators.

The SCRL App Method (The Seamless Scroll)

The SCRL app (available on both iOS and Android) is the most popular tool specifically designed for this purpose. It allows you to create a continuous canvas that you can slice into individual slides, effectively creating a photo collage maker that breaks the traditional limits.

1. Design Your Canvas: Open the SCRL app and choose the "Carousel" or "Seamless Post" option.
2. Add Your Photos: Import all your desired photos (even 30 or more). Drag and drop them onto the canvas, arranging them in a visually appealing, continuous line.
3. Slice the Image: SCRL automatically slices the long image into the correct aspect ratio for Instagram slides (typically 1080x1080 pixels per slide).
4. Export and Post: The app will save the sliced images (usually 10 of them) to your phone's gallery.
5. Upload to Instagram: Go to Instagram, create a new carousel post, and select the 10 sliced images in their correct order. Because you have combined 20+ images into a single, long canvas, you have effectively bypassed the limit.

Other Photo Combining Tools

If SCRL isn't your preference, you can achieve a similar effect by using other powerful editing tools:

• Canva: Use Canva to create a very wide design (e.g., 10800px wide by 1080px tall for a 10-slide post). Design your content across the entire width, then use a separate app like Grid Post or an online tool to slice the final image.
• InShot / Mojo: These apps are excellent for combining multiple photos into a single video slideshow. By converting your 15+ photos into a 60-second video, you can post it as a single video post, completely bypassing the carousel picture limit. This is a great alternative for sharing a photo album or a quick video recap.

Advanced Strategies: Maximizing Engagement on Your Multi-Slide Posts

Posting more than 10 photos is only half the battle; ensuring your audience swipes through all 20 is the real challenge. High-performing carousels follow a strict storytelling arc and utilize specific visual cues to maximize the completion rate.

1. Master the Hook and the Payoff

A successful carousel is structured like a mini-story:

• Slide 1 (The Hook): This must be the most compelling image or a strong, curiosity-driven headline (e.g., "You Won't Believe What Happened on Slide 18"). This is your attention grabber.
• Slides 2-19 (The Value/Narrative): Deliver the content. Break down a complex topic into digestible steps, showcase a series of related products, or walk through a detailed tutorial. Use short paragraphs and large, readable text.
• Slide 20 (The Payoff/CTA): End with a strong conclusion and a clear Call-to-Action, such as "Save this post," "Share with a friend," or "Comment your favorite photo!"

2. Use Visual Cues and Design Elements

Because the new 20-slide limit is long, you need to actively guide the user's eye:

• Arrows and Lines: Explicitly use arrows or lines that visually extend from the right edge of one slide to the left edge of the next. This creates a psychological prompt to "Swipe for more".
• Consistent Branding: Maintain a consistent color palette, font style, and logo placement across all 20 slides. This builds brand recognition and keeps the post feeling cohesive, even with a high volume of images.
• Mixed Media: Don't be afraid to mix photos with videos and graphics. A short, high-quality video clip can break up the monotony of 20 static images and increase the time spent viewing the post.

By leveraging the new 20-photo limit or employing the creative seamless carousel workarounds, you can transform your Instagram content from a series of disjointed posts into a powerful, comprehensive visual journey. This is the key to mastering Instagram engagement and establishing stronger topical authority in your niche.
