When you share multiple photos in a single Threads post, the platform groups them into a swipeable carousel. Knowing the exact limit helps you plan your content without hitting an upload error. Threads currently allows up to 10 images per carousel post, matching the limits of Instagram and many other social platforms. This article explains the carousel feature, the step-by-step process for adding multiple photos, and common mistakes to avoid.
Key Takeaways: Threads Image Carousel Limits
- Maximum 10 photos per carousel: You can select up to 10 images from your camera roll in a single post.
- Minimum 2 photos required: A carousel needs at least two images to activate the swipeable format.
- No video and photo mixing: You cannot combine videos and still images in the same carousel post.
Threads Carousel Feature Overview
The Threads carousel feature lets you attach multiple images to one post. Followers swipe or tap to view each image in sequence. The feature works on both the mobile app and the web version, though the upload process differs slightly between platforms.
Threads uses the same media picker as Instagram. This means the 10-image limit is inherited directly from Instagram’s carousel system. You cannot exceed this number through any workaround or third-party tool.
Each image in the carousel maintains its original aspect ratio. Threads does not crop or resize your photos during upload. However, the platform displays images in a vertical scroll on the web and a horizontal swipe on mobile. For best results, use images with the same orientation, either all portrait or all landscape.
How Many Photos Can You Add to a Threads Carousel
The maximum number of photos you can add to a single Threads carousel post is 10. This limit applies to both the iOS and Android apps as well as the web interface at threads.net.
The minimum number required to create a carousel is 2. If you select only one image, it posts as a standard single-image post without the swipeable carousel format.
Threads does not currently support carousels that mix photos and videos. If you need to share both media types in one post, you must post them separately.
Steps to Create a Carousel Post on Threads
- Open the Threads app or website
Launch the Threads app on your mobile device or go to threads.net in a browser. Make sure you are logged into your account. - Tap the compose button
On mobile, tap the pen-and-paper icon at the bottom of the screen. On the web, click the text box labeled “What’s happening?” at the top of the feed. - Tap the image icon
Look for the photo icon, usually shaped like a mountain or a square. On mobile, it appears below the text input area. On the web, it is a small icon next to the text box. - Select multiple images from your camera roll
Your device’s photo picker opens. Tap each image you want to include. A checkmark appears on selected images. You can select up to 10 images. The order you tap them is the order they appear in the carousel. - Tap Add or Done
After selecting your images, tap the Add button on iOS or the Done button on Android. On the web, click Open after selecting files from your computer. - Write your caption and post
Type your text caption in the compose area. You can tag people, add hashtags, or include links. Tap the Post button to publish the carousel.
Common Mistakes and Limitations
“I cannot select more than 10 images”
The Threads photo picker grays out or hides the selection checkbox after you have chosen 10 images. This is the hard limit. You cannot bypass it by using a third-party app or by posting multiple carousels in a single thread reply.
“My carousel shows images in the wrong order”
The order of images in your carousel is determined by the order you tap them during selection, not by the order in your camera roll. To reorder images, you must deselect all and reselect them in the correct sequence. There is no drag-and-drop reorder option on Threads.
“I tried to mix a video with photos, but only the video appears”
Threads carousels support only one media type per post. If you select a video and any still images, the video replaces the carousel entirely. The post becomes a single video post. To share both types, create a separate photo carousel and a separate video post.
“Carousel images look stretched or cropped on the web”
Threads displays carousel images in a vertical column on the web version. If your images have different aspect ratios, the column height changes for each image. For a consistent look, crop all images to the same aspect ratio before uploading. Square images 1080×1080 pixels work best across both mobile and web.
Threads Carousel Limits Compared to Other Platforms
| Item | Threads | |
|---|---|---|
| Maximum photos per carousel | 10 | 10 |
| Minimum photos for carousel | 2 | 2 |
| Video and photo mixing allowed | No | No |
| Drag-and-drop reorder | No | Yes |
| Maximum video length in carousel | N/A (no video carousels) | 60 seconds per clip |
Threads and Instagram share the same 10-image limit because they use the same media infrastructure. Instagram offers drag-and-drop reordering, which Threads currently lacks. Threads does not support video carousels at all, while Instagram allows up to 10 video clips in a carousel.
You can now create carousel posts on Threads with up to 10 photos. Plan your image order before selecting them since reordering is not available. For a professional look, use images with the same aspect ratio and orientation. If you need to share more than 10 photos on the same topic, consider posting a thread of multiple carousel posts in sequence.
