How to Post Multiple Images With Different Sizes to Instagram

On Instagram, it’s impossible to post a carousel — multiple photos or videos in one post that you swipe through — with multiple different aspect ratios. In this article, I'll show you how to do it by resizing your images.

How to Post Multiple Images With Different Sizes to Instagram

Carousels on social media in general are having a moment, including TikTok carousels and LinkedIn carousels. But they can’t quite match the comeback that Instagram carousels are having. Recent reports have shown carousels on Instagram are generating similar levels of engagement as Reels. You’ve likely noticed more photo carousels in your feed, too.

It’s a great time to share more photo content to Instagram using this format. Not only are carousels being pushed by the algorithm, because you're posting multiple pictures on Instagram at the same time, the reach is better.

Carousels offer multiple opportunities for followers to see your content in their feed, showing different images from the same post at different times. There are some limitations to Instagram carousels, though, specifically when it comes to sharing multiple photos of different sizes all together in one post.

Instagram allows you to publish up to ten videos and photos in a single carousel, but they all need to be the same aspect ratio. Otherwise, Instagram will automatically crop the image and you won’t be able to fit the whole photo in the post.

In this post, I’ll show you how to post multiple photos or videos with different sizes without cropping by first resizing the canvas.

How to make a carousel on Instagram with images of different sizes:

  1. Choose up to 10 photos and/or videos
  2. Choose an aspect ratio – either 4:5 or 1:1
  3. Resize the photos with an image resizer like Kapwing
  4. Create a new Instagram post
  5. Tap the “multiple” images icon and choose your photos/videos
  6. Post your carousel to Instagram with multiple photo sizes

That’s the tl;dr version of how to post multiple photos with different sizes as a carousel. Let’s get into the specifics as I walk you through it, step by step.

How to Post Multiple Pictures on Instagram with Different Sizes

To post multiple photos or videos with different sizes on Instagram, you need to use a tool to resize them first. To avoid cropping out content, add a neutral background so that all of the photos and videos have the same aspect ratio. The aspect ratios for carousel are the same as the standard Instagram image size: either 4:5 or 1:1.

I recommend a black background – most Instagram users have dark mode turned on, so the black will disappear into the platform interface.

Then, you can post multiple pictures in the carousel without cropping out or changing the size of your image.

Here’s a step-by-step tutorial on how to resize images and videos that with Kapwing, an online video resizer and image editor:

Step 1) Upload your photos/videos to Kapwing

Head to on your device and click Get Started. Open a new project and choose the “Start with a blank canvas” option. For an Instagram carousel, you want to choose an aspect ratio of either 4:5 or 1:1. I’ll be using a square canvas for this tutorial, since I want to post landscape and portrait orientation photos together.

One at a time, upload the photos or videos you want to post. Tap the Media button and then tap “Click to upload” to choose images on your device. You can also upload photos from a link or with the Google Drive integration if your photos or videos are stored in Google Drive, Google Photos, or elsewhere online.

Step 2) Add a black background

Before you add your photos and/or videos to the canvas, I recommend changing the color of the background to black. As mentioned previously, most users have their phones (and therefore their Instagrams) set to dark mode, so a black background will blend into the feed, making your content stand out, rather than distracting from it.

To change the background color from the default white background, tap the “Edit background” button above the canvas.

Then scroll down to the Background color options and choose black.

Step 3) Resize your photos and videos

This step is easy because you’re not manually resizing anything – no cropping, no stretching, no photoshop skills required. You’re just adding it to the canvas.

Open the Media tab again and select the photo or video you uploaded in the first step.

Tap the blue plus sign in the bottom right corner of the thumbnail. This will automatically add the photo or video to the canvas and center it on the background.

Here's what it will look like for a landscape image or video and a vertical image or video:

Step 4) Export and download your image or video

After resizing your posts, it’s time to download them to your device so you can share them on Instagram as a carousel. Since each photo/video now has a 1:1 aspect ratio (or 4:5, depending on what you chose), you can publish them without cropping.

Once you export, use the "Downloads" gallery to find the file you just made and save it to your phone.

If you're not signed into a Kapwing account, sign in or sign up using your Google account or preferred email address. Once you're signed in, each of your exports will be saved in your workspace so that you can download them later.

Repeat these steps for each of the photos and videos that you want to share in your Instagram carousel. After you've downloaded each of the resized posts, open the Instagram app and upload them as a single post.

To do so, open a new post and tap the multiple images icon that appears in the right hand corner beneath the image preview. Now you can select all the images and videos (up to ten) you want to include in your carousel.

Tap each of the resized posts in the order you want them to appear and share your post as normal.

How to Post One Long Image as Two Slides on an Instagram Carousel

The above tutorial is a great way to share multiple images and videos with different aspect ratios. For images with landscape orientation, though, especially panorama style images, it’s not always the best way to showcase the photo. You lose a lot of image quality by shrinking the photo down to fit into a square or 4:5 canvas.

There’s a quick solution, though.

To show the whole landscape image in your Instagram carousel, follow these steps:

Step 1) Center the landscape photo on a blank canvas

The first image in your carousel should be the whole photo. So following the previous tutorial for resizing photos, center your landscape photo on a black background. Instagram carousels allow for 4:5 or 1:1 aspect ratios. For this example, I’m setting the background to 4:5.

Save this new, resized photo to your device.

Step 2) Split your landscape photo in two

Add your photo to the canvas by tapping the blue plus icon on the thumbnail in the media tab. This will center the image on the canvas, but that’s not what you want.

Tap the “Edit image” button and select Crop. Because the canvas is 4:5, that’s the crop preset I’ve selected. If your canvas is a square, select 1:1.

Move the image within the crop preview so that the corners line up with one side of the image. For my image, this splits the photo exactly in two. You may need to adjust the line up slightly for your post, depending on how wide your landscape photos are.

Export and save this half of the photo as a single image.

To get the other half of the photo, scroll down on the download page and select “Edit this project.”

Once you’ve reopened the project, select “Edit image,” tap Crop, and move the image to center the other half of it within the crop preview. Export and save the second image.

Open a new post on Instagram and select the multiple images icon. Select the whole image with the black background first, then the two slides.

You’ll be able to preview what they’ll look like on the feed. It should look like a continuous image.

In the caption for the carousel, you can include a quick note encouraging viewers to swipe to see the whole image, although most users swipe on instinct when they see a carousel.

And that’s how you fit a long photo into a single carousel!
