Trying to post a mix of landscape and portrait photos in an Instagram carousel feels like it should be simple, but it quickly turns into a cropping nightmare. You have a great collection of images - a wide scenic shot, a tall portrait, and a few detailed squares - but when you select them, Instagram forces everything into a single, awkward frame. This article provides a clear, step-by-step guide to bypass that frustration, allowing you to post both horizontal and vertical photos together in one seamless carousel post, no compromises necessary.
The root of the problem lies in how Instagram’s multi-photo posts are designed. When you create a carousel, the app locks the aspect ratio of the entire slideshow to the aspect ratio of the very first photo you select. This is a built-in limitation designed to create a smooth swiping experience, but it’s a major creative roadblock for photographers and content creators.
Here's how it plays out:
In short, you lose control. The carefully composed shot you took is re-framed by the app’s rigid rules. To get that control back, you need to prepare your photos before you ever open the Instagram app to post them.
The most effective way to combine different photo orientations is to make them all share the same final dimensions before uploading them. You do this by adding borders - also known as padding or "letterboxing" - to make every image conform to a single, consistent size. For example, you can fit a wide landscape photo into a tall portrait frame by adding blank space (like white or black bars) above and below it.
Your goal is to decide on a destination aspect ratio for the entire carousel and then edit each photo to fit that frame. For maximum impact on the Instagram feed, the 4:5 aspect ratio (a vertical/portrait orientation) is the best choice. It takes up the most vertical screen real estate on a phone, grabbing more attention as someone scrolls. A common pixel dimension for this is 1080 pixels wide by 1350 pixels tall.
So, the strategy is simple: turn every photo in your carousel set - whether it’s a portrait, landscape, or square - into a 1080x1350 pixel image. Here are a few ways to do it.
For most people, editing right on their phone is the fastest and most convenient option. Dozens of free apps can handle this task easily. Apps like InShot, Canva, Snapseed, and Adobe Lightroom Mobile's export settings are all excellent choices. While the specific button names may vary, the process is fundamentally the same across all of them.
Let's walk through the universal steps. For this example, we'll imagine we're using an app like InShot, which is particularly good for this specific task.
Once you’ve saved all your edited photos, simply go to Instagram, create a new post, select your images, and you'll find they flow together perfectly in the carousel preview with no weird cropping.
If you prefer editing on a larger screen or use software like Adobe Photoshop, Affinity Photo, or Canva's desktop app, you have even more control over the final result. The process is similar to the mobile method: you create a master canvas and fit each photo into it.
Photoshop gives you pixel-perfect accuracy, which is great for brand consistency and getting every detail just right.
File >, New. Set the dimensions to 1080 pixels for the Width and 1350 pixels for the Height. Set the resolution to 72 pixels/inch, which is standard for web images. File >, Place Embedded and select your image. Photoshop will place it on a new layer. File >, Export >, Save for Web (Legacy). Choose JPEG as the format and set the quality to around 70-80 for a good balance of quality and file size. Make sure the dimensions are still 1080x1350. Now that you know how to mix orientations, here are a few tips to make your carousels more effective and visually striking.
The first slide is your digital storefront - it has to convince someone to stop scrolling and start swiping. Since your padded photos all share the same dimensions, you have the freedom to pick any image to lead the carousel, be it landscape or portrait. Choose the one that is most thumb-stopping, tells the most intriguing part of the story, or has the strongest visual composition.
Don't just upload a random gallery, use the carousel format to build a narrative. The ability to mix orientations is a powerful storytelling tool.
Pacing is everything. By guiding the viewer from a grand scene to intimate details, you create a more engaging and immersive experience than a single photo ever could.
To make the carousel feel like a single, unified piece of content, keep your editing style consistent across all the photos. This means using the same color grading, white balance, and contrast levels. Applying the same Lightroom preset or filter to all the images before padding them is a great way to achieve this. The consistent edit, combined with your matching borders, will make even the most varied set of photos look intentionally curated.
Posting landscape and portrait photos together in an Instagram carousel is entirely possible with a little prep work. By deciding on a universal aspect ratio - ideally the screen-hogging 4:5 - and using a simple app or desktop software to add borders, you regain full creative control over your images. This way, you can build dynamic, story-driven posts that showcase your photography without falling victim to Instagram's automatic crop.
