Instagram updates its layout and algorithm regularly, and image sizing recommendations shift with those updates. Using the wrong dimensions does not always break your post visually, but it affects how much screen space your content occupies in the feed and how the algorithm treats it. This guide covers every current format for 2026 with the specific dimensions that perform best right now.
Instagram Image Sizes for 2026
Profile photo: 320 x 320 pixels minimum, displayed as a circle. Upload at 400 x 400 or larger so it stays sharp on high-resolution and retina screens. Keep important elements centered since the circular crop removes the corners. A face or logo filling most of the frame works better than a wide shot with lots of negative space.
Square feed post: 1080 x 1080 pixels, a 1:1 ratio. This is the format Instagram was originally built around and it remains widely used. It works well for product shots, graphics, and any composition designed around a square frame.
Portrait feed post: 1080 x 1350 pixels, a 4:5 ratio. This is the format that currently gets the most real estate in the feed and measurably outperforms square in engagement metrics for most content types. More detail on why this matters below.
Landscape feed post: 1080 x 566 pixels, approximately a 1.91:1 ratio. Landscape gets the least feed space and tends to perform accordingly. Use it only when the horizontal composition is essential to what you are showing.
Stories: 1080 x 1920 pixels, a 9:16 full vertical ratio. Leave a safe zone of approximately 250 pixels at the top and bottom where Instagram's interface elements including the username bar, the reply field, and story navigation overlap the image.
Reels cover image: 1080 x 1920 pixels at 9:16. The cover shows in your profile grid as a cropped square, so the key visual element should be placed in the center of the frame. The top and bottom portions of a Reels cover will not appear in grid view.
Carousel posts: 1080 x 1080 for square or 1080 x 1350 for portrait. All images in a carousel should use the same dimensions to avoid jarring transitions between slides. The format of your first image sets the crop for the entire carousel.
Broadcast channel images: 1080 x 1080 pixels. Broadcast channels use square as the default for image posts.
The 4:5 Portrait Format and Reach
The 4:5 portrait format at 1080 x 1350 pixels is the highest-performing format for Instagram feed posts right now and has been consistently outperforming square for several years. The reason is simple and mechanical: a 4:5 portrait image takes up more vertical space on the screen than a 1:1 square. When a user is scrolling, they spend more time looking at taller content before it scrolls out of view.
Instagram's algorithm treats time-on-content as an engagement signal. A post that holds someone's attention for an extra half second because it is taller on the screen registers as higher engagement, which leads to more distribution. The content does not have to be better. The format advantage alone shifts the metrics.
If you are currently posting in square format and wondering why reach has plateaued, switching to 4:5 portrait for your next several posts is worth testing as a controlled experiment. Keep the content type consistent and change only the aspect ratio. Most creators see a measurable difference.
Safe Zones and Interface Overlap
Safe zones are the areas of your image guaranteed to be visible without interface elements overlapping them. On Instagram Stories and Reels, the top portion of the screen is covered by the user profile information and story progress bars. The bottom portion is covered by the reply field, the heart button, and the Instagram navigation bar.
For Stories and Reels at 1080 x 1920, keep text and important visual elements between approximately 250 pixels from the top and 400 pixels from the bottom. For feed posts there is no interface overlap in the image itself, but the like count, caption, and comment button appear directly below the image and can distract from a weak lower composition.
What Instagram Does With Your Metadata
Instagram strips most EXIF data during upload, including GPS coordinates. This is the behavior most people expect and assume. However, the stripping happens on Meta's servers after your file has been uploaded. Your original file with full GPS coordinates and device information travels to Meta's infrastructure before anything is removed.
For most creators this is an acceptable trade-off. But it is worth understanding that you are relying on Instagram's processing rather than controlling the data yourself. If you send the same photo directly to a brand partner via email or messaging for approval before posting, that file contains your full metadata including location.
Browser-based tools like Cropix strip the metadata locally before the file ever leaves your device. The files you download and then upload to Instagram are already clean. You are not depending on any platform's processing to protect your location information.
Preparing Images for Instagram and Every Other Platform
If you post the same photo to Instagram, TikTok, YouTube, Pinterest, and LinkedIn you need five different crops at different dimensions. Doing that manually adds ten to fifteen minutes to your posting workflow every time. Over a week of regular posting that time adds up to something worth solving.
Cropix generates all platform sizes in a single step. Drop your original photo in, select the platforms, download a ZIP with every correctly sized file. The 4:5 Instagram portrait, the 9:16 TikTok vertical, the 16:9 YouTube thumbnail, the Pinterest tall format. All at once, metadata stripped, ready to post.
File Format for Instagram
Instagram accepts JPEG, PNG, and WebP. JPEG at 80 to 90 percent quality is the most reliable choice for photos. PNG is appropriate for graphics with transparency or precise text. Keep file size under 8MB for photos and under 1MB for profile images.
Instagram recompresses images on upload regardless of the format you submit. Starting with a high-resolution original and exporting at good quality gives the platform more to work with and generally results in better final image quality in the feed.
