The Complete Guide to Instagram Photo Sizes in 2026
Instagram remains one of the most visually driven social media platforms in 2026, with over two billion monthly active users scrolling through their feeds every day. Whether you are a creator, a small business owner, or a brand marketer, getting your Instagram photo dimensions right is one of the simplest yet most impactful things you can do to improve the quality of your content. Uploading an image at the wrong size leads to compression artifacts, unexpected cropping, and a generally unprofessional look -- all of which can drive potential followers away before they even read your caption.
This guide covers every Instagram image size you need to know in 2026, from feed posts to stories to profile pictures, along with practical tips for making your photos look their absolute best.
Instagram Square Post Size: 1080 x 1080 Pixels
The square post is the original Instagram format and remains one of the most widely used. At 1080 x 1080 pixels with a 1:1 aspect ratio, square posts display perfectly in the feed and create a uniform, aesthetically pleasing profile grid. This format works particularly well for product shots, quote graphics, food photography, and any content where you want a balanced, centered composition.
While Instagram technically supports images as small as 320 x 320 pixels for square posts, uploading at the full 1080-pixel resolution ensures your image looks sharp on all devices, including high-density Retina displays. If you upload a larger image, Instagram will downscale it to 1080 pixels wide, which is fine -- but starting with an image that is already the correct size gives you the most control over how the final result looks.
Instagram Portrait Post Size: 1080 x 1350 Pixels
The portrait format at 1080 x 1350 pixels (4:5 aspect ratio) is widely considered the best format for maximizing engagement on Instagram in 2026. The reason is simple: portrait posts take up significantly more vertical space in the feed compared to square or landscape images. More screen real estate means more time your content is visible as someone scrolls, which increases the chance they will stop to engage.
Many professional Instagram marketers and influencers have shifted almost entirely to portrait-format posts for this reason. This format is ideal for full-body outfit photos, vertical product displays, infographic-style educational content, and any image where extra height improves the composition. Keep in mind that the portrait post will be cropped to a square in your profile grid, so make sure the most important visual elements are centered.
Instagram Landscape Post Size: 1080 x 566 Pixels
Landscape posts at 1080 x 566 pixels (1.91:1 aspect ratio) are the widest format Instagram supports for feed posts. While less common than square or portrait formats, landscape orientation is perfect for wide panoramic shots, group photos, cinematic-style imagery, and real estate or travel photography where a wide field of view adds impact.
The trade-off with landscape posts is that they take up less vertical space in the feed, which means users may scroll past them more quickly. They also appear with bars above and below the image on most screens. Despite this, landscape posts can be very effective when the content naturally suits a wide composition. For your profile grid, landscape images will be center-cropped to a square, so keep key elements away from the far left and right edges.
Instagram Story and Reels Cover Size: 1080 x 1920 Pixels
Instagram Stories and Reels covers use the full-screen vertical format at 1080 x 1920 pixels (9:16 aspect ratio). This is the same resolution as a standard smartphone screen in portrait orientation, which means your image or graphic fills the entire display without any bars or cropping when viewed on a phone.
For Stories, this size is essential for both photo and graphic-based content. Leave a safe zone of about 250 pixels at the top and bottom to account for the username bar and reply area that Instagram overlays on Stories. For Reels covers, this dimension ensures your cover thumbnail looks sharp and well-composed. A compelling Reels cover can significantly increase tap-through rates, as it serves as the visual preview on your profile grid and the Reels tab.
Instagram Profile Picture Size: 320 x 320 Pixels
Your Instagram profile picture is displayed at 320 x 320 pixels on the web and at 110 x 110 pixels on mobile devices. It is uploaded as a square but rendered as a circle, which means the corners of your image will be clipped. To get the best result, center your face or logo in the middle of the frame and leave adequate padding around the edges so nothing important is cut off by the circular mask.
Even though the display size is relatively small, uploading a higher-resolution image (at least 320 x 320) helps maintain sharpness. Your profile picture appears next to every post, comment, and story you publish, so it is worth taking the time to make it look crisp and recognizable at small sizes.
Image File Format and Quality Tips for Instagram
Instagram accepts JPG, PNG, and WebP image formats, though JPG is the most commonly used for photography. For images with flat graphics, text overlays, or logos, PNG tends to produce sharper results because it avoids the compression artifacts that sometimes appear in JPG files around sharp edges and text.
Instagram compresses all uploaded images regardless of format. To minimize visible quality loss, follow these guidelines:
- Upload at the exact recommended resolution rather than a drastically larger or smaller size. This gives Instagram less reason to resize and recompress your image.
- Keep file sizes under 1MB when possible. Larger files undergo more aggressive compression on upload.
- Avoid re-saving JPG images multiple times before uploading, as each save cycle introduces additional compression artifacts.
- Export from your editing software at 95-100% quality for photos and use PNG for graphics with text.
Instagram Photo Best Practices for 2026
Beyond getting the dimensions right, there are several strategies that can help your Instagram photos perform better in 2026:
- Use portrait format (4:5) for maximum feed visibility. This format occupies the most screen space, keeping your content in view longer as users scroll.
- Design with the grid in mind. Every feed post appears as a square thumbnail on your profile grid. Make sure the center of your image contains the key visual element so it looks good in both the feed and the grid.
- Maintain a consistent visual style. Whether it is a specific color palette, filter, or composition technique, consistency builds brand recognition and makes your profile more visually appealing to new visitors.
- Test on mobile before posting. The vast majority of Instagram usage happens on phones. What looks great on a desktop monitor may appear differently on a smaller screen.
- Use carousels to boost engagement. Multi-image carousel posts allow you to include multiple crops or angles of the same subject, and Instagram algorithm tends to show carousel posts more than once if a user does not engage the first time.
Common Mistakes When Resizing for Instagram
Even experienced content creators make these errors when preparing images for Instagram:
- Uploading screenshots or low-resolution images that look acceptable on your phone but appear grainy or pixelated on larger devices or high-density screens.
- Using landscape orientation for every post when portrait format would give you significantly more visibility in the feed.
- Ignoring the profile grid crop. All posts appear as square thumbnails on your profile regardless of their original aspect ratio. Important content at the very top or bottom of a portrait image may get cropped in the grid view.
- Not accounting for Instagram Story safe zones. The top and bottom of Stories are overlaid with UI elements. Placing text or key visuals in those areas means they will be partially hidden.
- Using one image for all formats. A square post, a story, and a profile picture all have very different aspect ratios. Resize and crop separately for each format to get the best results.
