Instagram Image Sizes: Posts, Stories, Reels and Profile Photos

Instagram image formats and placements at a glance

Instagram uses different image shapes for feed posts, carousels, Stories, Reels and profile photos. Starting with the intended placement helps avoid unwanted cropping, blurry uploads and artwork that becomes difficult to read on a phone.

These figures are useful production sizes. Not every dimension is a strict platform requirement, and Instagram can change previews, available layouts and supported presentation over time.

Square, portrait and landscape Instagram feed-post dimensions

Square Instagram posts: 1080 × 1080px

A square 1:1 image remains useful for product photographs, promotional graphics, announcements and simple artwork shared across several social networks. Keep small text readable when the image appears on a mobile screen.

Portrait Instagram posts: 1080 × 1350px or 1080 × 1440px

The established 4:5 portrait size is 1080 × 1350px. Instagram also supports taller 3:4 photographs, making 1080 × 1440px a useful option for images captured in the native shape of many smartphone cameras.

Both formats are valid creative choices. The 3:4 version provides 90 additional vertical pixels at the same 1080px width, while 4:5 remains a familiar size for reusable social media artwork.

Landscape Instagram posts: 1080 × 566px

A horizontal image measuring approximately 1080 × 566px uses a 1.91:1 aspect ratio. It suits landscapes, wide scenes and horizontal graphics, although it occupies less vertical space in a mobile feed than a portrait post.

Instagram carousel image dimensions and slide consistency

Instagram carousels can use square, 4:5 portrait or 3:4 portrait images. The important production decision is to keep every slide consistent instead of mixing different dimensions within one sequence.

• Use 1080 × 1080px for a square carousel.
• Use 1080 × 1350px for a 4:5 portrait carousel.
• Use 1080 × 1440px for a taller 3:4 portrait carousel.
• Keep the same width, height, typography scale and focal positioning across every slide.
• Check the first slide carefully because the chosen presentation can affect how the remaining images appear.

For connected multi-slide designs, position text and visual elements safely within each individual image. Do not assume that separate slides will align perfectly on every device or within every preview.

Instagram Stories dimensions and text-safe areas

The practical Instagram Story size is 1080 × 1920px using a vertical 9:16 aspect ratio. This fills a typical mobile screen without requiring a square or horizontal image to be awkwardly enlarged.

However, the whole canvas is not equally safe for important information. Profile details, navigation controls, captions, stickers, reply fields and interactive elements can cover the upper or lower portions of the design.

Instagram Reel covers, thumbnails and display considerations

A vertical 1080 × 1920px source provides a practical 9:16 canvas for full-screen Reel artwork. It gives you room to prepare a clear cover image while considering how the same artwork may be cropped in other views.

Instagram's Reel guidance separately identifies 420 × 654px as the recommended cover photo size. This cover-specific recommendation is different from the full-screen 1080 × 1920px production canvas and should not be confused with a universal requirement for every Reel image.

• Keep the main title, face or product in the central area.
• Check how the cover appears in the profile grid and the main feed.
• Avoid placing critical text behind captions, interface buttons or account details.
• Use fewer words and larger typography for small mobile previews.
• Inspect the selected cover before publishing rather than relying on the full-screen view alone.

Meta's Reels advertising guidance also recommends vertical 9:16 creative and keeping important messages inside the applicable safe zone. Advertising placement guidance is useful context, but it should not be described as a universal requirement for every organic post.

Instagram profile photo dimensions

Prepare your profile image as a clean 1080 × 1080px square source. This is a practical high-quality design recommendation, not a claim that Instagram requires every profile photo to be exactly that size.

Instagram displays profile photos inside a circular frame. Corners of the square artwork are therefore less useful, and small lettering around the edges can become difficult to see.

Instagram profile-grid cropping and preview differences

The image visitors see in your profile grid may not match the full post. Instagram has moved beyond its original square-only presentation, and modern profile previews can display taller rectangular crops.

Stories, Reels, portrait feed images and carousel covers can all be shown differently depending on where they appear. A 9:16 cover may therefore lose content near its outer edges when presented as a grid tile or feed preview.

• Place faces, product details and essential wording in the central composition.
• Avoid treating the profile grid as a permanently fixed square or rectangle.
• Inspect both the full post and its profile-preview appearance.
• Allow extra breathing room around important brand elements.

Display behaviour can change as Instagram updates its interface. The safest approach is to check the current in-app crop rather than depending on an older grid template.

Instagram aspect ratios explained

An aspect ratio describes the proportional relationship between image width and height. Choosing the correct ratio is often more important than simply uploading a larger image.

A 9:16 Story is taller than both 4:5 and 3:4 feed artwork. Uploading a full Story design as a regular feed post can therefore produce unwanted cropping unless you prepare a separate feed version.

The Social Media Image Resizer includes practical Instagram square, 4:5 portrait, landscape and Story presets. For a custom 1080 × 1440px artwork, use the image resizing tool and select the required dimensions.

Instagram image compression, JPG versus PNG and quality preservation

Instagram processes and recompresses uploaded media. Starting with an appropriately sized, clean file gives you more control than uploading a large image and hoping the platform preserves every detail.

• Prepare artwork at the intended dimensions, usually 1080px wide.
• Avoid repeatedly downloading, editing and recompressing the same JPG.
• Start with a high-quality original instead of enlarging a small screenshot.
• Keep text clear, correctly spaced and large enough for mobile viewing.
• Review the finished file before uploading, especially around faces, gradients and fine lettering.
• Check Instagram's high-quality upload setting where it is available.

Common Instagram cropping, readability and upload mistakes

• Using a Story image as an ordinary feed post: a 9:16 design can be cropped when placed in a shorter feed format.
• Mixing carousel dimensions: inconsistent slide sizes can produce unwanted crops and uneven layouts.
• Ignoring 3:4 portrait support: some smartphone photographs no longer need to be cropped down to 4:5.
• Confusing a Reel cover with a full-screen canvas: the cover recommendation and the vertical source dimensions are different.
• Placing text against the edges: interface overlays, captions and profile-grid crops can hide important information.
• Using a low-resolution source: enlarging a small image rarely produces a sharp final result.
• Overcompressing photographs: aggressive compression can introduce visible blocks, colour banding and softer facial details.
• Uploading an unnecessarily large PNG: photographic artwork often works better as an optimised JPG.
• Assuming every device shows the same crop: check actual mobile previews before publishing.
• Forgetting the circular profile photo: logos and faces positioned too close to the corners can be cut off.
