Instagram Image Sizes in 2026: Posts, Stories, Reels & Carousels

Instagram gives creators more flexibility with image dimensions than it once did, but the added choice also makes sizing more important. Feed photos can now use the taller 3:4 aspect ratio, Stories still require a full-screen 9:16 canvas, and the profile grid can display your creative differently from the original post.

Getting those dimensions right matters because static imagery still plays a meaningful role in social performance.

In our State of Social Media Marketing Report, image-based posts accounted for 25.3% of the content formats associated with the highest engagement, showing that well-designed static creative still earns attention alongside short-form video.

On Instagram, though, good creative can lose some of that impact when the dimensions are wrong. An image may be cropped differently on your profile, lose important text near the edges, or require additional resizing after upload.

For most portrait Feed images in 2026, 1080 × 1440 pixels at 3:4 is our preferred starting point. Instagram added native 3:4 photo support back in 2025 for both single-image posts and carousels, making it possible to publish images in the same taller proportion used by many smartphone cameras.

This guide covers the recommended dimensions for Feed posts, Stories, carousels, Reel covers, profile pictures, and the profile grid, along with the crop and export checks that help your images look the way you intended.

Instagram Image Sizes at a Glance

Instagram uses different image dimensions depending on where your creative appears. For Feed posts, 1080 pixels wide remains the most practical working width, while the height changes with the aspect ratio you choose.

Here are the Instagram image sizes we recommend using in 2026:

Currently, Instagram supports vertical Feed images at both 4:5 and 3:4, with 1080 × 1350 and 1080 × 1440 as the corresponding working dimensions. The current profile grid also uses a taller 3:4 preview, which makes the newer 1080 × 1440 canvas especially useful when profile presentation matters.

If You Remember One Instagram Feed Image Size

Use:

• 1080 × 1440 px
• 3:4

We recommend this as the strongest all-around starting point for a new portrait Instagram Feed image in 2026.

Instagram introduced native 3:4 photo support in May 2025, allowing photos captured at that ratio to appear without being forced into the older square or 4:5 formats. The update applies to both individual photos and carousel posts.

The ratio also aligns naturally with Instagram's current taller profile-grid previews, reducing the amount of composition planning needed between the Feed post and profile view.

That does not make 4:5 obsolete. A 1080 × 1350 portrait remains fully supported and is still a useful choice for brands with existing 4:5 templates or compositions that work better at that height.

Think of 3:4 as the new default option, rather than a replacement for every other Instagram image ratio.

What Is the Best Instagram Image Size in 2026?

The best Instagram image size depends on whether the image is destined for the Feed, Stories, a carousel, a Reel cover, or your profile.

For a standard portrait Feed image, our recommendation is:

• 1080 × 1440 pixels at 3:4

It gives you more vertical space than a square image, is natively supported by Instagram, and corresponds with the taller shape now used in profile-grid previews.

For other placements, use:

• Feed portrait: 1080 × 1440 / 3:4
• Classic portrait: 1080 × 1350 / 4:5
• Square: 1080 × 1080 / 1:1
• Landscape: 1080 × 566 / 1.91:1
• Story: 1080 × 1920 / 9:16
• Reel cover working master: 1080 × 1920 / 9:16

The choice matters because each ratio creates a different composition.

A 3:4 or 4:5 image gives a product, person, or piece of editorial creative more vertical space in the Feed. A square works well when the design is intentionally centered. Landscape is useful when the width of the scene carries information that would be lost in a portrait crop.

Stories and Reel covers require a different approach altogether because their working canvas is much taller.

The practical rule is:

Choose the Instagram placement first, then design for its aspect ratio. Avoid designing one image and relying on Instagram to crop it for every placement.

Instagram Image Size vs. Aspect Ratio

These terms are closely related but describe different things.

Image size refers to the dimensions of the file in pixels. For example:

• 1080 × 1440 px

Aspect ratio describes the shape of that image:

• 3:4

Two files can have the same aspect ratio while using different pixel dimensions. A 540 × 720 image and a 1080 × 1440 image are both 3:4, but the second contains more pixels.

For Instagram production, the ratio determines how the content is framed, while the pixel dimensions determine how much image information you provide within that frame.

A useful working system is therefore:

Choose the ratio first then build at the recommended dimensions. Check the crop next, and then export for that placement.

For Feed photos, that means starting with one of Instagram's supported shapes rather than asking the platform to correct an incompatible image after upload.

Next, we'll break down each Feed format individually, starting with the newer 3:4 Instagram post size, followed by 4:5 portrait, square, and landscape images.

Instagram Feed Post Sizes

Instagram Feed images no longer revolve around a single square format. You can publish square, landscape, and two portrait ratios, including the newer 3:4 format that Instagram added natively in 2025.

For most new portrait creative, we recommend starting with 1080 × 1440 pixels at 3:4. The other formats remain useful when the composition calls for a different shape.

The right choice depends on the image itself. A portrait of a person or product can use the extra vertical space available in 3:4, while forcing a wide group photo into the same frame may remove information the image needs.

3:4 Instagram Post Size

• Recommended size: 1080 × 1440 pixels
  
• Aspect ratio: 3:4

The biggest Instagram image-size change to account for in 2026 is native 3:4 photo support.

Instagram introduced the format in May 2025, allowing 3:4 photos to appear in the Feed as they were captured rather than being forced into one of the platform's older ratios. The change applies to both single-photo posts and carousels.

For marketers, that makes 1080 × 1440 a particularly useful working canvas. It gives you more vertical room than 4:5 while also matching the shape of Instagram's current 3:4 profile grid. Current Instagram sizing guidance now includes 1080 × 1440 alongside the older 1080 × 1350 portrait format.

Use 3:4 when you are:

• Creating new portrait-first Feed assets
• Publishing smartphone photography already captured at 3:4
• Designing editorial graphics that benefit from additional height
• Planning content with the profile grid in mind

The added space is especially useful for layouts that need to accommodate a subject and supporting copy without compressing everything toward the center.

4:5 Instagram Post Size

• Recommended size: 1080 × 1350 pixels
  
• Aspect ratio: 4:5

The arrival of 3:4 does not make 4:5 an outdated Instagram format.

A 1080 × 1350 image remains fully supported and is particularly useful for brands that already have established social templates, campaign assets, or design systems built around 4:5. Current sizing guidance continues to list both portrait ratios.

Visually, 4:5 is slightly wider relative to its height than 3:4. That can suit product layouts, quote cards, promotional graphics, and compositions that need a little more horizontal breathing room.

The main difference to consider is the profile grid. Instagram's current grid uses a 3:4 preview, so a 4:5 post can be framed slightly differently when someone visits your profile.

We will show exactly what that means in the crop guide below.

Square Instagram Post Size

• Recommended size: 1080 × 1080 pixels
  
• Aspect ratio: 1:1

Square posts remain supported on Instagram, and there is no need to abandon them when the creative is genuinely designed around a square composition.

A 1:1 canvas still works well for:

• Centered product photography
• Logos and brand announcements
• Symmetrical graphics
• Quote cards
• Creative that also needs to work across other square placements

What has changed is the context around the image.

Instagram's profile grid no longer displays every post inside the old square thumbnail system. Since the grid now uses taller previews, a square post can be shown with a tighter horizontal crop when viewed on your profile.

That makes central composition more important than it was when both the Feed asset and grid thumbnail were square.

Landscape Instagram Post Size

• Recommended size: 1080 × 566 pixels
  
• Aspect ratio: 1.91:1

Landscape is the widest standard Feed format and makes sense when the width of the image is part of the story.

Examples include:

• Group photography
• Landscapes
• Interiors
• Event scenes
• Wide product arrangements
• Before-and-after compositions designed horizontally

The tradeoff is screen space. A landscape image occupies less vertical room in a mobile Feed than either 3:4 or 4:5, and its composition differs significantly from Instagram's tall profile-grid previews.

Avoid converting an image to portrait purely to use more Feed space if doing so removes the subject or context that makes the photograph work.

For landscape creative, keeping the most important element relatively close to the center also makes the image easier to adapt when Instagram displays it elsewhere.

Instagram Profile Grid Size and Crop Guide

An Instagram image has two related but separate presentations:

• The image you publish to the Feed
• The thumbnail people see when they visit your profile.

Instagram moved its profile grid away from square thumbnails in January 2025, replacing them with taller, vertically aligned previews. The change was intended to better reflect the vertical photos and videos people increasingly publish on the platform.

Current sizing guidance treats the grid as a 3:4 format, making 1080 × 1440 pixels a useful design reference when checking how important elements will appear on your profile.

That does not mean every Feed image now needs to be uploaded at 3:4.

It means your Feed canvas and your profile-grid presentation can have different shapes.

3:4 Posts in the Instagram Profile Grid

A 1080 × 1440 / 3:4 Feed image naturally matches the current grid shape.

That makes 3:4 the easiest format when you want the Feed composition and profile presentation to remain closely aligned.

A headline positioned comfortably within the canvas, for example, requires less adjustment between the two views than it would on a square or wider image.

This is one of the reasons we recommend 3:4 as the default starting point for new portrait creative.

How a 4:5 Instagram Post Is Cropped in the Grid

A 4:5 post measures:

• 1080 × 1350 pixels

If we calculate a centered 3:4 preview using that full 1350-pixel height, the visible width is approximately:

• 1013 pixels

That leaves roughly 34 pixels per side outside the central 3:4 area.

These measurements are an IMH calculated production guide, not crop margins published by Instagram.

The practical impact is relatively small, but it matters when text, logos, faces, or product details sit very close to the left or right edge.

A 4:5 Feed design therefore does not need to be rebuilt simply because the grid is 3:4. It needs enough horizontal breathing room for the critical content.

How a Square Instagram Post Is Cropped in the Grid

The difference is more noticeable with a square post.

A standard square image is:

• 1080 × 1080 pixels

A centered 3:4 region using the full 1080-pixel height is:

• 810 pixels wide

That leaves approximately 135 pixels per side outside the central 3:4 region.

Again, these are IMH calculated crop guides, rather than official Instagram safe-zone measurements.

For square creative, keep critical information comfortably toward the middle instead of placing headlines, logos, or products directly against the left and right edges.

What About Landscape Images?

Landscape images present a bigger composition challenge because their full Feed canvas is significantly wider than the profile-grid preview.

Trying to reduce that difference to one universal pixel margin is less useful than treating the grid as a separate presentation.

For landscape posts:

• Keep the primary subject close to the center.
• Avoid placing essential copy at the far edges.
• Check the actual profile thumbnail before publishing.

Instagram also introduced thumbnail editing for profile-grid posts in 2026, giving users more control over how existing images and clips are framed on their profiles. That provides another opportunity to correct an awkward grid presentation after choosing the Feed composition.

The feature is useful, but we would still design with the grid in mind from the beginning rather than relying on thumbnail adjustment to rescue a difficult layout.

What Should Stay Inside the Instagram Grid Safe Area?

Anything that changes the meaning of the image should remain comfortably inside the central composition.

That usually includes:

• Faces and primary subjects
• Products
• Headlines
• Brand logos
• Prices and promotional offers
• CTA copy

Decorative backgrounds, textures, scenery, and other non-essential elements can extend farther toward the edges.

A useful design test is:

If this element disappeared from the profile thumbnail, would someone still understand the post?

If the answer is no, move it inward.

Instagram Profile Grid Crop Reference

*The 4:5 and square figures are IMH calculations for a centered 3:4 design reference, not official Instagram crop specifications. Instagram's thumbnail controls can also let you adjust the visible framing.

Instagram Story Image Size

Instagram Stories use a much taller canvas than Feed posts, so images designed for the Feed usually need to be reformatted before they are reused here.

For Stories, use:

• 1080 × 1920 pixels
• 9:16

This fills the vertical Story viewer and gives you the most control over where subjects, text, branding, and interactive elements appear.

A square or Feed portrait image can still be placed inside a Story, but it will not naturally fill the 9:16 canvas. Instagram may leave additional space around it, or you will need to enlarge and crop the original image.

For planned Story creative, it is better to start with the vertical canvas rather than adapting a finished Feed graphic afterward.

Instagram Story Safe Zones

Correct dimensions give you the full Story canvas. They do not guarantee that every part of that canvas will remain equally visible.

Instagram places interface elements around Story content, including account information and progress indicators toward the top and reply or interaction controls toward the bottom. Stickers, links, polls, and other elements can occupy additional space depending on the Story.

That makes the outer portions of the canvas less suitable for essential information.

Keep these elements comfortably inside the central area:

• Headlines and supporting copy
• Faces and primary subjects
• Products
• Logos
• Prices and offers
• Promo codes
• Important CTA text

Background photography, colors, patterns, and decorative elements can extend closer to the edges.

For production, roughly 250 pixels at the top and bottom can be treated as a practical caution area, rather than a hard Instagram specification. Interface layouts can vary, so the final Story preview should always be the deciding check.

A good test is simple: if Instagram covered the element, would the Story still communicate what you need it to? If the answer is no, move it inward.

For more guidance on structuring the content itself, see our guide to Instagram Stories.

Instagram Carousel Image Size

Instagram carousels give you more room to build a sequence, but the individual images still need a deliberate canvas.

For a new portrait-first carousel in 2026, our recommended starting point is:

• 1080 × 1440 pixels
• 3:4

Instagram added native 3:4 photo support in 2025 for both individual image posts and carousels, so images captured or designed at that ratio can now appear without being forced into the older 4:5 format.

You can also build carousels using the other supported Feed dimensions:

For most branded or educational carousels, portrait formats are the stronger starting point because they give typography, products, photography, and supporting information more vertical room on a mobile screen.

How Many Images Can an Instagram Carousel Have?

Instagram allows up to 20 photos or videos in a single carousel post, doubling the platform's previous 10-item limit.

That does not mean every carousel needs 20 slides. The extra capacity is useful when the story genuinely requires it, such as:

• Step-by-step guides
• Event or campaign recaps
• Product collections
• Before-and-after sequences
• Data or educational carousels

For a marketing carousel, the number of slides should still be determined by the story rather than the technical maximum.

One further consideration is your publishing workflow. Native Instagram functionality can move ahead of third-party scheduling platforms and API-based publishing, so check the tool you use if you are planning a carousel with more than 10 items.

Should Every Instagram Carousel Image Be the Same Size?

For a deliberately designed carousel, we recommend using one consistent working ratio across the entire sequence.

Instagram's support for different photo shapes gives you flexibility when uploading casual photography, but consistency makes a designed carousel much easier to control.

Using the same canvas across the sequence helps maintain:

• Typography: Headlines and supporting copy stay in predictable positions.
• Spacing: Margins and visual hierarchy remain consistent from one slide to the next.
• Swipe continuity: Visual elements can intentionally continue across cards.
• Templates: Future carousels become easier to create from the same system.
• Crop control: You know how every card should behave in the Feed and profile grid.

For example, if the first slide is designed at 1080 × 1440 / 3:4, create the remaining designed slides at the same dimensions unless the content gives you a specific reason to do otherwise.

3:4 vs. 4:5 for Instagram Carousels

Both portrait formats work well. The choice comes down to how your creative system is built.

Use 3:4 / 1080 × 1440 when:

• You are creating a new carousel template
• You want to take advantage of the taller native photo format
• Profile-grid presentation matters
• Your source photography is already 3:4

Use 4:5 / 1080 × 1350 when:

• Your brand already has established 4:5 templates
• Existing campaign assets use 4:5
• The slightly wider composition suits the layout better

There is little value in rebuilding a well-designed 4:5 system simply because 3:4 is newer. The important change is that marketers now have both portrait options available, rather than being restricted to 4:5.

For more ideas on structuring the sequence itself, see our guide to using Instagram carousels.

Instagram Reel Cover Size

A Reel cover is an image asset rather than part of the video itself, so it deserves its own sizing workflow. The cover needs to work when the Reel is opened full-screen and when Instagram presents a tighter preview on your profile grid.

For production, we recommend starting with:

• 1080 × 1920 pixels
• 9:16

Instagram’s published Reel cover recommendation is 420 × 654 pixels, but a higher-resolution 1080 × 1920 working master gives designers more room to build the cover alongside the Reel itself and manage crops across different placements.

The important distinction is that the full Reel cover and the profile-grid preview do not use the same shape.

A cover can look perfectly balanced when viewed with the Reel, yet lose part of a headline, face, logo, or product when Instagram presents it inside the taller profile grid.

How Reel Covers Appear on the Profile Grid

Instagram’s current grid uses a 3:4 preview, while our Reel-cover working canvas is 9:16.

That means the profile version shows a shorter vertical portion of the full cover.

The practical implication is simple. Avoid placing essential cover content near the extreme top or bottom of the 9:16 canvas.

Keep these elements comfortably within the central composition:

• Reel headline
• Face or primary subject
• Product
• Brand logo
• Series or episode marker
• Other information someone needs to identify the Reel

Decorative photography, backgrounds, textures, and color can extend across the full cover.

This is especially important for brands using a repeatable Reel-cover system. A consistent central layout makes the profile grid easier to scan and reduces the chance of titles shifting unpredictably from one Reel to the next.

For the video dimensions themselves, see our full guide to Instagram video sizes.

Instagram Profile Picture Size

Instagram profile pictures are much simpler than Feed images, but the circular display means composition still matters.

Use:

• 320 × 320 pixels
• 1:1

The source image should be square, while Instagram displays it inside a circular frame.

That circular crop affects the outer corners of the file, so logos, faces, initials, or other identifying elements should sit comfortably toward the center.

For a personal or creator account, leave enough space around the face so the circular crop does not feel overly tight.

For a brand account, avoid designing a logo that touches all four sides of the square canvas. Give the mark enough breathing room to remain legible when it is reduced to a much smaller profile icon.

Simple rule: Design the file as a square, but judge the composition through a circle.

This matters particularly for logos containing small text. A wordmark that looks sharp at 320 × 320 can become difficult to recognize once it is reduced inside Instagram’s interface, so simpler marks generally work better.

Why Is Instagram Cropping My Image?

Instagram cropping usually happens because the image you uploaded and the placement displaying it use different aspect ratios.

That distinction is easy to miss because the same image can appear correctly in the Feed and still look different in your profile grid, Stories, or another Instagram surface.

The fastest way to diagnose the issue is to identify where the crop occurs.

Your Image Uses a Different Ratio From the Placement

A 3:4 Feed post and a 9:16 Story are both portrait formats, but their shapes are very different.

Taking a finished 1080 × 1440 Feed graphic and stretching it to 1080 × 1920 will distort the image. Enlarging it until the Story canvas is filled can cut content from the sides.

Instead, create the new 9:16 canvas and reframe the existing creative inside it.

That might mean repositioning:

• The subject
• Headline
• Logo
• Product
• CTA
• Supporting graphics

The same principle applies when adapting square, landscape, or 4:5 assets.

Your Feed Image and Profile Grid Use Different Shapes

This is one of the most common sources of confusion in 2026.

An image can use a perfectly valid Instagram Feed ratio and still appear differently on your profile because the grid uses a 3:4 preview.

That is why we recommend performing a separate profile-grid check for:

• 4:5 posts
• Square posts
• Landscape posts
• Reel covers

The Feed composition should still be designed for the original format. The grid check simply helps you protect the elements that matter most.

You Reused a Feed Image in Stories

A Feed image at 3:4, 4:5, or 1:1 will not naturally fill a 9:16 Story canvas.

You can keep the complete image visible by placing it within a designed vertical Story layout, or crop and reframe it when the source image gives you enough room.

For branded creative, the first option can work especially well. The unused vertical space can hold:

• A headline
• Background color or photography
• Supporting copy
• Stickers
• A link
• CTA messaging

This usually looks more intentional than forcing the Feed image to fill the Story frame.

Your Reel Cover Works Full-Screen but Breaks on the Grid

A Reel cover built at 1080 × 1920 / 9:16 has more vertical space than the 3:4 profile preview.

Text placed at the extreme top or bottom therefore carries more crop risk.

The fix is to compose critical information inside the central grid-safe region while allowing decorative imagery to use the full cover.

Instagram Is Cropping an Unsupported Feed Ratio

For standard Feed photos, use one of the supported working formats covered earlier:

• 3:4
• 4:5
• 1:1
• 1.91:1

Uploading creative outside the supported Feed range gives Instagram less room to preserve the original framing.

Where possible, crop the image yourself before upload. You will have much more control over which part of the photograph or design is removed.

How to Resize an Image for Instagram

Resizing an Instagram image is less about changing the pixel count and more about protecting the composition. A square post, 3:4 Feed image, and 9:16 Story all frame the same creative differently.

The simplest workflow is:

1. Choose the destination.
   Start with the format you are publishing to: Feed, Story, carousel, Reel cover, or profile picture.
2. Set the correct canvas.
   For example, use 1080 × 1440 / 3:4 for our recommended Feed portrait or 1080 × 1920 / 9:16 for Stories.
3. Reframe instead of stretching.
   Move or crop the image so the subject fits the new canvas naturally. Stretching distorts people, products, logos, and other visual elements.
4. Check the final crop.
   For Feed posts and Reel covers, preview how important elements will appear on the 3:4 profile grid. For Stories, check that text and products remain clear of interface-heavy areas.
5. Export for the final placement.
   Create the Instagram-ready version from your highest-quality source rather than repeatedly resizing an already compressed image.

Best Instagram Image Format and Export Settings

Once the canvas is correct, the export should preserve as much of the original quality as possible without creating an unnecessarily complicated workflow.

JPG vs. PNG for Instagram

JPG is the safest general choice for photography and images with lots of colors, gradients, or detail.

PNG can work better for designed graphics, illustrations, and assets containing sharp text or flat colors, provided the publishing method supports it.

There is no useful universal rule such as “always export at 80% or 90% quality.” Different editing tools calculate compression differently. Instead, use a high-quality export that retains detail without repeatedly recompressing the same image.

Why Does Instagram Reduce Image Quality?

Instagram processes images after upload, so some difference between your original file and the published version can occur.

Quality problems tend to become more noticeable when the source has already been weakened before Instagram receives it. Common causes include:

• Starting with a low-resolution image
• Enlarging a small image to fit a larger canvas
• Downloading and re-uploading previously compressed social images
• Using screenshots instead of original files
• Repeatedly exporting the same JPG
• Applying excessive compression during export

The safest workflow is straightforward:

Start with the best original → resize for the correct Instagram canvas → export once → preview before publishing.

Uploading a larger file cannot restore detail that was lost earlier in the process. Correct dimensions and a clean source usually matter more than chasing the biggest possible export.

Keep Your Instagram Images Sharp in 2026

Instagram image sizing is easier once you separate the file you upload from the way Instagram displays it across the app.

For most new portrait Feed images, 1080 × 1440 pixels at 3:4 is the strongest starting point. Stories use 1080 × 1920 / 9:16, while square, 4:5, and landscape posts remain useful when the creative calls for them.

The dimensions are only the first step. Profile-grid crops, Story interface areas, Reel-cover previews, and carousel consistency all affect how the final creative appears.

Start with the correct canvas, keep important content away from vulnerable edges, export from a clean source, and preview the final placement before publishing.
