Instagram Aspect Ratios and Sizes for 2026: Every Format, the 3:4 Grid and How to Avoid Cropping

The best Instagram aspect ratios in 2026 are 4:5 (1080 x 1350 pixels) for feed photos and carousels and 9:16 (1080 x 1920) for Reels and Stories. Instagram keeps feed photos between 1.91:1 and 3:4, crops anything outside that range, and shows posts on your profile grid as 3:4 rectangles, so keep key content centred.

Aspect ratios sound like a design detail, but they decide how much of the screen your post occupies, whether your headline gets clipped on the profile grid, and whether Instagram quietly crops the edge of your product shot. The rules also changed in 2025, when Instagram replaced its square profile grid with taller rectangles. This guide covers every Instagram format with the exact pixel sizes, what Instagram's own Help Centre says, where the safe zones are, how to export from the tools you already use, how the same image should change for other networks, and how to avoid the cropping mistakes that make good content look sloppy.

Key findings: Instagram aspect ratios in 2026

• 1,080 pixels is the maximum width. Instagram's Help Centre says it keeps "the best resolution possible (up to a width of 1,080 pixels)" and scales wider images down.
• Feed photos are kept between 1.91:1 and 3:4. The same page says photos between 320 and 1,080 pixels wide keep their native resolution in that range, which at 1,080 pixels wide means a height from 566 to 1,440 pixels.
• Anything outside the range is cropped. In Instagram's words: "If the aspect ratio of your photo isn't supported, it will be cropped to fit a supported ratio."
• The profile grid is now 3:4. Instagram switched from square to rectangular grid tiles in January 2025, as Engadget reported. Hootsuite's October 2026 guide lists grid tiles at 1012 x 1350 for photos and 1080 x 1440 for Reels.
• Reels and Stories are 9:16. Instagram's recommendation tips for creators ask for "high-resolution 9:16 vertical video" with no borders.
• Carousel slides follow the first slide. Meta's Content Publishing documentation says carousel images "are all cropped based on the first image in the carousel".
• Stories have a safe area. Hootsuite recommends keeping important Story content within 1080 x 1610 pixels of the 1080 x 1920 frame.

What's changed for Instagram sizes in 2026

Most Instagram size guides were written for a square grid and a 4:5 maximum. Four changes since then affect how you should design.

The grid went from square to 3:4

For more than a decade, Instagram showed your posts on your profile as squares, so designers kept key content inside the middle 1:1 of every image. In January 2025 Instagram changed the grid to taller rectangles. Engadget quoted Adam Mosseri explaining that most uploads are vertical and that cropping them into squares was "just a bummer to overly crop them", and calling the switch "a transitional pain". Older posts designed for the square grid now show more of their top and bottom and less of their sides. New posts should be designed for a 3:4 crop.

Instagram now documents a 3:4 maximum for photos

For years the tallest supported feed photo was 4:5 (1080 x 1350). Instagram's current Help Centre page describes a supported range from 1.91:1 to 3:4, which allows images up to 1080 x 1440. Many third-party guides, including Hootsuite's, still list 4:5 as the tallest feed ratio, and the in-app cropper and scheduling tools differ in what they accept. The safe choice is still 4:5, which works everywhere. If you post directly in the app and want your feed image to match the grid exactly, 3:4 is now an option.

Carousels went to 20 slides

Instagram raised the carousel limit from 10 to 20 photos and videos in August 2024, as Metricool reported during the rollout. The aspect ratio rule did not change: every slide is cropped to the shape you choose for the first. Publishing through Meta's API is still limited to 10 items.

Reels got longer, with a 3-minute recommendation limit

Reels can now run from 3 seconds to 3 minutes for normal recommendation, according to Instagram's 2026 Reels guide. Instagram's Help Centre article on recording Reels describes videos up to 20 minutes, but adds that "Reels over 3 minutes won't be recommended to new audiences." Length is not an aspect ratio, but it shapes how you plan vertical video.

Instagram sizes by format: the complete reference

Here is every Instagram format with the size we recommend, the ratio, and where the number comes from. Keep this table open while you design.

Sizes from Instagram's resolution help page and Hootsuite's 2026 size guide. For the matching specs on other networks, see our guide to social media image sizes.

Feed photos

A 4:5 portrait image takes up more of the phone screen than a square or landscape one, which is why it has been the default for brands for years. At 1080 x 1350 it sits comfortably inside Instagram's documented range. A landscape image at 1.91:1 occupies roughly half the vertical space of a 4:5 image, so it is easy to scroll past. Use landscape only when the content truly needs width, such as a panoramic view or a wide product line-up.

Carousels

Carousels use the same feed ratios, with one important rule: the first slide decides the shape for all of them. If you build slide one at 4:5 and slide five at 1:1, slide five gets stretched into a 4:5 frame by cropping. Export every slide from one template at one size. For more on structure, see our Instagram carousel best practices. Hootsuite's carousel guide lists video slides at 3 to 60 seconds in MP4 or MOV, up to 4GB.

Reels

Reels are 9:16 vertical video at 1080 x 1920. Instagram's recommendation guidance asks for high resolution, no borders and text that does not cover most of the screen. On your profile grid, Reels are shown as 3:4 tiles, so the top and bottom of the frame are hidden there. Choose a cover frame, or design a custom cover, with its title in the central area. In Explore, Meta's Reels system card predicts how likely you are to "click one of the tall, rectangular reels in Explore to view it in full screen", so the cropped preview tile has to earn that click on its own. Keep the subject central.

Stories

Stories are also 9:16 at 1080 x 1920. The difference from Reels is the interface on top: your profile picture and name sit at the top, and the reply bar at the bottom. Keep text, faces and stickers inside the 1080 x 1610 safe area that Hootsuite recommends. Photos in Stories display for seven seconds, according to Sprout Social's 2026 Stories playbook, so a text-heavy Story image needs to be readable in that time.

Profile photo

Upload a 320 x 320 square with the subject centred. Instagram crops it to a circle, so logos with text near the corners lose the text. Test it at a small size before you change it, because the profile photo appears tiny next to Stories and comments.

Your profile photo also appears in places you might not think about: the Stories tray, comment threads, DMs, search results and the header of every post. In most of them it is shown at well under 100 pixels across. A detailed photo of your whole team becomes an unreadable smudge at that size. A clear face for personal brands, or a simple, high-contrast logo mark for businesses, reads everywhere. When you change it, keep the new version consistent with your other networks so people recognise you when they move between them.

Does aspect ratio affect Instagram performance?

Instagram does not publish a ranking signal for aspect ratio, and no large study we could verify isolates ratio from everything else. What the data does show is that format matters, and format and shape are closely linked.

Figures from Buffer's State of Social Media Engagement 2026 and Socialinsider's benchmarks of 35 million posts from 447,613 pages. Buffer also found Reels reached 2.25 times as many accounts as single images, so the 9:16 format earns attention through reach even when its engagement rate is lower.

Why taller usually wins in the feed

The mechanism is screen space. On a phone held upright, a 4:5 image fills far more of the screen than a 1.91:1 landscape image, which means more time in view and a better chance of stopping the scroll. Meta's Instagram Feed system card includes predictions about how much time you will spend on a post, and a post that occupies more of the screen simply has more chance to hold attention. That is an inference rather than a documented rule, so treat it as a reason to default to portrait, not a guarantee of reach.

Why the shape still has to suit the content

A cramped 4:5 crop of a wide group photo can perform worse than the same photo shown honestly in landscape, because people cannot see what is going on. Use portrait by default and break the rule when the content needs it. When you have several wide images, a carousel at 4:5 usually solves the problem better than a single landscape post.

The 3:4 profile grid: how to design for it

The rectangular grid is the change that most affects how brands design. Your grid is your shop window: profile visitors decide whether to follow based on how it looks, and every tile is now a 3:4 crop of whatever you posted.

How each post shape is cropped on the grid

Design rules for the 3:4 grid

• Keep headlines and faces inside the central area of a 4:5 image, with a margin of around 35 pixels on each side.
• Avoid edge-to-edge text on square images. The grid trims the sides more heavily.
• Never rely on landscape images for anything that must read on the grid.
• For Reels, place the cover title in the middle third of the frame.
• Plan your grid in rows of three. Our free Instagram feed planner and grid maker preview how a set of posts will look together.

Old posts after the switch

Posts you made for the square grid now show a different crop. Usually that looks fine. If a pinned post or a key carousel now has a clipped headline, you can adjust the thumbnail crop when you edit the post in the app, or replace it with a new version designed for 3:4.

Safe zones for every format

A safe zone is the part of a frame where nothing in Instagram's interface will cover your content. See our glossary entry on safe zones for the concept, and use our Instagram safe zone checker to overlay them on your design.

Reels deserve extra care because the overlay is busy. Your username and caption sit along the bottom, and the like, comment, share and audio buttons run down the right side. Text placed in the bottom fifth or along the right edge will be covered for most viewers. Instagram's guidance that text should not cover most of the screen is a ranking consideration as well as a design one.

Export settings by tool

The same size can be exported well or badly. These settings keep Instagram's compression from muddying your images.

Why uploading larger files does not help

According to Instagram's Help Centre, images wider than 1,080 pixels are reduced to 1,080 and images narrower than 320 are enlarged. A 4,000-pixel export gives Instagram more work to do and no extra quality on screen. Export at exactly 1,080 pixels wide. If file size is an issue, our image compressor shrinks files without visible loss.

File formats for scheduled posts

If you schedule through a tool that publishes via Meta's API, note that Meta's documentation says "JPEG is the only image format supported" for image publishing. Most scheduling tools convert PNG uploads for you, but if text-heavy graphics look soft after publishing, export them as high-quality JPEGs yourself and check the result.

Watermarks and borders

Two things do not fix a ratio problem. Adding white borders to make a landscape image fit 4:5 shrinks the content and, for Reels, runs against Instagram's request for "no borders". Exporting a Reel from another app with its watermark is worse: Instagram Ranking Explained says watermarked Reels are made less visible. Instagram's April 2026 originality update also notes that adding a border or watermark does not make reposted content original.

Video specs beyond the ratio

For video, the aspect ratio is only one of several settings that decide how your Reel looks once Instagram has processed it.

Lengths come from Instagram's Reels guide, Instagram's Stories guide and Hootsuite's carousel guide. Instagram's Help Centre article on recording and sharing reels notes that you can record up to 20 minutes, but that Reels over 3 minutes will not be recommended to new audiences. The Stories guide adds that longer Story videos are split automatically into back-to-back 60-second clips.

Shooting for several crops at once

Most phones shoot video at 9:16 when held upright, which is ideal for Reels and Stories. If you also need a 4:5 version for a carousel or a 16:9 version for YouTube, frame the action in the centre with space above and below. A 9:16 frame can be cropped to 4:5 by trimming the top and bottom, and to 3:4 for the grid in the same way, as long as faces and text sit in the middle.

Covers and Highlights covers

Reel covers are 9:16 images that show as 3:4 tiles on your grid. Highlights covers are different: Instagram's Stories guide describes them as "round covers under your profile bio". Design Highlights covers as simple centred icons or short words on a 1080 x 1920 canvas, with the mark in the middle so the circle crop keeps it.

Instagram sizes by content type and industry

The right ratio also depends on what you post. A text-heavy B2B graphic and a fashion photo have different needs.

Product photography (ecommerce, food, beauty)

Shoot at 4:5 or 3:4 with space around the product. A product cropped tight to the frame edge will lose its edges on the grid. Leave at least 10% padding on each side. For food, overhead shots work well in 4:5; for fashion, a full-length 3:4 shot fits the grid exactly.

Text graphics and educational content (B2B, coaches, SaaS)

Use 4:5 with generous side margins and large type. If you plan to reuse the same graphic on LinkedIn, consider 1:1, which works on both networks, or design at 4:5 for Instagram and export a separate 1:1 version. Our Instagram image resizer and social media image resizer make the extra versions quickly.

Real estate and travel

Landscape photos are the default in these industries, and they look small on Instagram. Either crop to 4:5 around the strongest part of the frame, or turn one wide shot into a seamless carousel with our carousel splitter, which cuts a panorama into 4:5 slides that swipe as one image.

Events and photo dumps

Mix portrait shots in a carousel at 4:5. If most of your event photos are landscape, choose 4:5 for the first slide and crop the rest to match, rather than letting Instagram do it inconsistently.

Video-first creators

Film at 9:16 for Reels and Stories. If you also post the same video to YouTube in landscape, shoot wide with the subject centred so you can crop to 9:16 without losing the action.

Local businesses

Menus, price lists and opening hours work best at 4:5 with very large type and a short list. If it would need zooming, split it across carousel slides.

Readability and accessibility at Instagram sizes

Getting the ratio right is half the job. The other half is making sure people can read and understand the post at the size it is actually shown.

Minimum text size

A 1080-pixel-wide image is shown at roughly a third of that width on most phones. Text that is 20 pixels tall in your design file becomes tiny on screen. As a rule of thumb, keep body text at least about 28 to 32 pixels tall on a 1080 x 1350 canvas and headlines at 60 pixels or more. Check contrast too: our colour contrast checker tells you whether your text and background pass accessibility guidelines.

Alt text

Instagram lets you add alt text to each image, including from the computer upload flow described in its Help Centre. For graphics that contain text, the alt text should repeat the text. For photos, describe what matters in one sentence. See our glossary entry on alt text for examples.

Designing for teams and clients

Agencies and in-house teams should store templates for every format and every client in one shared place, with the safe areas marked as locked guide layers. Most sizing mistakes happen when someone new builds a post from scratch. With templates, a freelancer or a new hire produces correctly sized posts on day one.

Instagram vs other networks: one image, several sizes

If you publish the same content to several networks, the ratio is the main thing that changes. Here is how a single Instagram image should be adapted.

Our network-specific guides cover the details: Facebook aspect ratios, Pinterest aspect ratios and YouTube aspect ratios.

Instagram sizes by account type and workflow

Who is posting, and from where, changes which sizing problems you are likely to hit.

Creators posting from a phone

Creators who shoot and post on the same phone rarely have ratio problems with Reels and Stories, because the camera is already 9:16. The problems come with feed photos, where the phone's default 3:4 photo is now within Instagram's documented range but some editing apps export at odd sizes. Check the export setting in your editing app once, set it to 1080 pixels wide, and leave it there.

Businesses posting from a computer

Teams that design on a computer are more likely to export at the wrong size or in the wrong format, because design tools default to large canvases. Instagram's Help Centre describes a computer upload flow in which you choose Create, then Post, then "Select from computer", and can trim video, pick a cover and add alt text before sharing. That flow will crop anything outside the supported range just like the app does, so the template rules above apply in full. Our guide to posting to Instagram from a desktop walks through the whole process.

Agencies managing several brands

Agencies face the same rules multiplied by every client, with each client's brand guidelines layered on top. The most reliable approach is a template library per client, a naming convention that includes the network and ratio in each file name (for example, client_product_ig_4x5.jpg), and a review step that checks every scheduled post on a phone preview before approval.

Teams scheduling ahead

When posts are scheduled days or weeks ahead, nobody is watching the moment they go live, so a cropped image can sit on your profile for hours. Check sizes at the point of scheduling, not at the point of publishing. That is the strongest argument for building templates: once every file comes out of a correctly sized template, scheduling ahead carries no sizing risk at all. For the scheduling side, see our guide on how to schedule Instagram posts.

Worked example: one photo shoot, six networks

Consider a hypothetical furniture brand that photographs a new armchair. The photographer shoots the chair in a styled room, leaving space on every side, in both portrait and landscape. From that shoot, the social lead exports:

• Instagram feed: a 4:5 carousel at 1080 x 1350 with the chair centred, a detail shot, the chair in context and a final slide with dimensions.
• Instagram Stories: a 1080 x 1920 version of the hero shot with the price and a link sticker placed in the safe area.
• Facebook: the same 4:5 images as a photo album.
• LinkedIn: a single 1:1 image for the company page, which suits a feed where LinkedIn says images earn twice the comment rate of text-only posts.
• Pinterest: a 2:3 Pin at 1000 x 1500, the size Pinterest recommends, noting that Pins taller than 2:3 "might get cut off in people's feeds".
• X: a single 16:9 landscape crop of the room.

All six versions are attached to one post on the team's calendar, each with its own caption, and scheduled for the same launch morning. Nothing gets cropped by a network, because nothing was sent in the wrong shape.

A step-by-step method for never getting cropped again

1. Pick one feed ratio and stick to it. For most brands that is 4:5. Consistency also makes your grid look deliberate.
2. Build templates. Create a 1080 x 1350 feed template, a 1080 x 1920 Story template with the safe area marked, and a 1080 x 1920 Reel cover template with the 3:4 grid area marked.
3. Mark the grid crop on feed templates. Add a guide for the central 3:4 area so you never put text outside it.
4. Shoot with the crop in mind. Leave space around subjects so a crop never cuts through a face or product.
5. Export at exactly 1,080 pixels wide. Use JPEG for photos, sRGB colour, high quality.
6. Check carousel slides are identical in size. One different slide breaks the whole carousel.
7. Preview on a phone. Look at the image in the feed and as a grid tile before you post.
8. Make network versions in the same session. Export your 1:1 and 2:3 variants alongside the Instagram one so cross-posting does not mean redesigning later.
9. Schedule from one place. Attach each network's version to the same post on your calendar so the right file goes to the right network.
10. Audit your grid monthly. Check pinned posts and recent tiles for clipped text, and fix the thumbnail crop when needed.

How Postprism handles sizes

Postprism is a social media scheduler that publishes to six networks from one content calendar. When you schedule a post for several networks, the editor keeps a separate version for each, so a 2:3 version can go to Pinterest while a 1:1 image goes to LinkedIn and a shorter caption goes to X. The media requirements page in our developer docs lists the formats each network accepts.

Common Instagram sizing mistakes and how to fix them

1. Uploading landscape photos to the feed. They take little space and lose most of their width on the grid. Fix: crop to 4:5 or turn them into a carousel.
2. Designing for the old square grid. Square-safe designs now lose their sides. Fix: design for a central 3:4 area.
3. Mixed slide sizes in a carousel. Every slide is cropped to the first. Fix: export all slides from one template.
4. Text in the Story danger zones. The profile bar and reply box cover it. Fix: keep text inside 1080 x 1610.
5. Reel captions at the very bottom. They sit under the username and caption overlay. Fix: place on-screen captions in the middle third.
6. Exporting at 4,000 pixels. Instagram resizes to 1,080 anyway. Fix: export at 1,080 wide.
7. Adding white borders to fit a ratio. The content shrinks and Reels with borders are discouraged. Fix: recompose or crop properly.
8. Uploading watermarked video. Watermarked Reels are made less visible. Fix: export clean files.
9. Logos with text in the profile photo corners. The circle crop removes them. Fix: use a centred mark.
10. Reusing an Instagram image on Pinterest unchanged. It looks short among 2:3 Pins. Fix: export a 1000 x 1500 version.
11. Not checking on a phone. A design that reads on a monitor can be illegible on a phone. Fix: preview every post on mobile.
12. Forgetting the Reel cover. A random frame becomes your grid tile. Fix: choose or design a cover with the title centred.

Frequently Asked Questions

What is the best aspect ratio for Instagram posts?

4:5 portrait at 1080 x 1350 pixels. It takes the most vertical space of the widely supported feed ratios and works in every tool. Instagram's Help Centre now documents support up to 3:4 (1080 x 1440), which matches the profile grid, but 4:5 remains the safe default.

What size is the Instagram profile grid now?

The grid uses 3:4 rectangles since January 2025. Hootsuite lists the display size as 1012 x 1350 pixels for photos and 1080 x 1440 for Reels. A 4:5 image loses a thin strip from each side on the grid, and a square image loses more.

What happens if my image is the wrong ratio?

Instagram crops it. Its Help Centre says that if the aspect ratio of your photo is not supported, it "will be cropped to fit a supported ratio". Supported feed ratios run from 1.91:1 landscape to 3:4 portrait.

What size should Reels and Stories be?

1080 x 1920 pixels at 9:16. Keep Story content within the central 1080 x 1610 area, and keep the key part of a Reel inside the middle 1080 x 1440 so it shows on the grid and is not covered by the caption and buttons.

Can carousel slides have different sizes?

No. Every slide is cropped to match the shape of the first one. Choose one ratio, usually 4:5, and export every slide at the same size.

What resolution should I upload?

1,080 pixels wide. Instagram keeps native resolution between 320 and 1,080 pixels wide and scales larger images down, so bigger files add nothing on screen.

What size is the Instagram profile picture?

Upload a 320 x 320 pixel square. Instagram shows it as a small circle, so keep the subject or logo centred with space around the edges.
