## In short

- The recommended size for an Instagram post in 2026 is 1080 × 1350 pixels, in 4:5 portrait format.
- Stories and Reels are made at 1080 × 1920 pixels (9:16), leaving the top and bottom of the screen clear, since the interface covers them.
- An Instagram carousel takes up to 20 photos or videos, and by default every slide takes on the format of the first one.
- Since January 2025, the profile grid shows each post at 3:4: a 4:5 post loses about 34 pixels on the left and right, a square post loses 135 on each side.
- The profile picture is uploaded at 320 × 320 pixels and shown in a circle, so the corners disappear.

The right **Instagram post size** in 2026 is **1080 × 1350 pixels**, in 4:5 portrait format. Stories and Reels are made at **1080 × 1920 pixels** (9:16). A carousel takes up to 20 slides, and your profile grid shows each post at 3:4, which trims the edges slightly.

The **aspect ratio** is the relationship between width and height: 4:5 means 4 units wide for every 5 units tall.

| Format | Ratio | Recommended dimensions | Use |
|---|---|---|---|
| Portrait post | 4:5 | 1080 × 1350 px | The default feed format |
| Square post | 1:1 | 1080 × 1080 px | Logo, product, the classic feed |
| Landscape post | 1.91:1 | 1080 × 566 px | Panorama, a wide shot of the dining room |
| Vertical photo | 3:4 | 1080 × 1440 px | Photo taken on a phone, posted from the app |
| Carousel | 4:5 recommended | 1080 × 1350 px per slide | Up to 20 photos or videos |
| Story | 9:16 | 1080 × 1920 px | Today's announcement, visible for 24 hours |
| Reel | 9:16 | 1080 × 1920 px | Vertical video |
| Reel cover | 9:16 | 1080 × 1920 px | Thumbnail: the grid only shows the central 1080 × 1440 px |
| Profile picture | 1:1 | 320 × 320 px | Logo, shown in a circle |
| Grid thumbnail | 3:4 | Automatic | Preview of each post on your profile |

## What is the ideal Instagram post size?

According to [Instagram's official Help Center](https://help.instagram.com/1631821640426723), a photo keeps its original resolution if it is between 320 and 1080 pixels wide and its aspect ratio falls between 1.91:1 and 4:5, which means a height of 566 to 1350 pixels at 1080 wide. An image wider than 1080 pixels is scaled down. The simple rule: **work at 1080 pixels wide**, then choose the height.

### 4:5 portrait: 1080 × 1350 px

This is the **Instagram post format** to go for: posters, prices, quotes, photos of a dish. It takes up more height than a square and is accepted everywhere.

### 1:1 square: 1080 × 1080 px

The original format still works, but it takes up 20% less height than a 4:5, and the profile grid crops a quarter of its width.

### 1.91:1 landscape: 1080 × 566 px

It looks small in the feed, and the grid only keeps the center. Save it for photos that only make sense wide.

### What about 3:4?

Since late May 2025, Instagram has displayed photos at 3:4 without cropping them, both as single posts and in carousels ([Social Media Today](https://www.socialmediatoday.com/news/instagram-adds-support-phone-camera-aspect-ratio-images/749205/)). It is the native format of most phone cameras: 1080 × 1440 pixels. However, [Meta's publishing API](https://developers.facebook.com/docs/instagram-platform/instagram-graph-api/reference/ig-user/media), which scheduling tools rely on, only accepts ratios between 4:5 and 1.91:1.

## Why is 4:5 the best choice for the feed?

1. **More room on screen.** 1350 pixels tall versus 1080 for a square: 25% more height for the same width.
2. **Almost nothing cropped in the grid.** The switch to 3:4 only removes about 34 pixels on the left and right.
3. **Accepted everywhere.** The app, ads ([Meta's ads guide](https://www.facebook.com/business/ads-guide/update/image/instagram-feed) recommends 4:5 for the feed) and the publishing API. A 3:4 visual falls outside these limits as soon as you go through ads or a scheduling tool.
4. **One template.** Single posts and carousels share the same format, so the feed stays consistent.

## What are the dimensions of an Instagram story and a Reel?

**Instagram story dimensions** and Reel dimensions are the same: **1080 × 1920 pixels**, in 9:16, the whole phone screen. Instagram raised the maximum Reel length to 3 minutes in January 2025 ([Engadget](https://www.engadget.com/social-media/instagram-swoops-in-with-3-minute-reels-and-rectangular-profile-grids-as-the-tiktok-ban-gets-real-201316339.html)). [Meta's documentation](https://developers.facebook.com/docs/instagram-platform/instagram-graph-api/reference/ig-user/media) for publishing through the API accepts Reels up to 15 minutes long and video stories up to 60 seconds.

### Where does the interface cover a story or a Reel?

A **safe zone** is the part of the image that no Instagram button or text covers. Everything that matters (headline, price, date, logo) has to fit inside it.

- **Story**: the top shows the progress bar, your profile picture and your name; the bottom shows the reply field and the buttons. Leave about 250 pixels clear at the top and bottom ([Buffer](https://buffer.com/resources/instagram-image-size/)), which leaves a safe zone of about 1080 × 1420 pixels in the center.
- **Reel**: the bottom is busier (caption, account name, audio title), with a column of buttons on the right. For its 9:16 ad formats, Meta asks you to keep at least 14% clear at the top, 35% at the bottom and 6% on the sides ([Meta's ads guide](https://www.facebook.com/business/ads-guide/update/video/instagram-reels)). On 1080 × 1920, that comes to about 270 pixels at the top, 670 at the bottom and 65 on each side.

> Meta's margins are the most cautious: stick to them and your text stays readable in stories and Reels alike.

## What size is an Instagram carousel?

The **Instagram carousel size** is the same as a post: **1080 × 1350 pixels per slide**, at 4:5. A carousel can hold **up to 20 photos or videos** ([Instagram Help Center](https://help.instagram.com/269314186824048/)). The limit went from 10 to 20 in August 2024 ([Social Media Today](https://www.socialmediatoday.com/news/instagram-expands-carousels-to-20-frames/723792/)).

Three rules to know:

- **One ratio for every slide.** By default, Instagram applies the format of the first slide to the whole carousel: if it is square, the following slides are cropped to square. An option keeps each photo's original format ([Lindsey Gamble](https://www.lindseygamble.com/blog/instagram-rolls-out-the-ability-to-share-photos-in-their-original-aspect-ratio-to-more-users)), but for a carousel with text, keep every slide in the same format.
- **Scheduling tools have their own limits.** [Meta's documentation](https://developers.facebook.com/docs/instagram-platform/content-publishing) still lists a maximum of 10 items per carousel published through the API, cropped to match the first image.
- **The first slide does all the work.** It is the one that shows up in the feed and in the grid. It carries the hook and signals that there is more to come.

## What size is an Instagram Reel cover?

A Reel cover is made at **1080 × 1920 pixels** ([Buffer](https://buffer.com/resources/instagram-image-size/)). But the profile grid only shows its center, at 3:4, an area of 1080 × 1440 pixels ([Hootsuite](https://blog.hootsuite.com/social-media-image-sizes-guide/)). The top and bottom 240 pixels disappear. Place the title in the central band, between 240 and 1680 pixels from the top.

## What size is an Instagram profile picture?

Upload a square image of at least **320 × 320 pixels**: Instagram shows it in a circle about 110 pixels across on mobile ([Hootsuite](https://blog.hootsuite.com/social-media-image-sizes-guide/)). The corners are lost. Center your logo with some margin around it, and forget the tagline, which is unreadable at that size.

## What does the 3:4 profile grid crop?

Since January 2025, the profile grid has shown rectangles instead of squares ([Engadget](https://www.engadget.com/social-media/instagram-swoops-in-with-3-minute-reels-and-rectangular-profile-grids-as-the-tiktok-ban-gets-real-201316339.html)), in **3:4 format** ([Buffer](https://buffer.com/resources/instagram-image-size/)). In the feed, each post keeps its format. On your profile, its thumbnail is cropped to the center:

| Published format | Visible in the grid | What disappears |
|---|---|---|
| 4:5 (1080 × 1350) | about 1012 × 1350 px | about 34 px on the left and right |
| 1:1 (1080 × 1080) | 810 × 1080 px | 135 px on each side, a quarter of the width |
| 9:16 (1080 × 1920) | 1080 × 1440 px | 240 px at the top and bottom |
| 1.91:1 (1080 × 566) | about 425 × 566 px | more than half the width |
| 3:4 (1080 × 1440) | everything | nothing |

Instagram lets you adjust the preview after posting, from the post's “…” menu: crop, zoom in or add borders ([Planoly](https://www.planoly.com/blog/guide-to-instagrams-new-vertical-grid)). Better not to need it.

### How do you keep important text in the safe zone?

- **On a 4:5 post**, keep headlines, prices and the logo at least 60 pixels from the left and right edges: 34 are cropped, the rest gives breathing room.
- **On a square post**, everything that matters fits in the central 810 pixels.
- **On a Reel cover**, center the title vertically.
- **Write big and short**: with three columns, each thumbnail is a third of the screen's width.
- **Check your profile** right after posting.

Fixed margins are part of good [Instagram brand guidelines](https://muffino.ai/en/blog/instagram-brand-guidelines/). That is Muffino's approach: its posts are composed natively at 4:5 and its stories at 9:16, with the text inside the area that stays visible in the grid. The Chez B post at the top of this article is an example: headline, logo and labels all stay well away from the edges.

## How do you export Instagram visuals without losing sharpness?

- **Width: 1080 pixels.** It is Instagram's reference width. Meta accepts images up to 1440 pixels wide through the API and recommends 1440 × 1800 for feed ads, but 1080 is enough for a post.
- **PNG for text, JPEG for photos.** PNG keeps letters and flat colors sharp; high-quality JPEG is lighter for a photo. Both are accepted ([Meta's ads guide](https://www.facebook.com/business/ads-guide/update/image/instagram-feed)). Instagram reprocesses every file on upload, so start from a clean image.
- **Colors in sRGB.** It is the color space Meta's API requires. Another profile, such as Adobe RGB, can shift the colors.
- **A reasonable file size.** Meta caps images at 30 MB for ads and 8 MB through the API. A well-exported 1080 × 1350 pixel visual stays far below that.
- **Video in MP4.** For a Reel or a video story: MP4 at 1080 × 1920, H.264 compression, a constant frame rate and AAC audio, as [Meta's ads guide](https://www.facebook.com/business/ads-guide/update/video/instagram-reels) recommends.

## Posts in the right formats, no calculator needed

Learning these numbers is useful once; applying them to every post takes time. Muffino reads your website (logo, colors, fonts, photos) and builds a design system that looks like your brand, delivered as 4:5 posts, carousels, 9:16 stories and Reels exported as MP4.

## Frequently asked questions

### What is the ideal Instagram post size in 2026?

1080 × 1350 pixels, in 4:5 portrait format. It is the tallest format accepted by the app, by ads and by scheduling tools alike, and the profile grid crops almost nothing from it.

### What size is an Instagram story?

1080 × 1920 pixels, in 9:16, which is the whole phone screen. Leave about 250 pixels clear at the top and bottom: your name and the reply field appear there.

### How many photos can you put in an Instagram carousel?

Up to 20 photos or videos in the app, since August 2024. If you publish with a scheduling tool, check its limit: Meta's API documentation still says 10 items.

### Why are my posts cropped on my Instagram profile?

Since January 2025, the profile grid shows 3:4 thumbnails. A square or landscape post is cropped to the center; you can adjust the preview from the post's “…” menu.

### Should you post at 3:4 instead of 4:5?

Since May 2025, 3:4 displays without cropping for photos posted from the app. But the publishing API and in-feed ad formats stop at 4:5, which remains the safest choice for a visual with text.

### PNG or JPEG for Instagram?

PNG for visuals with text, a logo or flat color, because the edges stay sharp. High-quality JPEG for photos. Either way, export in sRGB at 1080 pixels wide.
