Instagram Vertical Dimensions: Exact Pixel Sizes for Every Placement (2026)

Instagram vertical dimensions are 1080 × 1350px at a 4:5 aspect ratio for standard feed posts, and 1080 × 1920px at 9:16 for both Stories and Reels.

Upload the wrong size and Instagram will silently crop your content no prompt, no preview, no warning.

Full-Format Instagram Vertical Dimensions Reference: Every Placement at a Glance

Before getting into the detail for each placement, here is every vertical size in one place.

Most creators look up a single number and move on. What catches people off guard is that the same vertical image renders differently in the feed than it does on the profile grid a distinction that silently breaks a lot of carefully designed posts.

Feed Post Sizing: What Instagram Actually Accepts

Get the dimensions wrong here and Instagram crops your post silently no alert, no preview.

The Right Dimensions and Aspect Ratio for the Feed

The correct instagram image size for a vertical feed post is 1080 × 1350 pixels at a 4:5 aspect ratio. This is not a guideline it is the platform's hard ceiling.

Instagram only accepts aspect ratios between 1.91:1 and 4:5 inside the feed. Anything taller than 4:5 is automatically cropped before the post goes live.

If you have created a 9:16 portrait and uploaded it as a regular feed post, Instagram did not ask for permission it simply cut it.

Most content teams standardize on 1080 × 1350px as their default vertical format because it maximizes visible screen space without triggering that automatic crop.

How Instagram Handles Incorrect Aspect Ratios

Instagram's auto-crop behavior works outward from the center. It does not detect your subject, read your text, or locate faces. It crops to fit.

A logo placed near a corner, a headline near the top edge, or a person slightly off-center can disappear entirely. The only reliable fix is to size correctly before uploading, every single time.

Upload Resolution: What Matters and What Doesn't

• Below 320px wide — Instagram scales the image up, softening the result
• Above 1080px wide — Instagram scales it down automatically
• Exactly 1080px wide — sharpest output, no scaling applied

Upload at 1080px. There is no quality benefit to uploading at a larger size.

Profile Grid Cropping: Why Your Feed Post Looks Different There

Your feed shows the full 4:5 image (1080 × 1350px). The profile grid, however, crops that same image to 3:4 (1012 × 1350px) a slightly narrower frame. The crop comes from the sides, not from the top or bottom.

In practical terms: if you have placed a brand name, a face, or a key design element near the left or right edge, the grid will clip it. Center your important content.

Always check the grid preview before publishing, particularly for a series of posts intended to look cohesive.

Instagram Story Dimensions and Safe Zone Rules

Stories fill the entire phone screen but only if you use the right size and respect the interface boundaries.

The Right Size for Instagram Stories

Stories run at 1080 × 1920 pixels a 9:16 aspect ratio for both photos and videos. This is full-screen vertical, the format most strongly associated with mobile-first content.

Video Stories appear in 15-second segments. You can record up to 60 seconds, which the platform divides into four segments automatically.

Where the Interface Eats Your Content

The full canvas is 1080 × 1920px, but the usable area where your content remains visible without interference is 1080 × 1610px.

The top and bottom bands are occupied by Instagram's own interface the profile handle and name at the top, the reply bar at the bottom. Anything placed in those zones gets buried beneath the UI.

Keep all text, logos, calls to action, and faces within the 1080 × 1610px safe zone. It sounds like a minor restriction. In practice, ignoring it is one of the most common design mistakes in Stories creation.

Reels Size Requirements and Grid Thumbnail Cropping

Reels and the feed share the same 9:16 frame but the profile grid crops them differently, and most creators don't catch it until it's too late.

The Right Size for Instagram Reels

Reels display at 1080 × 1920 pixels in the feed the same 9:16 ratio as Stories.

For the upload:

• File formats: MP4 or MOV
• Maximum file size: 4GB
• Duration: 15 seconds to 15 minutes

As reported by TechCrunch, time spent on Instagram grew by more than 24% after the platform launched Reels a direct outcome of the vertical short-form format driving stronger engagement than static posts.

This growth mirrors the broader shift in how digital content creators are shaping platform

behaviour and pushing 9:16 as its dominant vertical standard.

Both the main feed and the Reels tab display the full 9:16 frame. The profile grid, however, is a different story.

How Reels Grid Thumbnails Get Cropped

The grid thumbnail for a Reel crops to 3:4 (1080 × 1440px) — not 9:16, and not 1:1. This surprises many creators who expect either the full vertical frame or a square crop.

When selecting a cover photo for your Reel, upload at 1080 × 1920px or choose a frame directly from the video. Either way, center the most important visual.

The grid crops from the sides and bottom, so anything near the outer edges may not appear in the thumbnail at all.

Carousel Post Sizing: The First-Slide Rule You Can't Ignore

Carousels use the same vertical dimensions as standard feed posts: 1080 × 1350px at 4:5. You can include up to 20 images or videos per carousel post.

What most creators overlook is the first-image rule. Instagram locks the aspect ratio for the entire carousel based on the first slide. If your opening image is vertical at 4:5, every subsequent slide regardless of its original size gets cropped to 4:5.

This becomes a real problem when mixing orientations. A landscape photo inserted into a vertical carousel gets heavily cropped. The platform offers no warning, and the result almost never looks intentional.

The clean solution: keep all slides in the same orientation. If you are going vertical, go vertical throughout.

Vertical Ad Sizes: How Specs Differ from Organic Posts

Ads follow the same basic vertical proportions as organic posts, but come with stricter safe zone requirements because UI overlays in ads take up more screen real estate than they do in regular content.

Vertical Feed Ads

Size: 1080 × 1350px at 4:5. Minimum accepted width is 500px, minimum height 400px. Supported aspect ratios mirror the feed: 1.91:1 to 4:5.

Stories Ads

Size: 1440 × 2560px at 9:16. Leave the top ~250px and bottom ~340px completely free of text, logos, and key visuals. Those zones are occupied by the profile handle above and the CTA button below.

Reels Ads

Size: 1440 × 2560px at 9:16. The safe zone here is more demanding top 14%, bottom 35%, and 6% on each side should remain clear.

The larger bottom margin exists because Reels ads carry a heavier overlay: CTA button, caption, and audio label all stack at the bottom.

Many brands design Reels ads at the organic Reel size (1080 × 1920px) and then find that text gets covered. The ad spec differs from the organic spec for a reason the overlay footprint is simply larger.

Why Vertical Formats Win on Mobile

Vertical content occupies more screen space. A 4:5 post demands more scroll time to pass than a 1:1 square, which translates to more time spent looking at your content. That is not a marketing claim it is geometry.

According to data from Statista, mobile devices accounted for over 62% of global website traffic as of mid-2025. Most of those users hold their phones upright. Vertical content fills that natural viewing frame. Landscape content shrinks to fit, leaving empty bars above and below.

Getting the aspect ratio for Instagram right can seem like a technical detail. But wrong dimensions affect how your content is cropped, how your grid reads, and whether your ad text survives the platform's overlays.

It is less about aesthetics and more about whether your intended message actually reaches the

viewer intact.

Conclusion

For vertical Instagram content: use 1080 × 1350px (4:5) for feed posts, 1080 × 1920px (9:16) for Stories and Reels, and 1440 × 2560px for ads. Always check your profile grid separately it crops differently from the feed.

Frequently Asked Questions

What is the correct vertical image size for an Instagram feed post?

1080 × 1350 pixels at a 4:5 aspect ratio. This is the maximum vertical size Instagram allows in the feed. Anything taller is auto-cropped to fit within the supported ratio range.

Why does my vertical post look different on my profile grid?

The profile grid applies a 3:4 ratio (1012 × 1350px), which is slightly narrower than the feed's 4:5. Keep key content centered to avoid edge cropping on the grid.

What is the difference between 4:5 and 9:16 on Instagram?

4:5 is for standard feed posts. 9:16 is for Stories and Reels. Instagram does not allow 9:16 in the regular feed uploading one results in an automatic crop to 4:5.

Can I use vertical images in an Instagram carousel?

Yes, at 1080 × 1350px (4:5). All slides after the first are auto-cropped to match the first slide's ratio. Use a consistent vertical orientation throughout to avoid unintended cropping.

What file formats work for vertical Instagram content?

For images: JPG, PNG, and BMP. For video (Reels and Stories): MP4 or MOV.
