Instagram does not use one universal image shape. Feed photos, Stories, and Reels place the same source inside different frames, and interface controls can cover part of a vertical image. The practical solution is to prepare separate crops rather than force one composition into every placement.
For a reliable starting workflow, use 1080 pixels as the working width for Instagram images. Square posts use 1080 × 1080, portrait posts commonly use 1080 × 1350, and full-screen Stories and Reels use a 1080 × 1920 canvas. Instagram’s current photo help also describes a broader accepted feed-photo range, so these are useful production presets—not a claim that every other upload is rejected.
| Placement | Working size | Aspect ratio | Composition |
|---|---|---|---|
| Square feed post | 1080 × 1080 | 1:1 | Balanced center crop. |
| Portrait feed post | 1080 × 1350 | 4:5 | More vertical feed space without a full-screen crop. |
| Story | 1080 × 1920 | 9:16 | Full-screen vertical with room for interface overlays. |
| Reel canvas or cover artwork | 1080 × 1920 | 9:16 | Keep the main subject away from overlay-heavy edges. |
Use the Instagram Image Resizer to generate these versions from one image. The Focus Point gives the automatic crop a subject to protect, and each preset can still be adjusted independently. Processing stays in your browser.
Instagram feed photo sizes
Portrait: 1080 × 1350 (4:5)
A 4:5 portrait post occupies more vertical space in the feed than a square image while remaining a conventional feed composition. It works well for people, products, before-and-after layouts, and vertical graphics. Place important text and faces away from the extreme edges so minor display variations do not make the design feel cramped.
Instagram’s photo-resolution guidance has evolved and currently describes support beyond the older 4:5-only portrait boundary. That does not make 1080 × 1350 obsolete: it remains a useful, predictable preset for cross-tool workflows. If you deliberately use a taller feed photo, preview it in the current Instagram application before building a campaign around that crop.
Square: 1080 × 1080 (1:1)
Square is the simplest reusable feed shape. It gives equal weight to horizontal and vertical content and remains useful for product grids, announcements, and designs that may move between platforms. Its limitation is obvious: a landscape or portrait source loses more of its original frame than it would in a matching orientation.
Landscape feed images
Instagram can accept landscape photos, but the visible feed footprint is smaller. Do not add permanent bars merely to manufacture a square file. If the original photograph depends on its wide composition, preserve it and verify the current preview. If feed presence matters more than the full width, create a separate portrait crop.
Instagram Story dimensions
A Story canvas is 1080 × 1920, which is 9:16: width first, height second. This matches a phone held vertically. A landscape image can either fill the canvas by cropping its sides or fit inside it with empty/blurred space. Neither choice is universally correct.
- Use Fill when a full-screen result matters and the subject can survive cropping.
- Use Fit when the entire image, screenshot, menu, or graphic must remain visible.
- Use a Focus Point before applying Fill to keep a face or product inside the crop.
- Review the overlay because usernames, reply controls, stickers, and other interface elements vary.
The Instagram Story Resizer includes an optional interface-safe overlay. Treat it as guidance rather than a permanent platform specification: Instagram can change controls, and the visible interface varies by device and account features.
Instagram Reel dimensions and cover composition
Reels are vertical-first, so 1080 × 1920 (9:16) is the practical full-screen canvas. The same pixel dimensions as a Story do not mean the same crop should be used. Reel controls, captions, and discovery surfaces create different visual pressure. Keep faces, logos, and essential words near the central area and inspect the artwork at phone size.
Instagram’s Reels help describes a supported aspect-ratio range and a minimum resolution rather than promising that every surface shows the entire frame identically. A cover may also appear in places with a different preview crop. Avoid putting essential information only in the top or bottom edge.
Use the Instagram Reel Image Resizer separately from the Story preset. Even though both exports are 9:16, independent crop state lets you position the subject for each use.
One source image, four separate crops
Aspect ratios determine how much of the source survives:
- A wide photo loses substantial left and right content in 9:16.
- A tall portrait loses top and bottom content in 1:1.
- A centered subject usually transfers more easily than a subject close to an edge.
- Text baked into an image cannot reflow when the crop changes.
Start by marking the visual subject. Generate automatic crops, then inspect each one. Adjust Story and Reel independently instead of copying a 9:16 crop by default. Copy a crop to presets with the same ratio only when the composition truly works for all of them.
Fit versus Fill for Instagram
| Mode | What it preserves | Trade-off | Best for |
|---|---|---|---|
| Fill | The entire destination frame | Some source content is cropped | Photographs and full-bleed creative |
| Fit | The entire source image | Background space may be added | Screenshots, menus, diagrams, text graphics |
Do not stretch an image to fit. Stretching changes proportions and makes people, products, and logos look wrong. Crop or add background space instead.
File format and export quality
JPG is a sensible default for photographs. PNG is useful when you need transparency or crisp flat graphics, though it may be larger. WebP is efficient but confirm that every publishing step in your workflow accepts it. Instagram may recompress uploads, so sending an enormous file does not guarantee a better final result.
Export from the best source available and avoid repeated JPEG saves. Check small text and detailed edges after compression. Keep a high-quality master so future platform changes do not force you to work from an already compressed copy.
Common Instagram image mistakes
- Reusing one crop for feed, Story, and Reel without checking the subject.
- Writing “16:9” for a vertical 1080 × 1920 image; the correct order is 9:16.
- Placing text under Story or Reel controls.
- Stretching a landscape image into a vertical canvas.
- Using low-resolution source material and expecting resizing to recreate detail.
- Assuming safe-zone measurements can never change.
- Flattening a transparent graphic onto an unintended black background.
FAQ
What is the best size for an Instagram portrait post?
1080 × 1350 pixels at 4:5 is a dependable working preset. Instagram’s current accepted photo range may permit taller images, but 4:5 remains practical across design and scheduling workflows.
What size should an Instagram Story be?
Use a 1080 × 1920 pixel canvas at 9:16 for a full-screen vertical Story.
Are Stories and Reels the same size?
They commonly share a 1080 × 1920, 9:16 canvas. Their interface and preview contexts differ, so keep separate crops when necessary.
Should I choose Fit or Fill?
Choose Fill for edge-to-edge photos and Fit when every part of the source must remain visible. Never stretch solely to remove empty space.
Do safe zones guarantee that nothing is covered?
No. They are a visual guide. Instagram’s interface varies and can change, so verify important campaign creative in the current app.
