Need the short answer? For a normal Instagram feed post, 1080 × 1350 pixels (4:5) is a practical portrait canvas, while 1080 × 1080 (1:1) is the classic square format. Instagram’s current photo rules are broader than those two numbers: a feed photo can sit within a supported aspect-ratio range, so 1080 × 1440 (3:4) is also important in 2026.
This guide explains the difference between a supported size and a useful design size, so you can stop guessing before you upload.
Instagram Post Size at a Glance
| Format | Pixels | Ratio | Best use |
|---|---|---|---|
| Portrait | 1080 × 1350 | 4:5 | Most everyday feed graphics and photos |
| Tall portrait | 1080 × 1440 | 3:4 | Maximum supported portrait height |
| Square | 1080 × 1080 | 1:1 | Simple graphics, products and reusable designs |
| Landscape | 1080 × 566 | About 1.91:1 | Wide photography and horizontal visuals |
One important distinction: 1080 × 1350 is not the only size Instagram can accept. Current guidance allows a wider range of photo shapes. That matters when you are resizing an existing photo rather than creating a new template.
What Is the Best Instagram Post Size?
If you are starting a new design, 1080 × 1350 at 4:5 is a simple default. It gives you a tall feed canvas without making your design as tall as a Story or Reel.
- Use 4:5 for educational graphics, quotes, product posts and most feed designs.
- Use 1:1 when the square shape is part of the design or you need easy reuse.
- Use 3:4 when you want the tallest current feed-photo canvas.
- Use 1.91:1 when the photo really needs a wide frame.
There is no universal rule that one ratio guarantees more likes or reach. Choose the ratio that fits the content, then design for that canvas.
Instagram Post Dimensions in Pixels
Pixels describe the actual width and height of your image. Aspect ratio describes the shape.
For example, 1080 × 1350 looks like 4:5 because 1080/1350 = 0.8. A smaller image such as 800 × 1000 has the same 4:5 shape, but 1080 × 1350 gives you a larger working canvas.
For most new designs, working at 1080 pixels wide is a useful target. Instagram can resize larger files, but starting with a sensible canvas gives you more control over text, sharpness and cropping.
1080×1350 vs 1080×1440
This is where many older Instagram size guides become confusing.
1080 × 1350 = 4:5. It is a familiar portrait template used by many design tools.
1080 × 1440 = 3:4. It is taller and sits at the tall end of Instagram’s current supported photo range.
So if you see both numbers online, they are not necessarily competing answers. One is a common working format; the other represents a taller supported shape.
Instagram Post Aspect Ratios Explained
4:5 Portrait
1080 × 1350. A strong all-purpose choice for feed graphics. Keep important text away from the extreme edges so the design still feels clean when shown in different surfaces.
3:4 Tall Portrait
1080 × 1440. This gives you a taller feed image. It is useful when the extra vertical space is genuinely helpful, but it should not be confused with the 9:16 Story or Reel canvas.
1:1 Square
1080 × 1080. Square posts are easy to reuse across design systems and work well for product shots, logos and balanced layouts.
1.91:1 Landscape
1080 × 566 is the familiar working size for the widest feed-photo shape. Use it when a wide scene is more important than vertical screen space.
Why Does Instagram Crop My Post?
Cropping normally happens when your image shape does not match the supported range or when you are viewing the post in a different Instagram surface.
- Your source image is too tall or too wide.
- You designed for one ratio and uploaded another.
- Important text is too close to an edge.
- You are judging the image from a profile preview instead of the full post.
The safest workflow is simple: choose the ratio first, crop the original image yourself, then preview the final canvas before uploading.
How to Stop an Instagram Post From Getting Cropped
- Choose your final ratio before opening your editor.
- Create the canvas at the target pixel size.
- Place faces, logos and important words away from the outer edge.
- Check the complete image, not just the center.
- Export once at a good quality setting instead of repeatedly saving the same JPEG.
- Preview the result in Instagram before publishing.
Instagram Post Size for Photos vs Graphics
A photo and a graphic can use the same dimensions, but they need different design decisions. A photo can survive a little empty space. A text-heavy graphic needs breathing room around headings, icons and logos.
If you are making educational Instagram content, start with a clear headline and keep the supporting copy large enough to read on a phone. Do not fill every pixel just because the canvas allows it.
Instagram Post Size in Canva
Canva provides common Instagram presets, including square and portrait formats. If you create a custom design, enter the width and height manually instead of trusting an old template.
For a normal portrait post, use 1080 × 1350. For a square post, use 1080 × 1080. If your design specifically needs the taller 3:4 canvas, use 1080 × 1440.
Canva’s current Instagram size guide also lists 110 × 110 for profile photos and 1080 × 1920 for Stories. See the Canva Instagram sizes guide for its current presets.
What Size Should an Instagram Carousel Be?
A carousel is still built from individual images or videos, so the slide dimensions matter. A common portrait carousel canvas is 1080 × 1350. Keep the slides consistent when you want a clean swipe-through design.

Post Size and Content Ideas
The right canvas does not fix a weak idea. Once your size is ready, build the post around one clear question, lesson or action. Our Instagram post ideas guide can help when you know the format but not the topic.
Quick Troubleshooting
| Problem | Try this |
|---|---|
| Photo is cropped | Check the aspect ratio before upload. |
| Text is cut off | Move important text inward and preview the complete canvas. |
| Image looks soft | Start with a high-quality source and avoid repeated compression. |
| Post looks fine in editor but not on Instagram | Check the actual upload preview and the profile/feed view. |
