Start with a 1080-pixel-wide canvas for an Instagram feed post: 1080 × 1080 px for square, 1080 × 1350 px for 4:5 portrait, 1080 × 1440 px for 3:4 portrait, or 1080 × 566 px for approximately 1.91:1 landscape.
Choose the shape that fits your composition, then enter those dimensions in Canva, Photoshop, or another design tool. Sharp results depend on the source image, exported pixel dimensions, and Instagram’s processing—not on setting a document to 300 PPI.
Instagram post sizes at a glance
| Format and ratio | Canvas dimensions | Useful for |
|---|---|---|
| Square · 1:1 | 1080 × 1080 px | Balanced graphics and reusable layouts |
| Portrait · 4:5 | 1080 × 1350 px | Products, infographics, and text-led designs |
| Taller portrait · 3:4 | 1080 × 1440 px | Vertical photography with less cropping |
| Landscape · approximately 1.91:1 | 1080 × 566 px | Panoramas and wide compositions |
Instagram’s official photo-resolution guidance lists a supported photo aspect-ratio range from 1.91:1 through 3:4. The dimensions above fit within that range. Profile previews can still frame or crop a composition differently from the full feed image.
A width of 1080 pixels is a practical working standard, not a promise of compression-free output. It provides a consistent canvas across design applications, while Instagram may still process the uploaded file.
Choose by subject rather than assuming one format is always better:
- Square: useful when you want a balanced composition that is easy to adapt to other layouts.
- 4:5 portrait: offers more vertical feed space for a product, heading, and supporting details.
- 3:4 portrait: suits tall photographs, particularly when a shorter crop would remove important content.
- Landscape: preserves width for scenery, architecture, or subjects arranged horizontally.
Stories use a different presentation from feed posts. Do not treat a full-screen vertical layout as interchangeable with a feed canvas; adapt the composition rather than relying on automatic cropping.
Aspect ratio, pixel dimensions, and PPI
These settings describe different things:
- Aspect ratio is the shape: width compared with height.
- Pixel dimensions are the number of pixels across and down.
- PPI, or pixels per inch, connects those pixels to a physical print size. DPI refers to printer dots and is often used loosely in discussions of image resolution.
A 1080 × 1350 px image and a 2160 × 2700 px image both have a 4:5 aspect ratio. They share a shape, but not the same number of pixels. When reviewing an Instagram photo you have permission to save, Grabfy's Instagram Photo Downloader provides a separate workflow for downloading supported public photo posts. You can inspect the saved file's pixel dimensions to understand its actual resolution, but do not assume the downloaded copy preserves the creator's original upload quality.
To calculate the height:
Height = width × ratio’s second number ÷ ratio’s first number
For a 4:5 canvas:
1080 × 5 ÷ 4 = 1350 px
For a 3:4 canvas:
1080 × 4 ÷ 3 = 1440 px
For landscape, 1080 ÷ 1.91 is approximately 565.45. A 566-pixel height gives the commonly used near-1.91:1 canvas.
Why changing PPI does not fix blur
In Photoshop, you can observe the distinction directly:
- Open a 1080 × 1350 px image.
- Choose Image > Image Size.
- Deselect Resample.
- Change Resolution from 72 Pixels/Inch to 300 Pixels/Inch.
- Check the pixel dimensions shown in the dialog. They remain 1080 × 1350 px.
The physical print dimensions change, but no image pixels are added. The image does not gain detail simply because its resolution metadata now says 300 PPI.
Resampling changes the pixel count, but enlarging a small image does not reliably recover missing detail. A 540-pixel-wide raster image enlarged to 1080 pixels can still look soft. Inspect the actual source and export dimensions rather than relying on the PPI value.
Set up your Instagram design canvas
The same setup formula works across design tools:
- Choose the aspect ratio based on your subject and layout.
- Set the width to 1080 pixels.
- Enter the corresponding height: 1080, 1350, 1440, or 566 pixels.
- Work in RGB, rather than CMYK.
- Use sRGB for export where the application offers color-profile control.
- Check export scaling so the output matches your intended dimensions.
Canva
- Start a custom-size design.
- Choose pixels as the measurement unit.
- Enter the width and height—for example, 1080 × 1350 px.
- Arrange the content on that canvas instead of assuming a template uses your preferred ratio.
- At export, check any available size controls and inspect the resulting file’s dimensions.
If color-profile settings are not exposed, focus on using sRGB source assets and checking the exported image.
Photoshop
- Create a new document with width and height measured in pixels.
- Enter the selected dimensions.
- Choose RGB Color and an sRGB profile, such as sRGB IEC61966-2.1.
- Place your source images and inspect them at 100% view.
- Export at the intended pixel dimensions, using conversion to sRGB where available.
Keep the layered document so you can adapt the composition without repeatedly editing a compressed export.
Figma
- Create a frame with the chosen width and height, such as 1080 × 1440.
- Keep all intended artwork inside the frame.
- Export the frame at 1× for matching raster dimensions.
- Inspect the exported file; a 2× export doubles both dimensions.
Use sRGB where color-profile controls are available.
Adobe Express
- Select or create a custom-size canvas.
- Enter the target pixel dimensions.
- Reposition artwork to fit the chosen ratio.
- Check the exported dimensions rather than relying only on a preset’s name.
Affinity Photo
- Create an RGB document.
- Set the dimensions in pixels.
- Choose sRGB where profile settings are available.
- Check that the export dimensions match the canvas.
The application does not determine the correct Instagram size. Your chosen ratio and the exported pixel dimensions do. These canvas recommendations focus on static Instagram feed images. Standard video posts involve additional considerations, including video resolution and encoding. If you need to inspect a supported public video that you are authorized to save, Grabfy's Instagram Video Downloader offers a separate workflow. Check the resulting file's properties rather than assuming image export settings apply to video.
Choose JPEG or PNG
| Export type | Suitable content | Main caution |
|---|---|---|
| JPEG | Photographs and image-heavy designs | Compression can introduce artifacts |
| PNG | Flat graphics and text-led layouts | Upload processing can alter sharpness |
JPEG is generally practical for photographs because it balances visual detail and file size. PNG can suit flat colors, diagrams, sharp-edged artwork, and layouts with substantial text.
PNG also supports transparency in your design workflow, but do not depend on transparent areas becoming a particular background on Instagram. Add the intended background before export.
Neither format prevents Instagram processing. Fine text, subtle gradients, and sharp edges may change after upload. PNG is not guaranteed to look sharper than JPEG once posted.
For cleaner exports:
- Export from the editable master, not a previously compressed copy.
- Choose a quality setting that avoids visible artifacts.
- Inspect fine text and edges in the exported file.
- Use RGB and sRGB where supported.
RGB and sRGB help reduce avoidable color inconsistencies, but screens can still display the same image differently.
Protect important content from preview crops
Use a centered working area for essential text, faces, prices, logos, and calls to action. Leave breathing room between these elements and the outer edges.
This is a design precaution, not an official fixed Instagram safe-zone specification. A single margin measurement cannot guarantee identical framing in every view.
Use this crop-resilience workflow:
- Compose the full image in your chosen feed ratio.
- Keep decorative backgrounds near the edges and essential information farther inward.
- Inspect the complete feed image.
- Check the profile-grid preview separately.
- View the design at phone-sized scale to assess readability.
Profile presentation can change with app updates and differ between viewing contexts. A headline can be fully visible in the feed yet clipped in a profile preview.
When adapting a square design to portrait, reposition elements rather than simply adding empty space. When adapting portrait to square, rearrange the headline, subject, and footer instead of trimming both ends indiscriminately.
Keep every Instagram carousel slide consistent
Choose one canvas size for the set before designing. For example, use 1080 × 1350 px at 4:5 throughout a portrait carousel.
Follow this sequence:
- Set the shared dimensions. Use one master canvas or consistently sized artboards.
- Apply matching guides. Align headings, page numbers, and recurring elements.
- Inspect every slide before export. Check each page, frame, or artboard’s width, height, and aspect ratio individually.
- Export the slides. Use consistent export scale and settings.
- Inspect every exported file. Confirm its exact pixel dimensions and look for clipped artwork or unexpected background areas.
- Preview the complete carousel in Instagram. Review every slide, not just the opening image.
If you need to review an existing public carousel that you have permission to save, Grabfy's Instagram Carousel Downloader provides a separate workflow for supported carousel posts. After downloading, check each file's dimensions individually rather than assuming every slide has the same exported size.
A mismatched slide can produce an unwanted crop, border, or inconsistent composition when the set uses a common orientation. Do not assume each item will retain an independent shape.
Repair a square slide in a portrait set
Suppose nine slides are 1080 × 1350 px, but one is 1080 × 1080 px.
Adapt the square slide to the common portrait canvas using one of these approaches:
- Extend the background: retain the square artwork at its existing size and fill the additional 270 pixels of height. Centering it leaves 135 pixels above and below.
- Recompose the layout: move the heading, image, and supporting text to use the taller canvas deliberately.
- Reframe a photograph: scale it proportionally to cover the portrait canvas, then choose the crop carefully.
Do not stretch the square image vertically to make it fit. That distorts faces, products, lettering, and other shapes.
After exporting the repaired slide, inspect the complete upload preview. That is where you determine whether unwanted cropping or borders remain across the actual set.
Troubleshoot Instagram export problems
Start with the visible symptom, then compare the source, exported file, and Instagram preview.
| Symptom | Possible cause | First check |
|---|---|---|
| Blurry text | Small or enlarged raster artwork | Inspect export dimensions and source |
| Unexpected crop | Ratio mismatch or preview framing | Compare full image and preview |
| Color shift | CMYK or profile mismatch | Check RGB and sRGB conversion |
| White borders | Unfilled canvas or ratio mismatch | Inspect canvas edges and background |
| Inconsistent carousel | Different slide sizes or scaling | Compare every file’s pixel dimensions |
Blurry text
Confirm the export has the intended dimensions. Then inspect text and source artwork at 100% view, where image pixels map to display pixels.
Keep text editable until export where possible. Enlarging a screenshot of text cannot make it as clean as correctly sized live text.
Unexpected crop
Calculate the exported ratio as width ÷ height and compare it with your intended format. For example, 1080 ÷ 1350 = 0.8, matching 4:5.
If the exported file is correct, distinguish a profile-preview crop from a crop affecting the full feed image.
Color shift
Check the document’s color mode and embedded profile. If necessary, convert a copy to RGB with sRGB before export.
Conversion is different from merely assigning a profile, which can change how existing color values are interpreted.
White borders
Inspect the exported file outside Instagram. If the border is already present, check canvas bounds, background coverage, and image placement.
If it appears only during upload, check the selected crop and how the image fits the chosen presentation.
Inconsistent carousel slides
Compare every exported file’s exact width and height, then return to the source documents to correct mismatched canvases or export scales.
Correct dimensions cannot restore missing source detail or prevent all platform compression.
Check permissions for design assets
Use photos, fonts, logos, templates, and other creative assets only when their licenses or permissions cover the intended use.
Public visibility does not transfer ownership or automatically permit commercial reuse. A template’s availability also does not necessarily settle the rights to every included asset.
Keep license details, purchase records, or creator authorization with the editable project. This makes later adaptations easier to manage without losing track of usage restrictions.
Six checks before posting
- Pixel dimensions: Confirm the exported width and height match your selected format, such as 1080 × 1350 px.
- Aspect ratio: Check that the exported shape matches the intended feed presentation.
- Color mode: Use RGB, with sRGB for export where profile control is available.
- Source sharpness: Inspect important images, text, and graphics at 100% view for softness or compression artifacts.
- Carousel consistency: Check every slide’s canvas before export, compare the exported dimensions, and preview the complete set.
- Phone-sized legibility: Confirm that text, faces, prices, logos, and calls to action remain readable and sensibly framed in both the full feed image and profile preview.
