What This Tool Does
This resizer changes the width and height of your photo so it matches the dimensions Instagram expects for feed posts. Instead of letting the app crop your image automatically, you control exactly how it appears.
Use it before uploading a photo, graphic or product image to your Instagram feed. The result is an image sized correctly for the platform, ready to post without unexpected cropping.
Recommended Instagram Post Dimensions
Instagram feed posts commonly use a square format of 1080 by 1080 pixels. Portrait posts often use 1080 by 1350 pixels, while landscape posts use 1080 by 608 pixels. These sizes work well across most devices and screen resolutions.
| Post Type | Width | Height | Aspect Ratio |
|---|---|---|---|
| Square | 1080px | 1080px | 1:1 |
| Portrait | 1080px | 1350px | 4:5 |
| Landscape | 1080px | 608px | 1.91:1 |
Aspect Ratio Matters
Instagram displays your feed as a grid of thumbnails, so aspect ratio affects how your photo looks next to others. A square or 4:5 portrait format usually keeps more of your subject visible without Instagram trimming the edges.
If your original photo has a different ratio, resizing it directly may stretch or distort the image. In that case, cropping first and then resizing usually gives a cleaner result.
How to Resize an Image for Instagram
- Upload the photo you want to post.
- Select a preset Instagram post size or enter custom dimensions.
- Preview how the resized image looks.
- Adjust the width or height if needed.
- Download the resized image to your device.
Best Practices
- Keep the aspect ratio close to 1:1 or 4:5 to avoid awkward cropping on the feed.
- Start with the highest resolution version of your photo for the sharpest result.
- Preview the resized image before downloading to check composition and framing.
- Avoid enlarging small images beyond their original size, since this can reduce sharpness.
Common Mistakes
- Uploading a photo with an unusual aspect ratio and letting Instagram crop it unpredictably.
- Resizing a low-resolution image to a much larger size, which can make it look blurry.
- Ignoring the subject's position, causing important details to sit too close to the edge after resizing.
- Ignoring aspect ratio and stretching the image, which distorts faces and objects.
Conclusion
Resizing your photo to standard Instagram post dimensions helps it display correctly and look intentional in the feed. Adjust the size, preview the result, and download an image that's ready to post.
Frequently Asked Questions
What size should I resize an image for an Instagram post?
A square 1080 by 1080 pixel image works well for most feed posts. Portrait photos often use 1080 by 1350 pixels, while landscape photos use 1080 by 608 pixels.
Will resizing my image reduce its quality?
Resizing down to a smaller size usually keeps good quality. Enlarging a small image to a much larger size can reduce sharpness, since extra detail cannot be created from nothing.
Should I crop or resize my photo for Instagram?
If your photo's aspect ratio doesn't match Instagram's format, cropping first prevents distortion. Resize afterward to reach the exact pixel dimensions you need.
Does Instagram automatically resize my photos?
Instagram adjusts uploaded photos to fit its display formats, but this can crop parts of your image. Resizing beforehand gives you more control over the final composition.
What aspect ratio works best for Instagram posts?
Square (1:1) and portrait (4:5) ratios are widely used because they display well in the feed grid and on individual post pages without significant cropping.
Can I resize a landscape photo for an Instagram post?
Yes, landscape photos can be resized to 1080 by 608 pixels for feed posts, though square or portrait formats often display larger on mobile screens.
