What is 1080×1350 used for?
1080×1350 is the Instagram portrait post — a 4:5 aspect ratio, taller than it is wide.
It is the largest image the Instagram feed allows, so it takes up more of the phone screen than a square post as people scroll — which is why creators favour it for reach. It also works well for portrait Facebook posts. For a square post use 1080×1080, and for stories or reels use 1080×1920.
How to resize to 1080×1350
- Upload your image (JPG, PNG, or WebP) — the target is already set to 1080×1350.
- If your image is not already 4:5, untick 'Keep the original shape' or crop it to 4:5 first.
- Click Resize, then download your 1080×1350 portrait image.

How do I resize an image to 1080×1350?

What is 1080×1350 used for?
1080×1350 is the Instagram portrait post size, a 4:5 aspect ratio. It is the tallest image the Instagram feed allows and takes up the most screen space on a phone, which is why portrait posts often get the best engagement. It also works for Facebook and other feeds.
Why is 4:5 better than square on Instagram?
A 4:5 portrait image occupies more vertical space in the mobile feed than a 1:1 square, so it fills more of the screen as someone scrolls and tends to draw more attention. Square (1080×1080) is still safe, but portrait maximises presence.
Will resizing to 1080×1350 crop my photo?
With 'Keep the original shape' unticked, the image is stretched to the 4:5 frame. If your photo is a very different ratio, crop it to 4:5 first so subjects are not distorted, then resize here.
Is my image uploaded to a server?
No. This tool runs entirely inside your browser. Your image never leaves your device, so nothing is uploaded anywhere.
