When I design an image with dimensions of 1080×1920, which are the dimensions for Instagram stories, the image becomes unclear when I save it. I have to save it in a larger size to ensure clarity, but when I resize it, it no longer works and I can't publish it on stories because the size has changed."

Also, you say you're saving a LARGER size? When you enlarge an image in Photoshop it's not resizing it as much as it is stretching it and filling in blanks. If you were shrinking the image it wouldn't have the same issue. For enlarging images so you maintain quality you should consider using an AI software. A popular one is Topaz. It does a great job upscaling.

Try changing 300dpi (print resolution) to 72dpi (screen resolution). It will increase the dimensions of the file 4.17x the size while keeping the pixel size.

So, uncheck resample and change 300 to 72.

The ppi number is completely irrelevant on screen. It doesn't apply, it doesn't change anything.

On screen, the image pixels align to the screen pixel grid.

There is only one resolution on screen, and that's the physical screen resolution.

If your screen is 1920 pixels wide, an image 1920 pixels wide will take up the full screen width.
If the screen is 3840 pixels wide, that same image will take up exactly half the screen width.

Ppi has nothing to do with it.

Ppi is a print parameter. On paper there is no such pixel grid, and so one has to be invented. That's what the ppi number is.

Yes, but the original post asks about quality viewing on screen. If it's 300dpi at the pixel size it would appear very small. At 72dpi it will appear at the size uploaded to social sites. It is very much a factor, mr
