Effective PPI

[HeyHector]

Sometimes when I make an image larger or smaller the Effective PPI data on the Information pane changes into a format that I don't know how to read.

I'm attaching an example for visual reference, but usually my image will be 300ppi and when I modify the size the Effective PPI will turn into something like 452ppi. Sometimes however it'll be 291x284.

What does that even mean?

I forgot to include the image

It's out of proportion. The width is 291ppi and the height is 284ppi. If you're holding Command and dragging a corner to change the size, include the Shift key to keep it proportional.

Migintosh: That's it!  Now it makes sense, thank you.
