I have just noticed that the units in the vertical rulers in photoshop are a different length than the horizontal rulers. For example, in a 14x11 inch image at 300 ppi, if I zoom at 29% I can literally measure my screen with a real-life ruler and see that the horizontal inches correspond precisely with the real-life ruler but the vertical inches do not. The vertical inches are longer than the horizontal inches. My pixels are square, fyi.
I asked Adobe tech support about this and they said that every version they checked did the same thing. They concluded that it was "by design" though they were at a loss to explain it.
WHY? Why on Earth would this be the case? I use Photoshop for illustrations that are meant to be printed and it is totally inconvenient to not be able to preview the actual aspect ratio of my art. There is a NOTICEABLE stretching effect. I hate it. Make it go away. Please.
