Hi, i read before that the orthographic size is roughly supposed to be half the vertical screen size for pixel perfect but does this still apply to the iPad?
Not roughly half, but exactly half. The iPad’s display is just another screen so there’s nothing special about it.

I make it 1/4th on iPad actually, so 1 Unity unit = 2 pixels. That way I can just add higher resolution textures, move a few things, and everything is about the same as on iPod. Otherwise you have a much bigger playfield, which in my games isn’t desireable - might be different for your games off course.
