I use the import images as planes addon. I get the image. But then I noticed when I use it on a 480p image, its the same size as a 1080p image. I don't understand....is it keeping the aspect ratio but displaying them as the same size.....? When I try to define my aspect ratio in the dimensions tab it blows up so large that I can't zoom out to see the actual image anymore. So I'm guessing these are 2 different things.

All I want is to display my image in the 3d viewport at the same aspect ratio as the image actually is.

I don't really understand the unit system in blender. I can make a cube 1 unit in the x direction, 1 unit in the y direction. What is this unit though? I'm used to units being pixels.

Think of it this way:

A scene in blender is created in a virtual world.

The units for that world and all of the objects are blender units (that coincide with meters. one blender unit is one meter, the units can also be set to imperial measurements or KM or mm if you wish)

When you import an image as a plane, it will create a plane that is one blender unit tall (that can be changed in the options as you import the image), and that has the aspect ratio of the imported image.

enter image description here

The number of pixels in the image does not determine the size of the plane.

If you need to create planes that are different sizes and have their size relative to their dimensions in pixels, you could do that manually using the information on this link:

Do not touch the aspect ratio on the dimensions for the render unless you know what you are doing and need to export an image that is using anamporphic pixels. Read: Rendered aspect ratio different from the viewport's camera view
