I was referring to the limits of eye movement that restricts the practical
size of parallel images to a rather small 2 inch center to center
separation. Crossed images may be of just about any size. From the right
distance you could cross view roadside billboards or even twin buildings of
identical architecture. Large scale stereo is definitely more enjoyable than
small scale parallel images.

If your images of each type are the same size, yes the crossed view will
have an appearance of being smaller, due to what I call projection effects.
I was not referring to this effect.
