When you look at the galaxy is the matter spread out horizontally or veritically? or both?

When you look at it from the ground you see a kind of whitish long cloud across the sky.
Its shape is that of a flat spiral with several branches (we sit in one of them). Flat means that the spiral is quite extended along its plane of rotation and its thickness is relatively small.

Depends entirely on the observer. It is simply a matter of perspective.
Consider I am standing on the North Pole and looking straight up. I guess that's pretty vertical - and someone on the South Pole would be looking straight down (according to me) and straight up, according to them - all the while a person on the equator looking in the same direction as either one of us would naturally consider he was looking horizontally!

we are in the galaxy where there's no horizontal or vertical, but when we are standing on the planet, that when we can have both hor. & ver.
