I work in a cubicle, but it's the
corner cubicle, and is very spacious.

I'm surrounded by 2 solid walls, a cubicle wall, and a 2nd desk. My work area normally wouldn't have an L-shaped desk, but that 2nd desk gives me more space.
If I had to guess, I'd say my area is around 14' x 10', although my area is probably more like 20' x 10', since nobody sits across from my 2nd desk. I'm basically using 2 cubicles worth of space, and more.
I could have had my own office, but I don't want one. I wanted to be out in the main area with everyone else.
Having that corner cubicle is my consolation prize, I suppose.
We get something like this, so not cubicle.
I
wish I worked in an office like that.
Our cubicle walls are around 5'8" high, so you can't really see over them unless you stand on your toes.
They don't block out any sound, and all they do is isolate you from others. There's very little benefit of high walls except that it allows you to do some off-topic web browsing, and pick your nose without anybody finding out.
