   According to this video the length of basis is r. It grows as we further from the origin . Why?

   There is not really a "length" of it, but you can consider how far you move if you move by a small ##\epsilon \hat \theta##, the length increases with the radius.

   Thanks. That makes sense. But why would the 'length' be r as Pavel Grinfeld says in the video.

   Set ##\epsilon=1##. With 2 pi you get a length of 2 pi r, with 1 you would expect a length of r. Sort of.
