Small size font problem

Hi guys, I have a question
I’m trying to make a ‘Text’ UI element in the world space like this video.
(http://unity3d.com/learn/tutorials/modules/beginner/ui/ui-canvas, At about 4:35)
But It doesn’t work…
When I set the text font size to something like 100, it appears but so big…
when set to 1 or less than 10, I can not read it.
what am I doing wrong??

In the video, the canvas size is 1 by 1, same as what I did…
I Attached the ‘Test’ Project I followed the video guide.
Please help me…!

Self-Answer.

It was font problem. I used trick to solve the problem.

  1. Set font size upper than 5.
  2. Change the RectTransform scale.
