UI Screen optimization problem

Hello Dear Unity Family.

I was make some interface with UI objects(Panels,Buttons bla bla)
example,starter my screen size 320x480,but when I select other screen size (480x854 or bla bla),UI objects distorted,slips.

infact I can make very nice screen optimization with Unity's GUI but GUI objects very very low quality(button texts,label texts very very look bad)therefore I want UI objects but I cant screen optimization.

Thank You.

 

You can make the UI behave correct on re sizing.
You may like to what the unity UI tutorials, especial the rect-transform tutorials.
