Original Answer(2016): You can use soft wrap, first solution is right click on the left of line where show line numbers and check Use Soft Wraps.
Another way is set it from:
File > Settings > Editor > General > Use soft wraps in editor
Also You can set Right margin for your editor from :
File > Settings > Editor > Code Style > Right margin (columns)
