Emacs with smaller font size -> Text doesn't align

I have a problem with Emacs (which is a great editor by the way), when I change the default font size and font, my text doesn't align anymore.

In use it in vhdl-mode, and it is really开发者_运维知识库 annoying, that the text doesn't align. In other editor the text-alignment is fine, even though I have modified it in emacs.

Anyone their have a solution to this problem, rather going back to default font and default font-size?

When you changed your font, were you careful to change it to a fixed width font? When you say it looks fine in another editor, is that editor using the same font?

You need to make sure that you use a fixed width (monospace) font in emacs or any other text editor to get text to line up properly. My guess is you picked a proportional font in emacs and you have a fixed width font in the other editor.
