How to reduce spacing?

In a Word document, how do I change the font without messing up the spacing? I need special characters...?

• Hello! I have this document with chemistry symbols and I need to make them appear. I don't know of any other way to do this than to change the font. So my document is originally set with Times New Roman and now I am changing to this font called "Fontrue" that is making my chemistry symbols appear and the letters are like identical to Times New Roman, but there is one problem, spacing is completely messed up with this new Fontrue. Any ideas? I have already tried changing the spacing between lines setting. Still weird spacing between lines. Because there are images in my document, I would like the spacing to be very exact. But I cannot manually change it because it is too long (and there are around 200 other files with the same problem). What are other settings I could try?

• Answer:

  The Format Paragraph dialog lets you set the line spacing to a specific value. This will force all lines to have the same space ("leading") independent of the heights of the characters (and/or objects) within the lines. So, for example, if you set a paragraph's line spacing to "Exactly" at "12pt", the height of an 18pt character within it would be truncated.
