LaTeX Template
A template for project and master's theses in LaTeX is available [here] as a zip-file.
Microsoft Word
If you (still) prefer to write your thesis in Microsoft Word, you have to make your own style. It is preferred that you adapt your style as closely as possible to the style of the LaTeX template. Have a look at the file thesis.pdf and try to use the same margins, font sizes, and so on. The font used in the template is Adobe Utopia. If you do not have this font, try to choose a similar font.
