# Inserting a specific number of blank lines

I'm new to LaTeX and trying to format my Honors Thesis, which has very specific formatting rules to prepare the manuscript for publication. For instance, on the Abstract page, I am required to place 3 blank lines above and below my name and degree information. At the moment, this is the code I have for the abstract page:

\newpage

\begin{center}
\vspace*{1in}
ABSTRACT \\

\vfill
\singlespacing
TITLE SINGLE-SPACED IN ALL CAPS, SAME SIZE AS THE REST OF THE TEXT

\vfill %Should be 3 blank lines here.

\doublespacing
My name \\
My department \\
My degree

\end{center}

\vfill %Should be 3 blank lines here.

Put text of the abstract here.

%The abstract must not exceed 250 words.


As you can see, right now I'm just using the \vfill command, which I think looks spectacular but doesn't fulfill the formatting requirements exactly (although it gets pretty close when the abstract is 250 words). I've considered using the \vspace{} command, but I don't know how long 3 lines of text in Times New Roman size 12 font would be. Right now I'm using TeXShop to edit this document, which is a .Rnw file (I'm going to use Sweave). Right now, the default spacing is double-spacing (Most of the thesis is required to be in double-spacing) using the setspace package.

\vspace{3\baselineskip}\vspace{-\parskip} should work. But your center-environment will add some space, use better \centering if you want to avoid this. –  Ulrike Fischer Jul 18 '12 at 15:08

Use \vspace*{3\baselineskip} command for getting your requirement
Thanks - that seemed to work, although I did add \vspace*{-\parskip} and changed to \centering rather than the \begin{center} environment, as suggested by Ulrike. I also found that switching to \singlespacing after the "My department" line, and then switching back to \doublespacing before the text of the abstract, was helpful. Thanks everyone! –  romnoose Jul 18 '12 at 17:08
