# Controlling the spaces between paragraphs

In the IEEE latex package, I see that the paragraph spacing is set to zero (.cls file)

``````% Controls the spacing between paragraphs in lists.
% IEEE does not increase spacing before or after paragraphs
% so this is also zero.
% With IEEEtran.cls, global changes to
% this value DO affect lists (but not IED lists).
\parsep             \z@
``````

However, in the output PDF file, I see some spacings.

Why?

• I haven't used the IEEE latex package, but usually I would set parsep in the preamble via `\setlength{\parsep}{0pt)`. Can you try if that works? – altabq Oct 14 '14 at 9:08
• My bad, had a typo. The 0pt should be in {}-type brackets, not in regular brackets. So `\setlength{\parskip}{0pt}` – altabq Oct 14 '14 at 9:15
• `\parsep` is about paragraph spacing inside lists, not about normal paragraphs, for which the parameter is `\parskip`, usually set to `0pt plus 0.1pt`. Setting `\parskip` to zero will probably produce underfull boxes and columns with unequal heights. – egreg Oct 14 '14 at 9:40
• @AndrewCashner No, I meant `\parskip`. If there's no flexible glue in a column and the text height is not computed correctly, underfull boxes and unbalanced columns will appear. – egreg Oct 14 '14 at 16:10

It is difficult to answer your question without knowing your setup. If you have chosen the option `twoside`, you also have turned on `flushbottom` I presume, and then LaTeX will add space also between the paragraphs to stretch the page.

Try the option `oneside`, or add the command `\raggedbottom` as the last command in the preamble.

The class files defines `\parskip` as:

``````\parskip 0ex plus 0.2ex minus 0.1ex
``````

so check your code and packages that you not unintentionally have altered this definition.

• If you download the package and compile the bare_conf.tex, you will see the issue – mahmood Oct 14 '14 at 9:14
• @mahmood I am not able to install the class on my computer now. – Sveinung Oct 14 '14 at 9:29
