Use rotating.sty for wide tables/figures

You can use the rotating package to automatically rotate wide figures or tables. It provides {sidewaystable}/{sidewaysfigure} as a alternatives for {table}/{figure} and rotates the environment content by 90°. The direction of the rotation can be set with package options clockwise or counterclockwise; if you set twoside as class or package option the tables/figures are rotated by extra 180° on odd pages.

PS: Use booktabs for a nicer styling of your tables 😉

Add a prefix to your labels

To keep track of (the target of) your labels you might want to add a prefix to their names indicating the thing they are referring to. E.g. sec for sections, eq for equations, fig for figures etc. It is common to separate the prefix with a colon from the label name like in the following example:

Then when you read your code you always know that \ref{sec:test} refers to a section.

In some cases the colon can cause troubles, e.g. when you type a french document with babel, varioref, hyperref and cleveref (see this and this post on TeX.SX for example). In that case you may use another character to separate the prefix.

scrpage2 is obsolete

With KOMA-Script version 3.12 the bundled package scrpage2 became obsolete and should no longer be used. Instead use the new package scrlayer-scrpage, which provides nearly the same interface but has much more power than scrpage2. For example with the new package instead of

you can use

to set the same mark content for plain and normal style pages. That is shorter and is more consistent: For instance if you have a more complex definition than \pagemark now there’s only one place to make changes.

For more details check the manual: scrguien.pdf (or the german version scrguide.pdf), chapter 5.

Paragraphs – the right way

in LaTeX the only two regular ways to end a paragraph are an empty line or the \par macro. Thus

and

is basically the same.

Please do not use \\, \newline or anything else to “end” a paragraph; it is considered to be bad style and actually wrong: From LaTeX’s point of view this only ends the line but belongs to the same paragraph. Therefore the indention or skip between paragraphs can’t work properly.

Removing page numbers

The traditional way to avoid displaying page numbers is using the command \pagestyle{empty}. Another way, which also omits pane numbers in the table of contents, is:

If you use hyperref, check that required hyperlinks still work.
