 [Many people ask why the default margins are so damn large](https://tex.stackexchange.com/questions/71172/why-are-default-latex-margins-so-big) (also, in that question, they mention the package `geometry`; we have KOMA-script for that).
 The margins aren't too large: the (default A4) paper is.
 Only avid readers can process lines in excess of approx. 80 characters.

+All others suffer headaches and find texts like that hard to read.
 KOMA knows about that and the many other 'rules' aka conventions, producing the margins you see.
 
  There is very good reason books don't usually come in A4 or letter format.
  It is often much closer to A5, which suddenly *makes sense*: margins are small, the text fits nicely.
  It is nice to read and hold.
  If your document is an actual thesis of many dozens of pages, maybe look into using A5.
 
- To see it in effect, uncomment the options `a5paper` and `10pt` (we decrease the font size by 1pt, down from the default of `11pt`) in [the base file](yatt_thesis.tex) when calling the `documentclass`.
+ To see it in effect, uncomment the `a5` option (we decrease the font size by 1pt, down from the default of `11pt`) in [the base file](yatt_thesis.tex) when calling the `documentclass`.
  At this point, there is a reward for careful typesetting: specifying lengths etc. in absolute units will likely break the document.
  Having done all that jazz in relation to `linewidth`, `textwidth` and their siblings will scale everything accordingly.
  Nevertheless, not all things will come out right.
