9. How do you get scalable Computer Modern fonts?

Answer

Use the type1cm package by David Carlisle.

If you do not use this package, the default Computer Modern font is only available in a few predetermined, bitmapped font sizes, which will not scale nicely should you happen to desire a different size. This package solves that problem by making LaTeX use a truly scalable PostScript version of the Computer Modern font.

Using scalable Computer Modern, even if you do not need any non-standard font sizes in the document itself, has the additional advantage of decreasing the size of the generated PostScript and PDF files. It also makes those files more readable (e.g. in Adobe Acrobat Reader) at magnifications other than 100%, and it helps to solve printing problems (see also the page on PDF generation).

Example usage

In the preamble:

\usepackage{type1cm}

Whilst defining a custom chapter heading format:

... \fontsize{60}{62}\usefont{OT1}{cmr}{m}{n}\selectfont} ...
