LaTeX is a powerful document preparation system commonly used by researchers, academics, and professionals to create high-quality documents. One of the significant advantages of LaTeX is its ability to handle various fonts and text sizes effortlessly. In this article, we will explore how to change the font size in LaTeX documents.

Questions and Answers:

How do I change the font size for the entire document?

If you want to change the font size for the entire document, you can use the document class option ’12pt’ or any other desired size at the beginning of your LaTeX document. For example, `\documentclass[12pt]{article}` will set the font size as 12pt for the entire document.

In conclusion, LaTeX offers a range of options to change the font size in your documents. Whether it is for the entire document, specific text, section headings, or mathematical equations, adjusting the font size is easily achievable.
