Math Block Size
Obsidian supports the following LaTeX sizes, from smallest to largest:
\tiny
\scriptsize
\small
\normalsize (Default)
\large
\Large
\LARGE
\huge
\Huge
Method 2: Use \displaystyle (Best for fractions)
Sometimes equations (like fractions) look too small in line. If you want to force an equation block to use the full, large “display” format, add \displaystyle at the start of your code.
