Change display size of maths equations in typst

Question

In typst I can set the font size using

set text(9pt, font: "Linux Libertine", lang: "de")

inside of #let project(title: "...", authors: (...), body) = {...}

I want to make a cheat sheet for an exam using typst and I would like to display all maths equations as small and tight as possible (>=9pt). I changed the font size but it appears that the size of displayed equations did not change. How can I do that globaly?

What I found in the documentation was this

display(
content,
cramped: boolean,
) -> content

but while the cramped option is helpful, I dont know how to set the display size of the equation and I dont know how to do that globally without needing to wrap every single of the many equations inside this function.

Answer 1

To change the size of math relative to the rest of your content, you can use

#show math.equation: set text(9pt)

which specifically resizes math. You may also be interested in the inline function which forces inline style for display equations.
