(This function is part of SDL_ttf, a separate library from SDL.)


Create a font from a file, using a specified point size.

Header File

Defined in <SDL3_ttf/SDL_ttf.h>


TTF_Font * TTF_OpenFont(const char *file, int ptsize);

Function Parameters

const char * file path to font file.
int ptsize point size to use for the newly-opened font.

Return Value

(TTF_Font *) Returns a valid TTF_Font, or NULL on error.


Some .fon fonts will have several sizes embedded in the file, so the point size becomes the index of choosing which size. If the value is too high, the last indexed size will be the default.

When done with the returned TTF_Font, use TTF_CloseFont() to dispose of it.


This function is available since SDL_ttf 3.0.0.
