Same here; font is huge on catalina. It seems like this is the culprit: static double get_scale(void) { float dpi; SDL_GetDisplayDPI(0, NULL, &dpi, NULL); #if _WIN32 return dpi / 96.0; #elif __APPLE__ return dpi / 72.0; #else return 1.0; #endif } I found changing it to dpi / 192.0 to be fairly comfortable. It wouldn't be too hard to add a scale option and change to `return (dpi * scale) / 192.0`. The "right way" is probably to do that but also get scale by checking the screen resolution; I'd go by height due to the increasing adoption of ultra-wide monitors: static double get_scale(void) { SDL_DisplayMode dm; SDL_GetDesktopDisplayMode(0, &dm); return dm.h * scale / 786.0; } Edit: works on my win10 and arch boxes.
