(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)

SDL_GetWindowSizeInPixels

Get the size of a window in pixels.

Header File

Defined in SDL_video.h

Syntax

void SDL_GetWindowSizeInPixels(SDL_Window * window,
                               int *w, int *h);

Function Parameters

SDL_Window *	window	the window from which the drawable size should be queried.
int *	w	a pointer to variable for storing the width in pixels, may be NULL.
int *	h	a pointer to variable for storing the height in pixels, may be NULL.

Remarks

This may differ from SDL_GetWindowSize() if we're rendering to a high-DPI drawable, i.e. the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the SDL_HINT_VIDEO_HIGHDPI_DISABLED hint.

Version

This function is available since SDL 2.26.0.
