SDL2 window size is bigger than it should be

I'm trying to create a window, let's say 400x400:

SDL_Init(SDL_INIT_VIDEO);
Uint32 mode = SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE;
SDL_Window* window;
SDL_Renderer* renderer;
if (SDL_CreateWindowAndRenderer(400, 400, mode, &window, &renderer))
    return 2;
if (!window || !renderer)
    return 2;
SDL_RenderClear(renderer);
SDL_RenderPresent(renderer);
SDL_Event event;
int quit = 0;
while (!quit)
{
    while (SDL_PollEvent(&event))
    {
        if (event.type == SDL_QUIT)
            quit = 1;
    }
}
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
SDL_Quit();

I see a window filled with black pixels. However, the window's size is 500x500 withouth borders, and 502x540 with them, but why?

On Windows, the OS may stretch your window in the case when you are using a high DPI monitor. You can disable this stretching using:

SDL_SetHint(SDL_HINT_VIDEO_HIGHDPI_DISABLED, "1")
