I am trying to find a way to set Display size according to screen size.
Different monitors should be able to support it.

Is there a already something which I can use, if not then how can I achieve something like this on my own.

Probably you want al_get_monitor_info.

e.g.

#SelectExpand
  1#include 
  2#include 
  3
  4int main(int, char* []) {
  5  al_init();
  6  int c = al_get_num_video_adapters();
  7  for (int i = 0; i < c; ++i) {
  8    ALLEGRO_MONITOR_INFO info;
  9    if (al_get_monitor_info(i, &info)) {
 10      printf("%d. (%d, %d)-(%d, %d)\n", i,
 11       info.x1, info.y1,
 12       info.x2, info.y2);
 13    } else {
 14      printf("%d. no info\n", i);
 15    }
 16  }
 17  return 0;
 18}

[edit] or maybe al_get_display_mode if you want to know what fullscreen modes your monitor will support.
