Get console screen size in Windows and Linux


Console application in both operating systems Windows and Linux measure the screen size using the number of columns and lines instead of use pixels. This because console mode allow only characters output inside the ASCII range and each character block have a fixed width and height size.



Get the console size (number of columns and lines) is a very easy task using the following snippets.

Code for Windows

CONSOLE_SCREEN_BUFFER_INFO csbi;

GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);

Height = (csbi.srWindow.Bottom - csbi.srWindow.Top + 1);
Width  = (csbi.srWindow.Right - csbi.srWindow.Left + 1);

Code for Linux

struct winsize ws;

ioctl(0, TIOCGWINSZ, &ws);

Height = ws.ws_row;
Width  = ws.ws_col;

Simply copy and past in your project code.
