How to change the console font size

How can I change the font size in a console app on Windows? Simplest way? What is the difference between changing console color using system("") and windows.h?

You can change the font size using SetCurrentConsoleFontEx.
Below is a small example that you can play around with, make sure you #include <cwchar> and #include <windows.h>

CONSOLE_FONT_INFOEX cfi;
cfi.cbSize = sizeof(cfi);
cfi.nFont = 0;
cfi.dwFontSize.X = 0;                   // Width of each character in the font
cfi.dwFontSize.Y = 24;                  // Height
cfi.FontFamily = FF_DONTCARE;
cfi.FontWeight = FW_NORMAL;
std::wcscpy(cfi.FaceName, L"Consolas"); // Choose your font
SetCurrentConsoleFontEx(GetStdHandle(STD_OUTPUT_HANDLE), FALSE, &cfi);

std::cout << "Font: Consolas, Size: 24\n";

If you choose Arial or others, you may have to give it a font size width. For more information.

The difference between system() calls and using Windows.h is that system() calls are resource heavy and unsafe. More information here.
