C# – possible to get/set console font size in c# .net


I have seen posts on changing console true type font, console colors (rgb) but nothing on setting or getting the console font size. edit: reason = grid is output to console, grid has many columns, fits better in smaller font, wondering if possible to change at runtime rather than allowing default or configured fonts to take priority / override inheritance.

Maybe this article can help you


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using System.Drawing;

namespace ConsoleExtender {
    [StructLayout(LayoutKind.Sequential, Pack = 1)]
    public struct ConsoleFont {
        public uint Index;
        public short SizeX, SizeY;

    public static class ConsoleHelper {
        public static extern bool SetConsoleIcon(IntPtr hIcon);

        public static bool SetConsoleIcon(Icon icon) {
            return SetConsoleIcon(icon.Handle);

        private extern static bool SetConsoleFont(IntPtr hOutput, uint index);

        private enum StdHandle {
            OutputHandle = -11

        private static extern IntPtr GetStdHandle(StdHandle index);

        public static bool SetConsoleFont(uint index) {
            return SetConsoleFont(GetStdHandle(StdHandle.OutputHandle), index);

        private static extern bool GetConsoleFontInfo(IntPtr hOutput, [MarshalAs(UnmanagedType.Bool)]bool bMaximize, 
            uint count, [MarshalAs(UnmanagedType.LPArray), Out] ConsoleFont[] fonts);

        private static extern uint GetNumberOfConsoleFonts();

        public static uint ConsoleFontsCount {
            get {
                return GetNumberOfConsoleFonts();

        public static ConsoleFont[] ConsoleFonts {
            get {
                ConsoleFont[] fonts = new ConsoleFont[GetNumberOfConsoleFonts()];
                if(fonts.Length > 0)
                    GetConsoleFontInfo(GetStdHandle(StdHandle.OutputHandle), false, (uint)fonts.Length, fonts);
                return fonts;


Here is how to use it to list true type fonts for console,

static void Main(string[] args) {
   var fonts = ConsoleHelper.ConsoleFonts;
   for(int f = 0; f < fonts.Length; f++)
      Console.WriteLine("{0}: X={1}, Y={2}",
         fonts[f].Index, fonts[f].SizeX, fonts[f].SizeY);


Crucial functions: SetConsoleFont, GetConsoleFontInfo and GetNumberOfConsoleFonts. They're undocumented, so use at your own risk.
