You can't. The TextBox has a FontSize property, and that's what size the font is. If you want to change the size of selected text, I think you're going to have to fiddle around with a RichText control.

If you badly want to use a TextBox...let's say your religion bans you from using anything with the word Rich in it or maybe the RichTextBox has personally offended you in some way.

Then, you would have to overwrite the Paint event using subclassing and draw the text as you want it. Of course, this method would take a lot of work and is already done for you in the RichTextBox...but hey, maybe you just really don't like it.

That's not what he asked. He wants to change the size of JUST the text selected in the textbox. Unselected text will remain the size defined by the textbox.

InitializeComponent();
myFontBig = new Font("Andaluse", 16, styleBld);
myFontSmall = new Font("Andaluse", 10, styleReg);
}
private void button1_Click(object sender, EventArgs e)
{
//string s1, s2;
Graphics gg = textBox1.CreateGraphics();
TextRenderer.DrawText(gg, "Hellow Mr Josip", myFontBig,
