C# Richtextbox - Get text size after changing it by scrolling and holding ctrl

I have a richtextbox. When I'm holding control and spin the scroll wheel, the text size is changing. But how do I get the text size after changing it by ctrl + scroll? RichTextBox1.Font.Size is always 8.25.

Google did not help.

Use this code:

private void richTextBox1_KeyDown(object sender, KeyEventArgs e)
{
      float zoom = richTextBox1.ZoomFactor;
      if ((zoom * 2 < 64) && (zoom / 2 > 0.015625))
      {
            if (e.KeyCode == Keys.Add && e.Control)
            {
                  richTextBox1.ZoomFactor = zoom * 2;
            }
            if (e.KeyCode == Keys.Subtract && e.Control)
            {
                    richTextBox1.ZoomFactor = zoom / 2;
            }
      }
}

What you're looking for is the ZoomFactor of RichTextBox:

Gets or sets the current zoom level of the RichTextBox.

That's why you don't see the font size change.
