    Hi, @Ahmet Orun

    Please refer to the similar thread: How to set font for single control in Dialog?
    And RLWA32's answer:

    OnInitDialog:

    	// TODO: Add extra initialization here
    	// 
    	// class member 	CFont m_NewFont;
    	LOGFONT lf{};
    	CFont* pFont = m_button1.GetFont(); // Get initial font
    	pFont->GetLogFont(&lf); // Use LOGFONT to get font information
    	lf.lfHeight = 120; // Use to create 12 point font
    	m_NewFont.CreatePointFontIndirect(&lf); // Create a 12 point font
    	m_button1.SetFont(&m_NewFont, TRUE); // Have edit control use the 12 point font
    	return TRUE;   
    

    Best regards,

    To change the text size of a button, the font used for its text display must itself be changed.

    So you create a new font and SetFont() it to the button.

    If you want to change only the text size, it is more complicated, first querying the metric of the currently used font,

    Then, a new font with only the size changed is created from that information and SetFont() is performed.

    If the button is on a dialog, you can also put the font size in that resource, as in the following example.This method affects all controls belonging to the dialog in question.

    DIALOGNAME DIALOGEX 0, 0, 300, 100

    STYLE DS_SETFONT | WS_POPUP | WS_CAPTION | S_SYSMENU | WS_THICKFRAME

    FONT 10, "MS UI Gothic", 400, 0, 0x1
