Resize skin text

Hi, I would resize a text in the skin that I use but I can't understand where to change it.
Also I try to change in the config of the skin this but nothing happens:

<!-- text settings that vary from the defaults -->
	<flags id="text_font" value="fonts/helveticaneueots" />
	<integer id="text_size_small" value="7" />
	<integer id="text_size_normal" value="8" />
	<integer id="text_size_large" value="9" />
	<flags id="hint_font" value="fonts/helveticaneueots" />
	<integer id="hint_size" value="8"/>
	<flags id="control_font" value="fonts/helveticaneueots" />
	<integer id="control_size_normal" value="8"/>
	<flags id="menu_font" value="fonts/helveticaneueots" />
	<integer id="menu_size_small" value="7"/>
	<integer id="menu_size_normal" value="8"/>
	<integer id="menu_size_large" value="10"/>
	<flags id="title_font" value="fonts/helveticaneueots" />
	<integer id="title_size_large" value="12"/>
	<integer id="title_size_normal" value="10"/>
	<integer id="title_size_small" value="8"/>
	<integer id="title_style" value="semi-bold"/>
	<flags id="html_font" value="fonts/helveticaneueots" />
	<flags id="pitch_font" value="fonts/helveticaneueots" />

How i can change it?
I hope in your help and sorry for my bad english. Thanks.
