Font size and dimensioning

OK so I am doing a drawing and learning how to add hatches. I have to add multileaders with text with SansSerif font. I open the Dimention Stylr Manager box and pick correct font. When I go type text it is so small I can't read it and it is not correct font.

Multileader styles are controlled independant of Dimension styles. Create a multileader style that uses the same text style, text height, arrow size etc. as your dimension style if you want your Mleaders to match your other dimensions. (MLEADERSTYLE)

Thanks. I am still trying to get my head around annotative dims and now this. This helped.
