@harish: I see that you have added content in “Appearance => Theme Options => Promotion Headline Options”. We have created this area just for few line of bold promotion text. That is why the font is bigger. So, if you want normal font size text in homepage, then disable that Promotion Headline. You can set static front page and add content in that page. So, just create a page and write in content. Then go to “Settings => Reading” and in “Front page displays”, check option “A static page (select below)” and select the page that you want to show in home from “Front page”
