- Acme Themes

We think we have finally understood your questions. By default in the front-page excerpt will display but in the single page full content will display in the free theme.
However in the pro theme, you can display either excerpt or content with number of words too in the front-page, which is more reliable for your requirements too.
Please check out pro theme here http://www.acmethemes.com/themes/acmeblogpro/.
