Observer Music Monthly, Observer Sport Monthly and Observer Woman will all close, although the Observer Food Monthly supplement will remain.
The redesign will also see the newspaper be restructured as a four-section paper, consisting of news, sport, a review section and the Observer magazine.
Business and financial coverage will be incorporated into the main news section, with travel coverage being moved into the new look Observer magazine.
The restructure comes as the newspaper's parent company, Guardian News & Media, has reopened its voluntary redundancy scheme.
The company has already lost around 60 employees to the initiative, and shed around £10 million from its editorial budget this year.
