You need to experiment with a range of different fonts for your magazine, creating a clear house style that suits your genre and appeals to your target audience. Look at your research and the range of fonts each magazine uses, each of these fonts has a purpose and function and has been selected for a specific reason. Your magazine should attempt to do the same, selecting fonts to suit purpose and create a clear house style.
You will also need to experiment with your Masthead for your magazine, this is the branding for your product and is incredibly important. You should create 3 different Masthead designs and evaluate the pros and cons of each design before deciding on a final piece.
