As a part of our Adobe Indesign templates, here is a 50+ pages Magazine template that you can download and use it to create a magazine. The download contains InDesign files that are compatible with the latest versions of Adobe InDesign.
If you are using older versions of Adobe then use .idml file in the zip folder. As always this is easy to use and you can customize the template as you like. The layout and the dimensions of the magazine is A4.
