I decided to look at existing magazines and what layout grids they have used to create the page design. Looking at whether the pages are mirrored and the sizes of the margins, gutters and how many columns/bars they have used in their grids and whether the grid is consistent throughout the magazine.
I looked at the magazine Kingpin which I am using to look at what type of grids they us. Below are a few o my images of the test I carried out using tracing paper on the top of the magazine.
4 bar grid – 4cm columns – 0.3cm + 0.4cm gutters – this layout is almost constant throughout but varies with the design.
