Take a magazine, newspaper or book that includes images and text. Lay tracing paper over the top of three spreads (both left-hand and right-hand pages). Using a pencil and ruler, carefully trace the grid underlying the page layouts. Remember to remove specific text elements or images, and to only draw the grid lines. Note column widths and margin sizes at the top, bottom, and to the left and right of the main body of text. Is your document based on a two-column, three-column, or another type of grid? Which elements stay the same on each page, and which change?
This is a two column grid system. The margin size on the bottom stays the same, while the margin size on the top and sides change on both sides. The width on the column also stay the same on both pages.
This is also a two column grid. On the left hand side the bottom margin size stays the same, while the margin size on the top and both sides change. The column width is the same.
On the right hand side non of the side-, top- or bottom margin is the same. They all change. The only thing that remains the same is the width of the column.
On the third spread there is a three column grid. The width on the columns are the same, and the width between the columns are the same. All of the columns also have the same top and bottom margin size. On the left hand side the margin is slightly bigger than on the right hand side.
The page on the right has a photo on it that fills the whole page. The top-, bottom- and right hand side has the same margin size. But the left hand margin size is smaller.
