Information

• Dummy pages are usually small versions of an entire page, although they may be full-size versions of a small publication. The sheet is divided by grid lines which are a set of non-printing lines that help editors and designers guide placement of elements.

• Your elements will need to fit across one or more of these column divisions, and your copy goes down the divisions, column by column.
  
• Tabloid-sized newspapers often use 5-column grids and broadsheet newspapers often use 6-column grids.
