The layout for print advertising should, whenever possible, carry the brand area the size of the corporate logotype. The font is preferably Corporate A. Corporate S is used for contrast.
Divide the height of the format in 11 or 13 parts (see Brand area) to get the height of the logotype = brand area height. In advertisements the brand area is primarily at the bottom of the page. No other elements may be placed in the brand area.
For really small ads make sure the minimum size of the logotype is 25 mm. The recommended minimum size for text in ads is 6 pt.
