Answer:
Portrait (vertical); Landscape (horizontal)
Step-by-step explanation:
The two most common types of layout that Roy can consider when making his magazine would be portrait and landscape. A portrait/vertical orientation is one in which the height is more than the width of a page. This is the orientation that most books and magazines have. The other type of layout that he could use is landscape, or horizontal, which is when the width is more than the height.
