Please briefly describe the difference between portrait and landscape orientation, when each is used, and how to change the page orientation.
What will be an ideal response?
- Portrait and landscape orientation: Excel has two ways to print on a page. Worksheets printed in portrait orientation are longer than they are wide. In contrast, worksheets printed in landscape orientation are wider than they are long.
- When each is used: By default, Excel is set to print pages in portrait orientation. Many worksheets, however, include more columns of data than fit on pages in portrait orientation. These pages look better and are easier to understand when printed in landscape orientation.
- Changing the page orientation: You can change the orientation of the worksheet by clicking the Page Layout tab on the Ribbon, and then, in the Page Setup group, clicking the Orientation button. You can then click Portrait or Landscape on the menu.
