Portrait and Landscape A4 Paper
A4 paper can be used in two directions: portrait and landscape.
Portrait: The paper is standing up. It is taller than it is wide. We use this shape for school homework, letters, and essays.
Landscape: The paper is lying sideways. It is wider than it is tall. We use this shape for charts, tables, and wide pictures.
The size of the paper does not change when it is tilted. Only the width and height switch places.
| Position | Width | Height |
| Portrait | 8.27 inches | 11.69 inches |
| Landscape | 11.69 inches | 8.27 inches |
For example, when we write essays in school it usually looks good in portrait mode. A wide timetable or chart may be easier to read in landscape mode.
