Which orientation is best suited for spreadsheets and slideshows?

Landscape mode is best suited for spreadsheets and slideshows because it provides a wider horizontal space, allowing for more data to be displayed side-by-side. Spreadsheets often contain multiple columns and rows that require visibility across a larger surface area to effectively view, analyze, and compare data. Similarly, slideshows benefit from landscape orientation as it aligns with the typical aspect ratio of computer screens and projectors, making presentations more visually appealing and easier for audiences to follow. This orientation helps to utilize the screen space optimally for elements such as charts, graphs, and images, which are often displayed in a wider format.
