Generally speaking, it was better to choose a size tablet to read a PDF-based e-book. This was because a PDF-based e-book was usually divided into chapters, and there might be some space between the chapters to maintain the reading comfort. Therefore, the larger screen could better display the chapter information in the PDF-based e-book and provide enough distance for the eyes to maintain a comfortable position. Of course, the specific size of the tablet would depend on the individual's reading habits and needs. If you're used to reading on a smaller screen, you can choose a smaller tablet. But if you're used to reading on a larger screen, you'll be better off choosing a larger tablet.
