Rotate your screen to change the Kindle's position.
The words on a Kindle can run in any of four directions. If you hold the device horizontally, the screen must use landscape mode, and the Kindle's buttons can run along the device's left or right side. If you hold the device vertically, the screen must use portrait mode, and the Kindle's buttons can run along the device's top or bottom side. A horizontal orientation resembles an open book, but you may prefer a vertical orientation, which looks like a single open page.
