The horizontal orientation of the input method on Apple’s mobile operating system, iOS, refers to the display and utilization of the on-screen typing interface when the device is held in a wider, rather than taller, configuration. For instance, when an iPhone or iPad is rotated so the long edge is parallel to the ground, the keyboard typically expands in width, offering a different layout and potentially more keys than its vertical counterpart.
This alternative arrangement provides increased screen real estate for the keyboard, which can improve typing speed and accuracy. Historically, this capability has been a standard feature, evolving alongside screen size and device capabilities. Its availability promotes greater efficiency for tasks requiring extensive text input, such as composing emails or documents on mobile devices.
