Unlike a regular Mac computer or Windows PC, you cannot change the screen resolution of your iPad; but Apple included an accessibility feature that allows you to make the text larger or smaller and change the font size by using a zoom. This option is not enabled by default, but this tutorial explains how to turn it on; this particular setting can be enabled or disabled at will, so it will not get in your way unless you explicitly try zooming in or out. Once you get familiar with this preference, you will probably leave it on: briefly, it offers the same convenience as using the pinch in or pinch out finger gesture to zoom in or out of pictures and web pages - but magnifies every element visible on the screen, and also lets you pan and move the screen around.
Follow these steps to turn on and enable the zoom magnifier on your iPad:
Off" by default. Tap on it.
Let's now explain in details the finger gestures to control the iPad zoom.
To zoom in, or to zoom out - Simply double-tab anywhere on the screen: as long as you have enabled the Zoom in your settings, this command will turn the zoom on or off, making text larger, as well as any other items visible on the display.
To move the screen while zooming is enabled - You need to use three fingers of your choice and pan around the glass display to move the current screen focus around and see other parts of the image you normally see in whole (1:1 scale, no zoom).
To increase or decrease the iPad default zoom level - Here too, use three fingers to double-tap in a special way. Tap once with three fingers, and tap another time quickly (still with three fingers), but keep your fingers on the screen. Then, while still keeping your fingers in constant contact with the glass display, move up to increase the zoom (and zoom in further still), or move down to zoom out. Then, release your fingers and your iPad will keep the custom zoom level you chose (which is previewed in real time).
Perhaps to avoid puzzling surprises, Apple disabled this option by default; once you have become accustomed to it, you'll be able to magnify the screen at will, and probably never by accident since three-finger zoom commands are too unnatural to occur accidentally.
