A feature of a web browser, program, or digital interface to increase or decrease the size presented content.


This term refers to the general and unbranded function of a program that allows people to usually magnify content to make it more readable to them.

Commonly, there may be a sliding scale or a numeric percentage that is either always visible or collapsed in a menu to adjust screen magnification. With the onset of touchscreen computing and smartphones, people may also pinch to zoom.
