Questions tagged [string-length]

String length most commonly refers to the number of characters contained within a string. However, it could also mean the screen space a string takes up when printed.

This tag should be used for either of the two following types of questions:

  1. Those dealing with the number of characters contained within a string.
  2. Those dealing with measuring the size of a string (in pixels, millimeters, etc.) when it is printed on a screen.
