  Auto-scale text depending upon text length

  Posted by Chris Brady on October 1, 2019 at 11:16 am

  Hi all,

  Is there a way to auto-scale the text so it fits within a defined area of the composition, no matter the length of text.

  Example: The text ‘John Smith’ sits in the centre of the screen with a padding of 500 pixels either side. When the user changes the name to ‘Christopher Smith’ the text layer auto-scales down so 500 pixels padding remains either side of the text.

  Hope that makes sense. Thanks in advance!

  Add this to scale:

  var padding = 500;

  value * (width-padding*2)/sourceRectAtTime(time,false).width;

  To make sure the text stays in the middle, you could add this to the anchorPoint and then press ctrl+home to place it in the middle of the comp.

  var myWidth = sourceRectAtTime(time,false).width;
var left = sourceRectAtTime(time,false).left;
var myHeight = sourceRectAtTime(time,false).height;
var top = sourceRectAtTime(time,false).top;
[left+myWidth/2,myHeight/2+top]
