: How can I reduce type size in each line of a paragraph - Indesign or Illustrator? I would like to design a paragraph (full of text) where the font size for EACH new sentence changes in font

Try this: in menu window > utility > script In script panel open Application > Javascript and right-click on one file (example AddGuides.jsx) and select Show in Finder. Duplicate the file in Finder and rename in decreaseParagrph.jsx and now open it with simple text editor. Paste this code:

mySel = app.selection;
var myArray = new Array();
var myP = prompt("Choose your % of decrease","80");
var myPercentile = myP/100;

// this grep find all the sentences : [^.!?s][^.!?]*(?:[.!?](?!['"]?s|$)[^.!?]*)*[.!?]?['"]?(?=s|$)
var a = "[^.!? ][^.!?]*(?:[.!?](?!['"
var b = '"';
var c = "]? |$)[^.!?]*)*[.!?]?['";
var d = "]?(?= |$)";

// you must select text (or more texts)
if(mySel.length>0){
for(var i=0;i<mySel.length;i++){

//clear find/replace preferences
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences = NothingEnum.nothing;

//find the grep
app.findGrepPreferences.findWhat = a+b+c+b+d;

//and put into array
var myArray = mySel[i].parentStory.findGrep();

//for all elements of array (exept the first)
for(var o=1;o<myArray.length;o++){

//take the prevoius sentence point size
var myNewMeasure = myArray[o-1].pointSize;

//and transform it
myArray[o].pointSize = myNewMeasure*myPercentile;
}
}
}


Save decreaseParagrph.jsx file and return in InDesign, open the file with paragraph, choose the text box with text you want and double click on decreaseParagrph.jsx (in script panel), choose % of decrease and enjoy ;)
