Control the width of Text using a slider in After Effects

I made this tutorial after seeing two separate forum questions where people wanted to control the width of text in pixels with a slider. This tutorial shows you how to use a Javascript expression to do just that. This keeps the scale correct, but lets you control how many words per line you want and makes it easy to adjust.

The expression appears complicated, but I take you through it line by line, explaining what each element does. But if you’re not interested in code, which is totally fine, then you can download the preset from the link below.
