How do I set multiple paragraphs

[h1s-kunal]

Like how will I know at which coordinate the first paragraph has an end and set the box size accordingly for the 2nd para and onwards?

Basically, I'm trying to create a dynamic image like this How can I set the box size for "Hello!", then the next line and so on?
