Getting text render component size

Hi. I’m making a blueprint which splits a string into two or three others using a delimiter. I want each line to scale up or down to make a blocky looking…erm… text block.

So if i had:

This is what i’m<n>trying<n>to do, ok?

3 text render components will take a line each making

This is what i’m
to do, ok?

I’ve got this far, but I want it so all the lines scale up to a fixed width, so the ‘trying’ line will have the font size adjusted much larger than the other two.

So, to cut a long story short, is it possible to find the bounds, or even just the length (in units, not characters) of the text object once it’s created, so I can do some scaling magic?

Thanks in advance.
