First: Please forgive me if and when I don´t always use the right words.
But the german forum is.. Well let´s say it´s not usable for new users...
My problem is the following...
I wanna create another "keep calm shirt" (no we don't have already enough of them

Therefor I have to set the "and" in smaller letters and maybe a different font type.
But when I change the size of the font the lines/spaces between them get different.
My opinion is that it is calculated by the majority of the fonts (in my example the bigger ones are 144 and the smaller "and" is set to bee 100) ..
How do I get the exact same space between the lines?
I tryed "distance betwenn the lines" in the upper menun bar and the tools on the second picture but all I get is that either ALL lines change or NONE of them...
Might sound like a simple and silly question but for a tech noob some little creative ideas (bad combination I know ^^) like me it is a major task ^^
So PLEASE...
Keep Calm And Help ME ^^
Thanks a lot
