Text in Layout - help for a beginner please!

Hello,
I am very new to Rhino and to layouts. I’ve created some “details” and added text but the text always appears in a tall column, even if the detail I’ve created is wide. I’ve adjusted the text height but it just makes a taller column whereas I want to fill the box (ie with longer but fewer lines of text). I’m not sure what I’m doing wrong.
Thanks for your help,
Gaynor
