Hi, This might be a stupid question, but I'm struggling to change at once the font size in a drawing which has multiple blocks with many attributes. Its an old dwg file with a list of equipment, and in many cases, the equipment listed stretches out of its designated area. 

I have actually succeeded by changing the font to Arial Narrow via FORMAT/TEXT STYLE, but I didn't find a way to change the font size. Can you please help me?
