Changing site title width

Hi, I need to change the width of my site title so it’s not all squashed up.

I have made many changes to my theme over the last 3 years of using WordPress and I’m proud to have done it all on my own so far. I just can’t find the right bit of code to set the width for the site title though ??

If you take a look on the link I’ve provided you’ll see there are three lines of text for the title of my site.

I just want it to all be on the one line and I know I need to change the width value of something but I can’t find it!
