Mobile Site: Site Title Padding

Hi, I'm in the process of developing my website and I'm trying to get used to designing it. Everything looks good so far, except for when I load my website on my mobile browsers, the last letter is almost cut off. My phone is an iPhone 5S, and the site title has 19 characters. Is there a way to make the site title fit better maybe with a bit of padding or making the site title auto-adjust to the screen size if it's small screen? Thanks, guys!
