Resize Logo?

Hello, I am trying to resize my logo on my website easyhassle.com
I am currently running the theme Type by Design Labs
I can’t really give the desired dimensions simply because I do not know; I was going to fiddle around and see what size fits the website’s layout. The logo looks way to small right now, though. so if you could point out how I could go about changing the size, that’d be great.
Thanks for your help!
