Logo issue on mobile device

I have replaced the logo at the top of the page with one I created. It works fine on desktop devices but has an issue on mobile devices. The theme is supposed to be mobile responsive. When my phone is held vertically the logo is very small but when the phone is turned horizontally the logo displays correctly. I want the logo to be full width in any orientation. What do I need to change?
